Description

technical field [0001] The invention relates to the field of display technology, in particular to a passive matrix organic light emitting diode array substrate, a manufacturing method thereof, a display device and a mask plate. Background technique [0002] Organic Light-Emitting Diode (OLED) display is thin, light, wide viewing angle, active luminescence, continuously adjustable luminous color, low cost, fast response, low energy consumption, low driving voltage, and low operating temperature. With the advantages of wide range, simple production process, high luminous efficiency and flexible display, it has been listed as a promising next-generation display technology. [0003] According to different driving methods, OLED can be divided into two types: passive matrix organic light emitting diode (Passive Matrix OLED, PMOLED for short) and active matrix organic light emitting diode (Active Matrix OLED, AMOLED for short). Among them, PMOLED forms a matrix with cathodes and a...
