    摘要: A gate drive circuit includes a plurality of driving stages. An n-th (‘n’ is a natural number) driving stage includes a pull-up part, a carry part, a first pull-down part, a first pull-up/down control part and a second pull-up/down control part. The first pull-up/down control part applies a first power signal of an ON voltage to a control terminal of the pull-up part in a forward direction mode, and applies the first power signal of a second OFF voltage to a control terminal of the pull-up part in a reverse direction mode. The second pull-up/down control part applies a second power signal of the second OFF voltage to the control terminal of the pull-up part in the forward direction mode, and applies the second power signal of the ON voltage to the control terminal of the pull-up part in the reverse direction mode.

    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.

    摘要: A display device includes a display panel, a data driving part and a gate driving part. The display panel includes a first pixel row. The first pixel row includes a first pixel connected to an (n+1)-th gate line and an (m+1)-th data line (where ‘n’ and ‘m’ are natural numbers), and a second pixel connected to an n-th gate line and an (m+2)-th data line. The data driving part applies a data voltage having a first polarity with respect to a reference voltage to the (m+1)-th data line, and applies a data voltage having a second polarity with respect to the reference voltage to the (m+2)-th data line. The gate driving part sequentially applies a gate signal to the n-th gate line and the (n+1)-th gate line.

    摘要: A gate driving circuit includes a plurality of stages connected to each other. An m-th stage (‘m’ is a natural number) of the stages includes a pull-up part, a pull-down part, a first holding part and a second holding part. The pull-up part outputs a high voltage of a clock signal as a high voltage of an m-th gate signal in response to a high voltage applied to a first output control part. The pull-down part pulls down the high voltage of the m-th gate signal to a first low voltage in response to a high voltage of an (m+1)-th gate signal. The first holding part holds a voltage applied to the first output control part as a second low voltage having a level lower than the first low voltage. The second holding part holds a low voltage of the m-th gate signal to the first low voltage.
