摘要： A display apparatus includes a display panel comprising a pixel which is connected to a gate line and a data line, a gate driver configured to generate a gate signal having a gate-on voltage and a gate-off voltage and to provide the gate line with the gate signal, and a gate controller configured to generate a clock signal having a duty ratio and to provide the gate driver with the clock signal, where a mean amplitude of the clock signal in a vertical blanking period of a frame cycle is smaller than the mean amplitude of the clock signal in an active period of the frame cycle.

摘要： A display device includes a display panel which includes pixels arranged in a matrix form and a controller which receives a first image signal corresponding to a first active period of a first frame, outputs a first final output signal corresponding to a first conversion active period of the first frame, and drives the display panel based on the first final image signal. The controller includes a timing changing unit which receives the first image signal and changes a first image signal pixel size corresponding to the first image signal to a panel pixel size corresponding to the display panel to generate the first output signal, and a frequency changing unit which receives the first output signal from the timing changing unit and reduces a frame frequency of the first output signal based on the first image signal to output the first final output signal.

摘要： A display device includes a display panel which includes a plurality of gate lines and a plurality of pixels, where each of the pixels is connected to a corresponding gate line among the gate lines, and a gate driving circuit which includes a stage that applies a gate signal to at least one of the gate lines. The gate signal includes a high period in which the gate signal has a high voltage and a low period in which the gate signal has a low voltage having a level less than a level of the high voltage, and the low period includes a falling period in which the low voltage falls to a second level from a first level which is greater than the second level.
