Embodiment Construction

[0025] Please refer to FIG. 1 . FIG. 1 is a schematic diagram of an exploded structure of an embodiment of the present invention. It is a field-sequentially driven color liquid crystal display device 100 , including a first field-sequentially driven color liquid crystal display element 110 and a second field-sequentially driven color liquid crystal display element 120 . The first and second field-sequence-driven color liquid crystal display elements 110, 120 are high-speed TN liquid crystal screens (the TN222 series high-speed TN liquid crystal screens produced by Shenzhen Secco Display Co., Ltd. can be selected for use), of course, the aforementioned high-speed TN liquid crystal screens It can also be replaced by a high-speed OCB LCD screen, a high-speed FLC LCD screen or a high-speed AFLC LCD screen. The first and second field-sequence-driven liquid crystal display elements 110 and 120 are superposed. The first and second field-sequentially driven liquid crystal display ele...

Abstract

The invention discloses a field sequence driving color LCD device and a driving method thereof. The device comprises a first field sequence driving color LCD element (110) and a second field sequence driving color LCD element (120). The first field sequence driving color LCD element (110) and the second field sequence driving color LCD element (120) are superposed and are in a normal white mode, and a backlight source (130) is arranged below the first field sequence driving LCD element (110). The method has the advantages of increasing one or more field sequence driving color LCD elements with a little higher cost, and being capable of achieving the purpose of improving display capacity of the color LCD device by one fold or a plurality of folds without affecting the display effect..

Description

technical field [0001] The invention relates to a color liquid crystal display device, in particular to a field sequentially driven color liquid crystal display device and a driving method thereof. Background technique [0002] As a method of displaying the color of a color display element, there is a method called a field sequential method. This method is to sequentially place B (blue), Y (yellow) or R (red) in a color picture (frame) in time. , G (green), and B (blue) are divided into two or three pictures (fields), and then those pictures (fields) are switched sequentially at high speed to form a color picture (frame), as shown in the attached Figure 8 shown, with Figure 8 It is a schematic diagram of three screens (fields) divided by R (red), G (green), and B (blue), and 8 colors are produced in conjunction with the opening or closing of the liquid crystal display element. If it repeats so quickly that the flicker cannot be recognized, the colors are mixed according to...
