摘要:
An impulsively driven liquid crystal display includes a display panel displaying an image in response to a gate signal and a data signal, a panel driving circuit providing the gate signal and the data signal to the display panel using an image signal and a control signal, a backlight unit including a plurality of light sources that blink at once to provide a light to the display panel, and a backlight control circuit. The backlight control circuit automatically detects an existence of text information from a received image signal, and if the text is detected to be present, adjusts the blinking timing of the light sources to correspond with the area on the display panel where the text will be displayed, the adjustment being a function of a liquid crystal response delay time of liquid crystals used in the display panel.
