CHIP TEMPERATURE CONTROL CIRCUIT OF LIQUID CRYSTAL DISPLAY PANEL AND LIQUID CRYSTAL DISPLAY PANEL

摘要

A liquid crystal display panel and a chip (110) temperature control circuit of liquid crystal display panel, said chip temperature control circuit comprising: a chip (110), the temperature of which increasing as power consumption increases; a heat-sensitive element, which is located on the chip (110) and changes electrical characteristics thereof according to the change of temperature of the chip (110); an analog-to-digital converter (121), which is electrically connected to both ends of the heat-sensitive element to acquire an analog voltage signal of the heat-sensitive element, and the analog-to-digital converter (121) converting the acquired analog voltage signal into a corresponding digital voltage signal; a timing controller (130), which is electrically connected to an output end of the analog-to-digital converter (121) and the chip (110) respectively, the timing controller (130) acquiring a corresponding temperature of the chip (110) according to the acquired digital voltage signal, and the timing controller (130) adjusting, when the temperature of the chip (110) exceeds a predetermined temperature, the chip (110) to reduce power consumption; The invention has the advantage of improving the service life of liquid crystal display panels.
