Memory reduction method of luminance compensation algorithm for mobile AMOLED display applications

A memory reduction method of luminance compensation algorithm using luminance sensor is proposed for high resolution mobile active matrix organic light emitting diode (AMOLED) display applications. The proposed method can be applied to AMOLED panels which have poor luminance uniformity even though compensation pixel circuit is used. Measurement results show that the deviation of luminance error is reduced from 18.1% to 3.8% when the proposed algorithm is applied to 5.3-inch AMOLED panel using threshold voltage compensation pixel structure.
