Abstract
The utility model relates to frame-shaped double-sided adhesive glue. The frame-shaped double-sided adhesive glue comprises a substrate, adhesive glue and release paper, wherein the adhesive glue is adhered to the two surfaces of the substrate; the release papers is covered on the surfaces of the adhesive glue; the double surfaces of the substrate are white. A liquid crystal display device comprises a liquid crystal module, a backlight module and frame-shaped double-sided adhesive glue, wherein the frame-shaped double-sided adhesive glue is used for adhering the liquid crystal module with the backlight module; the frame-shaped double-sided adhesive glue comprises the substrate and adhesive glue which is adhered to the two surfaces of the substrate, wherein the adhesive glue on the two surfaces of the substrate are adhered to the periphery of the liquid crystal module and the periphery of the backlight module, respectively; and the double surfaces of the substrate are white. The double surfaces of the substrate of the frame-shaped double-sided adhesive glue are white, so that the light radiated to the substrate of the frame-shaped double-sided adhesive glue by the liquid crystal module and the backlight module is mostly reflected back to re-enter the liquid crystal module or the backlight module. Compared with the conventional back-and-white frame-shaped double-sided adhesive glue, the frame-shaped double-sided adhesive glue of the double-sided white substrate is capable of reducing light loss, so that the display brightness of the liquid crystal display device is improved.
Description
Technical field
The utility model relates to a kind of double faced adhesive tape, particularly relates to a kind of back-shaped glue and uses the liquid crystal indicator of this back-shaped glue.
Background technology
Liquid crystal module is widely used in the numerous areas such as communication equipment (mobile phone, phone), household electrical appliance (air-conditioning), consumer electronics (MP3, electronic game machine), education electronics (e-dictionary, PDA), instrument (ammeter, volt ohm-milliammeter), tax controlling equipment (oiling machine, cashing machine).
The display part comprises liquid crystal module and backlight module.In order to guarantee the stable connection between liquid crystal module and backlight module, practices well is to utilize the black and white double faced adhesive tape that both are sticked together.Because the black and white double faced adhesive tape sticks to the periphery of liquid crystal module and backlight module, form border structure, so be also referred to as back-shaped glue.
As shown in Figure 1, it is that the back-shaped glue 10 of traditional black and white sticks on the structural representation on backlight module 11.The fine flour of the back-shaped glue 10 of black and white sticks on backlight module 11 peripheries, and the black flour of the back-shaped glue 10 of black and white is used for adhering to the periphery of liquid crystal module.
As shown in Figure 2, it is the cross section structure figure of the back-shaped glue 20 of traditional black and white.The back-shaped glue 20 of black and white comprises base material 201, adhere to the bonded adhesives 202 with 201 two surfaces of base material, and the separate-type paper 203 that covers bonded adhesives 202 surfaces.Wherein, in two surfaces of base material 201, a surface is white, and a surface is black.Use the front needs of the back-shaped glue 20 of black and white to tear separate-type paper 203.
The part light that distributes due to liquid crystal module can shine the black flour of the back-shaped glue of black and white, causes part light by the absorption of back-shaped glue, causes light loss.
The utility model content
Based on this, be necessary to provide a kind of and reduce light loss with the back-shaped glue that improves liquid crystal indicator brightness and the liquid crystal indicator that uses this back-shaped glue.
A kind of back-shaped glue, it comprises base material, be attached to the bonded adhesives on described base material two surfaces and the separate-type paper that covers described bonded adhesives surface, the two-sided white that is of described base material.
In one of them embodiment, described substrate surface material is silver.
In one of them embodiment, described bonded adhesives is the acrylic acid or the like bonded adhesives.
In one of them embodiment, described separate-type paper is the PET separate-type paper.
A kind of liquid crystal indicator, comprise liquid crystal module, backlight module and the back-shaped glue that described liquid crystal module and backlight module are sticked together, described back-shaped glue comprises base material and is attached to the bonded adhesives on two surfaces of described base material, the bonded adhesives on described base material two sides sticks to respectively the periphery of described liquid crystal module and backlight module, the two-sided white that is of described base material.
In one of them embodiment, described substrate surface material is silver.
In one of them embodiment, described bonded adhesives is the acrylic acid or the like bonded adhesives.
In one of them embodiment, described separate-type paper is the PET separate-type paper.
Be all white because the base material of back-shaped glue is two-sided, liquid crystal module and backlight module shine reflecting back that light on the base material of back-shaped glue can larger proportion, reenter liquid crystal module or backlight module, compare the back-shaped glue of traditional black and white, the back-shaped glue of two-sided white base material of the present utility model has reduced the loss of light, and then has improved the display brightness of liquid crystal indicator.
Description of drawings
It is the structural representation of the back-shaped glue of traditional black and white on backlight module for Fig. 1;
Fig. 2 is the cross section structure figure of the back-shaped glue of traditional black and white;
Fig. 3 is the cross section structure figure of the back-shaped glue of the utility model one embodiment;
Fig. 4 is the structural representation of the liquid crystal indicator of the utility model one embodiment.
Embodiment
As shown in Figure 3, it is the cross section structure figure of the back-shaped glue 30 of the utility model one embodiment.
Back-shaped glue 30 comprises two-sided white base material 301, be attached to the acrylic acid or the like bonded adhesives 302 on base material 301 two surfaces and the PET(Polyethylene Terephthalate that covers bonded adhesives 302 surfaces, poly terephthalic acid class plastics) separate-type paper 303.
In other embodiment, described base material 301 surfacings are silver.
As shown in Figure 4, it is the structural representation of liquid crystal indicator 40 of the above-mentioned back-shaped glue 30 of use of the utility model one embodiment.
The bonded adhesives on back-shaped glue 403 two sides sticks on respectively around liquid crystal module and backlight module.
Be all white because the base material 301 of back-shaped glue 30 is two-sided, liquid crystal module and backlight module shine reflecting back that light on the base material 301 of back-shaped glue 30 can larger proportion, reenter liquid crystal module or backlight module, compare the back-shaped glue of traditional black and white, the back-shaped glue 30 of two-sided white base material 301 of the present utility model has reduced the loss of light, and then has improved the display brightness of liquid crystal indicator.
Fine flour has the reflectivity of 80% left and right, relative black flour, and liquid crystal indicator can improve 5% ~ 8% overall brightness.
Silver face reflectivity is more than 95%, black flour relatively, and the overall brightness increase rate of liquid crystal indicator is larger.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
