Abstract
Embodiments of the present disclosure provide a display driving circuit, a driving method thereof, a display driving system and a display apparatus. The display driver circuit comprises a processor, a storage and a grey scale voltage generator. The storage is configured to store at least two gamma curves, wherein each of the at least two gamma curves is associated with a range of temperature. The processor is configured to obtain a current environment temperature, to determine a range to which the current environment temperature belongs based on the current environment temperature; to retrieve the gamma curve associated with the range determined from the storage, and to output the retrieved gamma curve to the grey scale voltage generator.
