Abstract:
1. A panel display apparatus, comprising: a timing controller, for receiving an input image data, so as to obtain a current frame data, a previous frame data and a timing control signal; a display panel, for displaying images corresponding to the previous frame data and the current frame data; a dynamic Gamma correction circuit, for providing a plurality of uncorrected Gamma voltages during the display panel displays the image corresponding to the previous frame data, and further for analyzing a distribution of all of gray levels of the previous frame data so as to provide a plurality of corrected Gamma voltages during the display panel displays the image corresponding to the current frame data; a scan-line driver, electrically connected to the timing controller and the display panel, for generating a plurality of driving signals according to the timing control signal so as to sequentially drive a plurality of scan lines of the display panel; and a data-line driver, electrically connected to the timing controller, the display panel and the dynamic Gamma correction circuit, for receiving the uncorrected or corrected Gamma voltages, the previous or the current frame data and the timing control signal, and for locking the previous frame data according to the timing control signal, and selecting and outputting the uncorrected Gamma voltages corresponding to all of the gray levels of the locked previous frame data, so as to drive a plurality of data lines of the display panel and thus making the display panel display the image corresponding to the previous frame data, and further for locking the current frame data according to the timing control signal, and selecting and outputting the corrected Gamma voltages corresponding to all of gray levels of the locked current frame data, so as to drive the plurality of data lines of the display panel and thus making the display panel display the image corresponding to the current frame data, wherein the uncorrected Gamma voltages are corresponding to a first Gamma curve; the corrected Gamma voltages are corresponding to a second Gamma curve: and the first and the second Gamma curves are different.
