Abstract

The invention provides a display panel. The display panel comprises a display module, an optical transparent adhesive layer located on the display module and a protective cover plate located on the optical transparent adhesive layer. Wherein scattering particles are arranged in the optical transparent adhesive layer, the light transmittance of the optical transparent adhesive layer is greater than or equal to 90%, and the haze of the optical transparent adhesive layer is greater than or equal to 15%. When external light rays are refracted into the optical transparent adhesive tape from the protective cover plate, the light rays are in contact with the surfaces of different scattering particles and are reflected back at different angles, the light rays reflected at different angles do not form periodic arrangement in a spatial structure, the phenomenon of color separation is avoided, and meanwhile, due to shielding of the scattering particles, the color separation effect is improved. And part of light rays entering the display module are reduced, so that the normal display effect of the display panel is ensured.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel. Background technique [0002] OLED display panels have become the focus of research and application in the field of organic optoelectronic displays due to their good luminous brightness, high luminous efficiency, wide viewing angle range, and self-luminescence. [0003] In order to block the ambient light reflection of the screen, the OLED display panel is provided with a layer of circular polarizer (POL) on the light-emitting side of the panel. The principle of polarized light is used to effectively reduce the reflected light of external ambient light on the screen, but the circular polarizer is used. The transmittance is reduced, and the brightness is lost by 50%. After the external light passes through the protective cover, polarizer, optically transparent adhesive layer and display module, reflected light will be generated between each film laye...
