A first gate driving signal falls from a high level to a first level at the signal falling edge. A second gate driving signal falls from the high level to a second level at the signal falling edge. When the parasitic capacitance of a first pixel is larger than that of a second pixel, the first level is lower than the second level; when the parasitic capacitance of the first pixel is substantially the same as that of the second pixel, the first level is the same as the second level; when the parasitic capacitance of the first pixel is smaller than that of the second pixel, the first level is higher than the second level.

Abstract: A polarity-reversible dimming controller having function of switching light source has a power supply module and a dimming control module. The dimming control module receives an external PWM dimming signal to control a feedback signal of the power supply module so as to dim or power on/off an LED lamp. The dimming control module has an output current switching circuit, a switch control circuit and a dimming control circuit. The output current switching circuit performs a PWM control over a current outputted from the power supply module by using the external PWM dimming signal to maintain chromacity of the LED lamp as a constant. The switch control circuit turns off the PWM controller to enter a standby mode for saving power once the PWM dimming signal exceeds a threshold value. As a full-wave rectification is performed on the PWM dimming signal, the polarity match issue upon assembling can be disregarded.
