Pure flat structural resistance formula contact panel is to be combined for four layers by a panel (PET), a top conducting film (top), below conducting film (bottom) and a back up pad (glass or PC), wherein panel (PET) is the clear PET material, printed pattern above, by optical cement (OCA) and the upper guide electrolemma common top of forming resistive touch screen that fits together, in addition, lower guide electrolemma and back up pad also fit together by optical cement and form the bottom of resistive touch screen jointly.
The top and the bottom of pure flat structural resistance formula contact panel are when adopting the conducting film of bright characteristic, if two-layer conducting film suffer the very near a kind of optical diffraction phenomenon " Newton ring phenomenon " that then can form, can connect the generation of " the Newton ring phenomenon " that guaranteed the initial stage touch panel by air-permeable layer and outside atmosphere are set at present between top and the bottom, but this touch panel uses for a long time, also can cause the atrophy of panel air-permeable layer, thereby use for a long time, also have " Newton ring phenomenon " and take place.
The utility model content
In view of above-mentioned existing in prior technology problem, the purpose of this utility model is at the contact panel that a kind of performance and better reliability are provided, can prevent the Newton ring phenomenon of the electric resistance touch-control panel of pure flat structure, and the air-blowing mode that makes contact panel becomes more convenient, reliable and controlled, convenient is that method of operating is simple, reliably be that method is effectively secure, controlled is that the air-blowing degree can be controlled well.
In order to solve the problems of the technologies described above, the utility model embodiment provides a kind of contact panel of air-blowing structure, comprise that top surface is coated with the bottom of conducting film and the top that basal surface is coated with conducting film, the centre on described bottom and described top is provided with described top and described bottom is separated certain interval and the spaced points of subtend configuration, described insulation course is arranged on the periphery of described spaced points, described insulation course also is provided with the bleeder vent that an end is communicated with atmospheric envelope, the periphery on described bottom and described top is provided with double faced adhesive tape, double faced adhesive tape by described upper and lower periphery forms a sealant, described bleeder vent is communicated with the sealant at described spaced points place, described control panel also comprises one after described sealant air-blowing, with the sealing part of described bleeder vent sealing.
Described insulation course is combined described upper and lower by adhesive coating, and described bleeder vent passes described adhesive coating and is communicated with sealant.
Described sealing part is a silica gel.
Described top is connecting the panel of contact panel by the double faced adhesive tape on periphery top, and described bottom is connecting back up pad by the double faced adhesive tape of periphery bottom.
Implement the utility model embodiment, have following beneficial effect: contact panel is after finishing applying, utilize the top that the mode of vacuum suction will be shielded body to hold, can allow screen external body air shield body inside by bleeder vent and gas-permeable channels, this process is referred to as " air-blowing ", finishes and adopts after the air-blowing silica gel that bleeder vent is blocked.The contact panel air-blowing can prevent top and the bottom because of the back of fitting because of suffering to such an extent that too closely produce the optical effect of Newton ring.Bleeder vent utilizes silica gel to block after finishing air-blowing, can prevent that external contamination material such as airborne molecule, moisture, dust, salt from grading between the top and the bottom conductive layer that enters contact panel, thereby prevent so influence the running of lower conductive film, improve the reliability of contact panel, thereby can not have influence on the accuracy of contact panel calculating location, ensure that computational data can distortion.
Description of drawings
The structural representation of the contact panel of the air-blowing formula structure that Fig. 1 provides for the utility model embodiment;
The vertical view of the contact panel that Fig. 2 provides for the utility model embodiment.
Embodiment
Referring to Fig. 1, the structural representation of the contact panel of the air-blowing formula structure that Fig. 1 to Fig. 2 provides for the utility model, the structural improvement of the utility model contact panel, its basic structure is formed as shown in drawings:
Comprise a panel 10 (PET), one deck is coated with the top 20 of conducting film at basal surface, and one upper surface also be coated with the bottom 30 of conducting film, one back up pad 40, the centre of top and the bottom is with spaced points 50 (Dot Spacer) certain interval and the subtend configuration that will be separated from each other, utilize optics double faced adhesive tape 60 bonding between panel and the top, utilize optics double faced adhesive tape 70 bonding between bottom and the back up pad, lateral edge at conductive layer is provided with silver-colored guide passage, mark on the conducting film sees through silver-colored guide passage and is sent to soft winding displacement 90 and mark treatment circuit, this silver guide passage is arranged at the conducting film marginal surface of top and the bottom, and between silver-colored guide passage, being provided with insulation course, top and the bottom utilize adhesive coating 80 windings together.
