Driving system of display screen and driving method thereof

A driving system for a display screen, comprising:

• a temperature detection circuit, for detecting a temperature of a display area of the display screen;
• a compensation calculation circuit, coupled to the temperature detection circuit, for calculating a display voltage compensation control signal of the temperature;
• and
• a data driving circuit, coupled to the compensation calculation circuit, for generating a display voltage signal matching the display voltage compensation control signal and transmitting to the display screen, wherein the compensation calculation circuit comprises a sequentially coupled timing control (TCON) circuit, a gamma selection circuit, and a gamma generating circuit, the timing control (TCON) circuit being coupled to the temperature detection circuit, and the gamma generating circuit being coupled to the data driving circuit;
• the temperature detection circuit comprising:
• a measurement unit, for measuring a temperature value of at least one of pixels on the display screen;
• a calculation unit, coupled to the compensation calculation circuit, for calculating an average value of the temperature of the at least one of pixels.
