  • Patent number: 10777144
    Abstract: In a method of operating a display panel, a plurality of data lines are divided into a first data line group through an N-th data line group, where N is a natural number equal to or greater than two. Each of the first through N-th data line groups includes at least two data lines. The first through N-th data line groups are sequentially driven by applying first data voltages through N-th data voltages to the first through N-th data line groups, respectively at different times. A first number of data lines in the first data line group is variable.

  • Patent number: 9947295
    Abstract: A method of driving a display device including a display panel is provided. The display panel includes a plurality of gate lines. The gate lines are divided into a plurality of gate line groups. The method includes applying different gate delay values to each of the gate line groups to generate gate signals and outputting the gate signals to the gate lines. A first gate delay value is applied to at least one of the gate lines during a first frame and a second gate delay value different from the first delay value is applied to the at least one of the gate lines during a second frame.

  • Patent number: 9633595
    Abstract: A display apparatus includes a display panel, a gate driver and a data driver. The display panel includes gate lines, data lines and pixels electrically connected to the gate lines and the data lines. The gate driver is disposed adjacent to a first side of the display panel, and outputs a gate signal to the gate line. The data driver is disposed adjacent to the first side of the display panel, and outputs a data voltage to the data line. A gate signal applied to a position having a low resistance-capacitance (“RC”) delay of the gate line has a kickback slice greater than a kickback slice of a gate signal applied to a position having a high RC delay of the gate line. The kickback slice is defined as a portion having a level lower than a gate-on voltage level in a gate pulse of the gate signal.
