Problems solved by technology

However, this design method has the following problems: Assuming that the filter has three different colors, such as red, green and blue, the light emitted by the pixel may emit light from the corresponding filter of other surrounding pixels when passing through the filter. , for example, green light may pass through the blue filter, or red light may pass through the green filter, causing color shift of the display panel and affecting the performance of the display panel

Abstract

The invention discloses a display panel and a display device, comprising: an array substrate and a color filter substrate arranged oppositely; the array substrate includes a plurality of organic light-emitting diodes; the color filter substrate includes a filter layer, a black matrix, and a plurality of dimming units; Wherein, a plurality of dimming units are located on the side of the black matrix away from or close to the array substrate; the black matrix includes a plurality of light-shielding units; in a direction perpendicular to the display panel, the dimming units overlap with correspondingly arranged light-shielding units. By setting the dimming unit, the range of light emission can be narrowed, the emitted light that should be blocked is greatly reduced from the display panel, and the color shift of the display panel is reduced or avoided. At the same time, it is not necessary to increase the thickness of the display panel to improve the display. The display performance of the panel is conducive to thinning the display panel and improving the display quality of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] A display panel provided by the prior art does not use a polarizer when filtering light, but uses a filter and a black matrix to replace the polarizer. After the light from the external environment passes through the filter, only light of a specific wavelength can pass through, which plays a role The role of filtering. However, this design method has the following problems: Assuming that the filter has three different colors, such as red, green and blue, the light emitted by the pixel may emit light from the corresponding filter of other surrounding pixels when passing through the filter. For example, green light may pass through the blue filter, or red light may pass through the green filter, causing color shift of the display panel and affecting the performance of the display panel.
