Liquid crystal panel driving circuit for display stabilization

摘要

Disclosed is a liquid crystal panel driving circuit of display stabilization, including: a plurality of output buffers buffering data voltage and supplying or cutting off the buffered data voltage to or from each of the plurality of data lines; an output MUX switch receiving outputs from two adjacent output buffers of the plurality of output buffers and transferring one of the two outputs to the plurality of data lines; a garbage switch connecting each of the plurality of data lines to a ground terminal; and a power on sensor or a power off sensor generating a power on or off reset signal in response to a turn on/off of a power supply voltage, wherein the output MUX switch is turned-off and the charge share switch and the garbage switch are turned-on, in response to the power on reset signal or the power off reset signal.
