Abstract
The present invention provides a temperature sensing system integrated in a liquid crystal display panel and a liquid crystal display panel. The temperature sensing system includes a sensing unit (), located in a display region () of the liquid crystal display panel, and a calculation and control unit (), located outside the display region (); the sensing unit () includes a first metal conductor (A) and a second metal conductor (B) located in the display region (), and as a short circuit point exists between the two, a voltage difference generates between the two, and the voltage difference is converted into a digital signal with an analog to digital converter () after it is amplified by an operational amplifier (), and finally, the micro controller unit () processes the digital signal to obtain a temperature in the liquid crystal display panel and to determine whether the protect temperature is reached.
