Abstract
A dynamic Gamma correction circuit, method thereof and a panel display apparatus are provided. The panel, display apparatus has a timing controller, a dynamic Gamma correction circuit, a display panel and a display driving circuit. The timing controller receives a first image data and then outputs a second image data and a timing control signal. The dynamic Gamma correction circuit receives and analyzes a distribution of gray levels of the first image data so as to dynamically correct and output a plurality of Gamma voltages. The display driving circuit electrically connects to the display panel, the timing controller and the dynamic Gamma correction circuit for receiving the second image data and the Gamma voltage so as to drive the display panel according to the timing control signal.
