运用于影像显示的时序控制器及其控制方法;TIMING CONTOLLER FOR IMAGE DISPLAY AND ASSOCIATED CONTROL METHOD

摘要

一种运用于面板显示系统的时序控制器，包括：影像信号接收器，接收影像信号；过驱电路，接收影像信号接收器输出的影像信号，并根据影像信号中连续的第一图框资料与第二图框资料来产生转换影像信号；影像信号传输器，接收过驱电路输出的转换影像信号并传递至显示面板；记忆体；记忆体介面单元，接收过驱电路输出的第一图框资料并暂存于记忆体，当过驱电路接收影像信号中的第二图框资料时，记忆体介面单元读取记忆体中的第一图框资料并传递至过驱电路。当决定一记忆体校正周期时，记忆体介面单元复数次调整一取样时脉的一延迟相位，并据以取样记忆体产生的一读取信号，而获得复数个比较结果；以及，根据该些比较结果产生一较佳延迟相位。; an overdrive circuit capable of receiving the image signal and generating a transferred image signal in response to a first frame data and a second frame data of the image signal; an image transmitter capable of transmitting the transferred image signal to a display panel; a memory; a memory interface unit capable of writing the first frame data from the overdrive circuit into the memory, and reading the first frame data from the memory to the overdrive circuit when the overdrive receives the second frame data from the image signal receiver; wherein when a memory calibration period is determined, the memory interface unit adjusts a delay phase of a sampling clock a plurality of times to sample a read signal of the memory and generates a plurality of comparison results; and the memory interface unit determines a better delay phase in response to the comparison results.
