Abstract

The present invention provides an organic light emitting diode display panel and a mask plate. The organic light emitting diode display panel comprises a plurality of pixel regions commonly defined byelectrodes and organic light emitting materials, the pixel regions are arranged in a matrix mode on a plane, the sizes of the pixel regions are increased in a first direction, and the pixel regions are increased in a second direction perpendicular to the first direction. The technical problem of uneven frame display caused by the voltage drop phenomenon in the prior art is solved.

Description

technical field [0001] The present application relates to a display technology, in particular to an organic light emitting diode display panel and a mask. Background technique [0002] In the Organic Light Emitting Diode (Organic Light Emitting Diode) display panel, each pixel structure includes an organic electroluminescence (Organic Electroluminescence, EL) device, which includes an anode, a cathode, and a light-emitting layer arranged between the two to emit light. The layer is driven by an electric field between the anode and cathode, resulting in light emission through carrier injection and recombination. [0003] figure 1 A schematic diagram showing a conventional OLED display panel. Such as figure 1 As shown, the OLED display panel includes a plurality of scan lines 1 , a plurality of data lines 2 and a pixel region 3 formed by interweaving the scan lines 1 and the data lines 2 . In the prior art, the size of all pixel regions 3 is the same. Since the scan line 1...
