Description

  In the present invention, an element number is assigned to each measurement value of a measurement value group obtained by measurement in the same measurement procedure, the element number is taken in the x-axis direction, and each measurement value is taken in the y-axis direction. The present invention relates to a measurement result display device and a measurement result display method for displaying a measurement result on display coordinates.

  As a system for testing an LCD driver, there is a system equipped with an array operation unit. The array operation unit has a function of checking the magnitude relationship between array variables. The user prepares three array variables on the array operation unit, and sets the output voltage, the upper limit determination value, and the lower limit determination value of the output pins of the LCD driver as the respective array variables. The array operation unit passes the path if the magnitude relationship between these three array variables (upper limit judgment value> output voltage> lower limit judgment value) is established in all the array elements, and fails if there is no place in any one place. Notice.

The array variable display tool displays the waveform variables of the array operation unit in a wave shape. The user can visually confirm the value of the array variable by designating the array variable. In addition, since the array variable display tool has a function for superimposing waveforms, the array variable in which the above upper limit judgment value, output voltage, and lower limit judgment value are set is displayed so that the magnitude relationship between the three array variables is large. Can be visually grasped.

  When a failure occurs in the array calculation unit, the user displays the above three array variables in an overlapping manner using the array variable display tool, and specifies the output pin of the device that output the fail value and the output gradation at that time. Move the cursor to the position of the fail data. When the cursor is moved to the fail data, the array element number of the array variable at that position is displayed. Therefore, based on the array element number, the pin that outputs the fail value and the output gradation can be calculated.

  In order to specify the pin and the output gradation from the array element number, it is usually obtained by dividing the array element number by the number of output pins. However, when there are many failure locations, it is necessary to repeat this calculation, which is a burden on the user. Furthermore, since the array operation unit can perform test determination for a plurality of gradations in a lump, in order to specify pins and output gradations for such test data, only simple division as described above is required. In this case, a complicated calculation that takes offsets into account is required.

  Hereinafter, an embodiment in which a measurement result display device according to the present invention is applied to an LCD driver test system will be described with reference to FIGS.

  FIG. 1 is a block diagram showing the configuration of the measurement result display device of this embodiment.

  As shown in FIG. 1, the measurement result display device of this embodiment measures the array element numbers of the measurement values, which are array variable data, on display coordinates in the x-axis direction and individual measurement values in the y-axis direction. A screen display device 20 for displaying the result, start number acquisition means 11 for acquiring the array element number of the display start position of any measurement value group on the display coordinates, and the measurement value group on the display coordinates Display width acquisition means 12 for acquiring the display width in the x-axis direction, cursor coordinate acquisition means 13 for acquiring the x coordinate of the cursor displayed on the display coordinates as an array element number, start number acquisition means 11, display width Based on the information acquired by the acquisition unit 12 and the cursor coordinate acquisition unit 13, the cursor position calculation unit 14 converts the array element number of the measurement value corresponding to the x coordinate of the cursor into the order in the specific measurement result group. Includes a cursor position display means 15 displays the calculated result by the cursor position calculating means 14, a.

  Next, the operation of the measurement result display device of this embodiment will be described.

  FIG. 2 is a diagram showing a display screen of the screen display device 20. FIG. 3 is a diagram showing a display screen when the display is further enlarged.

  In this LCD driver test system, each LCD driver is measured by the same measurement procedure. In this measurement procedure, the output values are measured in the order determined for all output pins while changing the gradation in the order determined, and consecutive array element numbers are attached to the measured values to obtain array variable data. It is taken in. 2 and 3, the x coordinate of the display screen corresponds to the array element number of the array variable data, and the y coordinate of the display screen corresponds to the value of the array variable data. 2 corresponds to the array variable data for one LCD driver, and in this example, all 64 gradations are measured for each output pin. Has been done. As shown in FIG. 3, at each gradation, the values of array variable data for all output pins are plotted side by side in the x-axis direction (lateral direction) of the display coordinates.

  Thus, as the data for one period of the waveform shown in FIG. 2, the measurement value 21 (FIG. 3) of the number of “the number of gradations (64) × the number of output pins” is included. Moreover, as shown in FIG. 3, the upper limit value 22 and the lower limit value 23 which show the normal range of the measured value 21 for every gradation are displayed on the display screen. The upper limit value 22 and the lower limit value 23 are captured in advance as array variable data with consecutive array element numbers, similarly to the measurement value 21, and the array element numbers of the upper limit value 22 and the lower limit value 23 are Corresponds to the array element number.

  The screen display device 20 performs screen display as shown in FIGS. 2 and 3 based on these array variable data (FIG. 1). When the upper limit 22 and the lower limit 23 are exceeded, it is determined that the output pin is defective.

  Further, as shown in FIG. 1, the cursors 41 and 42 (FIG. 2), at corresponding positions on the display screen of the screen display device 20, based on the cursor coordinate data generated in response to the user's operation on the mouse or the like. Cursors 43 and 44 (FIG. 3) are displayed. Further, the cursor coordinate acquisition means 13 acquires the coordinates of each cursor from the cursor coordinate data, and converts the x coordinate into an array element number (FIG. 1). The array element number corresponding to the x coordinate of each cursor is displayed on the display screen of the screen display device 20. For example, the array element number corresponding to the coordinates of the cursor 41 is displayed in the area 41a and the area 25 (FIG. 2), and the array element number corresponding to the coordinates of the cursor 43 is displayed in the area 43a and the area 26 (FIG. 3). .

  FIG. 4 is a diagram showing a gradation setting dialog displayed on the display screen.

  When the gradation setting dialog 3 is displayed on the display screen of the screen display device 20 and the user operates the automatic gradation determination button 31 of the gradation setting dialog 3, the start number acquisition means 11 and the display width acquisition means 12 are arranged as array variables. Based on the data (upper limit 22, lower limit 23 or measured value 21), the array element number of the gradation start point 46 (FIG. 2), the array element number of the gradation start point 47 (FIG. 3), and the gradation interval 48 ( FIG. 3) and gradation information such as the number of gradations (for example, 64) are automatically determined. The gradation start point 46 corresponds to the start point of a series of measurement procedures for measuring the output voltage while switching the gradation for one LCD driver. The gradation start point 47 corresponds to the measurement start point for each gradation. The gradation interval 48 corresponds to the interval between successive gradation start points 47.

  The automatically determined gradation information is displayed in the gradation setting dialog 3. For example, the gradation start point 46 is displayed in the area 46a as the offset value 46A (FIG. 2) from the origin in the display coordinates, the gradation interval 48 is displayed in the area 48a, and the number of gradations is displayed in the area 49. When adopting the result of automatic discrimination, these values are set as the gradation information by the user operating the setting button 32.

  When the result of the automatic determination is incorrect, the user can also directly input the array element number into the gradation setting dialog 3, and in this case, the start number acquisition means 11 and the display width acquisition means 12 are the array variable data. Instead, tone information is generated using data input by the user (FIG. 1). Similarly, when the user operates the setting button 32, these values are set as gradation information.

  When the gradation information is set, the cursor position calculation unit 14 determines the array element number corresponding to the x coordinate of the cursor obtained from the cursor coordinate acquisition unit 13 based on the gradation information, Conversion is made in the order of the measured values within the gradation. As described above, in the present embodiment, the same measurement procedure is repeatedly executed for each LCD driver. In addition, since array element numbers are consecutively assigned to each array variable, array element numbers are consumed equally for individual LCD drivers. For this reason, it can be determined which LCD driver the array element number belongs to, and what number of measurement values in the measurement value group. Further, since the same measurement procedure is executed for each LCD driver, including the order of gradation and the order of output pins, the numbers of gradations and output pins are the measured values in the measured value group for each LCD driver. The order can be determined. Therefore, based on the array element number, the gradation and the output pin number in the measurement value group for each LCD driver are uniquely specified.

  In the present embodiment, the array element number is automatically converted to the gradation at which the cursor is arranged and the output pin number within the gradation based on the gradation information. For this reason, even when the number of data is large or measurement values are accumulated in many cycles, the conversion is executed instantaneously and accurately.

  FIG. 5 is a diagram showing a display example by the cursor position display means 15. In the example of FIG. 5, the gradation calculated by the cursor position calculation unit 14 and the output pin number within the gradation are displayed in, for example, the area 51 a near the cursor 51 and the area 52 below.

  As described above, according to the measurement result display device of the present embodiment, the x coordinate of the cursor or the array element number corresponding to the x coordinate is converted into the gradation and the number of the output pin within the gradation. Since it is displayed, it is possible to grasp the defective pin of the LCD driver instantaneously and accurately just by positioning the cursor. In addition, misidentification due to manual calculation errors can be prevented.

  In the above embodiment, the x-axis is the horizontal direction, but the direction of the x-axis can be arbitrarily determined.

  As described above, the measurement corresponding to the x coordinate of the cursor displayed on the display coordinates based on the element number of the display start position of any measurement value group and the display width of the measurement value group in the x-axis direction. Since the element numbers of the values are converted into the order in the specific measurement result group, the measurement contents of the measurement results displayed on the display coordinates can be easily grasped.

  The scope of application of the present invention is not limited to the above embodiment. In the present invention, an element number is assigned to each measurement value of a measurement value group obtained by measurement in the same measurement procedure, the element number is taken in the x-axis direction, and each measurement value is taken in the y-axis direction. The present invention can be widely applied to a measurement result display device and a measurement result display method for displaying a measurement result on display coordinates.
