Abstract
The invention discloses a method for driving a field sequential liquid crystal display device. The liquid crystal display device comprises a plurality of monochromatic backlight sources. The driving method comprises the following steps of: a) dividing each frame image into a plurality of monochromatic sub frame images; and b) outputting data, and then turning on the monochromatic backlight source corresponding to the current monochromatic sub frame image. The method for driving the field sequential liquid crystal display device eliminates color separation caused by the liquid crystal response speed problem by using a time difference when the backlight is turned on after the data are sent to the field sequential liquid crystal display device and displayed for a certain period of time, effectively improves the color separation in the field sequential liquid crystal display, has an obvious effect and is simple and easy to implement.
Description
Technical field
The present invention relates to a kind of driving method of liquid crystal indicator, relate in particular to a kind of driving method of field order LCD device.
Background technology
TFT-LCD has obtained significantly popularizing through years of development, is widely used in TV, display and a lot of palm recreational product display screen and comes into huge numbers of families.These are that the product of main display unit mostly can both color display with TFT-LCD, its principle realizes the mode of the synthetic pixel of three sub-pixels of red, green, blue by chromatic color filter (Color Filter), and this is our spacing color mixed method of often saying just.Because there are unfavorable factors such as the chromatic color filter cost is higher, light transmission rate is lower in spacing color mixed method, industry begins to research and develop a kind of novel liquid crystal indicator, promptly utilizes the field sequential liquid crystal of time mixed-color method to show.This device is made up of liquid crystal display device and the red, green, blue three look backlights that can control respectively.In the time of a frame, cooperatively interact with liquid crystal display device by red, green, blue three looks backlight, reach the colored effect that shows.Be exactly that liquid crystal display device is output red parts of images data simultaneously when the some shiny red is backlight specifically; When lighting green colored backlights, liquid crystal display device is exported the green portion view data simultaneously; When a sapphirine was backlight, liquid crystal display device is output blue parts of images data simultaneously.But some also can appear in field sequential liquid crystal in some cases allows the unacceptable problem of people, such as the look segregation phenomenon.
" smear " phenomenon that the look segregation phenomenon exists from essence is made peace general liquid crystal display device is similar.For instance, as shown in Figure 1, when a bead rapidly moves to 2. position from 1. position, shade as shown in the figure can appear, the promptly normal smear phenomenon that claims on the left side of bead.
And for the field sequential liquid crystal display mode, for instance, as shown in Figure 2, when a white box rapidly moves to 4. position from 3. position, color transition band to white (stacks of red, green, blue three looks) can appear from redness to yellow (red and green stack) in the right of square frame again, then can occur from the blueness to the cyan (blue and green stack) on the left side of image and arrive the color transition band of white (stacks of red, green, blue three looks), look segregation phenomenon that Here it is again.The existence of this phenomenon has had a strong impact on image quality, allows the people be difficult to accept, and has seriously restricted the development of field sequential liquid crystal.
In order to solve the look segregation phenomenon, industry has proposed some solutions, method of upsetting the sub-field sequence of red, green, blue that proposes by CN200810204161.7 such as black plug frame technique, four look technology and Chinese patent application number etc.But all there are some shortcomings respectively in these methods, can't well solve the look separation problem.Such as the black plug frame technique, require sub-field frequencies range to reach more than the 360Hz, this method not only be difficult to realize concerning Circuits System, and also is difficult to reach (field frequency 360Hz is about 2.7ms at the field duration, promptly requires response speed more than 2.7ms) for response speed of liquid crystal; Four-colour process is exactly to increase a yellow son in fact again on former red, green, blue three a son basis, this method segregation phenomenon of checking colors has some improvement, but acts on less; Chinese patent application number is the method for upsetting the sub-field sequence of red, green, blue that CN200810204161.7 proposed, as shown in Figure 3, under the normal field sequential mode, frequency between three son fields of red, green, blue in each frame is 180Hz, frequency between per two frames between the red color sub-field is 60Hz, equally, between two frames between green and the blueness frequency also be 60Hz.Under patent N200810204161.7 mode, frequency between three son fields of red, green, blue in each frame still is 180Hz, but between two frames, be example with the green among the figure, the phenomenon that 90Hz, 36Hz cross occurrence can occur, this phenomenon is exactly tangible scintillation on showing and showing, and flicker is the more unacceptable problem of colorimetric separation.
Summary of the invention
Technical matters to be solved by this invention provides a kind of driving method of field order LCD device, can effectively improve the look segregation phenomenon in the field sequential liquid crystal demonstration.
The present invention solves the problems of the technologies described above the driving method that the technical scheme that adopts provides a kind of field order LCD device, described liquid crystal indicator comprises a plurality of monochromatic backlights, and wherein: described driving method comprises the steps: a) each two field picture to be divided into a plurality of monochromatic sub-frame images; B) the monochromatic backlight with current monochromatic sub-frame images correspondence is opened in the output of advanced line data again.
In the driving method of above-mentioned field order LCD device, described a plurality of monochromatic backlights are red, green, blue three look backlights, and each two field picture is divided into red, green, blue three dice two field pictures.
The present invention contrasts prior art following beneficial effect: the driving method of field order LCD device provided by the invention, in the son field of correspondence, the backlight of correspondence opened in the output of advanced line data again.That is to say, data delivered on the field sequence LCD device spare open again after showing a period of time backlight, that is to say and make the liquid crystal upset earlier, and then open backlight, utilize this mistiming to eliminate because the look segregation phenomenon that the liquid crystal response speed issue is brought, effectively improve the look segregation phenomenon of field sequential liquid crystal in showing, effect obviously and be simple and easy to realize.
