  • Organic light-emitting diode display panel, manufacturing method thereof, and organic light-emitting diode display device
    Patent number: 11289674
    Abstract: An organic light-emitting diode (OLED) display panel and a manufacturing method thereof are provided. The OLED display panel includes an array substrate and a cathode structure. The cathode structure includes a metal film layer. The metal film layer includes a first metal film layer and a second metal film layer. The first metal film layer is positioned within the first active area and the second metal film layer is positioned within the second active area. Different regions of the metal film layer in the cathode structure are adjusted to different thicknesses, so that different regions have different light transmittances, which is beneficial to increase screen-to-body ratio.
    Type: Grant
