Abstract
The utility model discloses a kind of insulation system of touch-screen, comprise cover-plate glass, with the capacitive touch screen of described cover-plate glass adaptation and flexible PCB, described flexible PCB is located at the correspondence position of capacitive touch screen and described cover-plate glass end, the correspondence position of described capacitive touch screen and described cover-plate glass end is bonded by OCA optical cement, elargol line on described flexible PCB and capacitive touch screen is bound by the pressing of OCA optical cement, is provided with a layer insulating outside the OCA optical cement in described flexible PCB and elargol pressing portion.The insulation system of touch-screen disclosed in the utility model is intended to reduce the short circuit of elargol, oxidation, avoids the product that therefore produces bad.
Description
[technical field]
The utility model relates to touch screen technology field, is specifically related to a kind of insulation system of touch-screen.
[background technology]
In the production of the touch-screen of prior art, after elargol silk-screen or photoetching complete, direct subsides optical cement, elargol directly contacts with optical cement, such as, adopt elargol laser etch process, some elargol dust does not have clear totally great, elargol dust is fallen in the middle of photoetching line, is then subject to thrust when putting up greatly and closing optical cement, will makes the conducting of two elargol lines, produce short circuit, cause bad; In addition, touch-screen is when applied at elevated temperature, if the cohesive of elargol and optical cement is inadequate, air just can contact with elargol and make it be oxidized, the dysfunction caused.
[summary of the invention]
For the above-mentioned defect existed in prior art, the utility model discloses a kind of insulation system of touch-screen, be intended to reduce the short circuit of elargol, oxidation, avoid the product that therefore produces bad.
The technical solution of the utility model is as follows:
A kind of insulation system of touch-screen, comprise cover-plate glass, with the capacitive touch screen of described cover-plate glass adaptation and flexible PCB, described flexible PCB is located at the correspondence position of capacitive touch screen and described cover-plate glass end, the correspondence position of described capacitive touch screen and described cover-plate glass end is bonded by OCA optical cement, elargol line on described flexible PCB and capacitive touch screen is bound by the pressing of OCA optical cement, is provided with a layer insulating outside the OCA optical cement in described flexible PCB and elargol pressing portion.
In the insulation system of touch-screen of the present utility model, a layer insulating is provided with outside the OCA optical cement in flexible PCB and elargol pressing portion, elargol line on capacitive touch screen is processed into by elargol laser etch process, in process, some elargol dust does not have clear totally great, elargol dust is fallen in the middle of elargol line, be subject to thrust when putting up greatly and closing OCA again and do use, two elargol line conductings will be made to produce short circuit to be caused bad, increase by a layer insulating and can be good at the elargol line after protecting photoetching, prevent short circuit; In addition, touch-screen is when applied at elevated temperature, and the cohesive of elargol line and OCA optical cement is inadequate, air and elargol linear contact lay can be caused, make elargol line be oxidized and cause dysfunction, increasing by a layer insulating can avoid elargol line to contact with air, avoids causing dysfunction because of the oxidation of elargol line.
[accompanying drawing explanation]
Fig. 1 is the structural representation originally seemed by new embodiment.
[embodiment]
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
As shown in Figure 1, the insulation system of touch-screen of the present utility model, comprise cover-plate glass 1, with capacitive touch screen and the flexible PCB 2 of described cover-plate glass adaptation, described flexible PCB 2 is located at the correspondence position of capacitive touch screen and described cover-plate glass 1 end, the correspondence position of described capacitive touch screen and described cover-plate glass 1 end is bonded by OCA optical cement, described flexible PCB 2 is bound by the pressing of OCA optical cement with the elargol line on capacitive touch screen, a layer insulating 3 is provided with outside the OCA optical cement in described flexible PCB and elargol pressing portion,
In the insulation system of touch-screen of the present utility model, a layer insulating 3 is provided with outside flexible PCB 2 with the OCA optical cement in elargol pressing portion, elargol line on capacitive touch screen is processed into by elargol laser etch process, in process, some elargol dust does not have clear totally great, elargol dust is fallen in the middle of elargol line, be subject to thrust when putting up greatly and closing OCA again and do use, two elargol line conductings will be made to produce short circuit to be caused bad, increase by a layer insulating and can be good at the elargol line after protecting photoetching, prevent short circuit; In addition, touch-screen is when applied at elevated temperature, and the cohesive of elargol line and OCA optical cement is inadequate, air and elargol linear contact lay can be caused, make elargol line be oxidized and cause dysfunction, increasing by a layer insulating can avoid elargol line to contact with air, avoids causing dysfunction because of the oxidation of elargol line.
Preferably, described insulation course 3 is 0.2mm with the distance of flexible PCB 2, avoid insulation course 3 too closely to cover the elargol of cover-plate glass 1 binding place with the distance of flexible PCB 2, avoid the excessive apart from the exposed space outside of elargol that makes too far away of insulation course 3 and flexible PCB 2 simultaneously;
Preferably, described insulation course 3 is not less than 1.1mm with the spacing of cover-plate glass 1, avoid insulation course 3 from cover-plate glass 1 too close to cause deaeration bad.
Above-described embodiment of the present invention, does not form limiting the scope of the present invention.Any amendment done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within claims of the present invention.
Claims (3)
1. the insulation system of a touch-screen, it is characterized in that: comprise cover-plate glass, with the capacitive touch screen of described cover-plate glass adaptation and flexible PCB, described flexible PCB is located at the correspondence position of capacitive touch screen and described cover-plate glass end, the correspondence position of described capacitive touch screen and described cover-plate glass end is bonded by OCA optical cement, elargol line on described flexible PCB and capacitive touch screen is bound by the pressing of OCA optical cement, is provided with a layer insulating outside the OCA optical cement in described flexible PCB and elargol pressing portion.
