Real-Time Threshold Voltage and Mobility Compensation for Large-Size AMOLED Displays

摘要

A new real-time compensation method of threshold voltage (Vth) and mobility (μ) for large size AMOLED display named ‘linear charging sensing (LCS)’ is proposed in this paper. This compensation method can accomplish the Vth and μ sensing within tens or hundreds microseconds which can realize the sensing for all the pixels of FHD (1920×1080) AMOLED display within one frame time. By simulation analysis, LCS compensation method is found to have high accuracy for V
