Embodiment
The invention provides a kind of liquid crystal display, comprise display panel, backlight module and driver module, wherein, the filter sheet base plate of described display panel comprises many group filter unit, and every group of filter unit comprises Red lightscreening plate, blue color filter and transparent optical filter; Described backlight module comprises the first backlight and green glow backlight, and described the first backlight adds red fluorescence powder encapsulation by blue light emitting chip and forms.
In order to set forth better technical characterstic of the present invention and structure, below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
Consulting Fig. 3, is the liquid crystal display that the present embodiment provides, and comprises backlight module 40, display panel 20 and driver module 50.Wherein, display panel 20 comprises according to the lower polarizing layer 21 setting gradually away from backlight module 40 directions, array base palte 23, liquid crystal layer 25, filter sheet base plate 26 and upper polarizing layer 22.
Filter sheet base plate 26 comprises many group filter unit, every group of filter unit comprises the Red lightscreening plate 261, transparent optical filter 262 and the blue color filter 263 that set gradually, certainly, in other embodiments, the position of Red lightscreening plate 261, transparent optical filter 262 and blue color filter 263 can arbitrarily convert.Wherein, Red lightscreening plate 261 is made up of red resin, and blue color filter 263 is made up of blue resins, and transparent optical filter 262 is made up of transparent material.In a kind of preferred embodiment, Red lightscreening plate 261, transparent optical filter 262 and blue color filter 263 have similar width.Display panel 20 is provided with and corresponds respectively to the red sub-pixel of Red lightscreening plate 261, blue color filter 263 and transparent optical filter 262, blue sub-pix and transparent sub-pix.
Backlight module 40 is provided with the first backlight 41 and green glow backlight 42, and wherein, the first backlight 41 adds red fluorescence powder encapsulation by blue light emitting chip 411 and forms, and green glow backlight 42 is formed by 421 encapsulation of green emitting chip.Driver module 50 is for driving backlight module 40 and display panel 20, and wherein the first backlight 41 and the green glow backlight 42 in backlight module 40 controlled respectively by driver module 50.
The liquid crystal display that the present embodiment provides is quick response device, and in a kind of preferred embodiment, it is 120Hz that driver module 50 drives the frequency of backlight module 40 and display panel 20.Driver module 50, in the time of odd-numbered frame/even frame, drives the first backlight 41 luminous, drives red sub-pixel, blue sub-pix and transparent sub-pix to show simultaneously; In the time of even frame/odd-numbered frame, drive green glow backlight 42 to show, drive transparent sub-pix to show simultaneously.By image frame, the color in this pixel determines the size of the GTG that wherein, red sub-pixel, blue sub-pix and transparent sub-pix show.
Based on same inventive concept, it is a kind of for driving the driving method of liquid crystal display as above that the present embodiment also provides.This driving method is divided into two frames by piece image and shows: the first frame, and drive the first backlight 41 luminous, drive red sub-pixel, blue sub-pix and transparent sub-pix to show simultaneously; The second frame, drives green glow backlight 42 to show, drives transparent sub-pix to show simultaneously.Certainly, in other embodiments, the demonstration of the first frame and the second frame can exchange order.Like this, in the time of the first frame, red sub-pixel and blue sub-pix show respectively redness and blueness, transparent sub-pix shows the magenta of being sent by the first backlight 41, due to the demonstration of transparent sub-pix, improve the luminous utilization factor of the first backlight 41, thus the use of having saved blue reflective chip 411, and then the cost of reduction backlight module 50.Simultaneously, consult table 1, the mode that adopts blue light emitting chip 411 to add red fluorescence powder due to the first backlight 41 encapsulates and forms, in the time of the demonstration of the first frame, Red lightscreening plate 261, transparent optical filter 262 and blue color filter 263 will be higher than the white light sources providing in prior art to the transmitance of this first backlight 41, thereby reduced further cost backlight.In the time of the second frame, red sub-pixel and blue sub-pix are not luminous, and transparent sub-pix sends optical filtering, because the transmittance of transparent sub-pix is larger, have therefore improved the utilization factor of green glow backlight 42.Because this driving method is that response drives fast, its driving frequency is preferably 120Hz, and the highest frequency of human eye resolution things is 24Hz, and what therefore in the time watching, see is the first frame and the mixed image of the second frame.Further, drive the size of the GTG of red sub-pixel, blue sub-pix and the demonstration of transparent sub-pix to be determined by the information of this image frame, therefore, last seen image is the image that wish will show.
The colourity simulation table of the first frame when table 1 this programme and existing scheme show with picture
| Backlight module | Red sub-pixel | Transparent sub-pix | Blue sub-pix | Total through rate |
| (R+G)+rouge and powder | 0.68% | 4.75% | 0.3% | 5.72% |
| B+ rouge and powder | 2.17% | 2.17% | 0.47% | 7.55% |
Eventually the above, Liquid Crystal Display And Method For Driving provided by the invention, not only can reduce by being arranged at transparent optical filter on filter sheet base plate the loss of backlight, improves the utilization factor of backlight; But also can encapsulate the first backlight forming by added red fluorescence powder by blue light emitting chip, reduce the use of green emitting chip; Meanwhile, this liquid crystal display also has higher color representation power.
