Abstract:
1. A liquid crystal display module comprising a gate driver and a liquid crystal display panel having a plurality of pixel units, characterized in that: the liquid crystal display (LCD) module further comprises a transistor mounted on the LCD panel, a first error amplifier, an analog to digital converter, and a voltage regulator; a voltage difference between a gate and a source of the transistor varies with temperature; the first error amplifier having two input terminal electrically connected to the gate and the source of the transistor respectively, is used for outputting an amplified value of the voltage difference between the gate and the source of the transistor; the analog to digital converter is used for receiving the amplified value of the voltage difference and for outputting a corresponding binary signal, the corresponding binary signal being the temperature sensing signal; the voltage regulator is used for adjusting scan voltage according to the temperature sensing signal; the gate driver outputs a scan signal with the adjusted scan voltage to the plurality of pixel units.
