Claim 5:
6. The automatic gamma adjustment system with environmental adaptability according to claim 5, 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 corresponding second YUV signals which are buffered to the memory storage unit, or use the gamma control parameter to look up in a table to obtain the second YUV signals which are stored into the memory storage unit; memory of the memory storage unit and memory of the display device comprise a first gamma parameter conversion table and a second gamma parameter conversion table respectively, which are 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 when the memory storage unit is situated in a low memory storage capacity status, the memory storage unit still provides multi-selective gamma groups; 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 to receive a current working temperature fed back by the display screen, and drives the maximum brightness conversion unit to adjust the maximum brightness current value when determining and obtaining the current working temperature which does not fall within a safe interval value; and the layering control processor converts the second YUV signals into a plurality of RGB signals.
