(Knowledge that became the basis of this disclosure)
First, before describing the transmissive display according to the embodiment, the knowledge that is the basis of 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 111 a of the substrate 111. In the peripheral area 112a located below the display area 111a, the first data driver 118a, the gate driver 116, and the second data driver 118b are arranged in this order in the left-right direction.

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

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

  The second data driver 118b supplies data to the pixels in the lower half of the pixel array 115 via the row wiring that passes through the right side of the display area 111a and reaches 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 (a first data driver 118a, a gate driver 116, and a second data driver 118b) are provided in the peripheral area 112a located below the display area 111a. Since it is necessary to arrange them side by side in the left-right direction, it is difficult to reduce 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 downsizing the display 110. That is, three drivers (the first data driver 118a, the gate driver 116, and the second data driver 118b) are not arranged in the left-right direction in the peripheral area 112a located below the display area 111a. Only two drivers (for example, the first data driver and the gate driver) are arranged. Then, the remaining driver (for example, the second data driver) is arranged in a position aligned with the other drivers (for example, the first data driver and the gate driver) in the vertical direction, that is, in the peripheral region located above the display region 111a. It was decided.

  As a result, only two drivers at the maximum are arranged in the left and right direction in the peripheral area located above and below the display area 111a, so that the width of the display 110 can be reduced and the size can be reduced.

  The details of the transmissive display according to the embodiment will be described below.

The first region 12a may be a partial region in the substrate 11 or a partial region in 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 connected to the pixels 14 in each row of the plurality of pixels 14 via the row wiring 19a. For example, a data driver that supplies data to the lower half of the pixel array 15.

  The second driver 18b, which is another one of the plurality of second drivers, is provided in a peripheral region located in the periphery of the display region 11a (here, the second region 12b positioned above the display region 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 of the pixel array 15 It is a driver. The second region 12b may be a partial region in the substrate 11 or a partial region in 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 that transmits data or a scanning signal. For example, the connection wiring 21 is a wiring that transmits 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.

For example, a flexible substrate connected to the substrate 11 And mounted on another circuit board. The main body circuit unit 13 is not an essential component for the transmissive display 10. The main body circuit unit 13 may be manufactured separately from the transmissive display 10 and then connected to the substrate 11.

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

  Thereby, the 2nd driver 18b is arranged in the 2nd field 12b different from the 1st field 12a where the 1st driver 16 and the 2nd driver 18a are arranged among the peripheral fields. Therefore, not the three drivers are arranged in the first area 12a in the peripheral area, but only two drivers (the first driver 16 and the second driver 18a) are arranged as in the related art. The width of the display 10 is narrowed.

  The second driver 18a is disposed adjacent to the first driver 16 in the row direction. And the 2nd driver 18b is arrange | positioned in the 2nd area | region 12b in the position (here right area | region) facing the 2nd driver 18a arrange | positioned at the 1st area | region 12a.

  As a result, the second driver 18b is disposed at a position facing the second driver 18a disposed in the first region 12a in the second region 12b. Therefore, the second driver 18b exits from the two second drivers 18a and 18b and is a pixel. All of the wirings leading to the array 15 pass only on the right side of the display area 11a or only on the left side (here, only the right side). Accordingly, the wirings extending from the two second drivers 18a and 18b run on the same side of the display area 11a, and the lateral width of the transmissive display 10 is narrowed.

[1-2. Connection wiring details]
FIG. 3 is a cross-sectional view for explaining the details of the connection wiring 21 shown in FIG. Here, in the case where the bezel 20 is mounted on the transmissive display 10 shown in FIG. 2, a schematic cross-sectional view when the transmissive display 10 is cut along a plane passing through line III-III in FIG. In this schematic cross-sectional view, the column wiring 17 and the row wiring 19a formed on the substrate 11 are not shown, and only the substrate 11, the bezel 20, and the connection wiring 21 are illustrated.

  As shown in FIG. 3, in the transmissive display 10 according to the present embodiment, the connection wiring 21 that connects the two second drivers 18 a and 18 b arranged in two upper and lower regions in plan view is provided on the substrate. It passes through a space covered with a bezel 20 that covers the sides of 11. More specifically, the two connection wirings 21 are wiring patterns formed at the right end and the left end of the surface of the substrate 11, respectively, and pass through the space covered with the bezel 20. The surface of the substrate 11 refers to the surface of the substrate 11 on which the pixel array 15 is formed.

  Thereby, since the connection wiring 21 that connects the two second drivers 18a and 18b arranged in two upper and lower regions in plan view passes through the space covered by the bezel 20, in plan view of the substrate 11, The region through which the connection wiring 21 passes and the region covered with the bezel 20 can be overlapped. Therefore, the lateral width of the transmissive display 10 can be narrowed and a frame can be formed compared to a display in which a region through which the connection wiring 21 passes and a region covered with the bezel 20 are provided separately.

  In the transmissive display 10 according to the present embodiment, the two second drivers 18 a and 18 b are connected by the two connection wires 21, but are connected by one or three or more connection wires 21.

FIG. 4A is a diagram illustrating an example of double-sided wiring applied to the substrate 11. 4B is a cross-sectional view of the substrate 11 when the substrate is cut along a plane passing through the cutting line IVB-IVB shown in FIG.

  In the example shown in FIG. 4A, the column wiring 17 in FIG. 2 includes a wiring 22 a formed on the front surface of the substrate 11 and a wiring 22 b formed on the back surface of the substrate 11. The wiring 22 a formed on the front surface of the substrate 11 and the wiring 22 b formed on the back surface of the substrate 11 intersect three-dimensionally in plan view of the substrate 11. As a result, the distance from the first driver 16 to the pixel array 15 is shortened. As a result, the area of the planar area occupied by the wiring is reduced, and the transmissive display 10 can be downsized.

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

[1-4. Application example of transmissive display]
FIG. 5 is a diagram illustrating 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 portable information terminal 27 such as a smartphone.

[1-5. effect]
As described above, the transmissive display 10 according to the present embodiment includes a transmissive substrate 11 and a pixel array including a plurality of pixels 14 provided in a rectangular display area 11a on the substrate 11 and arranged in a matrix. 15, a plurality of column wirings 17 provided corresponding to each column in the plurality of pixels 14, a plurality of row wirings 19 a and 19 b provided corresponding to each row in the plurality of pixels 14, and a display area 11 a A first driver 16 that is provided in a peripheral region located at the peripheral edge and supplies one of data and scanning signals to the pixels 14 in each column of the plurality of pixels 14 via the plurality of column wirings 17; A plurality of second drivers 18a and 18b that are provided in the region and supply 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 wirings 19a and 19b. . The display region 11a is surrounded by two vertical sides extending in parallel to the columns of the plurality of pixels 14 and two horizontal sides extending in parallel to the rows of the plurality of pixels 14, and the first driver 16 includes the peripheral region. Among these, one of the two horizontal sides is disposed in the first region 12a on the peripheral side, and one of the plurality of second drivers (second driver 18a) is disposed in the first region 12a. Another one of the second drivers (second driver 18b) is arranged in the second region 12b on the peripheral side of the other side of the two lateral sides in the peripheral region.

  Thereby, the 2nd driver 18b is arranged in the 2nd field 12b different from the 1st field 12a where the 1st driver 16 and the 2nd driver 18a are arranged among the peripheral fields. Therefore, not the three drivers are arranged in the first area 12a in the peripheral area, but only two drivers (the first driver 16 and the second driver 18a) are arranged as in the related art. The width of the display 10 is narrowed.

  The second driver 18a is disposed adjacent to the first driver 16 in the row direction, and the second driver 18b is opposed to the second driver 18a disposed in the first region 12a in the second region 12b. It is arranged at the position to do.

  As a result, the second driver 18b is disposed at a position facing the second driver 18a disposed in the first region 12a in the second region 12b. Therefore, the second driver 18b exits from the two second drivers 18a and 18b and is a pixel. All the wirings leading to the array 15 pass only on the right side or the left side of the display area 11a. Accordingly, the wirings extending from the two second drivers 18a and 18b run on the same side of the display area 11a, and the lateral width of the transmissive display 10 is narrowed.

  In addition, the transmissive display 10 includes a connection wiring 21 that connects the second driver 18 a and the second driver 18 b, and the connection wiring 21 passes through a space covered with a bezel 20 that covers the side of the substrate 11.

  As a result, the connection wiring 21 that connects the two second drivers 18a and 18b arranged separately in the upper and lower two regions passes through the space covered by the bezel 20, and thus the connection wiring 21 in a plan view of the substrate 11 The region through which the region passes and the region covered with the bezel 20 can be overlapped. Therefore, the lateral width of the transmissive display 10 can be narrowed and a frame can be formed compared to a display in which a region through which the connection wiring 21 passes and a region covered with the bezel 20 are provided separately.

  At least one of the column wiring 17 and the row wirings 19 a and 19 b includes a wiring 22 a formed on the front surface of the substrate 11 and a wiring 22 b formed on the back surface of the substrate 11.

  As a result, not only the wiring 22a formed on the front surface of the substrate 11 but also the wiring 22b formed on the back surface of the substrate 11 can be used for the wiring output from the first driver 16 or the wirings output from the second drivers 18a and 18b. Therefore, the wiring 22a on the front surface of the substrate 11 and the wiring 22b on the back surface of the substrate 11 can be three-dimensionally crossed. Therefore, the area of the planar area occupied by the wiring can be reduced, and the transmissive display 10 can be downsized.
