(Knowledge on which this disclosure was based)
First, before explaining the transmissive display according to the embodiment, the findings underlying the present disclosure will be described using the display according to the reference example.

FIG. 1 is a layout diagram showing a configuration of a display 110 according to a reference example.

In the display 110, a pixel array 115 including a plurality of pixels 114 is formed in the display area 111a of the substrate 111. Further, in the peripheral region 112a located below the display region 111a, the first data driver 118a, the gate driver 116, and the second data driver 118b are arranged side by side in the left-right direction in this order.

The first data driver 118a supplies data to the pixels 114 in the upper half of the pixel array 115 via a row wiring that passes through the left side of the display area 111a and reaches each row of the pixels 114 in the upper half of the pixel array 115. ..

The gate driver 116 supplies scanning signals to all the pixels 114 of the pixel array 115 via the column wiring that reaches each row of the pixels 114 in the pixel array 115 through the central region in the left-right direction of the display area 111a. ..

The second data driver 118b supplies data to the pixels in the lower half of the pixel array 115 via a row wiring that passes through the right side of the display area 111a to each row of the pixels 114 in the lower half of the pixel array 115.

By supplying data and scanning signals from these three drivers (first data driver 118a, gate driver 116, and second data driver 118b), the pixels 114 of the pixel array 115 emit light and an image is displayed. ..

However, in the display 110 according to the reference example having such a configuration, three drivers (first data driver 118a, gate driver 116, and second data driver 118b) are provided in the peripheral area 112a located below the display area 111a. Since it is necessary to arrange the displays 110 side by side in the left-right direction, it is difficult to narrow the width of the display 110 to reduce the size.

Therefore, the present inventors have found that, for example, the following configuration is advantageous for miniaturization of the display 110. That is, instead of arranging the three drivers (first data driver 118a, gate driver 116, and second data driver 118b) in the left-right direction in the peripheral area 112a located below the display area 111a, the maximum in the left-right direction is Only two drivers (eg, first data driver and gate driver) are placed in. Then, the remaining driver (for example, the second data driver) is arranged in a position vertically aligned with other drivers (for example, the first data driver and the gate driver), that is, in a peripheral region located above the display area 111a. I decided.

As a result, since only a maximum of two drivers are arranged in the left-right direction in the peripheral area located above and below the display area 111a, the width of the display 110 can be narrowed to reduce the size.

Hereinafter, the details of the transmissive display according to the embodiment will be described.

The pixel 14 is a pixel circuit including a light emitting element, and is, for example, a pixel circuit including a light emitting element composed of an inorganic EL (Electroluminescence) as a light emitting layer and an ITO or the like as a transparent electrode.

Each of the plurality of row wirings 17 is a wiring pattern for connecting the pixels 14 in each row and the first driver 16 in the pixel array 15. Each of the plurality of row wirings 19a is a wiring pattern that connects the pixels 14 of each row and the second driver 18a in the lower half of the pixel array 15. Each of the plurality of row wirings 19b is a wiring pattern that connects the pixels 14 of each row and the second driver 18b in the upper half of the pixel array 15. The plurality of column wirings 17 and the plurality of row wirings 19a and 19b are composed of wiring patterns of transparent electrodes such as ITO.

The first driver 16 is provided in a peripheral region (here, a first region 12a located below the display region 11a) located on the periphery of the display region 11a, and is a pixel in each row of the plurality of pixels 14. It is an IC that supplies one of the data and the scanning signal to the 14 via the plurality of row wirings 17, and is, for example, a gate driver that supplies the scanning signal via the row wirings 17. The first region 12a may be a part of the substrate 11 or a part of another circuit board such as a flexible substrate connected to the substrate 11.

The second driver 18a, which is one of the plurality of second drivers, is provided in the peripheral region (here, the first region 12a), and is provided via the row wiring 19a for the pixel 14 of each row of the plurality of pixels 14. It is an IC that supplies the other of the data and the scanning signal, and is, for example, a data driver that supplies data to the lower half of the pixels of the pixel array 15.

The second driver 18b, which is one of the plurality of second drivers, is provided in a peripheral region (here, a second region 12b located above the display area 11a) located on the peripheral edge of the display area 11a. An IC that supplies the other of the data and the scanning signal to the pixels 14 in each row of the plurality of pixels 14 via the row wiring 19b. For example, data that supplies data to the upper half pixels of the pixel array 15. It is a driver. The second region 12b may be a part of the substrate 11 or a part of another circuit board such as a flexible substrate connected to the substrate 11.

The second driver 18a and the second driver 18b are connected by a connection wiring 21. The connection wiring 21 is a wiring for transmitting data or a scanning signal, for example, a wiring for transmitting data to be output by the second driver 18b from the second driver 18a to the second driver 18b. The connection wiring 21 is also a wiring that electrically connects the first region 12a and the second region 12b.

The main body circuit unit 13 is a circuit unit including a controller for controlling the first driver 16 and the second drivers 18a and 18b, a power supply circuit, a processor, each input / output circuit, and the like. For example, a flexible substrate connected to the substrate 11. Etc. are mounted on another circuit board. The main body circuit unit 13 is not an essential component of the transmissive display 10. The main body circuit unit 13 may be connected to the substrate 11 after being manufactured separately from the transmissive display 10.

As described above, in the transmissive display 10 according to the present embodiment, the first driver 16 and the second driver 18a are one of the two horizontal sides of the display area 11a in the peripheral area (here, the lower side). ) Is arranged in the first region 12a on the peripheral side (here, lower side), while the second driver 18b is the other (here, the upper side) of the two horizontal sides of the display area 11a in the peripheral region. ) Is arranged in the second region 12b on the peripheral side (here, above).

As a result, the second driver 18b is arranged in the second region 12b of the peripheral region, which is different from the first region 12a in which the first driver 16 and the second driver 18a are arranged. Therefore, in the first region 12a of the peripheral region, not three drivers are arranged as in the conventional case, but only two drivers (first driver 16 and second driver 18a) are arranged, so that the transparent type The width of the display 10 is narrowed.

Further, the second driver 18a is arranged adjacent to the first driver 16 in the row direction. The second driver 18b is arranged in the second region 12b at a position facing the second driver 18a arranged in the first region 12a (here, the region on the right side).

As a result, the second driver 18b is arranged at a position of the second region 12b facing the second driver 18a arranged in the first region 12a, so that the pixels come out of the two second drivers 18a and 18b. All the wirings to the array 15 pass only on the right side of the display area 11a or only on the left side (here, only on the right side). Therefore, the wiring coming out of the two second drivers 18a and 18b runs on the same side of the display area 11a, and the width of the transmissive display 10 is narrowed.

The wiring 22a formed on the front surface of the substrate 11 and the wiring 22b formed on the back surface of the substrate 11 are grade-separated in a plan view of the substrate 11. As a result, the distance from the first driver 16 to the pixel array 15 is shortened, and as a result, the area of the flat area occupied by the wiring is reduced, and the transmissive display 10 can be miniaturized.

In the example shown in FIG. 4, double-sided wiring is used for the column wiring 17, but instead of or in addition to this, double-sided wiring may be used for the row wirings 19a and 19b. As a result, the distance from the second drivers 18a and 18b to the pixel array 15 is shortened, and as a result, the area of the flat area occupied by the wiring is reduced, and the transmissive display 10 can be miniaturized.

[1-4. Application example of transmissive display]
FIG. 5 is a diagram showing an application example of the transmissive display 10 according to the present embodiment. Here, an example is shown in which the transmissive display 10 is used as a display device of a mobile information terminal 27 such as a smartphone.
