Problems solved by technology

However, the existing polarizers are often thicker and have lower transmittance. In order to ensure the thinner design and display quality of the OLED display panel, a thinner color filter (Color Film) is currently installed on the package of the OLED display panel. , CF) to replace the polarizer
When the color filter reflects ambient light, the black matrix (Black Matrix, BM) arranged in it will cause serious diffraction of ambient light, and even cause glare, which will affect the display quality.
[0004] It can be seen that the existing OLED displays have technical problems such as serious ambient light diffraction and poor display quality.

Abstract

The invention provides an OLED display panel, a manufacturing method thereof and a display device, and the OLED display panel comprises a substrate base plate; a plurality of light-emitting devices arranged on the substrate base plate in an array mode; and color filters arranged on the light-emitting sides of the light-emitting devices and multiplexed as polarizers, wherein each color filter comprises a shading part, a color resistor and a functional part located at the junction position of the shading part and the color resistor, the shading part is provided with an opening at the position corresponding to each light-emitting device, the functional part is arranged in the opening, the opening is covered by the color resistor, and the thickness of the functional part meets the condition of destructive interference. Therefore, the diffraction of ambient light is reduced, the glare phenomenon is improved, and the display quality is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel, a manufacturing method thereof and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) display panels have the advantages of simple structure, fast response, active light emission, low power consumption, etc., and have been widely used in display fields such as mobile phones, tablets, and televisions. [0003] The anode, cathode and various metal wiring layers in the existing OLED can reflect ambient light, and when the ambient light is strong, it is very easy to affect the self-luminescence of the OLED display panel, thereby affecting the display quality of the OLED display panel. For this reason, a polarizer is often arranged on the package of the OLED display panel to reduce the specular reflection of the OLED display panel to ambient light. However, the existing polarizers are often thicker and have lower transmittance....
