Embodiment Construction

[0027] As mentioned in the background section, the display panel in the prior art is prone to color shift and has the problem of high power consumption of the backlight module.

[0028] The inventor finds that the reason for the above phenomenon is specifically as follows: figure 1 As shown, it is a schematic structural diagram of a display panel in the prior art; the display panel includes a backlight module (BL) 01 and a color filter (CF) substrate 02 arranged oppositely, and a black matrix 03 is arranged on the color filter substrate 02, and the black The hollow part of the matrix 03 forms the opening of the display panel, and color filters and transparent color filters of different colors are arranged at the opening positions of the black matrix 03, so that different pixels emit different lights to form a display screen.

[0029] A display panel in the prior art is designed as follows: the backlight module 01 adopts a blue backlight, and the color film arranged in the open...

Abstract

The invention discloses a display panel and a display device. The display panel includes a plurality of pixels arranged in rows and columns, a plurality of data lines extending in the column directionand a plurality of scan lines extending at least in the row direction. The multiple pixels include first pixels, second pixels and third pixels, wherein the first pixels and the second pixels are located in the same columns and are connected with the same data lines. The first pixels include first transparent color films, the second pixels include second non-transparent color films, and the thirdpixels include third non-transparent color films. The area of each first pixel is smaller than the area of each second pixel, and the area of each third pixel is larger than the area of each second pixel. The pixel area corresponding to the transparent color films is reduced, and the pixel area corresponding to the non-transparent color films is increased, so that the color shift problem caused by the excessive amount of light emitted by the pixels corresponding to the transparent color films is avoided; and meanwhile, the pixel area corresponding to the non-transparent color films is increased so that the overall transmittance of backlight can be increased, the brightness of a backlight module is reduced, and the power consumption of the backlight module can be reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] At present, display panels are widely used in electronic devices such as mobile phones, tablet computers, and information inquiry machines in halls of public places. The main structure of the display panel may include a backlight module and a color filter substrate arranged opposite to the backlight module. Among them, the display can present color images mainly by the color filter in the color filter substrate. [0003] In the prior art, a transparent color film and a colored color film are usually arranged on the color film substrate. The pixel transmittance corresponding to the transparent color film is relatively high, and color shift is prone to occur when the display panel displays images. Moreover, due to the influence of the color film on the backlight Absorption, resulting in low transmittance...
