The display panel 100 of the first embodiment of the present application includes a transparent display region 10. The transparent display region 10 includes a pixel region 11 and a plurality of light transmission regions 12.
The pixel area 11 comprises a first pixel sub-area 11a arranged along the first direction X and a second pixel sub-area 11b arranged along the second direction Y. The first pixel sub-area 11a and the second pixel sub-area 11b intersect with each other to define a plurality of light-transmitting areas 12.

In the present first embodiment, the display panel 100 has a display area. Wherein the display area comprises a transparent display area 10. The transparent display area 10 of the display panel 100 corresponds to an area where external electronic devices are disposed.

For example, when the electronic device is a camera, the transparent display area 10 is not displayed and is in a transparent state when the electronic device works, and is used for light penetration; the transparent display area 10 is used to display a picture when the electronic device is not operating.
In addition, since the pixel region 11 and the light-transmitting region 12 have circumvented each other, the operation of the electronic device and the display of the transparent display region do not operationally conflict with each other. That is, when the transparent display area 10 is in an operating state, the electronic device may also be in an operating state. For example, when the electronic device is a sensor, the sensing array of the sensor may be disposed corresponding to the light-transmitting region 12, so as to realize that the pixel region 11 of the transparent display region 10 and the sensor are simultaneously in an operating state.
In some embodiments, the display regions of the display panel may also be all provided as transparent display regions.
In the first embodiment, each driving circuit 112 correspondingly drives one sub-pixel 111, the sub-pixels 111 and the driving circuits 112 are arranged in an overlapping manner, that is, the orthographic projection of the sub-pixels 111 on the substrate covers the driving circuits 112, therefore, the O L ED sub-pixels 111 of the first embodiment fully utilizes the opaque area of the grid-line arrangement of the driving circuits 112, the pixel aperture area is increased, and the O L ED aperture ratio is improved.
In the present first embodiment, the driver circuit 112 includes a scan line 1121, a data line 1122, and a thin film transistor 1123. The scanning line 1121 is disposed at the first pixel sub-region 11 a. A data line 1122 and a thin film transistor 1123 are disposed in the second pixel sub-area 11 b.
In the first embodiment, the pixel region 11 further includes a signal trace 113. The signal trace 113 is located below the sub-pixel 111. The sub-pixels 111 are disposed to overlap the signal traces 113. That is, the signal trace 113 is disposed in the first pixel sub-area 11a and/or the second pixel sub-area 11b, and the orthogonal projection of the sub-pixel 111 on the substrate covers the signal trace 113. Based on the above structure, the sub-pixel 111 covers the driving circuit 112 and the signal trace 113 simultaneously in the orthographic projection of the substrate.
Specifically, the signal trace 113 includes a VDD trace 1131. The VDD routing 1131 is disposed in the second pixel sub-area 11 b. The VDD routing 1131 and the data line 1122 are disposed in the same layer and in the same direction.
Therefore, the sub-pixels 111 of the first pixel sub-area 11a are arranged to overlap on the scanning line 1121. The sub-pixels 111 of the second pixel sub-area 11b are disposed on the data line 1122, the thin film transistor 1123 and the VDD routing 1131 in an overlapping manner.
In addition, the signal traces 113 may further include a clock signal trace (labeled in the figure), and the clock signal trace is disposed in the first pixel sub-area 11 a. The sub-pixels 111 of the first pixel sub-area 11a are thus arranged overlapping the scanning line 1121 and the clock signal trace.
Referring to fig. 2 and 3, in detail, the sub-pixel 111 includes a first sub-pixel 1111, a second sub-pixel 1112, and a third sub-pixel 1113. The first and second subpixels 1111 and 1112 are alternately disposed in the second pixel sub-area 11b along the second direction Y. The third sub-pixels 1113 are arranged in the first pixel sub-area 11a along the first direction X, and two adjacent third sub-pixels 1113 are arranged by one second pixel sub-area 11 b.
And, the first sub-pixel 1111 and the second sub-pixel 1112 are alternately arranged to form the column sub-pixel 111 a. The third sub-pixels 1113 are arranged at intervals to form the line sub-pixels 111 b. The data line 1122, the thin film transistor 1123 and the VDD routing 1131 are arranged extending along the second direction Y to form the column top circuit structure 112 a. The scan lines 1121 are arranged extending in the first direction X to form a line top circuit structure 112 b.
The column-item sub-pixels 111a are disposed overlapping the column-item circuit structure 112 a. The row-item sub-pixels 111b are disposed to overlap the row-item circuit structure 112 b. It should be noted that the driving circuits 112 corresponding to all the sub-pixels 111 are disposed in the second sub-pixel area 11 b.
In addition, the pixel arrangement of the first sub-pixel 1111, the second sub-pixel 1112 and the third sub-pixel 113 in an alternating arrangement enhances the display effect.
In the first embodiment, since the column item circuit structure 112a includes the data line 1122, the thin film transistor 1123 and the VDD routing 1131, and the row item circuit structure 112b includes only the scan line 1121, the column item circuit structure 112a requires a large layout area. Therefore, in order to utilize the areas of the driving circuit 112 and the signal trace 113 to the maximum, the widths of the first sub-pixel 1111 and the second sub-pixel 1112 are designed to be larger than the width of the third sub-pixel 1113. And the width of the third sub-pixel 1113 is reduced and the length of the third sub-pixel 1113 is lengthened, so that the third sub-pixel 1113 utilizes the maximum area of the scanning line 1121, thereby increasing the area of the light-transmitting region 12 and achieving the effect of improving the light transmittance.
The first sub-pixel 1111, the second sub-pixel 1112, and the third sub-pixel 1113 are all rectangular.
Further, the width of each of the first sub-pixel 1111 and the second sub-pixel 1112 is greater than the width of the third sub-pixel 1113. The lengths of the first and second sub-pixels 111 and 1112 can be reduced to arrange more first and second sub-pixels 1111 and 1112 on the column items, increasing the density of the sub-pixels.
In the first embodiment, the first sub-pixel 1111 is a red sub-pixel. The second subpixel 1112 is a blue subpixel. The third subpixel 1113 is a green subpixel. The second subpixel 1112 has an area larger than the first subpixel 1111 and the third subpixel 1113. With this arrangement, the uniformity of light emission of the entire sub-pixel 111 is improved.
In order to improve the uniformity of the light emission of the transparent display region 10, the areas of the first sub-pixel 1111, the second sub-pixel 1112 and the third sub-pixel 1113 may be adjusted, in the first embodiment, the area of the first sub-pixel 1111 is smaller than the area of the third sub-pixel 1113, and the area of the third sub-pixel 1113 is smaller than the area of the second sub-pixel 1112.
In the present first embodiment, the peripheral side of the light-transmitting region 12 includes a first side 121, a second side 122, a third side 123, and a fourth side 124. The first side 121 and the third side 123 are oppositely arranged and located at the first pixel sub-area 11 a. The second side 122 and the fourth side 124 are oppositely disposed and located in the second pixel sub-area 11 b.
Wherein, the first side 121 and the third side 123 are both provided with a third sub-pixel 1113. The second side 122 and the fourth side 124 are each provided with a first sub-pixel 1111 and a second sub-pixel 1112.
Specifically, the arrangement order of the first sub-pixel 1111 and the second sub-pixel 1112 located at the second side 122 is the same as the arrangement order of the first sub-pixel 1111 and the second sub-pixel 1112 located at the fourth side 124.
In addition, the distance from the first sub-pixel 1111 to the second sub-pixel 1112 and the distance from the second sub-pixel 1112 to the third sub-pixel 1113 are both larger than 10 microns and smaller than 40 microns, and if the distance is too large, the aperture ratio of the O L ED pixel is too small, and if the distance is too small, light mixing is easy.
The preparation process in this first example is:
providing a substrate, wherein the substrate comprises a transparent display area 10, the transparent display area 10 is divided into a pixel area 11 and a light-transmitting area 12, and the pixel area 11 comprises a first pixel sub-area 11a and a second pixel sub-area 11 b;
forming a scan line 1121 of the driving circuit 112 on the first pixel sub-area 11a, and forming a data line 1122 of the driving circuit 112, a thin film transistor 1123 and a VDD trace 1131 of the signal trace 113 on the second pixel sub-area 11 b;

So that the sub-pixels 111 are disposed to overlap the driving circuit 112.
