Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0033] As mentioned in the background section, figure 1 In the RGBW display panel shown, although the blue sub-pixels are replaced with white sub-pixels in some repeating units, which improves the display brightness of the display panel, but because the part of the repeating units display white sub-pixels, they can only light up The red sub-pixel and the green sub-pixel, at this time, the light emitted by the red sub-pixel and the green sub-pixel will be mixed into yellow light, so that when some repeating units i...

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel includes: a pixel array, the pixel array includes a plurality of first repeating units arranged in an array; the first repeating unit includes a first color sub-pixel, a second color sub-pixel and a white sub-pixel, and the first repeating unit includes a first color sub-pixel, a second color sub-pixel and a white sub-pixel The light emitted by the sub-pixels of one color and the sub-pixels of the second color can be mixed to form white light. In the display panel and the display device provided by the embodiments of the present invention, the sub-pixels of the first color and the sub-pixels of the second color are arranged in repeating units including white sub-pixels, and the light emitted by the sub-pixels of the first color and the sub-pixels of the second color It can be mixed to form white light, which solves the problem of yellowish picture in the existing RGBW display panel, and can effectively improve the display brightness of the display panel at the same time.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display panel and a display device. Background technique [0002] With the development of display technology, users have higher and higher requirements on the quality of images displayed by display devices. [0003] Conventional display screens usually use red green blue (RGB) pixels to form the smallest repeating unit, and form full-color through color matching. However, the luminance of the display screen using RGB pixels is relatively low. In order to increase the luminance of the display screen, in the prior art, white sub-pixels are added to the RGB pixels to increase the luminance of the display screen through the white sub-pixels. figure 1 It is a schematic diagram of pixel arrangement of an RGBW display panel in the prior art, refer to figure 1 , in the existing red green blue white (RGBW) display, white sub-pixels are used to replace the blue sub-pix...
