摘要： A driving apparatus includes a timing controller, a gate driver, and a pulse width controller. The timing controller generates a gate output enable signal having a width which is used for defining on-voltage widths of gate driving signals. The gate driver sequentially outputs the gate driving signals corresponds to a plurality of gate lines. The gate driver is controlled to prevent overlapping of the gate driving signals. The pulse width controller includes a signal generator and a converter. The signal generator receives two of the gate driving signals from two adjacent gate lines, compares the two gate driving signals, and generates a detection signal that detects an overlapping area of the two gate driving signals. The converter converts the detection signal to a pulse width control signal and feeds the pulse width control signal back to the timing controller. The timing controller receives the pulse width control signal and adjusts the width of the gate output enable signal.

摘要： An LCD driving scaler capable of reducing electromagnetic interference employs a spread spectrum phase locked loop (PLL) in which a multi-phase voltage controlled oscillator oscillates and outputs a scaler pixel clock signal and a plurality of oscillation signals of different phases. A spread spectrum processor counts clock periods of a reference pixel clock signal when a horizontal synchronization signal having an adjusted frame rate is activated, and sequentially outputs the plurality of oscillation signals in response to a decoding signal. The plurality of oscillation signals are output to a main divider, which generates the main divider signal by dividing the frequencies of the plurality of oscillation signals. A main divider signal is input into a phase frequency detector, which detects a phase difference between the predivider signal and the main divider signal and outputs the phase difference signal so that the frequency of the scaler pixel clock signal repeatedly varies.
