Abstract

In this paper, a digital driving technique for generating binary driving signals to display a digital video on an active-matrix organic light-emitting diode (AMOLED) panel is proposed. The ideal spatial and temporal noise characteristics of the driving signal for an AMOLED panel to display high-quality video are first suggested. Based on the suggested characteristics, a digital driving technique is proposed to generate the driving signals for an AMOLED panel. Simulation results show that the proposed driving technique can generate driving signals having the desired spatial and temporal noise characteristics and, accordingly, allows an AMOLED panel to display video of better quality than other conventional driving techniques in terms of various measures.
