显示器驱动设备
摘要：
一种显示器驱动设备可以包括接口、时钟发生器、同步信号发生器和时序控制器。所述接口接收具有第一垂直周期的第一垂直同步信号、具有比第一垂直周期短的第一水平周期的第一水平同步信号以及图像数据。时钟发生器产生具有预定频率的时钟信号。同步信号发生器使用所述第一垂直同步信号来产生第二垂直同步信号，并且当包括在所述第一垂直周期中的边沿时段大于预定参考值时，使用所述时钟信号来产生具有与所述第一水平周期不同的第二水平周期的第二水平同步信号。所述时序控制器基于第二垂直同步信号和第二水平同步信号来驱动显示器面板。
摘要（英）：

A display driving device includes an interface, a clock generator, a sync signal generator and a timing controller. The interface receives a first vertical sync signal having a first vertical period,a first horizontal sync signal having a first horizontal period shorter than the first vertical period, and image data. The clock generator generates a clock signal having a predetermined frequency. The sync signal generator generates a second vertical sync signal using the first vertical sync signal, and generates a second horizontal sync signal having a second horizontal period different from the first horizontal period, using the clock signal, when a porch period included in the first vertical period is greater than a predetermined reference value. The timing controller drives a display panel based on the second vertical sync signal and the second horizontal sync signal.
