Problems solved by technology

[0004] However, the current field-sequential full-color technology is severely limited in application because the response time of liquid crystals is generally slow.
figure 1 It is the current field-sequential full-color (Field-SequentialColor, FSC) response method. The disadvantage of this method is that the backlight module (Back Light Unit, BLU) light-emitting time will be compressed by the IC data writing and liquid crystal response time, resulting in backlight module The luminous time is too small, so it is not easy to achieve
In addition, the response time from gray scale to gray scale will be relatively long when some gray scales are switched, making it impossible to switch to the correct gray scale within the specified time, resulting in image display errors

Embodiment Construction

[0020] The present invention relates to a field-sequential color display reaction structure and method, especially in a liquid crystal device containing a plurality of pixels and a backlight module in the display process, the backlight module at least includes a first, a second and a The third primary color light source, and in a first primary color sub-frame, continuously illuminates the first primary color light source, and transmits a plurality of data signals to the plurality of pixels; before the end of the first primary color sub-frame, the plurality of pixels are driven Pixels to a specific gray scale and turn on the second primary color light source and the third primary color light source respectively in a second primary color subframe and a third primary color subframe, and repeat the above steps to drive the liquid crystal display device. In other words, as each display data sequence is input, the backlight module synchronously emits light to light up the primary colors...

Abstract

The invention relates to a field order type liquid crystal display device and a driving method of the device, when lightening a light source, reading-in color data and driving all the pixels on the liquid crystal display device to a specific gray scale. The displayed original color can be orderly alternated in turn at least with the three colors of red, green and blue, and the time of reading-in the original color data is the same with that of the specific gray scale, thereby a backlight module can eliminate the time of liquid crystal reflection during the display process, and the control of the original color data read-in and the driving of the specific gray scale can be executed by the same control IC.

Description

Technical field [0001] The present invention relates to a field-sequential color display response architecture and method, and more particularly to a backlight module that has started to emit light to light up the primary color when each display data sequence is input in the liquid crystal display process and before the primary color is displayed. Drive all pixels on the liquid crystal display to a specific gray scale to realize the response of field sequential color display. Background technique [0002] With the vigorous development of the flat-panel display industry and the rapid development of display technology, the flat-panel display device Liquid Crystal Display (LCD), in terms of mass production scale, is firmly in the top of the flat-panel display. In order to maintain the existing competitive advantages of LCD display technology, a large amount of research and development resources and manpower have been invested to improve the performance and display quality of traditi...
