Title: OLED DISPLAY PANEL PIXEL STRUCTURE AND MANUFACTURING PROCESS THEREFOR
Abstract:
Provided are an OLED display panel pixel structure and a manufacturing process therefor, the pixel structure comprising a pixel region (120), pixel unit anode conductive layers (140) and a cathode conductive layer (180), the pixel region (120) comprising multiple sequentially adjacent sub-pixel regions (121), at least two adjacent sub-pixel regions (121) forming a sub-pixel region group (122), and at least two sub-pixel regions (121) of a sub-pixel region group (122) being integrally arranged; the anode conductive layers (140) are disposed in sub-pixel regions (121), each anode conductive layer (140) being separated one from another; the cathode conductive layer (180) is electrically connected to the anode conductive layers (140), and is used to control a pixel unit (130); a pixel unit (130) comprises multiple sub-pixels (134), the pixel unit (130) is disposed in the pixel region (120), each sub-pixel (134) is individually disposed in a sub-pixel region (121), and sub-pixels (134) disposed in a sub-pixel region group (122) are integrally arranged, and have an identical color; a pixel unit (130) comprises a hole injection layer, an emissive layer and an electron injection layer.
