Patent ID: 7864152

Claim:
A field sequential color type liquid crystal display comprising: a LCD panel that has a plurality of pixels arranged in a matrix form defined by gate lines and data lines that cross each other; a memory configured to store a first user-set data which includes a horizontal period, a second user-set data which includes a wait period of liquid crystals and a third user-set data which includes a flash period of driving a backlight unit, the first to third user-set data being variable; a horizontal period variation unit that receives a frame frequency, selects 1 horizontal period corresponding to the frame frequency according to the first user-set data from the memory; a wait period variation unit that varies a wait period according to the 1 horizontal period and the second user-set data from the memory; a flash period variation unit that varies a flash period according to the 1 horizontal period and the third user-set data from the memory; a timing controller that produces and outputs a gate control signal and a data control signal that corresponds to the 1 horizontal period and the wait period and a light source control signal corresponding to the wait period and a re-aligned pixel data; a gate driver that sequentially outputs a scan pulse to the gate lines according to the gate control signal; and a data driver that outputs a data voltage to the data lines every 1 horizontal period according to the data control signal, wherein the backlight unit that sequentially outputs red, green and blue light to the pixels according to the light source control signal, wherein one frame comprises three sub-frames of red, green and blue, and each of the sub-frames is composed of three sub-fields that consists of a variable addressing period that corresponds to the 1 horizontal period, the wait period and the flash period.
