Abstract

Display screen that is a kind of dust-proof and preventing brandreth from loosening, including backlight and the display module being set in backlight, backlight is provided with center, and center is also enclosed equipped with brandreth, and brandreth one end is overlapped in display module edge；Under traditional display screen structure, brandreth and center and the contact surface of display module can be arranged single side bubble cotton and carry out seal clearance, prevent dust from entering, fixed brandreth simultaneously, but part-structure gap is relatively narrow, single side bubble cotton can not be arranged in position no more than 0.1mm, and dust and salt fog are easy to enter from there, and corrosion foam causes brandreth to loosen.The utility model substitutes single side bubble cotton using double-sided adhesive, and double-sided adhesive is relatively thin, can seal the gap no more than 0.1mm, secondly, brandreth and center are fixed by snap, even if double-sided adhesive loses viscosity, brandreth and center are also able to cooperate closely, will not loosen.

Description

Display screen that is a kind of dust-proof and preventing brandreth from loosening

Technical field

The utility model relates to display screen technology fields, more particularly to display screen that is a kind of dust-proof and preventing brandreth from loosening.

Background technique

Important medium of the display screen as man-machine information interaction, is applied in the environment to become increasingly complex, traditional Display screen structure can be arranged single side bubble cotton and carry out seal clearance between brandreth and center, display module, come prevent dust salt fog into Enter, while fixed brandreth, but since part-structure clearance requirement is relatively narrow, single side bubble cotton structure is thicker, the position no more than 0.1mm Single side bubble cotton can not be arranged by setting, and dust and salt fog are easy to enter from there, influence display effect, the corrosion of salt fog leads to foam Viscosity reduces, and causes brandreth to loosen, seriously affects the usage experience and service life of product.

Utility model content

It can not be filled for above-mentioned traditional display screen structure division gap is narrow, caused dust enters and salt air corrosion The problem of, the utility model proposes display screens that is a kind of dust-proof and preventing brandreth from loosening.

Display screen that is a kind of dust-proof and preventing brandreth from loosening, including backlight and the display module being set in backlight, institute Backlight is stated to enclose equipped with brandreth；

Further, the brandreth is integrally in back-shaped, encloses in the brandreth and is overlapped in display module edge；The brandreth Gap between backlight and display module, is additionally provided with double-sided adhesive；The double-sided adhesive structure is relatively thin, can fill less In the gap of 0.1mm, so that gap is adequately sealed, salt fog and dust is effectively prevent to enter, while fixed brandreth.

Further, the brandreth includes back-shaped ontology and the flanging for being set to back-shaped ontology periphery, and whole is in inverted L-shaped Binding structure.

Further, the backlight is provided with center, and the back-shaped ontology is set to center top, the back-shaped ontology Inside enclose the edge for being overlapped in display module.

Further, the double-sided adhesive is set to the contact surface of back-shaped ontology and center top, display module edge, filling The gap of each inter-module, prevents dust from entering, while fixed brandreth.

Further, the flanging is wrapped in center lateral surface, the center and the flanging by the way that multiple buckles are arranged It connects and fixes, even if double-sided adhesive loses viscosity, brandreth and center are also able to cooperate closely, will not loosen, while lengthening extraneous dust The path length entered with salt fog extends display screen service life.

Further, four corner locations of the flanging are provided with opening, convenient for the clamping of the buckle of center and brandreth.

Further, an at least side edgefold is provided with inside arc convex, close to its apical position convenient for brandreth Assembling.

The utility model bring the utility model has the advantages that

1, one kind of the utility model design is dust-proof and prevents the display screen of brandreth loosening, will be traditionally used for sealing seam Gap pastes the single side bubble cotton of fixed brandreth, is improved to the thinner double-sided adhesive of thickness, so that being not more than the gap of 0.1mm It can adequately be filled, effectively prevent the entrance of dust and the corrosion of salt fog；

2, one kind of the utility model design is dust-proof and the display screen that prevents brandreth from loosening, in the center and brandreth of backlight Flanging setting buckle, even if double-sided adhesive loses viscosity, the brandreth and center are also able to cooperate closely, are not easy to loosen, lengthen simultaneously The path length that extraneous dust and salt fog enter, can effectively extend display screen service life.

Specific embodiment

Preferred embodiments of the present invention are described below, those of ordinary skill in the art will be according to described below It is realized with the relevant technologies of this field, and can be more clearly understood that the innovation and bring benefit of the utility model.

With reference to Fig. 1 and Fig. 2, a kind of dust-proof and display screen that prevents brandreth from loosening, including backlight 10 and it is set to backlight Display module 20 on 10, the backlight 10 are enclosed equipped with brandreth 30；The brandreth 30 is whole in back-shaped, the brandreth 30 it is interior It encloses and is overlapped in 20 edge of display module；Gap between the brandreth 30 and backlight 10 and display module 20, also sets up There is double-sided adhesive 40；40 structure of double-sided adhesive is relatively thin, can fill the gap no more than 0.1mm, so that gap obtains adequately Sealing effectively prevent salt fog and dust to enter, while fixed brandreth 30.

As shown in Fig. 3,4,5,6, the brandreth 30 includes back-shaped ontology 31 and the folding for being set to back-shaped 31 periphery of ontology Side 32 is generally in the binding structure of inverted L-shaped, and the backlight 10 is provided with center 11, and the back-shaped ontology 31 is set to center 11 tops, the interior of the back-shaped ontology 31 enclose the edge for being overlapped in display module 20.

The double-sided adhesive 40 is set to the contact surface of back-shaped ontology 31 and 11 top of center, 20 edge of display module, filling The mistake narrow gap of each inter-module, prevents dust from entering, while fixed brandreth 30.

Preferably, in the gap for enclosing side in the back-shaped ontology 31, filled with transparent anticorrosion gel 50, position herein Set it is direct contacted with extraneous, the setting of the anticorrosion gel 50, while filling gap, pre- salt spray proof sweat stain enters corrosion Double-sided adhesive 40 causes the viscosity of double-sided adhesive 40 to reduce, and brandreth 30 falls off.

The flanging 32 is wrapped in 11 lateral surface of center, in 11 lateral surface of center and the medial surface of flanging 32, hands over For 33 structures of buckle are provided with, even if double-sided adhesive 40 loses viscosity, the brandreth 30 is also able to cooperate closely with center 11, adds simultaneously The path length that long external world's dust and salt fog enter, extends display screen service life.

Further, the flanging 32 is provided with opening 34 in the corner location of brandreth 30, but not limited to this so that iron Frame 30 is easier to be clamped.

Preferably, the flanging 32 of 30 downside of brandreth is provided with inside arc convex 35 close to its apical position, but It is not limited to this, convenient for the assembling of brandreth.

It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined Assert that specific embodiment of the present utility model is only limited to these instructions.For the common of the utility model technical field For technical staff, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, all answers When being considered as belonging to the protection scope of the utility model.
