    IPC: H02M3/156 ,  H03F3/14

    Abstract: A power voltage generator includes a booster, a voltage sensor, a constant voltage controller and a constant current controller. The booster is configured to boost an input voltage to an output voltage based on an on-off operation of a switch. The voltage sensor is configured to generate a sensing voltage by sensing the output voltage. The constant voltage controller is configured to generate a first switching signal to control the switch by comparing the sensing voltage with a reference voltage. The constant current controller is configured to generate a gain based on a ratio of an electrode signal of the switch and a target signal by comparing the electrode signal of the switch with the target signal.

    Abstract: A display device includes a display panel. The display panel includes a display panel including a data line, a sensing line, and pixels coupled to the data line and the sensing line. A timing controller generates clock embedded data including image data and a clock training signal. A data driver recovers a clock signal, based on the clock training signal of the clock embedded data, recovers the image data of the clock embedded data, based on the clock signal, supplies a data voltage corresponding to the image data to the data line in a first section, and receives a sensing signal from a pixel of the pixels through the sensing line in a second section different from the first section. In the second section, the data driver recovers the clock signal while the sensing signal is being received.
