摘要： A timing controller is provided. The timing controller comprises a data analyzer, a gain processor, an operator unit and an original gamma voltage generator. The present invention utilizes the data analyzer to analyze a gray level distribution of video data, and then the gain processor selects a gain value. The operator unit converts an original gamma voltage produced by the original gamma voltage generator into an actual gamma voltage according to the gain value. Therefore, the present invention adaptively adjusts the gamma voltage according to the gray level distribution of the video data for increasing display quality.

摘要： A light source driving circuit including a driving module, a plurality of first switches, a detecting unit, and a control unit is provided. The plurality of first switches is respectively coupled to corresponding light sources and these light sources are driven by the driving module. The detecting unit is coupled to the driving module to detect a working parameter of each light source and transmit the working parameter to the control unit. When the detecting unit detects some of these light sources are broken down, the control unit sequentially turns on the first switches to find out the failed light source. Moreover, the first switch coupled to the failed light source is remained on, and the driving signal is regulated according to the number of the failed light source, such that the brightness of the panel does not decrease.
