Problems solved by technology

In a design with high pixel density, due to the small area of ​​the pixel unit, it is difficult to lay out five signal lines laterally in the area of ​​each pixel unit. It is necessary to modify the driving circuit in the sub-pixel to reduce the need for horizontal wiring, but modify the pixel compensation The reduction of horizontal wiring in the circuit will affect the display performance of the pixel unit

Abstract

The invention discloses an organic light emitting diode display array. According to the organic light emitting diode display array, through changing the time sequence control relationship and circuit connection relationship of organic light emitting diode pixel units, organic light emitting diode sub pixels of adjacent lines can share signals of scanning lines arranged in the middle of the two. On the premise of not reducing the performances of a pixel compensation circuit, wiring of N-1 scanning lines can be reduced for N lines of sub pixel unit arrays, wiring density can be greatly reduced, and the wiring space is saved.

Description

technical field [0001] The invention relates to the field of organic light emitting diode displays, in particular to an organic light emitting diode display array. Background technique [0002] Organic light-emitting diodes (OLEDs) are widely used in lighting and display fields due to their low voltage requirements and high power-saving efficiency, fast response, light weight, thin thickness, simple structure, and low cost. [0003] figure 1 It is a schematic circuit diagram of an existing OLED display device. like figure 1 As shown, the organic light emitting diode display device 100 includes a data line controller 101, a scan line controller 102, a light-emitting trigger signal controller 103, and an organic light emitting diode display array. The organic light emitting diode display array includes a substrate and an N×M array The organic light emitting diode pixel units 104 arranged on the substrate, each organic light emitting diode pixel unit 104 includes four sub-pi...
