Abstract

The utility model relates to the technical field of computer peripheral equipment, in particular to an anti-peering liquid crystal display screen which comprises a shell. A backlight module, a liquid crystal display panel and a glass lens are sequentially arranged in the shell, and a light control device used for controlling light emitting angle is further arranged in the shell. By arranging the light control device in the shell, emergent light of the liquid crystal display screen is enabled to be high in same-direction performance, large divergence angle of the emergent light is avoided, and peering by others can be effectively prevented.

Description

A kind of anti-peeping LCDs
Technical field
The utility model relates to computing machine periphery peripherals technical field, specifically, relates to a kind of anti-peeping LCDs.
Background technology
Along with scientific and technological development, the application of LCDs is more and more, as smart mobile phone, palm PC IPAD, notebook computer etc.In the time using these electronic products, as login personal account number or carry out private conversation etc., do not wish that other people surround and watch or see, and the lighting angle of current LCDs is generally all larger, therefore be easy to by the people at side to peeping, bring potential risks to user, use dangerous.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of anti-peeping LCDs is provided, and the lighting angle of this LCDs is less, effectively avoids other people to peep, and uses safety coefficient high.
For achieving the above object, the technical solution adopted in the utility model is:
An anti-peeping LCDs, comprises housing, is provided with successively backlight module, display panels and glass mirror in housing, is also provided with the diaphragm for controlling lighting angle in described housing.
Further, described diaphragm comprises collector lens, and described collector lens is arranged between backlight module and display panels.
Further, described diaphragm comprises anti-peeping film, and anti-peeping film is arranged at the surface of glass mirror.
Further, described diaphragm comprises the optically focused film that is plated in glass mirror surface.
Further, described backlight module comprises light guide plate and LED module, and described LED module comprises LED lamp and circuit board, and described circuit board surface is coated with reflective membrane, between LED module and light guide plate, is provided with collector lens.
Further, described diaphragm, comprises prismatic lens and lower prismatic lens, and the fin extending direction of upper prismatic lens is vertical with the extending direction of the fin of lower prismatic lens.
The beneficial effect that the utility model is obtained is: the utility model adopts, in the housing of LCDs, diaphragm is set, make to keep good same tropism from the light of LCDs outgoing, avoid its dispersion angle larger, can effectively prevent that other people from peeping.
Brief description of the drawings
Fig. 1 is the first structural representation of the present utility model.
Fig. 2 is the second structural representation of the present utility model.
Fig. 3 is the structural representation of a kind of glass mirror of the present utility model.
Reference numeral is:
1---housing 2---glass mirror
3---display panels 4---collector lens
5---backlight module 6---anti-peeping film
21---optically focused film.
Embodiment
Below in conjunction with Fig. 1 to Fig. 3, and embodiment is described further the utility model.
Embodiment: referring to Fig. 1 to Fig. 3.
An anti-peeping LCDs, comprises housing 1, is provided with successively backlight module 5, display panels 3 and glass mirror 2 in housing 1, in described housing 1, is also provided with the diaphragm for controlling lighting angle.
By diaphragm is set, the angle of the light sending from LCDs is controlled, reduce the dispersion angle of light, make as much as possible to cast out with the direction of vertical glass mirror 2 from glass mirror 2 light out, can avoid like this peeping of other people, cause important leakage of information.
Further, as shown in Figure 1, described diaphragm comprises collector lens 4, and described collector lens 4 is arranged between backlight module 5 and display panels 3.
Due to larger from the dispersion angle of backlight module 5 light out, project light angle on display panels 3 also larger, finally cause from LCDs divergence of beam angle out larger.Therefore between backlight module 5 and display panels 3, collector lens 4 is set, can reduces to project the light angle on display panels 3.Certainly diaphragm can be also prismatic lens.Collector lens 4 can be convex lens.
Further, described diaphragm, comprises prismatic lens and lower prismatic lens, and the fin extending direction of upper prismatic lens is vertical with the extending direction of the fin of lower prismatic lens.
By two vertical prismatic lenses of fin direction are set, can adjust lighting angle preferably.
Further, as shown in Figure 2, described diaphragm comprises anti-peeping film 6, and anti-peeping film 6 is arranged at the surface of glass mirror 2.
On mobile phone, apply anti-peeping film 6 at present, therefore this can have been used on glass mirror 2, prevented that the angle of emergent light is excessive, made the angle of the light casting out by anti-peeping film 6 less.Prevent that other people from peeping.
Further, as shown in Figure 3, described diaphragm comprises the optically focused film 21 that is plated in glass mirror 2 surfaces.
Adopt to attach the mode of anti-peeping film 6 and have a lot of inconveniences, as 1, anti-peeping film 6 easily separates with glass mirror 2; 2, stop divergent rays, caused light utilization not high, need to improve the luminous power of backlight module 5.Therefore can solve these problems by optically focused film 21 is set, when design, can be according to the angle of glass mirror 2 original bright dippings, calculate the thickness distribution of the glass mirror 2 upper needed optically focused films 21 in surface, this optically focused film 21 can adjust the angle of the light that glass mirror 2 sends, light utilization is improved, realized again anti-peeping effect.
Further, described backlight module 5 comprises light guide plate and LED module, and described LED module comprises LED lamp and circuit board, and described circuit board surface is coated with reflective membrane, between LED module and light guide plate, is provided with collector lens.
In the time adopting anti-peeping film 6, some has only been blocked.Therefore can weaken certain light intensity that goes out.In order to keep certain light intensity that goes out, user can regulate increases the luminous power of backlight module 5, in order to reduce the increment of power of backlight module 5 as far as possible, is coated with reflective membrane at circuit board surface, can improve the utilization factor of light, thereby be conducive to reduce the increment of backlight module 5 power.Between LED module and light guide plate, be provided with in addition collector lens and can reduce scattering and disappearing of LED light, improve light utilization efficiency.
The utility model has been done to explain, and those of ordinary skill in the art should be appreciated that and can modify or be equal to replacement the technical solution of the utility model, and do not depart from essence and the scope of technical solutions of the utility model.
