Abstract

The utility model discloses an anti-dazzle surface cover of a display screen, which is characterized in that the anti-dazzle surface cover is stuck on the surface of a screen through adhesive; the surface cover is a glass surface cover with an outer surface provided with fine particles formed by a sand blasting method or a hydrofluoric acid etching method; when the glass surface cover is irradiated by external light, the fine particles on the outer surface of the glass surface cover can disperse reflected light, therefore, diffuse reflection is formed so as to develop anti-dazzle effect.

Description

The anti-dazzle cover of a kind of display screen

Technical field

The utility model relates to the display screen technology field, more particularly, relates to the anti-dazzle cover of a kind of display screen.

Background technology

Along with the social development scientific progress, have in the increasing people's of being deep into of electron device the life of display screen, it is shown to the show tools that reflexes to human eye on the screen again with certain e-file through specific transmission equipment.Various display screens are widely used in and show numeral, literal, the graph image that changes, and not only can be used for indoor environment and can also be used for outdoor environment, for example bank self-help cash machine ATM screen, handset touch panel, LED billboard or the like.As shown in Figure 1, all can be provided with one deck cover in the screen surface of display screen, be generally glass material, be used to protect screen.Cover is smooth transparent material, and video picture is clear.

When display screen was in photoenvironment, as shown in Figure 2, the outside surface of cover 201 was under the irradiate light effect; Direct reflection promptly takes place in the light reflected in parallel, under a certain angle; The image that is reflected into human eye changes, and makes the display screen user feel that video picture is unintelligible, and especially the user is when using touching display screen such as ATM; May cause misoperation, produce loss.

For display screen, under any circumstance easy to use, video picture is clear, becomes pursuing one's goal of increasing user.

The utility model content

For addressing the above problem, the utility model provides a kind of display screen anti-dazzle cover, to solve in the prior art the unsharp phenomenon of display screen video picture under the illumination effect.

The utility model provides a kind of display screen anti-dazzle cover, and said anti-dazzle cover is bonded in screen surface through adhesive; Said anti-dazzle cover is the glass cover that a kind of outside surface is provided with the fine particle that forms through sandblast or hydrofluoric acid etch.

Preferably, said glass cover is the tempered glass cover.

Preferably, said fine particle evenly is arranged at the glass exterior surface with the shape of rule.

Preferably, said screen module is a capacitive touch screen.

Preferably, said adhesive is an optical cement.

Can find out that from technique scheme in the utility model, the cover outside surface that will be connected with display screen is made fine particle; When extraneous light shines the glass cover; Fine particle makes light reflect back directive different angles, i.e. diffuse reflection can disperse reflection ray effectively; Be under the illumination condition at display screen and can not reach antiglare effect because of direct reflection causes video picture unintelligible.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment that put down in writing in the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is display screen and cover syndeton synoptic diagram;

Fig. 2 is existing display screen reflection ray synoptic diagram;

Fig. 3 disperses the reflection ray synoptic diagram for the anti-dazzle cover that the utility model embodiment provides.

Embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the protection domain of the utility model.

Cover and display screen syndeton synoptic diagram among the utility model embodiment one; As shown in Figure 1; Cover 101 sticks together the upper surface at display screen 102 through adhesive 103, utilizes sandblast technology that tempered glass cover 101 outside surfaces are impacted out fine particle, and fine particle becomes rule to be uniformly distributed in tempered glass cover 101 outside surfaces; Obtaining the surface has the glass cover of fine particle, like Fig. 3.Wherein, said cover 101 is specially the tempered glass cover, and said adhesive 103 is specially optical cement, and (Optically ClearAdhesive, OCA), said display screen 102 is specially capacitive touch screen.

Said sandblast technology is that a kind of pressurized air that uses carries out Treatment Technology as powered abrasive material to surface of the work, in the utility model, utilizes compressed air to promote the glass fine particle and evenly is sprayed to tempered glass cover 101 outside surfaces.

As shown in Figure 3, when irradiate light arrives tempered glass cover 301 surfaces,, be dispersed to different directions after the parallel rays reflection because cover 301 surfaces are the fine particle distribution, avoided the generation of direct reflection.

As shown in Figure 1; Cover and display screen syndeton synoptic diagram among the utility model embodiment two; Tempered glass cover 101 sticks together the upper surface at capacitive touch screen 102 through optical cement 103, utilizes the hydrofluoric acid etch technology that tempered glass cover 101 outside surfaces are eroded away fine particle, and fine particle becomes rule to be uniformly distributed in tempered glass cover 101 outside surfaces; Obtaining the surface has the glass cover of fine particle, like Fig. 3.

Said hydrofluoric acid etch technology is a kind of Wet-type etching technology, utilizes the corrosivity of hydrofluorite that the slicks of glass cap surface is gone out, and fine particle occurs.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment is conspicuous to those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and the corresponding to wide region of features of novelty.
