Abstract
The invention relates to a double side LCD screen. All the well-known LCD screen can show the image with single side, while the double side LCD screen of the invention can achieve two side image display. The basic structure is: a light source LED or LED patch LED chips (100) is implicitly embedded into a peripheral end surface of a light conductive substrate (200), according to the size of the screen, single side end surface, double ends surface, peripheral end are embedded, the invention comprises a lighting board substrate (300), a liquid crystal matrix screen (400), a lighting material lamina (500) coated on the inner surface of the transparent lighting board substrate, luminous points (600) regularly arranged and carved or injected on the surface of the light conductive board. When the LED is charged, the illuminant LCD screen circuit controls and achieves the double side LCD screen, which can be applied to the public display imaging occasion, and belongs to the double side liquid crystal panel display technical field.
Description
Technical field
Belong to two-sided liquid crystal flat-panel display technique field.
Background technology
Known existing liquid crystal flat-panel TV has entered family, and major part has been popularized but all has been only can watch in a direction, but a lot of public arena such as megastore, station, harbour, airport etc. are if can two-sided LCD TV better.
Summary of the invention
The purpose of double-side liquid crystal display screen of the present invention provides an a kind of liquid crystal flat-panel display device and can realize two-sidedly watching TV, technique for displaying, overcomes the deficiency that a single face is watched.
Technical scheme: basic structure of the present invention is: light source adopts LED or LED paster or led chip (100), latent edge advances the peripheral end face of light guide plate substrate (200) and is bumped into according to the size of display screen periphery single end face or Double End or four end faces, and transparent plane skylight substrate (300), light guide plate both sides, two plane skylight substrates attach the former layer of lighting material (500), light guide plate surface engraving or the injection moulding that liquid crystal matrix screen (400), transparent plane skylight substrate inside surface seal be coated with outward or the luminous point (600) that is printed with the regular arrangement of lighting material is formed.Realize the double-side liquid crystal display screen of double-sided display developing when the control of light source electrified light emitting liquid crystal display circuit.
Light guide plate substrate (200) adopts transparent organic glass or plastic optical fiber plate, when light source (100) electrified light emitting, form double-sided light guide plate after (100) of said structure, (200), (300), (400), (500), (600) organic composition, constitute two-sided LCD backlight source, because backlight is a double-side, in the two-sided square rule LCDs (400) of loading onto of light guide plate, be that a cover display device circuit can be realized dull and stereotyped liquid crystal double-sided demonstration developing with circuit kit.
When light source (100) electrified light emitting, the luminous dot matrix (600) of the regular arrangement of light guide plate substrate surface is luminous, the little pointolite that these are dense, shine lighting material thin layer (500), the lighting material thin layer that optical principle that process is complicated and plane skylight substrate seal are coated with promptly forms the liquid crystal backlight of double-side to the evenly effect of diffusion of light.
Good effect of the present invention is a cover liquid crystal control circuit, and a display screen can be realized double-sided display.

(500) the lighting material thin layer that is coated with for plane skylight inside surface seal;
(600) be the luminous dot matrix of the regular arrangement of light guide plate surface engraving or injection moulding.
Embodiment
1, the substrate of light guide plate (200) adopts transparent plexiglass plate, the preparation of plastic optical fiber plate, and thickness depends on the dimension of light source that the substrate periphery end face is selected.
2, the luminous dot matrix of the regular arrangement of light guide plate substrate surface formation, a kind of mode is to adopt in the aperture technology preparation of light guide plate substrate surface with the engraving certain depth, a kind of mode is that the preparation technology with injection moulding once forms with the light guide plate substrate, and another kind of mode is to print with lighting material to form.
3, the polishing of light guide plate substrate periphery end face forms groove or hole installation light source, and sealing is accomplished in requirement, the also salable light guide plate substrate end-face of being close to attached polishing of light source, the vertical light guide plate end face of light source led or LED paster or led chip light-emitting area, light is to the light guide plate injection.
4, two of the two-sided attached subsides of light guide plate substrate plane skylight substrates adopt transparent plexiglass plate or transparent plastic sheet or the preparation of transparent plastic fibre optic plate.
5, the lighting material thin layer of plane skylight substrate inside surface is taked to print the technology that is coated with and is realized.
6, the outer two square rule LCDs that attach of plane skylight can be to the tailor-made purchase of LCDs producer.
Claims (1)
1. double-side liquid crystal display screen is characterized in that:
Basic structure by light source luminescent diode (LED) or LED paster or led chip (100) with hole or groove or be close to attached latent edge and advance the peripheral end face of light guide plate substrate (200), light guide plate substrate two sides respectively attaches a transparent plane skylight substrate (300), two plane skylight substrates attach liquid crystal square rule screen (400) outward, transparent daylighting substrate inside surface seal is coated with lighting material thin layer (500), light guide plate (100) surface engraving or injection moulding or be printed with regularly arranged luminous point (600) and form, when peripheral end face light source electrified light emitting by transparent plexiglass plate or plastic optical fiber plate, the control of liquid crystal matrix screen circuit down, form double-side liquid crystal display screen, promptly a liquid crystal display can two-sidedly watch image to show.
