  • Patent number: 10978012
    Abstract: A display device capable of setting an optimal output enable value according to a color pattern and a method for driving the display device. A timing controller is configured to receive an image signal from an external source, identify a color pattern and set an output enable value corresponding to the identified color pattern. A scan driver is configured to receive the output enable value and generate a first scan signal having a first turn-on signal and a second scan signal adjacent to the first scan signal and having a second turn-on signal. The scan driver may adjust an interval between the first turn-on signal and the second turn-on signal based on the output enable value.

  • Patent number: 10147384
    Abstract: A boosting voltage generator includes a switching circuit, a control circuit and a boosting circuit. The switching circuit is connected to a first input terminal receiving a first frame signal and a second input terminal receiving a second frame signal, and generates a first switching signal and a second switching signal based on a voltage at the first input terminal and a voltage at the second input terminal. The second frame signal has a phase opposite to that of the first frame signal. The control circuit is connected to the first and second input terminals, and selectively connects the first and second input terminals with a ground voltage based on a mode selection signal. The boosting circuit generates a first boosting voltage and a second boosting voltage based on the first switching signal, the second switching signal, a first feedback voltage and a second feedback voltage.

  • Patent number: 9799285
    Abstract: A display apparatus includes a display panel which displays an image, a compensation area determiner which divides a display area of the display panel into a compensation area and a normal area, a compensation coefficient determiner which determines a compensation coefficient corresponding to input data of the compensation area, a compensation look up table which stores a noise compensation data which compensates a luminance difference of the compensation area by an interference noise of a light-source driving signal, and a correction data calculator which calculates a correction data corresponding to the input data of the compensation area using the compensation coefficient and the noise compensation data.
