Problems solved by technology

[0003] The inventors found that in related technologies, when the OLED display panel is in the off-screen state, after the external light is reflected by the internal structure of the OLED display panel, the reflected light will be diffracted by the filter, causing color separation, which seriously affects the user's perception , thereby reducing the reliability of OLED display panels

Abstract

A display panel and a display device, wherein the display panel includes: a base and a plurality of color filters of different colors arranged on the base; the filter includes: a plurality of sub-filters arranged in an array, so that When the display panel is in the off-screen state, the light emitted from the filters of different colors mixes to form white light. The present application arranges a plurality of optical filters arranged in an array so that when the display panel is in the off-screen state, the light emitted from the filters of different colors mixes to form white light, which eliminates the color separation that occurs when the display panel is in the off-screen state phenomenon, thereby improving the reliability of the display panel.

Description

technical field [0001] This article relates to the field of display technology, and in particular to a display panel and a display device. Background technique [0002] Organic Light-Emitting Diode (English: Organic Light-Emitting Diode, referred to as OLED) display panel has many advantages such as self-illumination, ultra-thin, fast response speed, high contrast ratio, wide viewing angle, etc., and is currently a display panel that is widely concerned. A color filter on encapsulation (Color Filter on Encap, COE for short) technology is provided in the related art, that is, a color filter is packaged on the light-emitting side of an OLED display panel. Since the filter can filter light, Therefore, the amount of ambient light that enters into the OLED display panel and is reflected from the light-emitting side after being reflected by the internal structure of the OLED display panel can also be reduced. [0003] The inventors found that in related technologies, when the OLE...
