P‐15.18: An introduction to Research of Improving Crosstalk (H) by Optimizing Parasitic Capacitance

With the gradual development of OLED display, the industry's requirements for display quality are getting higher and higher. Among them, crosstalk (H) is an important indicator to evaluate display quality. In research, crosstalk (H) has been greatly improved by adjusting the parasitic capacitance between driving transistor gate and scan signal (Cs2_vg). The results show that the crosstalk (H) value of Low Temperature Polycrystalline Oxide (LTPO) products can be reduced from 1.72% to 1.11% at 120Hz refresh frequency, also does not worsen other display effects after all optical inspection.
