摘要:
A display apparatus includes: a display panel; a gate driver that provides, to a plurality of scanning lines, scanning pulse signals for controlling pixel switches to be ON in a selection period corresponding to a pulse width thereof; a data driver that provides gradation voltage signals to a plurality of data lines; and a display controller that provides a modulated clock signal having a frequency that changes at a predetermined rate in one frame period. The gate driver sequentially provides the scanning pulse signals each having a pulse width reflecting to a clock cycle of the modulated clock signal in a predetermined order corresponding to distances from the data driver to the plurality of scanning lines. The data driver provides the gradation voltage signals in the order of providing the scanning pulse signals for every data period corresponding to the clock cycle of the modulated clock signal.
