摘要
Disclosed is a chip temperature control circuit of a liquid crystal display panel, comprising a chip, the temperature of the chip increasing with the increase of power consumption; a thermosensitive element positioned on the chip, the electrical characteristic of thermosensitive element changing in response to change in the temperature of the chip; an analog-to-digital converter which is electrically connected to both ends of the thermosensitive element to obtain an analog voltage signal of the thermosensitive element, the analog-to-digital converter converting the analog voltage signal into a corresponding digital voltage signal; a timing controller which is electrically connected to an output of the analog-to-digital converter and the chip respectively, the timing controller obtaining a corresponding chip temperature according to the digital voltage signal obtained and adjusting the chip to reduce power consumption when the temperature of the chip exceeds a predetermined temperature. The invention also discloses a liquid crystal display panel.
