Abstract

Demand for high quality images in mobile phones has set a new standard for displays in such portable devices. Active matrix liquid crystal displays (LCDs) are replacing the passive matrix LCDs in these applications. One of the reasons is the lack of simple techniques for displaying a large number of gray shades. Our goal was to develop new addressing techniques to fill this void and it has been achieved without increasing the hardware complexity of the drive electronics. Various techniques that are capable of displaying a large number of gray shades and a technique to reduce the power dissipation in the drive electronics are presented. Salient features of these techniques that were developed in our laboratory are discussed.
