Background
During operation of the current liquid crystal display device, each liquid crystal pixel is driven by a corresponding Thin Film Transistor (TFT) to realize high speed, high brightness and high contrast ratio for displaying information.
Since the electron mobility of the amorphous silicon thin film transistor is reduced in a low temperature environment, the driving current is reduced along with the reduction of the ambient temperature, and the turn-on voltage (Gate High Voltage, VGH) is increased along with the reduction of the ambient temperature. Therefore, when the ambient temperature is always reduced, the driving current cannot drive the thin film transistor when the starting voltage is unchanged, that is, the same starting voltage can only make the thin film transistor in a half-on state (i.e. a non-full-on state), so that the charging of the liquid crystal pixel point corresponding to the thin film transistor is incomplete, and the situation of abnormal picture of the liquid crystal display device is caused.
The prior art sets a temperature compensation circuit in a low temperature environment to drive the thin film transistor by sensing a lower temperature and providing a higher turn-on voltage through the thermistor, but the use of a higher turn-on voltage always reduces the lifetime of the thin film transistor.
The prior art has the problem that the service life of the thin film transistor is reduced due to the fact that the temperature compensation circuit increases the starting voltage.
