Abstract
The utility model discloses a field sequence driven multicolor liquid crystal display which comprises two or more backlight sources with different colors, a field sequence driven backlight source driving circuit, a liquid crystal display and a liquid crystal display driving circuit, wherein the liquid crystal display adopts a negative-display liquid crystal display displaying in the dark when not being powered up. The field sequence driven multicolor liquid crystal display has the advantages of not only being capable of displaying basic colors, but also having obvious contrast between the displayed colors and the base color of the display, and having low cost.
Description
Technical field
The utility model relates to a kind of polychrome device of liquid crystals, and especially a kind of preface drives polychrome device of liquid crystals.
Background technology
At present, the liquid display panel of colour or polychrome adopts the TFT pattern mostly, and still, this pattern is because its manufacturing price costliness is restricted its range of application.But,, be LCD with low cost again if having a lot of occasions to need again to adopt both can to have shown polychrome.As various displays as instrument and meter.Preface drives colour or polychrome device of liquid crystals, and it is low to have a cost, can keep lower price again, existing by these occasion widespread uses.Present field preface drives colour or polychrome device of liquid crystals, because the restriction of liquid crystal material, basically be just to show a preface to drive colour or polychrome device of liquid crystals, this field preface that is just showing drives colour or polychrome device of liquid crystals is pellucidity owing to it when not powering up, so in many occasions, the background color contrast of color that the LCD that makes is shown and display itself is not clearly.Therefore, press for a kind of negative preface that shows on the market and drive polychrome device of liquid crystals.
The utility model content
The utility model provides a kind of to society can not only show basic color, and the tangible preface of the background color contrast of color that shows and display itself drives polychrome device of liquid crystals.
The technical scheme in the invention for solving the above technical problem is: designs a kind of preface and drives polychrome device of liquid crystals, comprise backlight with different colours more than 2 kinds or 2 kinds, and the backlight source driving circuit of a preface driving; LCDs and LCDs driving circuit thereof, described LCDs are to be to show slinkingly the negative LCDs of showing that shows when not powering up.
As to improvement of the present utility model, described LCD is the LCD of TN, VA, STN or FSTN mode.
As to further improvement of the utility model, the quantity in described backlight different colours lamp source is unequal.
As further improving of the present utility model, described backlight is divided into two look districts a frame demonstration time.
As further improving to of the present utility model, at least one look district, be provided with the lamp source of two kinds of different colours, the quantity in the lamp source of two kinds of different colours is unequal.
As further improving of the present utility model, the only complementation in two look districts is white light when lighting simultaneously.
Described backlight is LED, CCFL or OLED.
LCDs driving circuit described in the utility model can be a static drive, also can be dynamic driving.
The utlity model has and can not only show basic color, and the color that shows and the tangible advantage of background color contrast of display itself, the utility model also has cheap advantage.

Fig. 2 is a drive principle frame structure synoptic diagram embodiment illustrated in fig. 1.
Fig. 3 is the color synoptic diagram of the utility model when adopting three look backlights.
Fig. 4 is the color synoptic diagram of the utility model when adopting two look backlights.
Embodiment
See also Fig. 1 and Fig. 2, what Fig. 1 and Fig. 2 disclosed is that a kind of preface drives polychrome device of liquid crystals, and it comprises LCDs and be arranged at backlight 8 under the LCDs, and described LCDs is to be to show slinkingly the negative LCDs of showing that shows when not powering up.Described LCDs comprises upper substrate 1 and infrabasal plate 7, be respectively equipped with transparency electrode 2 and following transparency electrode 6 at described upper substrate 1 and infrabasal plate 7 opposite sides, be provided with alignment films 3 and following alignment films 5 on described on transparency electrode 2 and the following transparency electrode 6, alignment films 3 and following alignment films 5 are provided with the liquid crystal material 4 of apparent pellucidity when switching on described.Fig. 2 is a drive principle frame structure synoptic diagram embodiment illustrated in fig. 1.Its explanation LCDs and driving circuit thereof, the work relationship between backlight 8 and the driving circuit thereof.
In the utility model, described backlight 8 can also be located at the display screen side below except that can being located under the display screen.By light guide plate light source is led structure under the display screen.
In the utility model, described LCD can adopt the LCD of modes such as TN, VA, STN or FSTN.
Light intensity between the described backlight different colours can equate, also can be unequal, can realize showing the not purpose of various different intermediate colors to reach.For example, if adopt the light source of LED lamp as backlight, then can adopt the quantity structure of 1:1:1 not necessarily of the LED lamp of red, green and blue coloured light, realize that the light intensity between the different colours is unequal, as to adopt the quantity of the LED lamp of red, green and blue coloured light be 1:2:1, and then the background color of display is green partially.
Generally speaking, when energising, show the liquid crystal material of pellucidity, the promptly negative liquid crystal material that shows, its response speed is all slower, therefore, backlight can be shown the time at a frame, be divided into two look districts, to satisfy the normal demonstration of the slow liquid crystal material of loudness.If backlight is shown the time at a frame, be divided into three look districts, then can be when driving backlight, only selection wherein drives in two look districts simultaneously, can satisfy the normal demonstration of the slow liquid crystal material of loudness equally.
If backlight is divided into two look districts in the frame demonstration time, the then light complementation in two look districts is that the scheme of white light is better when promptly lighting simultaneously.
Described backlight can adopt LED, CCFL or OLED.
Fig. 3 is the color synoptic diagram of the utility model when adopting three look backlights.From figure as can be known, when three looks, that the LCD that preface of the present utility model drives can show is white, red, yellow, green, blue or green, blue, purple and eight kinds of states of black, has reached the basic demand of display color.
Fig. 4 is the color synoptic diagram of the utility model when adopting two look backlights, and is to be provided with two kinds of light sources of different colors in a look district therein, is red in and green putting in first look district among the figure.This mode, LCD can show Huang, white, indigo plant and four kinds of states of black.
Certainly,, can demonstrate various color, to satisfy different clients' needs by to trichromatic various combination.
The utility model is owing to when not powering up, be opaque state, and therefore in the look district that powers up, the contrast of its color and background color is obvious, is more suitable for the observation in people.
The foregoing description gives an actual example; just be used for illustrating preferred example of the present utility model; it can not be used for limiting protection domain of the present utility model, and every small change or replacement that utilizes principle of the present utility model to do all drops in the protection domain of the present utility model.
