Abstract

The invention provides an OLED display panel. The OLED display panel comprises an array substrate, a light-emitting device layer located on the array substrate, an anti-color separation layer located on the light-emitting device layer, a packaging layer located on the anti-color separation layer and a cover plate layer located on the packaging layer; and the anti-color separation layer comprises a color filter layer aligned with the light emitting device layer and a black matrix located in a gap of the color filter layer, and materials of the color filter layer comprise a color resistance material and high polymer materials with anisotropic characteristics doped and in the color resistance material. Due to the fact that the high polymer materials with the anisotropic characteristics have body density differences in different directions, the high polymer materials with the anisotropic characteristics are distributed in the color resistance materials, so that light phases in different positions and different directions of the color filter layer are changed, the interference effect is weakened, the color separation phenomenon is relieved, and the color gamut of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, relates to an OLED display panel. Background technique [0002] Full-color OLED displays have the advantages of wide display color gamut, high brightness, large viewing angle, low power consumption, and long life. The pixel units of full-color display screens currently on the market are composed of three primary colors of red, green and blue. According to the principle of three primary colors, various colors can be produced by controlling the red, green, and blue monochromatic gray levels of the sub-pixel unit, thereby displaying a color picture. [0003] In order to prevent the reflection of the OLED display screen, a layer of polarizer needs to be arranged on the light output side. The polarizer adopts the principle of polarized light, which can effectively reduce the reflection intensity of external ambient light on the screen, but the transmittance of the polar...
