Abstract:

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 Vth sensing with an error of 0.07V for ΔVth=0.5V and no error for ΔVth=-0.5V. Verified in FHD AMOLED panel further, the proposed method improves image sticking and luminance uniformity significantly.
