[AMD7-1 (Invited)] Driving Methods for Improving Image Quality in LTPS and LTPO-based AMOLED Displays
Active-matrix organic light-emitting diode (AMOLED), Driving method, Ultra-low luminance, Variable refresh rate (VRR), Image quality enhancement
In AMOLED displays, image quality degradation due to imprecise gray scale control in ultra-low luminance and difficult compensation of switching and driving transistors in variable-refresh-rate becomes a severe issue. In this work, we investigated the primary causes of the image deterioration and proposed various methodological solutions and driving schemes.
