Voltage generator for driving a thin film transistor liquid crystal display |
摘要 |
<p>A device for turning on a thin film transistor liquid crystal display includes a first switching circuit for generating and outputting an inverse common voltage signal in response to a switching signal, a second switching circuit for generating and outputting a common voltage signal in response to an inverse switching signal and a level shift circuit for generating and outputting a potential capable of turning on a thin film transistor by using the inverse common voltage signal and the common voltage signal. The switches preferably are implemented with PMOS and NMOS transistors. This device can reduce power consumption by eliminating the analog switch, the operational amplifier and the push-pull circuit. A similar device for turning off a thin film transistor liquid display is also disclosed. <IMAGE></p> |
