Abstract

A display screen includes a first display area, which is provided with a first pixel unit array, and a second display area, which is provided with a second pixel unit array, wherein the pixel density of the first display area is less than that of the second display area, the first display area includes a first sub-area and a second sub-area, and the second sub-area is connected to the first sub-area and the second display area; and the display screen further includes a pixel driving unit array, which is arranged in the second sub-area, wherein each pixel driving unit respectively drives each first pixel unit, a first number of rows of pixel driving units are arranged corresponding to a second number of rows of first pixel units in a row extension direction, and the first number is greater than the second number. Also disclosed is an electronic device.

First claim

What is claimed is:

1 . A display screen, comprising:
a first display region, arranged with an array of first pixel units; and a second display region, arranged with an array of second pixel units; wherein the first display region comprises a first sub-region and a second sub-region, the second sub-region is adjacent to and connected with the first sub-region and the second display region; wherein the display screen further comprises an array of pixel driving units disposed in the second sub-region, each pixel driving unit of the array of pixel driving units is configured to drive a respective one first pixel unit of the array of first pixel units; and wherein a first number of rows of pixel driving units are arranged in a row extension direction and are corresponding to a second number of rows of first pixel units, the first number is greater than the second number.

2 . The display screen according to claim 1 , wherein a sub-pixel, which is disposed in the first display region, and another sub-pixel, which is disposed in the second display region and has a same color as the sub-pixel in the first display region, have different shapes.

3 . The display screen according to claim 1 , wherein a row extension direction of the pixel units is the same as the row extension direction of the pixel driving units.

4 . The display screen according to claim 1 , wherein the first number of rows of pixel driving units are configured to drive the corresponding second number of rows of first pixel units.

5 . The display screen according to claim 4 , wherein the first number of rows is two rows, the second number of rows is one row, and the two rows of pixel driving units are configured to drive, sequentially from row to row, the corresponding one row of first pixel units.

6 . The display screen according to claim 1 , wherein the first number of rows of pixel driving units are configured to drive the corresponding second number of rows of first pixel units successively, and a spacing between a part of the first pixel units driven by pixel driving units in one row of the first number of rows and another part of the first pixel units driven by pixel driving units in another row of the first number of rows next to the one row is a third number of columns, and the third number is determined based on the first number.

7 . The display screen according to claim 6 , wherein the first number of rows is two rows, and the second number of rows is one row, the two rows of pixel driving units are respectively configured to drive the corresponding one row of first pixel units in sequence, and a spacing between a part of first pixel units driven by the pixel driving units in a first one of the two rows and another part of first pixel units driven by the pixel driving units in the othera second one of the two rows is one column.

8 . The display screen according to claim 1 , wherein each first pixel unit of the array of first pixel units comprises a plurality of first sub-pixels, and each second pixel unit of the array of second pixel units comprises a plurality of second sub-pixels; and
for one color, a size of each of the plurality of first sub-pixels is larger than a size of each of the plurality of second sub-pixels.

9 . The display screen according to claim 1 , wherein two second sub-regions are arranged, and the two second sub-regions are located on opposite sides of the first sub-region respectively.

10 . The display screen according to claim 1 , wherein the second sub-region is configured to surround the first sub-region.

11 . The display screen according to claim 9 , wherein the first number of rows of pixel driving units corresponding to the second number of rows of first pixel units are alternately arranged in the two oppositely located second sub-regions.

12 . The display screen according to claim 1 , wherein a number of pixel driving units in the second sub-region is not less than a number of first pixel units in the first display region.

13 . The display screen according to claim 1 , wherein the array of first pixel units comprise an array of organic light emitting diode (OLED) units; and the array of pixel driving units comprises a thin film transistor.

14 . The display screen according to claim 1 , further comprising a transparent conductive material, wherein the pixel driving units in the second sub-region are connected to the first pixel units through the transparent conductive material; and the transparent conductive material is indium tin oxide and/or indium gallium zinc oxide.

15 . The display screen according to claim 1 , further comprising an array of pixel driving units disposed in the second display region, wherein distribution of the pixel driving units in the second sub-region is the same as distribution of the pixel driving units in the second display region.

16 . The display screen according to claim 15 , wherein the pixel driving units in the second display region are in one-to-one correspondence with the second pixel units in the second display region.

17 . The display screen according to claim 1 , wherein a pixel density of the first display region is less than a pixel density of the second display region.

18 . An electronic device, comprising:
a display screen and a photosensitive module; wherein the display screen comprises:
a first display region, arranged with an array of first pixel units; and
a second display region, arranged with an array of second pixel units;
wherein the first display region comprises a first sub-region and a second sub-region, the second sub-region is adjacent to and connected with the first sub-region and the second display region; wherein the display screen further comprises an array of pixel driving units disposed in the second sub-region, each pixel driving unit of the array of pixel driving units is configured to drive a respective one first pixel unit of the array of first pixel units; wherein a first number of rows of pixel driving unit are arranged in a row extension direction and are corresponding to a second number of rows of first pixel units, the first number is greater than the second number; and wherein the photosensitive module is arranged at a rear side of the display screen and corresponding to the first sub-region.
