发明名称 LIQUID CRYSTAL DISPLAY DEVICE AND METHOD FOR CONTROLLING BACK-LIGHT BRIGHTNESS
摘要 The present invention relates to a liquid crystal display and method of preventing dazzling thereof, by which human eyes can be prevented from being fatigued by the intensity of radiation in a manner of detecting APL of an LCD TV and correcting brightness of a backlight. The present invention includes an APL detecting unit detecting APL of the liquid crystal display, a control unit increasing or decreasing a brightness of a backlight uniformly in inverse proportional to the APL value detected by the APL detecting unit, the control unit increasing the brightness of the backlight according to a decrement of the APL value by limiting the brightness of the backlight to a prescribed brightness for a preset reference section, and a backlight driving unit driving the backlight by controlling the brightness of the backlight under the control of the control unit.
