Driving circuit capable of making a liquid crystal display panel display an expanded picture without special signal processor

摘要

A driving circuit has a plurality of sample and hold circuits which are connected to data buses of a liquid crystal display panel. The data buses are divided into a plurality of groups. Each of the groups receives a picture signal to drive the data buses. A timing controller controls operation timing of the groups in response to a synchronizing signal and a clock signal to control each of the groups independently of one another.
