Abstract

A flat panel display and an image correction circuit and method thereof are provided. The image correction circuit mainly includes a digital to analog conversion unit and a data processing unit. The digital to analog conversion unit includes a temperature sensor and a gamma voltage generator. The gamma voltage generator is adopted for generating a plurality of gamma voltages, and the temperature sensor is electrically connected to the gamma voltage generator and adopted for sensing the working temperature of the gamma voltage generator. The data processing unit is coupled to the digital to analog conversion unit. When the working temperature of the gamma voltage generator changes to higher (or lower) than the room temperature, the data processing unit selects and outputs applicable digital data to the digital to analog conversion unit. Therefore, the digital to analog conversion unit outputs a predetermined gamma voltage at room temperature according to the digital data.
