Abstract:
1. A liquid crystal display (LCD) panel, comprising: a plurality of scan lines; a plurality of data lines, said scan lines and said data lines being arranged in a matrix thereby defining a plurality of pixels; a scan driver driving said scan lines; a data driver driving said data lines, said data driver and said scan driver configured to drive said pixels; a controller connected to said scan driver and said data driver; and a common electrode; wherein said LCD panel defines a plurality of first detecting areas and a second detecting area, the second detecting area is located in a center portion of said LCD panel and the first detecting areas are located in portions of said LCD panel other than the center portion, and each of the first detecting areas and the second detecting area comprises a photo sensor; and when a reference voltage is applied to said common electrode through said controller, said photo sensors detect a minimum value of flicker levels of the first detecting areas and a flicker level of the second detecting area, and said controller compares the minimum value of flicker levels of the first detecting areas with the flicker level of the second detecting area, and when the minimum value of flicker levels of the first detecting areas is unequal to the flicker level of the second detecting area, said controller adjusts the reference voltage applied to said common electrode until a current detected minimum value of flicker levels of the first detecting areas becomes substantially equal to a current flicker level of the second detecting area.
