    摘要： A display apparatus includes a gate driver, a data driver, a display panel, a power supply and a common voltage line. The gate driver outputs a gate signal, and the data driver outputs a data signal. The display panel includes a display area displaying images in response to the gate signal and the data signal, and a peripheral area surrounding the display area. The power supply generates a common voltage and supplies the common voltage to the display panel. The common voltage line is disposed in the peripheral area surrounding the display area. and the common voltage line has two ends adjacent to the power supply. One of the two ends, which is disposed farther away from the gate driver, is connected to the power supply to receive the common voltage. Accordingly, the common voltage is differentially applied according to a length of the common voltage line.

    摘要： A display apparatus includes a panel part, a data driver, and a gate driver. The panel part includes a plurality of gate lines, a plurality of data lines, and a plurality of pixels each of which is connected to one gate line of the gate lines and one data line of the data lines. The data driver receives image data and outputs a data signal to the data lines. The gate driver part is disposed on the panel part and applies gate signals to the gate lines. Periods of clock signals controlling the level of the gate signals are different from that of the gate signals. Thus, power consumption of the display apparatus is substantially effectively reduced.

    摘要： A gate drive circuit includes a shift register in which plural stages are cascade-connected to each other. In an n-th stage, a pull-up part outputs a high voltage of a clock signal to an output node as a high voltage of an n-th gate signal in response to a high voltage on a first node. A pull-down part pulls the high voltage of the n-th gate signal down to a first low voltage in response to an (n+1)th carry signal. A discharging part discharges the first node to a second low voltage level lower than the first low voltage level in response to the (n+1)th carry signal. A carry part outputs the high voltage of the clock signal as an n-th carry signal (mirroring the n-th gate signal) in response to a high voltage on the first node.

    摘要： A method of driving a display panel includes applying a common voltage to the display panel, sensing a frequency of the display panel to generate a frequency signal, adjusting a gain of an operational amplifier based on the frequency signal, receiving a feedback common voltage from the display panel, and compensating the common voltage using an input resistor, the operational amplifier and a feedback resistor based on the feedback common voltage to apply the compensated common voltage to the display panel. The operational amplifier includes an inverting input terminal connected to the input resistor, a non-inverting input terminal to which a reference common voltage is applied and an output terminal. The feedback resistor is between the inverting input terminal and the output terminal.
