Problems solved by technology

[0002] Nowadays, when LCD is designed in the display area, in order to ensure the uniformity of the front brightness and chromaticity in the display panel, it is usually necessary to keep the aperture ratio of each RGB pixel consistent. Fluctuations, resulting in uneven chromaticity within the panel
[0003] Moreover, because the light guide plate in the backlight module is made of PC material, due to the characteristics of the PC material, the color temperature difference between the side of the light source and the opposite side of the backlight module gradually expands. The color temperature of the backlight module changes uniformly, and when the color temperature of the backlight module varies greatly, it will cause the color temperature in the panel to be inconsistent

Embodiment Construction

[0027] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0028] The present invention aims at the technical problem of non-uniform chromaticity in the panel caused by the process fluctuation and the material characteristics of the light guide plate in the existing display panel, and this embodiment can solve the defect.

[0029] The display panel is provided with a backlight module (not shown in the figure) on the light inci...

Abstract

The invention provides a display panel and a display device. A backlight module is arranged at a light-in side of the display panel; an LED light source is arranged at one side of the backlight module, the display panel comprises a first pixel region close to the LED light source, a third pixel region far away from the LED light source, and a second pixel region for connecting the first pixel region and the third pixel region; an open rate of the sub-pixel of at least one color in the first pixel region is less than that of the other sub-pixel, and the open rate of the sub-pixel of at least one color in the third pixel region is greater than other sub-pixel, thereby reducing the color temperature difference of the first pixel region and the third pixel region of the display panel. Correspondingly, the invention further provides a display device including the display panel. Compared with the display panel of the prior art, the display panel provided by the invention has low color temperature difference.

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] Nowadays, when LCD is designed in the display area, in order to ensure the uniformity of the front brightness and chromaticity in the display panel, it is usually necessary to keep the aperture ratio of each RGB pixel consistent. Fluctuations, resulting in uneven chromaticity within the panel. [0003] Moreover, because the light guide plate in the backlight module is made of PC material, due to the characteristics of the PC material, the color temperature difference between the side of the light source and the opposite side of the backlight module gradually expands. The color temperature of the backlight module changes uniformly, and when the color temperature of the backlight module varies greatly, it will cause the color temperature in the panel to be inconsistent. [0004] Therefore, a display pane...
