Abstract: In order to solve a problem of deviation of a gamma curve of a display device due to temperature variation, the present invention provides a thermal compensation device for compensating a gamma curve of a display device. The thermal compensation device includes a thermal sensor, a storage unit, and a thermal compensation unit. The thermal sensor is used for detecting an ambient temperature inside the display device. The storage unit is used for storing a plurality of numerical data groups. The thermal compensation unit is coupled to the thermal sensor and the storage unit is used for selecting one numerical data group from the plurality of numerical data groups and transforming original image data into compensated image data with the selected numerical data group.
