Organic light‐emitting diode (OLED) displays has gradually developed into the dominant mobile display technology. But with the increasing of consumer demand on product, the high quality of display images and Fluency of refresh has become an urgent problem to be solved. The mechanism of crosstalk for OLED display device was studied, and a method to increasing the capacitance is proposed to reduce the crosstalk caused by parasitic capacitance. The method of the article is proposed to enhance its voltage stabilization effect, then to reduce the effect of parasitic capacitance.

The Simulation Model of Back Plane Circuit Vertical Crosstalk (BP‐VC) of AM‐OLED displays was established according to the experimental VC test method in this paper. The impact of the Pixel Storage capacitance (Cst) and the Parasitic Capacitance had been studied. Pixel with good simulated VC had been optimized by increasing Cst and decreasing the parasitic capacitance of gate electrode of driving TFT (N1 node) and Gate line (Cap2), thus reaching the achievement that BP‐VC decreases from 1.54% to 0.76% in 6.5 inch FHD OLED Display.
