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. The display panel comprises an array substrate and a color film substrate arranged opposite; wherein the array substrate includes a plurality of organic light emitting diodes; and the color film substrate includes a filter layer, a black matrix and a plurality of dimming units; wherein the plurality of dimming units are located on the side of the black matrix deviating from or near the array substrate; the black matrix comprises a plurality of shading units; and the dimming unit overlaps with the corresponding shading unit in the direction perpendicular to the display panel. By setting the dimming units, the range of light emission can be reduced, and the emission of the emergent light that should be blocked from the display panel is greatly reduced, and the color deviation of the display panel can be reduced or avoided; meanwhile, it is not required to increase the thickness of the display panel to improve the display performance of the display panel, which is conducive to lightening 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.
