    • 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.
    • 显示装置包括显示面板,数据驱动部和门驱动部。 显示面板包括第一像素行。 第一像素行包括连接到第(n + 1)栅极线和第(m + 1)数据线(其中'n'和'm'是自然数)的第一像素,并且第二像素连接 到第n个栅极线和第(m + 2)个数据线。 数据驱动部分对第(m + 1)数据线施加相对于参考电压具有第一极性的数据电压,并将相对于参考电压具有第二极性的数据电压施加到第(m + 2)数据线。 栅极驱动部分顺序地对第n条栅极线和第(n + 1)栅极线施加栅极信号。

    • 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.

    • 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.
    • 栅极驱动电路包括彼此连接的多个级。 第m级(“m”是自然数)级包括上拉部分,下拉部分,第一保持部分和第二保持部分。 响应于施加到第一输出控制部分的高电压,上拉部分输出作为第m门信号的高电压的时钟信号的高电压。 下拉部分响应于第(m + 1)门信号的高电压将第m门信号的高电压下拉到第一低电压。 第一保持部分将施加到第一输出控制部分的电压保持为具有低于第一低电压电平的第二低电压。 第二保持部将第m栅极信号的低电压保持为第一低电压。
