Abstract
The invention relates to a liquid crystal terminal technology, in particular to a novel liquid crystal module light guide plate and a backlight source thereof. The invention discloses the novel liquid crystal module light guide plate and the backlight source thereof, which simplifies the manufacturing processes of the light source and reduces the cost. The invention has the technical scheme that ink mesh points doped with fluorescent powder are distributed on the novel liquid crystal module light guide plate; and a cold cathode lamp capable of emitting ultraviolet light or a light emitting diode capable of emitting blue light is used as the novel liquid crystal module backlight source. The invention can automatically regulate the proportion of the fluorescent powder in the ink mesh points according to the requirements of users for chromaticity, simplifies the manufacturing processes of the light source, reduces the cost of the light source, and is suitable for liquid crystal display terminals.
Description
Technical field
The present invention relates to the liquid crystal terminal technology, relate to a kind of novel liquid crystal module light guide plate and backlight thereof specifically.
Background technology
In the side entering type liquid crystal module of routine, the capital uses light guide plate, the printing ink site of regular distribution on traditional light guide plate is used for the bright dipping of side light inlet guiding module forward, and the CCFL (cold cathode fluorescent lamp) or the LED (light-emittingdiode) of white light sent in one use of light source.Printing ink site on the light guide plate is rounded and be evenly distributed on the light guide plate white light guiding module that directly light source is sent.And one light source (as CCFL, the LED) inside that can send white light all scribbles fluorescent powder, has also increased manufacturing process, causes this kind light source market price higher, and then increases the liquid crystal module manufacturing cost.
Summary of the invention
Technical matters to be solved by this invention is: propose a kind of novel liquid crystal module light guide plate and backlight thereof, simplify light source manufacturing process, reduce cost.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of novel liquid crystal module light guide plate, and the printing ink site that on light guide plate, distributing, described printing ink is doped with fluorescent powder in the site.
Further, fluorescent powder evenly distributes in all printing ink sites.
A kind of novel liquid crystal module group backlight source, described backlight adopts the light-emittingdiode that sends the cold cathode fluorescent lamp of ultraviolet light or send blue light.
The invention has the beneficial effects as follows: can require to allocate voluntarily fluorescent powder proportioning in the printing ink site to colourity according to the user, simplify light source manufacturing process, reduce the light source cost.
Embodiment
The invention will be further described below in conjunction with embodiment.
The present invention proposes a kind of novel liquid crystal module light guide plate, simplify light source manufacturing process, reduce cost, with respect to conventional art, main improvement of the present invention is: doping fluorescent powder in the printing ink site that distributes on traditional light guide plate, fluorescent powder has the red, green, blue three primary colours, manufacturer can carry out the color proportioning to the requirement of colourity according to the user, because having, fluorescent powder absorbs the characteristic that invisible light is converted into visible light, therefore the light source of collocation can use non-white light source, for example sends the cold cathode fluorescent lamp of ultraviolet light or sends the light-emittingdiode of blue light.So just can simplify light source manufacturing process, reduce the light source cost.
Embodiment:
Novel liquid crystal module light guide plate in this example, the printing ink site is distributing on light guide plate, described printing ink is doped with fluorescent powder in the site, fluorescent powder evenly distributes in all printing ink sites, and the backlight of arranging in pairs or groups with this light guide plate is the light-emittingdiode that sends the cold cathode fluorescent lamp of ultraviolet light or send blue light.Fluorescent powder has the red, green, blue three primary colours, and liquid crystal module shows redness if desired, then all adopts red fluorescence powder; Liquid crystal module shows green if desired, then all adopts green emitting phosphor; Liquid crystal module shows blueness if desired, then all adopts blue colour fluorescent powder; And the liquid crystal module demonstration is yellow if desired, then adopts the combination of part red fluorescence powder and part green emitting phosphor, and the yellow color depth is determined by the ratio between red fluorescence powder and the green emitting phosphor.
The present invention's technical scheme required for protection comprises but is not limited only to the foregoing description, and those skilled in the art is easy to according to foregoing description technical scheme of the present invention be changed the technique effect that reaches same slightly, and it all belongs to protection scope of the present invention.
Claims (3)
1. novel liquid crystal module light guide plate, the printing ink site that distributing on light guide plate is characterized in that: described printing ink is doped with fluorescent powder in the site.
2. a kind of novel liquid crystal module light guide plate as claimed in claim 1 is characterized in that: fluorescent powder evenly distributes in all printing ink sites.
3. novel liquid crystal module group backlight source is characterized in that: described backlight adopts the light-emittingdiode that sends the cold cathode fluorescent lamp of ultraviolet light or send blue light.
