Classification: CPC G | IPC G

Claim 1:
2. The automatic gamma adjustment system with environmental adaptability according to claim 1, wherein the layering control processor comprises a memory storage unit provided for the layering control processor to use the gamma control parameter to calculate and obtain the second YUV signals and buffer the second YUV signals into the memory storage unit, or to use the gamma control parameter to look up in a table to obtain the second YUV signals stored in the memory storage unit; wherein, memory of the memory storage unit and memory of the display device have a first gamma parameter conversion table and a second gamma parameter conversion table respectively, provided for the layering control processor to look up the second YUV signals from the first gamma parameter conversion table and the second gamma parameter conversion table, such that the memory storage unit still provides multi-selective gamma groups when situated in low memory storage capacity; the layering control processor comprises a temperature protection unit and a maximum brightness conversion unit, the temperature protection unit is electrically coupled to the display screen for receiving a current working temperature fed back by the display screen, and driving the maximum brightness conversion unit to adjust the maximum brightness current value if the current working temperature obtained is determined to be not falling within a safe interval value; and the layering control processor further converts the second YUV signals into a plurality of RGB signals.
