  • Patent number: 10930892
    Abstract: An organic light-emitting diode (OLED) display panel and a method of manufacturing the same are disclosed. The OLED display panel includes a phase-compensated liquid crystal layer and a linear polarizer disposed on an organic light-emitting device layer. The phase-compensated liquid crystal layer is disposed between the organic light-emitting device layer and the linear polarizer. Polarized light is generated after external light passes through a linear polarizer and the phase-compensated liquid crystal layer and is reflected to go through again the phase-compensated liquid crystal layer in a direction perpendicular to a polarization direction of the linear polarizer. By providing a liquid crystal layer to achieve compensation for phase difference, the present application can overcome a problem of visual interference and glare effects brought about by the display panel due to external light.
