Pixel-level data-line multiplexing for low-cost/high-resolution AMLCDs

Abstract

We propose a novel data-line multiplexing technique for low-cost/high-resolution active-matrix liquid-crystal displays (AMLCDs). This scheme reduces the number of data lines and driver chips required by one-half without enormous multiplexing circuits. Another advantage of applying this technique is the reduction in power consumption. We demonstrated the technical feasibility of this method with application prototypes up to 15-in. SXGA+ (1400 × 1050 pixels) AMLCDs with amorphous-silicon (a-Si) thin-film-transistor (TFT) technology. In this paper, we provide an explanation of the addressing mechanism in detail and clarify the feasibility with further technical discussion.
