TFT-LCD capable of adjusting its light source

摘要

A thin film transistor liquid crystal display (TFT-LCD) capable of adjusting its light source utilizes at least one thin film transistor (TFT) disposed in a peripheral region of a bottom substrate as a photo sensor for detecting ambient illumination. Then, a light source modulator can enhance, weaken, open or close the light source of the TFT-LCD to an optimal brightness level that depends on the ambient illumination spontaneously.
