    • A liquid crystal display device includes a plurality of gate lines, a plurality of data lines, a pixel array, a gate driver, a timing controller, and an optimization circuit. Each pixel unit in the pixel array displays images according to the gate driving signal received from a corresponding gate line and the data driving signal received from a corresponding data line. According to an optimized reference value, the timing controller provides an output enable signal, based on which the gate driver outputs the gate driving signals. The optimization circuit receives a first grayscale data related to display images of a row of pixel units in a first driving period and a second grayscale data related to display images of the row of pixel units in a second driving period, and provides the optimized reference value according the difference between the first and second grayscale data.
    • 液晶显示装置包括多条栅极线,多条数据线,像素阵列,栅极驱动器,定时控制器和优化电路。 像素阵列中的每个像素单元根据从对应的栅极线接收的栅极驱动信号和从相应的数据线接收的数据驱动信号来显示图像。 根据优化的参考值,定时控制器提供输出使能信号,基于该输出使能信号,栅极驱动器输出栅极驱动信号。 优化电路在第二驱动周期中接收与第一驱动周期中的一行像素单元的显示图像相关的第一灰度数据和与第二驱动周期中的该像素单元的显示图像相关的第二灰度数据,并且提供优化的参考值 根据第一和第二灰度数据之间的差异。
