Abstract

We developed new circuit architecture for reducing the power consumption and chip-size of driver ICs. In this paper we describe a new drive scheme, based on the concept of time -sharing output and optimal circuit design based on color resolution. In case of 132 x 176-pixel class, we used only 8 O p-A mps for a 262-k color display.
