Abstract

The embodiment of the invention provides a display panel and a preparation method thereof. The display panel comprises a substrate, a first filter layer arranged on one side of the substrate, and a second filter layer arranged on one side, far away from the substrate, of the first filter layer. The reflectivity of the display panel to the first light is not greater than 50%; and / or the reflectivity to the second light is not greater than 10%. The display panel provided by the embodiment of the invention has relatively high reflectivity to light within the wavelength range of the light-emitting layer and relatively low reflectivity to light outside the wavelength range of the light-emitting layer. When external light enters the display panel, light within the wavelength range of the light-emitting layer is reserved in a targeted mode and reflected to the light-emitting side of the display panel so as to improve the brightness of the display panel, light outside the wavelength range of the light-emitting layer is absorbed so as to eliminate stray light interference on the light-emitting side, the contrast ratio of the display panel is improved, and the display effect is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a display panel and a manufacturing method thereof. Background technique [0002] Currently, there are usually two technical routes used in Organic Electroluminescence Display (OLED) display technology: one is to use a circular polarizer as a necessary component of an OLED touch display panel, and the other is to use a color filter (Color Filter, CF) replaces the polarizer (COE, Color Filter On Encapsulation) in OLED. [0003] In the first technical route, the main function of the circular polarizer is to reduce the reflectivity when external light is incident on the OLED surface, thereby improving contrast and readability under ambient light. Circular polarizers are generally attached to the packaging cover of the display panel, but the thickness of the overall module is relatively large. If it is applied to a flexible display de...
