Driving method for dynamically driving a field sequential color liquid crystal display

摘要

A driving method for dynamically driving a field sequential color liquid crystal display is characterized in that a backlight includes at least two or more different colors, a plurality of fields constitute one frame, each field includes scanning time, non-scanning time of COMs and the time when the backlight is turned off. All liquid crystal pixels are driven by scanning each COM in a certain order during the scanning time. The non-scanning time is the time during which all liquid crystal pixels are not driven while the backlight continues to be bright after the scanning time. The time when the backlight is turned off is the time when all liquid crystal pixels are not driven while the backlight is turned off after the non-scanning time. The sum of two kinds of time mentioned above is larger than or equal to 1 ms and less than or equal to 10 ms.

主权项

1. A driving method for dynamically driving a field sequential color liquid crystal display with a backlight having at least two different colors, comprising:
providing a field comprising a scanning time and a non-scanning time of COMs; providing a frame consisting of a plurality of fields; and driving all liquid crystal pixels by scanning each COM in a certain order during the scanning time, wherein the non-scanning time is a time during which all liquid crystal pixels are not driven while the backlight continues to be bright after the scanning time, and the non-scanning time is between 1 ms and 10 ms, wherein a time when the backlight is turned on lags behind a start time when the COM is initially scanned, a delay of the time when the backlight is turned on is between 0.5 and 2.0 ms.
