Intelligent mobile terminal screen will not enter the problems such as dirt, water inlet, fuzzy display under border, simultaneously because the presence for completely covering glue-line makes this
Will not have between ITO layer and the LCD backlight layer air presence can solve the problem that touch-screen and LCD frames patch after among have air buffer
The problem of influenceing light transmittance.
The ITO layer includes glass substrate layer, above and below the glass substrate layer both sides be sequentially set with respectively ITO conductive layer,
Silver paste conductive layer and insulating oil layer of ink.
When specific implementation, fin is equipped with the LCD backlight layer top surface, the fin has bevelled inner side face,
By the bevelled inner side face on the LCD backlight layer top surface around formed an accommodating chamber, this completely cover glue-line include top glue-line and
Primer layer, the primer layer are connected to the top glue-line bottom, and the primer layer is arranged in the accommodating chamber, top glue-line edge pressure
It is located at the top of the fin.
The beneficial effects of the utility model are：The utility model this completely cover glue-line and be completely covered and completely overlay on the LCD backlight
On layer top surface, due to the lateral surface for completely covering glue-line be connected to the lateral surface of the ITO layer and the LCD backlight layer lateral surface it
Between, so being not in gap between the ITO layer and the LCD backlight layer, so as to avoid dust or steam from entering the ITO
Between layer and the LCD backlight layer and then the occurrence of influenceing display effect, the utility model is solved in complex environment, than
Such as：The problems such as intelligent mobile terminal screen will not enter dirt, water inlet, fuzzy display under the environment such as rainy day, dust be more, strong light, together
When touch can solve the problem that due to the presence that the presence for completely covering glue-line makes to have air between the ITO layer and the LCD backlight layer
Screen has the problem of air buffer influences light transmittance with middle after LCD frames patch.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation that the utility model completely covers glue-line.
Embodiment
As shown in Fig. 1 to 2, a kind of water proof and dust proof capacitance type touch control screen, it include glass cover flaggy 1, glue-line 2, ITO layer 3,
Glue-line 4 and LCD backlight layer 5 are completely covered, wherein, this completely covers glue-line 4 and is covered on the top surface of LCD backlight layer 5, and this completely covers glue-line 4
It is arranged between the ITO layer 3 and the LCD backlight layer 5.
The glue-line 2 is arranged between the glass cover flaggy 1 and the ITO layer 3.
The glass cover flaggy 1 is fixed on the top surface of ITO layer 3 by the glue-line 2, glue-line 4 is completely covered by this by the ITO
Layer 3 is fixed on the top surface of LCD backlight layer 5.
The external flexible PCB lead 6 of the ITO layer 3.
The lateral surface 41 for completely covering glue-line 4 is connected to the lateral surface 31 of the ITO layer 3 and the lateral surface 51 of the LCD backlight layer 5
Between.
This completely covers glue-line 4 and is completely covered and completely overlays on the top surface of LCD backlight layer 5 the utility model, because this completely covers glue
The lateral surface 41 of layer 4 is connected between the lateral surface 31 of the ITO layer 3 and the lateral surface 51 of the LCD backlight layer 5, so in the ITO
Be not in gap between layer 3 and the LCD backlight layer 5, so as to avoid dust or steam from entering the ITO layer 3 and carried on the back with the LCD
Between photosphere 5 and then the occurrence of influenceing display effect.
The utility model is solved in complex environment, such as：Intelligent mobile under the environment such as rainy day, dust be more, strong light
Terminal screen will not enter the problems such as dirt, water inlet, fuzzy display, simultaneously because the presence for completely covering glue-line 4 makes the ITO layer 3 with being somebody's turn to do
Will not have between LCD backlight layer 5 air presence can solve the problem that touch-screen and LCD frames patch after among have air buffer influence printing opacity
The problem of rate.
The ITO layer 3 includes glass substrate layer, above and below the glass substrate layer both sides be sequentially set with respectively ITO conductive layer,
Silver paste conductive layer and insulating oil layer of ink.
When specific implementation, fin 10 is equipped with the top surface of LCD backlight layer 5, the fin 10 has in inclination
Side 20, surrounded by the bevelled inner side face 20 on the top surface of LCD backlight layer 5 and form an accommodating chamber.
This completely covers glue-line 4 and is connected to the bottom of top glue-line 30 including top glue-line 30 and primer layer 40, the primer layer 40.
The primer layer 40 is arranged in the accommodating chamber, and the edge of top glue-line 30 is pressed on the top of fin 10.
What said structure can be achieved on when specific production, production step of the present utility model is specifically described as follows
Suddenly.
The first step, glass surface version is strengthened using the blanking of CNC monolithics, monolithic, monolithic typography makes.SENSOR functional sheets
Sliver bonding FPC again after big printing, then carries out UV glue automatic attachings with glass surface version, solidification, appearance test, and function is surveyed
Examination, posts positive and negative surface protective film.
Second step, the relative position according to touch-screen and LCD design, touch-screen and LCD pairs are made using CNC numer centres
The tool fixture that position uses, the membrane material that this for having carried out 0.25mm is completely covered to glue-line 4 are die cut down using aluminum etching cutting die
Material.
3rd step, using semi-automatic chip mounter this is completely covered into the seamless paste of glue-line 4 at the touch-screen back side；Vacuum abutted set is set
Standby parameter, 60 degree of temperature, main pressure 0.34KG, vacuum pressing-combining time 100S；LCD is placed on combined tools according to tool fixture positioning
The inside, then 45 degree of angles of left hand hold the touch-screen for having posted special transparent optical cement, down, it is release that the right hand tears glue surface to glue surface
Film, then left hand level hold touch-screen, the right hand tears LCD surface protection mould release membrance, and left hand touch-screen is determined according to tool fixture
Position is kept flat above LCD, is put into vacuum abutted equipment to the whole tool fixture of good position by having combined, starting device, is treated vacuum
Progress low temperature is gone to take off whole touch-screen+LCD module after the completion of fitting process, because LCD can not be by long-time high temperature, so
Special transparent optical cement can be used, parameter setting is 45 degree, pressure 6.5kg of temperature, and the time is 40 minutes.Outward appearance is carried out after de- light
And Function detection.
