Embodiment
Below, with reference to the accompanying drawings, the preferred embodiment of the LCD with newtons ring prevention function among the present invention is described.In this process, also conveniently describe for clear and definite, the fineness degree of the line that illustrates or the size of textural element etc. may be by the exaggeration diagrams.And, term described later is to consider the function that plays in the present invention and the term that defines, they can be according to user, application person's intention or convention and therefore difference, should be that the basis defines with the content in the whole instructions of the present invention for above-mentioned term.
And, following embodiment is intended to limit interest field of the present invention, it is the exemplary content as the textural element of pointing out out in the interest field of the present invention, be contained in the technological thought that embodies in the instructions of the present invention, and include the embodiment that in the textural element of interest field, can be used as the textural element that equipollent replaces and to belong in the interest field of the present invention.
Embodiment
Fig. 1 is the exploded view of the LCD with newtons ring prevention function in one embodiment of the invention; Fig. 2 is the partial plan for the wiring layout among Fig. 1; Fig. 3 is the planimetric map that is provided with filtrator in Fig. 2.
As shown in Figure 1, include back light unit 100, LCD panel 110, photo-shield strip 120, framework 130 and form 140 among the LCD with newtons ring prevention function of one embodiment of the invention.
Wherein, in back light unit 100, include reflection thin plate 101, light guide plate 102, optical sheet 103 and light source 104.At this, to use LED (light emitting diode) as above-mentioned light source 104, in addition, LCD panel 110 will be installed on the top of back light unit 100, the liquid crystal material of LCD panel 110 will be made a response to the light source 104 of back light unit 100, and the signal corresponding character of output and input or picture etc.
At this moment, photo-shield strip 120 will be close between back light unit 100 and the LCD panel 110, and cut off the leakage of light.Wherein, the morphosis of photo-shield strip 120 to coat bonding agent 121 in the two sides of tygon film, LCD panel 110 and back light unit 100 will be pasted on the bonding agent 121 of photo-shield strip 120.Under the effect of the tygon film that inserts in photo-shield strip 120, the light of back light unit 100 can't leak to the outer side of LCD panel 110.
In addition, framework 130 will be provided for placing the space of back light unit 100 and LCD panel 110, and in the inboard fixedly back light unit 100 and LCD panel 110, and protect.At this, can use metal material as said frame 130.
In addition, in LCD panel 110, form 140 is installed on the top of framework 130, and is separated by about 1.0mm with LCD panel 110.And above-mentioned form 140 is made by acryl resin, and is made into the thickness about 1.5mm.At this, form 140 will be installed on the inboard of the form 140 of the upper edge angle part that constitutes said frame 130.
With reference to Fig. 2, in form 140, be formed with the opening 141 that connects the gap between form 140 and the LCD panel 110, at this, opening 141 will allow air to flow between form 140 and the LCD panel 110, thereby will prevent that form 140 is close to the phenomenon of LCD panel 110.Promptly, owing to causing the inner air between form 140 and the LCD panel 110 to shrink in the rapid temperature variation that is subjected to from high temperature to low temperature, and the influence of the impact that applies from the outside, form 140 will be to LCD panel 110 lateral bending songs, and may be close to LCD panel 110, therefore, the opening 141 by above-mentioned form 140 allows air to flow into, thereby can prevent that form 140 is close to the phenomenon of LCD panel 110.
At this, opening 141 will be formed at the corner location of form 140, from form 140 will be difficult in appearance discern, thereby under the situation of the outward appearance that does not influence form 140, be arranged in the form 140.And opening 141 is formed at a plurality of positions of form 140, and a plurality of parts between form 140 and LCD panel 110 allow air to flow into, thereby can effectively prevent the situation that form 140 and LCD panel 110 are close to.And opening 141 is with the big or small small formation of the diameter of 1.0mm, thereby is not easy to be found by naked eyes, can allow air to flow into the inboard of form 140 simultaneously.
With reference to Fig. 2 and Fig. 3, in opening 141, be provided with filtrator 142, above-mentioned filtrator 142 is used to prevent enter moisture between form 140 and the LCD panel 110, thereby can prevent between form 140 and the LCD panel 110 dewfall takes place and the phenomenon that causes fuzzy pictures.
At this, filtrator 142 is to have the film that is used to cut off the scale that moisture passes through, and can provide on the scale of above-mentioned film and only allow the structures such as non-return valve of air to the interior side inflow of form 140.
As mentioned above, in the form 140 of the picture that constitutes LCD panel 110, to allow air to flow into by the opening 141 that is formed at form 140 between LCD panel 110 and the form 140, the interval that makes form 140 keep 1.0mm for LCD panel 110, and, by keeping the interval between form 140 and the LCD panel 110, can simply prevent the generation of the Newton ring that form 140 and LCD panel 110 are close to.
The present invention is illustrated according to embodiment, should be appreciated that the foregoing description does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within protection scope of the present invention.
