Abstract: A display apparatus includes a gate driving control circuit, a gate driver and a display panel. The gate driving control circuit generates N gate clock signals and N inversion gate clock signals based on N gate clock control signals, phases of which partially overlap with each other. Each inversion gate clock signals has an opposite phase to a respective gate clock signal. The gate driver generates gate signals based on the N gate clock signals or the N inversion gate clock signals and applies the gate signals to gate lines. The display panel includes pixels, each connected to a respective gate line and a respective data line. Each of the pixels has a longer side in parallel with gate lines and a shorter side in parallel with the data lines. A number of the gate clock control signals is an integer multiple of a number of colors of the pixels.

Abstract: A display apparatus includes a display panel, a gate driver and a data driver. The display panel displays an image. The gate driver outputs gate signals to the display panel. The data driver outputs data voltages to the display panel. The data driver includes a plurality of data driving circuits. At least two data driving circuits among the data driving circuits have different turn off timings or different turn on timings in a vertical blank period.
