Abstract

A touch control panel consists of a group of upper resistance films arranged on the surface of a transparent film, a group of lower resistance films arranged on the surface of a glass base plate, a plurality of convex isolation parts provided in the resistance film area and a closed adhesive glue frame formed by coating adhesive glue nearby along the course, and therefore the two resistance films are separated by a certain gap in order to be oppositely arranged. A spilled glue blocking bands is symmetrically provided on the inner enclosure of the closed adhesive glue frame, and the insulated blocking band including at least one convex part and one concave part is formed on the surface of either or both of the upper or lower resistance film. When pressing and gluing, the concave part of the blocking band takes up the spilled glue, while the convex part blocks the spilled glue from flowing into the touch control detection area of the resistance films.

Contact panel

The utility model relates to a kind of contact panel.

Contact panel (Touch Panel) is extensively to be configured on the surfaces such as LCD (LED) or cathode ray tube (CRT), allows the user carry out the input of order whereby through the indication on the screen picture with touch-control desired locations such as finger or nibs.Common contact panel comprises that two planar resistive films separate certain interval and the subtend configuration, usually the resistive film of below is arranged on a surface with glass substrate of hard material, between two of subtend configuration, be printed on the usefulness of most planes adhesive tape as conducting and insulation, and reserve adhesion area coating viscose, whereby together with the two sealing gluing.

The upper and lower resistive film of above-mentioned subtend configuration has the circuit that can transmit the resistive film signal at upper and lower side or left and right side respectively, in order to the resistive film signal that input detects to touch-control is transferred out; And general contact panel when making along this circuit periphery coating viscose, form the mucous membrane housing of a closed, make behind the sealing gluing, make the touch-control of this resistive film detect in the zone is completely enclosed within.

As shown in Figure 6, in the above-mentioned gummed process, need to bestow pressure to sticking together the position, make it obtain the result of smooth driving fit, but in course of exerting pressure, Chang Yi causes this viscose in the irregular overflow in applying gap, so that many bad defectives of deriving, for example, the viscose of overflow will form zigzag or irregular burr in the inside edge of glueing joint line, and this not only has a strong impact on overall appearance, and reduce the value of finished product, what is more, the touch-control that directly damages resistive film detects function.

The purpose of this utility model provides a kind of contact panel, makes panel in the compression set process, can hinder but the solation that overflows and go into the touch-control of resistive film and detect the zone, so that eliminate the many unfavorable feature that the glue that overflows is produced.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of contact panel, comprise one group of top resistive film that is arranged at a flexual transparent membrane surface, one group of below resistive film that is arranged at a glass baseplate surface, in the resistive film zone, have a plurality of convex spacing bodies, and the viscose frame that is formed with a closed along near coating viscose its circuit, this two resistive film is separated and the subtend configuration with certain interval; It is characterized in that:

In closed viscose frame, enclose and be provided with the glue that overflows symmetrically and block band, blocking band is formed on the arbitrary of top resistive film or below resistive film or the surface of the two, and block to bring to and comprise a protuberance and a recess less, and recess is more to be provided with near the mode of viscose frame periphery than protuberance.

Except above-mentioned essential features, also can add following technical characterictic.

Wherein, excessive glue blocks between band and the resistive film and is electrical isolation and is provided with.

Wherein, excessive glue blocks band and is made by electrical insulator material.

Wherein, excessive glue blocks band with LINEAR CONTINUOUS and be the state of sealing and be arranged at the medial margin of viscose frame.

Wherein, in this viscose frame, enclose and the multiple tracks glue that overflows can be set block band.

By technique scheme, the utility model has been eliminated the defective of prior art, has reached above-mentioned purpose.The utility model is arranged with a tool protuberance and recess in panel amplexiforms the viscose frame of face excessive glue blocks band; make in panel compression set process; resistance to the excessive solation touch-control of going into resistive film detect the zone, thereby protected the touch-control of resistive film to detect function, have the usability on the industry.

In order to illustrate in greater detail the utility model, now enumerate specific embodiment, conjunction with figs. is described as follows:
