Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a display adjustment device and system for a display device having a light emitting unit such as an organic EL, an inorganic EL, and an inorganic LED.
[0002]
[Prior art]
In recent years, the importance of self-luminous devices has increased due to the spread of blue LEDs and the development of organic EL display devices. A flat display device (flat display) is an important application of these self-luminous devices. In addition to these, the self-luminous display device includes inorganic EL, plasma display panel (PDP), fluorescent display device (VFD), field emission display (FED), and the like.
[0003]
Comparing a liquid crystal display device that has been widely used and a display device using a self-luminous device, the latter does not require a constantly lit light source such as a liquid crystal backlight and needs to be lit according to display information. Since only a certain part consumes electric power, there is an advantage in that it consumes less electric power than a liquid crystal display device. In addition, since the liquid crystal uses polarization control by birefringence, the display state changes greatly depending on the viewing direction, so-called viewing angle dependency is strong, but the self-luminous device has almost no problem. Furthermore, since the liquid crystal display device uses a molecular orientation change derived from the dielectric anisotropy of liquid crystal, which is an organic elastic material, in principle, the response time to an electric signal is 1 millisecond or more. On the other hand, the above self-luminous device uses so-called carrier transitions such as electrons / holes, electron emission, plasma discharge, etc., so the response time is on the order of nanoseconds, which is incomparable with liquid crystals. It is high speed and there is no problem of the afterimage due to the slow response of the liquid crystal.
[0004]
Despite the many advantages as described above, there is a problem of uniformity of light emission as a decisive problem when a self-luminous device is used. This problem of light emission uniformity can be roughly divided into two types.
[0005]
One of the problems is a so-called in-plane non-uniformity problem in which, when the area exceeds a certain level, the light emission characteristics vary depending on the location due to the non-uniformity of the manufacturing conditions of the light emitting part. This in-plane non-uniformity problem can be solved if the process study progresses and a uniform light emitting device can be manufactured. In addition, any measures may be taken on the manufacturing side before shipment to the market.
[0006]
A further important problem is degradation. Even if uniform light emission characteristics are shown at the beginning, the light emission characteristics are usually different due to deterioration of the device during use. In an image display device composed of a large number of pixels, it is inevitable that the accumulated light emission time varies depending on the pixels in accordance with image information to be displayed. For this reason, while using the device, a difference occurs in the deterioration state depending on the pixel, and the light emission characteristics differ.
[0007]
Many countermeasures have been proposed for these problems. For example, in JP-A-11-282420 and JP-A-9-198007, the luminance of each pixel is measured and stored in advance. A uniform display is achieved by performing control by feeding back the result of comparison with the reference luminance value.
[0008]
As is apparent from paragraphs 0008 and 0024, Japanese Patent Application Laid-Open No. 11-282420 describes only achieving in-plane uniform display of a display device, and correcting for deterioration after shipment of the device. Is not specified. On the other hand, in Japanese Patent Laid-Open No. 9-198007, paragraph 0058 specifies that deterioration due to secular change is adjusted. This Japanese Patent Laid-Open No. 9-198007 describes that statistical processing is performed using a personal computer. This personal computer uses only measured luminance or only data recorded in the personal computer in advance. Therefore, accurate display adjustment including a difference in the operation state (such as an integrated operation state) of the device is not performed.
[0009]
[Problems to be solved by the invention]
The method of adjusting deterioration due to secular change specified in Japanese Patent Laid-Open No. 9-198007 requires a special correction action to be performed by installing a light emitting device and an adjusting device, and is adjusted by a user who does not have expertise. However, as described in paragraph 0001, it is effective for maintenance of a large-sized display device for business use, but for personal use such as a mobile phone or a mobile terminal that is expected to rapidly spread in the future. It is preferable that the device can be maintained without being conscious of the actions generally performed by the user, and it is necessary to prevent the user from paying additional costs (or not being conscious of paying). In that respect, the above technique is extremely inadequate.
[0010]
Further, in the above-mentioned known examples such as Japanese Patent Application Laid-Open No. 11-282420 and Japanese Patent Application Laid-Open No. 9-198007, as described in the respective claims, the luminance is measured and the reference luminance is used. Is calculated, and input data for correcting the difference is calculated and fed back to the drive control unit.
[0011]
In order to perform feedback correction control of the luminance of the light emitting device, there are roughly two types of methods. One is to measure the actual brightness, input the expected correction data, then re-measure the brightness, and repeat this process until a uniform display similar to that before deterioration is obtained on the entire screen, so-called “repeat” Feedback control ”. However, this method takes too much time for correction adjustment, and is not practical at all in the case of a display device composed of a large number of pixels. Therefore, actually, as described in JP-A-11-282420 and JP-A-9-198007, the correction necessary for correction from the measured luminance using the characteristics of the input signal and the emission luminance is used. It is practical to perform calculation feedback control that calculates and calculates data and enables correction by one or a few luminance measurements. FIG. 6 schematically shows such a conventional luminance correction procedure. Light emitted from a device 1 equipped with a display device, such as a mobile phone or a mobile terminal, is transmitted to an adjusting device 2 including a light receiving unit. It receives light, measures the light emission luminance of the display device of the device 1, calculates and calculates correction data for luminance correction using the measurement result, and feeds back to the device 1. Further, the calculation result in the adjustment device 1 is stored in the personal computer 3 for the brightness correction statistical processing.
[0012]
However, for this purpose, correct correction data cannot be calculated and calculated unless the relationship between the input signal and the luminance characteristics is always constant. However, in almost all light emitting devices, the characteristics of the input signal and light emission luminance greatly change due to deterioration. As an example, typical qualitative characteristics of organic EL are shown in FIGS. FIG. 7 shows that the relationship between the input current and the light emission luminance is almost linear. From FIG. 7, it can be seen that the light emission luminance decreases with the operating time even with the same input current. Further, FIG. 8 shows the relationship between the applied voltage and the light emission luminance, but it can be seen that the applied voltage-light emission luminance characteristic is more unstable than the current-luminance characteristic of FIG. This characteristic also varies depending on the drive time (cumulative light emission time). From FIG. 9 showing the relationship between the driving time and the luminance, it can be seen that the emission luminance decreases nonlinearly as the driving time increases.
[0013]
Due to these non-simple characteristics, it is extremely difficult to perform correctable calculation feedback control in a short time and accurately only by measuring the light emission luminance. The same applies to inorganic EL and inorganic LEDs, and it is inevitable that the light emission characteristics themselves change with time, and there are similar difficulties.
[0014]
As mentioned above, it is expected that demand for self-luminous display devices and equipment equipped with them will surely advance in the future, and although display deterioration correction is very important, it has been reported so far. The prior art is insufficient, and in order to perform more accurate luminance correction, luminance correction combined with driving time and the like is necessary, and maintenance means that does not make the user aware of the maintenance is necessary.
[0015]

[0026]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of an embodiment of a display adjustment device according to the present invention will be described with reference to FIGS. 1 and 2 show a first embodiment of a display adjustment apparatus according to the present invention. The display adjusting device 10 calculates, for example, a light receiving unit 11 that receives light 22 emitted from a light emitting unit of a display device 21 mounted on a device 20 such as a mobile phone or a mobile terminal, and correction data for adjusting the display. And a processing unit 12 for processing and calculating. The device 20 has a built-in memory unit 23 for accumulating operation state data obtained by integrating the operation states of the display device 21. Here, the operation state data includes data related to at least one of the integrated operation time, the integrated operation temperature, the integrated drive current, and the integrated drive voltage of the light emitting unit. As described above, the operation state data of the display device 21 is read from the memory unit 23 of the display device, and the display adjustment device 10 processes the luminance data together, whereby more accurate luminance correction is performed.
[0027]
Normally, the device 20 is used separately from the display adjustment device 10 as shown in FIG. When performing display adjustment of the display device 21, as shown in FIG. 1, the device 20 is placed on the display adjustment device 10 so that the display device 21 and the light receiving unit 11 face each other. The device 21 emits light. Therefore, the light 22 from the display device 21 is received by the light receiving unit 11, and the display adjustment device 10 detects the luminance of the display device 21 and takes the detected luminance into the processing unit 12 as luminance data. At the same time, the display adjustment apparatus 10 and the device 20 are connected through an appropriate connection unit 13, and the operation state data stored in the memory unit 23 of the device 20 is transmitted to the processing unit 12 through the connection unit 13. If the display adjustment device 10 is provided with the charging terminal 14 so that the display adjustment of the display device 21 can be performed during the charging period of the device 20 , the convenience is further increased.
[0028]
The processing unit 12 stores in advance basic characteristics related to light emission luminance of the display device 21 as shown in FIGS. 7, 8, and 9. Therefore, the processing unit 12 uses the basic characteristics, the operation state data transmitted from the memory unit 23, and the luminance data captured by the processing unit 12 to use correction data for correcting the display of the display device 21. Is calculated. The calculated correction data is sent from the processing unit 12 to the device 20 via the connection unit 13, and the device 20 performs display adjustment of the display device 21 using the correction data.
[0029]
The display adjustment apparatus 10 does not necessarily include the processing unit 12 as shown in FIGS. 1 and 2, and may have a configuration without the processing unit 12 as shown in FIG. 3. The display adjustment device 10 ′ having such a configuration is used in the display adjustment system shown in FIG. 4, in which arithmetic processing means corresponding to the processing unit 12 is provided outside the display adjustment device 10 ′.
[0030]
In FIG. 4, the device 20 sends operation state data stored in the memory unit 23, for example, data relating to the accumulated operation time, accumulated operation temperature, and accumulated drive current, to the display adjustment device 10 ′ via the connection unit 13. The display adjustment device 10 ′ receives light 22 emitted from the display device 21, measures its luminance, and takes in luminance data. Therefore, the display adjustment device 10 ′ transmits the basic characteristics, the operation state data sent from the device 20, and the measured luminance data to the arithmetic processing unit 30 such as a personal computer. In response to this, the arithmetic processing unit 30 calculates correction data for adjusting the display of the display device 21, and sends this correction data to the display adjustment device 10 '. Upon receiving this, the display adjustment device 10 ′ transmits correction data to the device 20 to adjust the display of the display device 21. In this case, the basic characteristics of the display device 21 as shown in FIGS. 7 to 9 are stored in advance in the arithmetic processing unit 30, but these display adjustment devices 10 ′ are used for data confirmation / collection of the basic characteristics. It is also possible to use data from
[0031]
FIG. 5 shows a modification of the display adjustment system shown in FIG. 4. The arithmetic processing unit 30 directly transmits the calculated correction data to the device 20 instead of the display adjustment device 10 ′ to display the display device 21. Let them adjust.
[0032]
4 and 5, the arithmetic processing unit 30 installed outside is installed in a manufacturer, a seller, a display adjustment service provider, or the like of the device 20 or the display device 21. As a result, the display adjustment service is provided to the user of the device 20, and the collected data and the user information of the display adjustment service are stored, and used for the development of the next display device as the reliability test data of the display device. This is because it can be used as information on replacement sales. By using the data collected in this way for secondary use by display device developers and other service providers, the equipment and personnel required for maintenance can be covered, and maintenance work can be performed without incurring additional costs to the user. Can be done.
[0033]
As described above with respect to the prior art, a major problem in repeatedly performing display adjustment of the display device by feedback control is that adjustment takes a long time. In order to solve this problem, in the present invention, various operation state data stored in the device are used together with the luminance data. However, in the type in which the processing unit 12 is provided inside the apparatus like the display adjustment device 10 illustrated in FIG. 1, the size of the processing unit 12 is limited, and the capability is inevitably low.
[0034]
In order to quickly process a large amount of data such as operation state data and luminance data, as shown in FIGS. 4 and 5, a dedicated arithmetic processing unit 30 is installed outside the display adjustment device 10, and the data and calculation results are displayed. A system that transmits and receives between the arithmetic processing unit 30 and the display adjustment device 10 'is effective.
[0035]
Of course, the display adjustment apparatus 10 may be possessed by the user, or may be disposed in a service store or the like. As a result, even when the display adjustment is unexpectedly required while going out, the adjustment can be performed without any problem.
[0036]
Further, the display adjustment device 10 'can be connected to the arithmetic processing unit 30 via the Internet. As a result, a uniform display adjustment service can be performed at any place in the world without any trouble, so that display adjustment can be performed without any problem even at a business trip destination or a travel destination, and the device 20 is used. The data of the arithmetic processing unit 30 can be used to develop a device that takes into account regional characteristics such as the temperature and climate conditions of the place.
[0037]
Furthermore, since various kinds of data such as operation state data representing the operation state of the display device 21 of the device 20 for a predetermined period and luminance data of the display device 21 are collected in the arithmetic processing unit 30 in FIGS. 4 and 5. It is also possible to evaluate the reliability of the display device 21 using the collected data.
[0038]
The example of the embodiment of the present invention has been described above, but the present invention is not limited to this. For example, the display adjustment of the display device mounted on the device has been described so far, but the present invention can be applied to the display adjustment of the display device itself having a light emitting unit.
[0039]
[Example 1]
Hereinafter, some examples of the present invention will be described. As a first embodiment of the display adjustment procedure according to the present invention, a display adjustment device 10 having the configuration of FIG. 1 provided with a CMOS photosensor array as the light receiving unit 11 is manufactured, and a portable terminal in which an organic EL is mounted as a display device 21 The display adjustment of the device 20 was performed. The display adjustment device 10 and the mobile terminal device 20 are connected by the connection unit 13 so that the mobile terminal device 20 can be charged from the display adjustment device 10 via the charging terminal 14. In this way, by incorporating functions that are absolutely necessary for a portable terminal or the like into the display adjustment device, the user is unaware that the display device 21 is being maintained, and the user bears the cost of maintenance equipment. This makes it possible to perform maintenance of the display device without being conscious of it.
[0040]
The mobile terminal device 20 has a built-in memory 23 for storing the accumulated usage time of the display device 21, the accumulated driving current for each pixel, and the accumulated operating temperature. The integrated current for each pixel was measured by a current measurement circuit built in the display device 21 as described in JP-A-10-254410.
[0041]
The processing unit 12 in the form of a microcomputer chip in the display adjustment device 10 includes data of current-luminance characteristics, voltage-luminance characteristics, and driving time-luminance characteristics measured in advance, and initial luminance data and initial color balance data of the organic EL. Was stored in advance. Further, the processing unit 12 transfers the luminance of the display device 21 and the operation state data in the memory 23 to the processing unit 12, and calculates and calculates correction data for correcting display deterioration of the display device 21. A program for transferring the correction data to the display device drive unit (not shown) of the portable terminal 20 was written.
[0042]
The display adjustment device 10 and the portable terminal device 20 thus prepared are arranged as shown in FIG. 1, the display device 21 emits light over the entire surface, the light emission is received by the light receiving unit 11, the luminance is detected, and the program is executed. Thus, display adjustment of the display device 21 was performed, and at the same time, the mobile terminal device 20 was charged from the display adjustment device 10 using the charging terminal 14.
[0043]
The display device 21 at this time was manufactured as follows by arranging the light-receiving color light-emitting devices in two dimensions. A CMOS photosensor array and a comparison correction circuit unit as a light receiving unit on a glass substrate were made of polysilicon (pSi) and connected to each other by electrodes. Subsequently, an ITO transparent electrode, an organic EL layer, and an opposing AlLi electrode were sequentially formed by mask vapor deposition so as to separately and independently cover each light receiving portion. As the light emitting layer, the R light emitting part was Alq ₃ doped with DCJTB, the G light emitting part was Alq ₃ , and the B light emitting part was DPVBi and laminated on TPD to form a light emitting layer / hole transport layer laminated structure. The light emitting section and the comparison correction circuit section were connected to a drive circuit for controlling driving, and finally the entire apparatus was sealed with a SUS thin plate as a protective member. The size of each organic EL pixel was 200 μm × 200 μm, the photosensor light receiving part was 20 μm × 20 μm, and a 100 pixel × 100 pixel two-dimensional display array was obtained.
[0044]
Therefore, the initial color is such that the white light emission state at the time of full lighting is a luminance of 200 cd / m ² and the white color is at the position of (x, y) = (0.33, 0.33) on the CIE chromaticity diagram. In order to set the balance, the drive current value of each color light emitting unit was adjusted. Next, a program for correcting and controlling the drive current so that the color balance in the initial white light emission state and the luminance ratio of each color deviate from the initial balance is stored in the comparison and correction unit.
[0045]
Therefore, when the above program was executed and the light was continuously emitted in the fully lit state, the luminance gradually decreased but the white color change could not be felt with the naked eye. When measured with a chromaticity meter, there was no change in color balance even after 3000 hours.
[0046]
Next, when the operation of the light receiving unit and the comparison correcting unit is turned off and the display device is continuously lit in the same manner, the red color suddenly weakens after about 100 hours and the white color changes. But it was easy to confirm.
[0047]
From the above, since the luminance degradation of the R light-emitting portion is remarkable, a practical color balance cannot be maintained when the present invention is not used. However, the present invention can solve this problem, and a practical color can be solved. A light emitting device and a color display could be realized.
[0048]
[Example 2]
As a second embodiment of the present invention, a color adjusting device was two-dimensionally arranged to produce a display adjustment device 10 ′ having the configuration shown in FIG. It was produced in the same manner as in Example 1 except that two R light emitting parts were produced.
[0049]
The G light emission part, the B light emission part, and one R light emission part are driven to emit light, and the white light emission state at the time of all lighting is 200 cd / m ² , and (x, y) = (0.33) on the CIE chromaticity diagram. , 0.33), the drive current value of each color light emitting unit for setting the initial color balance was adjusted so as to be completely white. The comparison correction unit stores a program for correcting and controlling the current so that the color balance in the initial white light emission state and the luminance ratio of each color deviate from the initial balance to approach the initial state.
[0050]
When the light was continuously emitted in the fully lit state while executing the above program, the brightness gradually decreased but the white color change could not be felt with the naked eye. When measured with a chromaticity meter, no change was seen in the color balance even after 3000 hours, but the red color suddenly weakened from around 5000 hours, and the white color changes even with the naked eye. It was easy to confirm, and finally the red light emission disappeared.
[0051]
When the same measurement was performed by switching the signal supply from the R light emitting unit where the light emission disappeared to the remaining R light emitting units, practical color light emission could be confirmed again up to about 5000 hours.
[0052]
Thus, even if there is no problem in the life of the G light emitting part and the B light emitting part, since the life of the R light emitting part is remarkably short, the device life has been dominated by the R light emitting part until now. When the invention is applied, it has been found that the substantial device life can be doubled by automatically switching the light emitting section. In this embodiment, two short-lived light emitting portions that control the device life are provided. However, depending on the relationship with the light emission life of the light emitting portions of other light emission colors, the device life can be further extended by providing three or more light emitting portions. I can do it.
[0053]
[Example 3]
As a display device 21, a white illumination device having a Y light-emitting portion formed of Alq ₃ doped with rubrene was produced, and the effects of the present invention could be confirmed in the same manner as in Example 1 and Example 2.
[0054]
[Example 4]
In Example 1, Example 2, and Example 3, the same experiment was conducted using continuous grain boundary silicon or single crystal silicon wafer instead of polysilicon. As a result, Example 1, Example 2, Example 3 and Similar results could be obtained.
[0055]
【The invention's effect】
As described above, from the description of the embodiments and examples of the present invention, the present invention provides display correction for a self-luminous display device such as an organic EL, an inorganic EL, and an LED, and a device equipped with them. It can be performed in a short time and accurately at the user or store level. Moreover, the maintenance work can be performed without making the user aware of it. Further, by secondary use of the operation state data of the display device, it is possible to cover the maintenance equipment and personnel costs without burdening the user.
