    • A source driver circuit provides a source driving signal to a disconnected source line. The source driver circuit includes a shift register, a latch unit, a DAC unit, a buffer unit, and a source line repair circuit. A source line repair circuit receives a common voltage signal and a source driving signal corresponding to the disconnected source line, selects an amplifier having a same polarity type as a polarity type of an amplifier constituting the buffer unit in response to a source driving signal to provide an output signal of the selected amplifier to the disconnected source line. The source driver circuit includes the source line repair circuit which may select the amplifier having the same polarity as the polarity of the amplifier of the buffer, and thus may safely provide the source driving signal to the disconnected source line.
    • 源极驱动器电路向源极线提供源极驱动信号。 源极驱动器电路包括移位寄存器,锁存单元,DAC单元,缓冲单元和源极线修复电路。 源极线修复电路接收与断开的源极线相对应的公共电压信号和源极驱动信号,响应于源极驱动信号选择具有与组成缓冲器单元的极性类型相同的极性类型的放大器,以提供 所选择的放大器到断开的源极线的输出信号。 源极驱动器电路包括可以选择具有与缓冲器的放大器的极性相同极性的放大器的源极线修复电路,从而可以安全地将源极驱动信号提供给断开的源极线。

    • In a gamma correction digital-to-analog converter, one of first gamma correction reference voltage signals is selected as a first corresponding gray scale signal based on lower m+n bits of a k bit digital input signal when upper l bits of the k bit input signal correspond to an upper or lower code set, where k=l+m+n, and where k, l, m and n are integers. A pair of adjacent second gamma correction reference voltage signals is selected from second gamma correction reference voltage signals based on upper l+m bits when the upper l bits correspond to a middle code set, and one is selected from the pair of second gamma correction reference voltage signals and 2n−1 divided signals as a second corresponding gray scale signal, the divided signals being obtained by dividing an interval between the selected pair into 2n levels. The first or second gray scale signal is selected to be output.
    • 在伽马校正数模转换器中,当k位输入的高1位时,基于ak位数字输入信号的较低m + n位选择第一伽马校正参考电压信号之一作为第一对应灰度信号 信号对应于上或下码集,其中k = 1 + m + n,其中k,l,m和n是整数。 当高位比特对应于中间码组时,从第二伽马校正基准电压信号中选择一对相邻的第二伽马校正参考电压信号,并且从一对第二伽马校正基准 电压信号和2 n + 1分割信号作为第二对应的灰度信号,所分割的信号通过将所选择的一对之间的间隔除以2级来获得。 第一或第二灰阶信号被选择输出。
