    • A level shifter for a gate driver has a driving transistor, a reset transistor, a charge/discharge circuit, a threshold voltage detector, and a memory capacitor. An initial threshold voltage of the driving transistor is detected by the threshold voltage detector, and then memorized in the memory capacitor. The charge/discharge circuit charges or discharges the capacitor, and receives a control signal to actuate the level shifter. The reset transistor receives an output signal of a next stage level shifter as a reset signal, so as to restore the initial status of the level shifter. In this way, the driving current output from the level shifter is irrelevant to the threshold voltage of the driving transistor.
    • 用于栅极驱动器的电平移位器具有驱动晶体管,复位晶体管,充电/放电电路,阈值电压检测器和存储电容器。 驱动晶体管的初始阈值电压由阈值电压检测器检测,然后存储在存储电容器中。 充电/放电电路对电容器进行充电或放电,并接收控制信号以致动电平转换器。 复位晶体管接收下一级电平移位器的输出信号作为复位信号,以恢复电平移位器的初始状态。 以这种方式,从电平移位器输出的驱动电流与驱动晶体管的阈值电压无关。

    • A central symmetric Gamma voltage correction circuit is mainly applied to the displaying circuit of liquid-crystal display. By installing a resistor voltage dividing circuit and a driving circuit so that a well adjustment way to the Gamma correction voltage can be acquired. Moreover, the value of the Gamma correction voltage is controlled by externally inputting voltage, and thus the number of external correction reference voltage input externally and the number of the amplifiers are reduced. The resistor voltage dividing circuit and driving circuit are formed by a plurality of resistors, adjustable resistors and amplifiers so as to achieve the object of reducing the number of externally inputting correction voltages and the number of amplifiers.
