Abstract: The present invention discloses a color sequence offset modulation method and device, which modulates the colored backlights of a multi-color backlight source to have a dark interval in the time points of shifting the colored backlights and makes the dark interval coincide with the close delay interval caused by the delayed response of liquid crystal, whereby the latter colored backlight will not mix with the former colored backlight during the close delay interval, wherefore the present invention can avoid the color deviation caused by color mixing and can present the designed colors correctly.

Abstract translation: 本发明公开了一种色序偏移调制方法和装置，其调制多色背光源的彩色背光在移动着色背光的时间点具有暗区间，并使暗区间与紧密延迟间隔一致 这是由于液晶的延迟响应引起的，由此后一种彩色背光源在闭合延迟时间间隔内不会与前一种彩色背光混合，因此本发明可以避免颜色混合引起的颜色偏差，并可以正确地呈现设计的颜色。
