Abstract

A display panel includes a pixel block, a data circuit, and a data source. The pixel block includes a first sub-pixel coupled to a first data line, and N second sub-pixels. Each second sub-pixel of the N second sub-pixels is coupled to a corresponding second data line of N second data lines. The data circuit includes N switches. Each switch of the N switches is coupled to a corresponding second sub-pixel. When N voltage levels are sequentially outputted from the data source to the first data line and the N second data lines, the N switches are disabled sequentially.

Claims (41)

1. A display panel, comprising:

a pixel block, comprising:

a first sub-pixel coupled to a first data line; and

N second sub-pixels, each second sub-pixel of the N second sub-pixels coupled to a corresponding second data line of N second data lines;

a data circuit, comprising:

N switches, each switch of the N switches coupled to a corresponding second data line for reaching a corresponding second sub-pixel, wherein N is a positive integer; and

a data source coupled to the first data line and the N switches;

wherein N voltage levels are outputted from the data source to the first sub-pixel via the first data line; and

wherein each of the N switches is enabled in sequence for forwarding a corresponding one of N voltage levels to the corresponding second sub-pixel via the corresponding second data line;

wherein each of N voltage levels passes through the first sub-pixel before reaching each of N switches.

2. The display panel of claim 1 , wherein when the N voltage levels are sequentially outputted from the data source to the first data line and the N second data lines, the N switches are enabled and then disabled sequentially.

3. The display panel of claim 1 , wherein two data circuits respectively coupled to two adjoining pixel blocks are disposed to different sides of the two adjoining pixel blocks.

4. The display panel of claim 1 , wherein the N second sub-pixels and the first sub-pixel are allocated sequentially according to a pixel sequence formed by a red sub-pixel, a green sub-pixel, and a blue sub-pixel.

5. The display panel of claim 1 , further comprising:

a gate circuit for driving a plurality of sub-pixels of at least one pixel block;

wherein the gate circuit and the data circuit are disposed to two opposite sides of the pixel block.

6. The display panel of claim 1 , wherein widths of a plurality of pixel blocks of the display panel are identical.

7. The display panel of claim 1 , wherein a width of the data circuit is smaller than or equal to a width of the pixel block.

8. The display panel of claim 1 , wherein a width of the data circuit is 1-2 times greater than a width of the pixel block.

9. The display panel of claim 1 , wherein widths of a plurality of pixel blocks of the display panel are not all the same.

10. The display panel of claim 1 , wherein the data circuit is a demultiplexer.

11. The display panel of claim 1 , wherein the first sub-pixel is blue.

12. The display panel of claim 1 , further comprising:

a gate circuit for driving a plurality of sub-pixels of at least one pixel block; and

a fan-out circuit, wherein the fan-out circuit is disposed between the data circuit and the gate circuit;

wherein the plurality of sub-pixels form a display area, the data circuit is disposed adjacent to a perimeter of the display area, and the gate circuit is further away from the perimeter of the display area.

13. The display panel of claim 1 , wherein the first data line connects the data source to each of N switches.

14. The display panel of claim 1 , wherein the data circuit is a demultiplexer.

15. A display panel, comprising:

a pixel block, comprising:

a first sub-pixel coupled to a first data line; and

N second sub-pixels, each second sub-pixel of the N second sub-pixels coupled to a corresponding second data line of N second data lines;

a data circuit, comprising:

N switches, each switch of the N switches coupled to a corresponding second data line for reaching a corresponding second sub-pixel; and

a data source coupled to the first data line and the N switches;

wherein N voltage levels are outputted from the data source to the first sub-pixel via the first data line, each of the N switches is enabled initially, and each of the N switches is disabled in sequence after forwarding a corresponding one of N voltage levels to the first data line and N data line, and N is a positive integer;

wherein each of N voltage levels passes through the first sub-pixel before reaching each of N switches.

16. The display panel of claim 15 , wherein two data circuits respectively coupled to two adjoining pixel blocks are disposed to different sides of the two adjoining pixel blocks.

17. The display panel of claim 15 , wherein the N second sub-pixels and the first sub-pixel are allocated sequentially according to a pixel sequence formed by a red sub-pixel, a green sub-pixel, and a blue sub-pixel.

18. The display panel of claim 15 , wherein widths of a plurality of pixel blocks of the display panel are identical.

19. The display panel of claim 15 , wherein a width of the data circuit is smaller than or equal to a width of the pixel block.
