Abstract

Embodiments of the disclosure provide a pixel structure, a method for driving the pixel structure and a display apparatus. The pixel structure comprises a matrix of multiple R sub-pixels, G sub-pixels and B sub-pixels. In each row of the sub-pixels, at most two adjacent sub-pixels constitute a square pixel unit. Each two adjacent rows of the sub-pixels are offset relative to each other by half a sub-pixel along a row direction. Each of the sub-pixels is different in color from its adjacent sub-pixels. With such a pixel structure, light is reallocated for input information based on a correspondence relationship between an actual physical position and its corresponding input information so as to emit light concentratedly at the actual physical position. For example, a white pixel may be displayed by switching on only three adjacent sub-pixels triangularly arranged at the pixel unit which displays the white to be switched on. According to the embodiments of the disclosure, the same information is displayed with fewer pixels by selectively switching on sub-pixels in a flexible manner without reducing the size of pixels, thereby increasing the output resolution for displayed images.

First claim

What is claimed is:

1 . A pixel structure comprising a matrix of multiple R sub-pixels, G sub-pixels and B sub-pixels, wherein
in each row of the sub-pixels, at most two adjacent sub-pixels constitute a square pixel unit, each two adjacent rows of the sub-pixels are offset relative to each other by half a sub-pixel along a row direction, each of the sub-pixels is different in color from its adjacent sub-pixels.

2 . The pixel structure according to claim 1 , wherein in each row of the sub-pixels,
each two sub-pixels constitute a square pixel unit and each sub-pixel has a length-width ratio of 2:1, each one and a half sub-pixels constitute a square pixel unit and each sub-pixel has a length-width ratio of 3:2, or each one sub-pixel constitutes a square pixel unit and each sub-pixel has a length-width ratio of 1:1.

3 . A display apparatus comprising a pixel structure according to claim 1 .

4 . A display apparatus comprising a pixel structure according to claim 2 .

5 . A method for driving a pixel structure according to claim 1 , the method comprising:
upon receipt of an image signal for displaying at least a white pixel, switching on three adjacent sub-pixels triangularly arranged at a pixel unit in the pixel structure which displays the white pixel.

6 . A method for driving a pixel structure according to claim 2 , the method comprising:
upon receipt of an image signal for displaying at least a white pixel, switching on three adjacent sub-pixels triangularly arranged at a pixel unit in the pixel structure which displays the white pixel.

7 . The method according to claim 5 , wherein
upon receipt of an image signal for displaying at least a row or column of white pixels, switching on three adjacent sub-pixels triangularly arranged at each of pixel units in the pixel structure which display the row or column of white pixels.

8 . The method according to claim 7 , further comprising:
switching on three adjacent sub-pixels triangularly arranged at each of one or two rows or columns of pixel units in the pixel structure which are adjacent to the pixel units which display the row or the column of white pixels.

9 . The method according to claim 7 , wherein
upon receipt of an image signal for displaying at least a pixel of a single color, switching on a sub-pixel of the same color at a pixel unit in the pixel structure which displays the pixel of the single color.

10 . The method according to claim 7 , wherein
upon receipt of an image signal for displaying at least a row or column of pixels of a single color, switching on a sub-pixel of the same color at each of pixel units in the pixel structure which display the row or column of pixels of the single color.

11 . The method according to claim 10 , further comprising:
switching on a sub-pixel of the same color at each of one or two rows or columns of pixel units in the pixel structure which are adjacent to the pixel units that display the row or the column of pixels of the single color.

12 . The method according to claim 7 , wherein
upon receipt of an image signal for displaying at least an oblique line of pixels of a single color, switching on a sub-pixel of the same color at each of pixel units in the pixel structure which display the oblique line of pixels of the single color.

13 . The method according to claim 7 , wherein
upon receipt of an image signal for displaying at least an oblique line of pixels of a single color, switching on a sub-pixel of the same color at each of one or two oblique lines of pixel units in the pixel structure which are parallel to and adjacent to the oblique line of the single color on one or both sides.

14 . The method according to claim 12 , further comprising switching on a sub-pixel of the same color at each of one or two oblique lines of pixel units in the pixel structure which are parallel to and adjacent to the oblique line of the single color on one or both sides.
