Abstract

The application discloses a display device, a temperature sensor and a temperature sensing method. The temperature sensor includes a transfer unit, the transfer unit includes at least one first transistor interconnected between the input end and the output end, the control end of each first transistor is connected to the first channel end, when the number of first transistors is more At this time, the second channel end of the previous first transistor is connected to the first channel end of the latter first transistor, wherein the threshold voltage of the first transistor changes with temperature, and when the transfer unit receives a valid input signal, the transfer unit The unit generates an output signal according to the threshold voltage of the first transistor and a valid input signal. By making a temperature sensor composed of transistors in the display device, the temperature sensor generates an output signal based on the characteristics of the transistor, replacing the temperature sensing device in the prior art, and realizing temperature detection, thus solving the problem of high cost of the display device .

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display device, a temperature sensor and a temperature sensing method. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) has now become the mainstream display technology in the market. The liquid crystal display device includes: a color filter substrate, a pixel array substrate with a thin film transistor (Thin Film Transistor, TFT) located under the color filter substrate , the liquid crystal layer sandwiched between the color filter substrate and the array substrate, the driver chip and the backlight module, etc. [0003] Because whether it is the TFT formed on the pixel array substrate or the liquid crystal molecules in the liquid crystal layer, they will show different characteristics due to the influence of the external temperature. For example, if the external temperature is lower, the electron mobility of the TFT will be...
