Abstract

The present invention provides an organic light emitting diode (OLED) display panel. At least one light transmissive region used for placing photosensitive elements thereon is defined in a display region of the OLED display panel. Special-shaped sub-pixels are arranged at a periphery of each of the at least one light transmissive region. Each special-shaped sub-pixel comprises at least one recess, and the at least one recess is at one side of the special-shaped sub-pixel facing a corresponding one of the at least one light transmissive region. An edge of each of the at least one recess conforms in shape to an edge of a corresponding one of the at least one light transmissive region.

Claims (26)

1. An organic light emitting diode (OLED) display panel, comprising:

a display region, a sensing region positioned in the display region;

at least one light transmissive region defined in the display region, the at least one transmissive region positioned in the sensing region; and

a plurality of sub-pixels disposed in the display region, wherein the sub-pixels comprise multiple regular-shaped sub-pixels and multiple special-shaped sub-pixels, wherein the special-shaped sub-pixels are disposed in the sensing region and at a periphery of each of the at least one light transmissive region, and wherein the sub-pixels excluding the special-shaped sub-pixels are the regular-shaped sub-pixels;

wherein each of the special-shaped sub-pixels comprises at least one recess at one side facing a corresponding one of the at least one light transmissive region, and an edge of each of the at least one recess conforms in shape to an edge of a corresponding one of the at least one light transmissive region, wherein each of the at least one light transmissive region comprises at least one curved edge protruding outwardly, and each of the special-shaped sub-pixels comprises one curved recess at one side facing a corresponding one of the at least one curved edge.

2. The OLED display panel according to claim 1 , wherein each of the at least one light transmissive region has a symmetrical shape about its center.

3. The OLED display panel according to claim 2 , wherein a shape of each of the light transmissive regions is a circular shape.

4. The OLED display panel according to claim 1 , wherein an area of each of the special-shaped sub-pixels is equal to an area of each of the regular-shaped sub-pixels of the display region.

5. The OLED display panel according to claim 1 , wherein the special-shaped sub-pixels surround the at least one light transmissive region, and the special-shaped sub-pixels are arranged along virtual horizontally extending lines and virtual perpendicularly extending lines connecting adjacent ones of the regular-shaped sub-pixels.

6. The OLED display panel according to claim 5 , wherein each of the at least one light transmissive region has a circular shape, and the special-shaped sub-pixels are arranged at respective four ends of two orthogonal diameters of each of the at least one light transmissive region.

7. The OLED display panel according to claim 6 , wherein at each of the four ends of the two orthogonal diameters is disposed one of the special-shaped sub-pixels, an arc length of one of the at least one recess of each special-shaped sub-pixel is substantially equal to one-fourth of a circumference of a corresponding one of the at least one light transmissive region.

8. The OLED display panel according to claim 6 , wherein two of the special-shaped sub-pixels are disposed at each of the four ends of the two orthogonal diameters, and an arc length of one of the at least one recess of each special-shaped sub-pixel is substantially one-twelfth of a circumference of a corresponding one of the at least one light transmissive region.

9. The OLED display panel according to claim 8 , a complementary-color sub-pixel is disposed between the two special-shaped sub-pixels at one end of the same diameter, and the complementary-color sub-pixel and the two special-shaped sub-pixels at two sides thereof are of different colors.

10. An organic light emitting diode (OLED) display panel, comprising:

a display region, a sensing region positioned in the display region;

at least one light transmissive region defined in the display region, the at least one transmissive region positioned in the sensing region; and

a plurality of sub-pixels disposed in the display region, wherein the sub-pixels comprise multiple regular-shaped sub-pixels and multiple special-shaped sub-pixels, wherein the special-shaped sub-pixels are disposed in the sensing region and at a periphery of each of the at least one light transmissive region, and wherein the sub-pixels excluding the special-shaped sub-pixels are the regular-shaped sub-pixels;

wherein each of the special-shaped sub-pixels comprises at least one recess at one side facing a corresponding one of the at least one light transmissive region, and an edge of each of the at least one recess conforms in shape to an edge of a corresponding one of the at least one light transmissive region, wherein each of the at least one light transmissive region comprises at least one curved edge, and each of the special-shaped sub-pixels comprises one curved recess at one side facing a corresponding one of the at least one curved edge.

11. The OLED display panel according to claim 10 , wherein each of the at least one light transmissive region has a symmetrical shape about its center.

12. The OLED display panel according to claim 10 , wherein a shape of each of the light transmissive regions is a circular shape.

13. The OLED display panel according to claim 10 , wherein an area of each of the special-shaped sub-pixels is equal to an area of each of the regular-shaped sub-pixels of the display region.

14. The OLED display panel according to claim 10 , wherein the special-shaped sub-pixels surround the at least one light transmissive region, and the special-shaped sub-pixels are arranged along virtual horizontally extending lines and virtual perpendicularly extending lines connecting adjacent ones of the regular-shaped sub-pixels.

15. The OLED display panel according to claim 14 , wherein each of the at least one light transmissive region has a circular shape, and the special-shaped sub-pixels are arranged at respective four ends of two orthogonal diameters of each of the at least one light transmissive region.

16. The OLED display panel according to claim 15 , wherein at each of the four ends of the two orthogonal diameters is disposed one of the special-shaped sub-pixels, an arc length of one of the at least one recess of each special-shaped sub-pixel is substantially equal to one-fourth of a circumference of a corresponding one of the at least one light transmissive region.

17. The OLED display panel according to claim 15 , wherein two of the special-shaped sub-pixels are disposed at each of the four ends of the two orthogonal diameters, and an arc length of one of the at least one recess of each special-shaped sub-pixel is substantially one-twelfth of a circumference of a corresponding one of the at least one light transmissive region.
