Abstract:
1. A device for eliminating the flickering of thin-film-transistor liquid-crystal-display (TFT-LCD), the device comprises: a first switch, configured between a power supply and an output end of the device; a discharge circuit, with one end connected between the first switch and the output end of the device and the other end connected to the ground; a second switch, for controlling whether the discharge circuit is grounded; a trigger signal source, for controlling the switches; wherein when the first switch is on and the second switch is off, the output end of the device is connected to the power supply and the circuit is recharged, and when the first switch is off and the second switch is on, the discharge circuit is grounded and discharged; and means for delaying opening of the second switch at lower temperatures, wherein the means is a component or circuit with negative temperature coefficient.
