Specific embodiment

Above scheme is described further below in conjunction with specific embodiment.It should be understood that these embodiments are for illustrating The utility model and be not limited to limitation the scope of the utility model.Implementation condition used in the examples can be according to specific producer Condition do further adjustment, the implementation condition being not specified is usually the condition in routine experiment.

Referring to Fig. 1, it is the structural schematic diagram of the utility model embodiment 1, provides a kind of display module structure, including by outer And the interior AR antireflective film 1 set gradually, transparent cover plate 2 and display module 6,2 inner circumferential of transparent cover plate are to apply black region 4, In It applies and is equipped with Anti-reflective coating 3 between black region 4 and transparent cover plate 2, display module 6 is fitted in the middle part of transparent cover plate 2 through optical cement 7.

In order to make display module that there is touch screen functionality, it is equipped with TP layer 5 in the lateral surface of display module 6, which is fitted in 2 inside of transparent cover plate.

AR antireflective film 1 is high refractive index medium film and low refractive index dielectric film layer for reducing the reflectivity of display screen The structure of stack of alternating, the refractive index of high refractive index medium film is 1.8~2.5, using high refractive indexes such as niobium oxide or titanium dioxide Medium is made.The refractive index of low refractive index dielectric film is 1.2~1.5, using low refractive index dielectrics such as silica or magnesium fluorides It is made.SiO is used in this example₂And Nb₂O₅It is made, plated film mode preferably uses magnetron sputtering.

Transparent cover plate 2 is transparent glass or transparent resin, is machined to suitable dimension using CNC.

Anti-reflective coating 3 is different from the refractive index of transparent cover plate 2, and refractive index is more than or less than transparent cover plate 2, and refractive index is greater than The material of transparent cover plate 2 such as MgO, TiO₂、Nb₂O₅Deng；Refractive index is less than the material such as MgF of transparent cover plate 2₂、BaF₂、AlF₃Deng； Anti-reflective coating 3 can be single-layer or multi-layer membrane structure, be high refractive index layer and low refraction when Anti-reflective coating 3 is multi-layer film structure Rate film layer alternatively layered structure, the film layer of Anti-reflective coating 3 is as the film layer structure of AR antireflective film 1, but film thickness is different.Work as light Wavelength when being λ, when light be optical path difference that d film layer back reflection is returned is half-wavelength (1/2 λ) odd-multiple by film thickness for anti-reflection Film is Anti-reflective coating when optical path difference is half-wavelength (1/2 λ) even-multiple.The refractive index of high refractive index layer is 1.7~2.6, low folding The refractive index for penetrating rate film layer is 1.1~1.4, such as first layer MgF₂, the second layer is MgO, third layer MgF₂, the 4th layer is MgO.

Painting black region 4 be black ink layer, printed by way of silk-screen printing, display module 6 be LCD screen or LCM screen.

It referring to fig. 2, is the structural schematic diagram of the utility model embodiment 2, other same as Example 1, difference exists In, AG anti-dazzling film 8 is equipped between transparent cover plate 2 and AR antireflective film 1, so that display module has the function of anti-dazzle, raising Visual effect, AG anti-dazzling film use SiO₂Etc colloidal solution be made, be made of spraying method；Or directly adopt this Just there is body AG glass made of the utilization chemical etching of anti-dazzle function to serve as cover-plate glass.

When putting out screen, ambient lighting is mapped in equipment, arrives first at AR antireflective film 1, reduces its reflection, and it is anti-then to reach AG Glare film 8, anti-dazzle influence, and the light of display area directly reaches TP layer 5 later, and the light of non-display area first passes around increasing Anti- film 3 applies black region 4 reaching.Using the characteristic of Anti-reflective coating 3, the reflectivity for applying black region 4 is properly increased, non-display area is made The reflectivity of domain and display area is more closely, put out the black display effect of screen one to improve.

Examples detailed above is only to illustrate the technical ideas and features of the present invention, and its object is to allow be familiar with technique People is can to understand the content of the utility model and implement accordingly, is not limited the protection scope of the present invention.It is all According to the spirit of the present invention substantially equivalent transformation that is done or modification, should all cover the protection scope of the utility model it It is interior.
