The utility model provides a pixel structure.

In the embodiment of the present invention, as shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6, fig. 7, fig. 8, fig. 9 and fig. 10, the pixel structure includes a plurality of first pixel units 100 and a plurality of second pixel units 200 arranged in an array, wherein each first pixel unit 100 includes a three-primary-color pixel group 110 and a fourth sub-pixel 120, and the three-primary-color pixel group 110 includes a first sub-pixel 111, a second sub-pixel 112 and a third sub-pixel 113; the first sub-pixel 111, the second sub-pixel 112, the third sub-pixel 113, and the fourth sub-pixel 120 are arranged in a row or column direction; each second pixel unit 200 includes a three primary color pixel group 110 and a fifth sub-pixel 210, and the first sub-pixel 111, the second sub-pixel 112, the third sub-pixel 113 and the fifth sub-pixel 210 are arranged in a row or column direction; the fourth sub-pixel 120 and the fifth sub-pixel 210 are each a white sub-pixel and a yellow (Y) sub-pixel.

The first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113 are a red sub-pixel, a green sub-pixel and a blue sub-pixel, respectively, and the colors of the first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113 are different from each other. The first pixel unit 100 includes the three primary color pixel group 110 and the fourth sub-pixel 120, the second pixel unit 200 includes the three primary color pixel group 110 and the fifth sub-pixel 210, and the fourth sub-pixel 120 and the fifth sub-pixel 210 are a white sub-pixel and a yellow sub-pixel, that is, when the fourth sub-pixel 120 is a white sub-pixel, since the light transmittance of the white sub-pixel is greater than the light transmittance of the red sub-pixel, the green sub-pixel and the blue sub-pixel, the light transmittance of the entire pixel structure can be improved, the brightness of the entire display screen can be improved, and in order to prevent the brightness of the display screen from being too high, the fifth sub-pixel 210 is a yellow sub-pixel, which increases the types of the original sub-pixels, so that the chromaticity of the display screen is wider. Similarly, when the fourth sub-pixel 120 is a yellow sub-pixel, the fifth sub-pixel 210 is a white sub-pixel.

In practical applications, the arrangement of the first pixel unit 100 and the second pixel unit 200 may be determined according to practical situations, as long as the fourth sub-pixel 120 and the fifth sub-pixel 210 are ensured to be simultaneously located in the whole pixel structure. For example, 8 pixel units are provided in one area, the number of the first pixel units 100 may be equal to that of the second pixel units 200, that is, the number of the fourth sub-pixels 120 is equal to that of the fifth sub-pixels 210, and W: Y is 4:4, so that while the white sub-pixels improve the luminance of the display, the yellow sub-pixels can improve the chromaticity of the display, and at this time, the number of the white sub-pixels is equal to that of the yellow sub-pixels, so that the display can be more uniform. Of course, the number of the first pixel units 100 and the number of the second pixel units 200 may not be equal, for example, if the user likes the picture with a little higher brightness and the picture with a little lower saturation, the number of the white sub-pixels may be set to be greater than the number of the yellow sub-pixels, for example, W: Y is 7:1, 6:2, 5: 3; if the user likes the picture with higher saturation, the number of yellow sub-pixels may be set to be greater than the number of white sub-pixels, for example, W: Y is 1:7, 2:6, 3: 5.

The sub-pixels in the first pixel unit 100 and the second pixel unit 200 are arranged in a row or column direction, and the arrangement order of the sub-pixels can be determined according to the actual situation, for example, if the fourth sub-pixel 120 is a white sub-pixel and the fifth sub-pixel 210 is a yellow sub-pixel, the first pixel unit 100 can be: RGBW, RGWB, RWGB, WRGB, GBRW …, the second pixel cell 200 may be: RGBY, RGYB, RYGB, YRGB, and GBRY … are similar, the fourth subpixel 120 is a yellow subpixel, and the fifth subpixel 210 has a variable arrangement order of the subpixels. The arrangement order of the sub-pixels in the first pixel unit 100 and the second sub-pixel unit 200 is various, and the arrangement order of the sub-pixels in the pixel structure formed by combining the first pixel unit 100 and the second pixel unit 200 is also various, so that the chromaticity of the display screen of the pixel structure is wider.

The utility model discloses technical scheme arranges through a plurality of first pixel unit 100 and a plurality of second pixel unit 200 arrays, first pixel unit 100 includes three primary color pixel group 110 and fourth subpixel 120, second pixel unit 200 includes three primary color pixel group 110 and fifth subpixel 210, fourth subpixel 120 and fifth subpixel 210 each other are white subpixel and yellow subpixel, when having realized utilizing white subpixel to improve display frame luminance, utilize yellow subpixel to improve display frame's colourity.

Further, referring to fig. 3 to 8, in order to make the display image more uniform, the first pixel unit 100 and the second pixel unit 200 are disposed adjacent to each other. When the fourth sub-pixel 120 is a white sub-pixel, the first pixel unit 100 increases the brightness of the display screen, and at this time, in order to prevent the display screen near the first pixel unit 100 from being whitened, the second pixel unit 200 having a yellow sub-pixel is disposed adjacent to the first pixel unit 100 to increase the chromaticity of the display screen in the region. Taking 8 pixel units in one area as an example, to ensure that the first pixel unit 100 is adjacent to the second pixel unit 200, the number of the first pixel unit 100 is substantially equal to that of the second pixel unit 200, that is, 4:4, at this time, each two adjacent pixel units in the pixel structure include a white sub-pixel and a yellow sub-pixel, so that the brightness and the chromaticity of the display picture are both improved.
