    Abstract: A timing controller and an anti-interference method thereof are provided. The timing controller includes a timing control circuit. The timing control circuit provides an input signal for controlling a source driver. When at least one of the timing control circuit and the source driver detects that an interference event occurs to the input signal, the timing control circuit is configured to adjust a frequency of a data signal or a clock signal from a normal operation frequency to at least one anti-interference frequency. The timing control signal is further configured to provide at least one of the data signal and the clock signal to the source driver.

    Abstract: A liquid crystal display and a gate driver thereof are disclosed. The gate driver comprises a first output unit, a second output unit, a first counter, a second counter and a multiplex unit. The first counter counts a clock to control the first output unit to output odd gate driving signals according to a first start signal and a polarity signal. The second counter counts the clock to control the second output unit to output even gate driving signals according to a second start signal and the polarity signal. The multiplex unit selectively outputs the polarity signal to the first counter or the second counter.

    Abstract: The invention provides a display panel driving apparatus and a driving method thereof. The display panel driving apparatus includes a source driver circuit and a timing controller circuit. The source driver circuit loads data to data lines of the display panel in load data periods. The timing controller circuit controls the source driver circuit for dynamically configuring a time length of one of the load data periods according to whether charge sharing occurs. When a charge sharing operation is not performed on at least two of the data lines in the load data period, the load data period has a first time length. When the charge sharing operation is performed on at least two of the data lines in the load data period, the load data period has a second time length longer than the first time length.
