Patent ID: 8405592

Claim:
A liquid crystal display system, receiving an input signal and comprising: a display panel, having a plurality of display cells and for displaying images specified by the input signal, wherein each of the display cells is controlled by a switching signal; a column decoder for controlling the displaying status of the display panel; and a row decoder, having a driving apparatus for converting the input signal into an analog driving signal, and sending the analog driving signal to the display panel so as to make the display panel display images specified by the input signal, wherein the driving apparatus comprises: a driving circuit for receiving the input signal and converting the input signal into the analog driving signal; and a control switch, electrically coupled with the driving circuit for receiving a control signal, wherein the control signal is used for controlling on or off of the control switch so as to control the spike current generated when turning on the control switch; and wherein the control signal gently increases by a rate having a constant slope during a first period and a second period, the analog driving signal gently increases during the first period and gently decreases during the second period, and an initial time point of the second period substantially starts at a falling edge of the switching signal.
