Abstract
A liquid crystal display device, including the liquid crystal layer, include still that range upon range of setting is in light guide plate, the setting of the non - display surface of liquid crystal layer one side the white light source of light guide plate lateral wall to and range upon range of setting is in the liquid crystal layer with coloured film between the light guide plate. Because colorama is sent through white light source with the cooperation of coloured film far above the luminance of the colored light source with power, this application to white light source's luminance, under the prerequisite that does not increase the consumption, has effectively improved liquid crystal display device's luminance, simultaneously, device simple structure, low in production cost.
Description
Technical field
The utility model relates to technical field of liquid crystal display, is specifically related to a kind of vertical orientation class negativity Unicolor LCD.
Background technology
Liquid crystal indicator, be called for short LCD (LiquidCrystalDisplay), utilize the display device made by the character of liquid crystal between solid-state and liquid state, by to the liquid crystal applied voltages be arranged between two glass, changed by Liquid Crystal Molecules Alignment and tortuous change formation pattern, reflect utilizing the perspective of extraneous light and form picture.There is the advantage that volume is frivolous, radiationless, energy consumption is little.
The appearance of vertical orientation (VerticalAlignment) technology improves the accuracy of the visible angle of liquid crystal indicator, black performance, contrast and color rendition greatly, and display frame is sharper keen.Monochromatic vertical orientation liquid crystal indicator, generally by using colored backlight to make display screen show various colored font, this display scheme is by every field widespread use.
Vertical orientation class negativity monochrome shows because its display font is backlight color, therefore when backlight illumination is higher, it is more clear to show.Therefore, mainly improve colored backlight brightness by increasing LED quantity in industry, and then improve display resolution.But this design proposal not only adds raw materials cost, also increases production difficulty, and production cost is high.
Utility model content
For this reason, to be solved in the utility model is the problem that in prior art, vertical orientation class negativity Unicolor LCD production cost is high, thus provides a kind of liquid crystal indicator that effectively can reduce production cost.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of liquid crystal indicator described in the utility model, comprise liquid crystal layer, also comprise and be stackedly arranged on the light guide plate of described liquid crystal layer non-display side, be arranged on the white light source of described light guide plate sidewall and the stacked coloured film be arranged between described liquid crystal layer and described light guide plate.
The thickness of described coloured film is 1 μm ~ 1mm.
Described white light source is LED light source and/or OLED light source and/or low-pressure mercury light source.
The thickness of described light guide plate is 1mm ~ 10mm.
Described liquid crystal indicator also comprises the shell forming closed cavity with described liquid crystal layer, and described light guide plate and described coloured film are arranged in described cavity.
Described liquid crystal indicator also comprises the driven unit for driving described liquid crystal indicator.
Technique scheme of the present utility model has the following advantages compared to existing technology:
A kind of liquid crystal indicator described in the utility model, comprise liquid crystal layer, also comprise and be stackedly arranged on the light guide plate of described liquid crystal layer non-display side, the white light source of described light guide plate sidewall and the stacked coloured film be arranged between described liquid crystal layer and described light guide plate are set.Because the brightness of white light source is far above the brightness of the color light source of same power, the application to be coordinated with coloured film by white light source and sends colorama, under the prerequisite not increasing power consumption, effectively improves the brightness of described liquid crystal indicator.Meanwhile, apparatus structure is simple, production cost is low.
Accompanying drawing explanation
In order to make content of the present utility model be more likely to be clearly understood, below according to specific embodiment of the utility model also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is the LCD device structure schematic diagram described in embodiment;
In figure, Reference numeral is expressed as: 1-liquid crystal layer, 2-light guide plate, 3-coloured film, 4-white light source, 5-shell.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly, describe the described liquid crystal indicator according to the utility model embodiment in detail below in conjunction with Fig. 1.
The utility model can be implemented in many different forms, and should not be understood to be limited to embodiment set forth herein.On the contrary, provide these embodiments, make the disclosure to be thorough and complete, and design of the present utility model fully will be conveyed to those skilled in the art, the utility model will only be limited by claim.In the accompanying drawings, for clarity, the size in layer and region and relative size can be exaggerated.
Embodiment
The present embodiment provides a kind of liquid crystal indicator, as shown in Figure 1, comprise the liquid crystal layer 1 of stacked setting, coloured film 3 and light guide plate 2, described coloured film 3 is arranged on described liquid crystal layer 1 non-display side, and arranges the white light source 4 of described light guide plate 2 sidewall.
The thickness of described coloured film 3 is 1 μm ~ 1mm, can be any monochromatic or polychrome film, is selected from but is not limited to individual layer that organic and/or inorganic material formed or multi-layer compound film; As preferred embodiment of the present utility model, the coloured film 3 described in the present embodiment is monochromatic thin polymer film, and thickness is 10 μm.
Described white light source 4 is LED light source and/or OLED light source and/or low-pressure mercury light source, and the present embodiment is preferably LED light source, is the LED white chip that array is arranged.
Described light guide plate 3 is the acryl/PC sheet material of optics optical grade, and top layer is also provided with light guiding points, and thickness is 1mm ~ 10mm; The present embodiment is preferably the sheet material that thickness is 5mm.
As shown in Figure 1, described liquid crystal indicator also comprises the shell 5 forming closed cavity with described liquid crystal layer 1, and for holding, protecting the element in described liquid crystal indicator, described light guide plate 2 is arranged in described cavity with described coloured film 3.Preferably, described liquid crystal indicator also comprises the driven unit for driving described liquid crystal indicator.
Because the brightness of white light source is far above the brightness of the color light source of same power, the application to be coordinated with coloured film by white light source and sends colorama, under the prerequisite not increasing power consumption, effectively improves the brightness of described liquid crystal indicator.Meanwhile, apparatus structure is simple, production cost is low.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among protection domain of the present utility model.
