Description

technical field [0001] The invention relates to the technical field of displays, in particular to an organic light emitting diode display panel. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) displays are technically divided into passive PMOLED (Passive matrix OLED) and active AMOLED (Active matrix OLED). Taking AMOLED as an example, its core technology includes Thin Film Transistor (TFT) devices and pixel drive circuits, OLED full-color technology and packaging. It can also be divided into bottom-emitting AMOLED and top-emitting AMOLED, as well as double-sided emission. [0003] Among them, the OLED device of top-emitting AMOLED is between the transparent electrode and the opaque electrode. The opaque electrode is fabricated together with the pixel driving circuit, while the transparent electrode is located on the other side of the OLED device. The transparent electrode is made of a metal material with a thickness less than ...
