Abstract

The present application relates to a display device that is divided into a first region as a fingerprint recognition region and a second region as a display region with the first region having a first light transmittance greater than a second light transmittance of the second region. The light transmittance of the region corresponding to the fingerprint recognition module group in the display device of the present application can be increased, thereby further improving the sensitivity of the fingerprint recognition module group.

First claim

2 . The display device according to claim 1 , wherein the display device comprises a driving layer comprising first driving units and second driving units, and the light transmittance of the first driving unit is greater than the light transmittance of the second driving unit, and
the first region comprises the first driving units and the second driving units, and the second region only comprises the second driving units.

3 . The display device according to claim 1 , wherein the display device comprises a driving layer comprising first driving units and second driving units, and the light transmittance of the first driving unit is greater than the light transmittance of the second driving unit, and
the first region comprises the first driving units and the second driving units, and the second region comprises the first driving units and the second driving units.

4 . The display device according to claim 2 , wherein the number of light-blocking elements constituting the first driving units is less than the number of light-blocking elements constituting the second driving units.

5 . The display device according to claim 2 , wherein a sum of projection areas of light-blocking elements constituting the first driving units on a plane of the driving layer is smaller than the sum of the projection areas of the light-blocking elements constituting the second driving units on a plane of the driving layer.

6 . The display device according to claim 2 , wherein the first region comprises a first-unit row and a second-unit row, the first driving units are arranged in a first-unit row, and a second-unit row comprises at least the second driving units, and the first-unit row and the second-unit row are alternately arranged in the first region.

7 . The display device according to claim 6 , wherein the second-unit row further comprises at least one first driving unit.

8 . The display device according to claim 2 , wherein the first driving units and the second driving units are alternately arranged in a left and right direction and an up and down direction in the first region.

9 . The display device according to claim 2 , wherein the second driving units are arranged in a row, and the rows of the second driving units are continuously arranged and remaining positions in an array of the driving layer corresponding to the first region are occupied by the first driving units.

10 . The display device according to claim 4 , wherein a light-blocking element comprises a thin film transistor and a capacitor.

11 . The display device according to claim 3 , wherein the number of light-blocking elements constituting the first driving units is less than the number of light-blocking elements constituting the second driving units.

12 . The display device according to claim 3 , wherein a sum of projection areas of light-blocking elements constituting the first driving units on a plane of the driving layer is smaller than the sum of the projection areas of the light-blocking elements constituting the second driving units on a plane of the driving layer.

13 . The display device according to claim 3 , wherein the first driving units are arranged in a first-unit row, and the second driving units are arranged in a second-unit row, and the first-unit row and the second-unit row are alternately arranged in the first region.

14 . The display device according to claim 13 , wherein the second-unit row comprises at least one of the first driving units.

15 . The display device according to claim 4 , wherein the first driving units are arranged in a first-unit row, and the second driving units are arranged in a second-unit row, and the first-unit row and the second-unit row are alternately arranged in the first region.

16 . The display device according to claim 5 , wherein the first driving units are arranged in a first-unit row, and the second driving units are arranged in a second-unit row, and the first-unit row and the second-unit row are alternately arranged in the first region.

17 . The display device according to claim 11 , wherein the first driving units are arranged in a first-unit row, and the second driving units are arranged in a second-unit row, and the first-unit row and the second-unit row are alternately arranged in the first region.

18 . The display device according to claim 12 , wherein the first driving units are arranged in a first-unit row, and the second driving units are arranged in a second-unit row, and the first-unit row and the second-unit row are alternately arranged in the first region.

19 . The display device according to claim 3 , wherein the first driving units and the second driving units are alternately arranged in a left and right direction and an up and down direction in the first region.

20 . The display device according to claim 3 , wherein the second driving units are arranged in row, and remaining positions in an array of the driving layer corresponding to the first region are occupied by the first driving units.
