ABSTRACT:
A liquid crystal display device is provided to reduce the edge-blurred influence of the liquid crystal response in accord with temperature dependency, comprising a temperature detector in an inverter circuit detecting the temperature of a liquid crystal display panel and outputting a temperature signal of the liquid crystal; a phase synchronous signal generator outputting the on/off timing signal of each fluorescent lamp in each luminescent region according to the vertical synchronizing signal of a display control device and the temperature signal from the temperature detector; a lamp drive controller in the inverter circuit determining to turn on/off the fluorescent lamp of each luminescent region in the backlight of the liquid crystal display panel with the timing signal. The turn-on signal of each fluorescent lamp is generated and subsequently delayed by the inverter circuit according to the liquid crystal response in accord with the temperature dependency in each luminescent region.
