Description
Technical field
The contact panel of the utility model system relevant a kind of contact panel, particularly a kind of narrow frame.
Background technology
The function of contact panel is that the user can see through finger or pointer is carried out the function of inputting.Generally speaking, contact panel can be divided into according to method for sensing resistance-type, condenser type, acoustic wave, and the contact panel such as optical profile type.
The surf zone of general contact panel can be divided into two parts generally, and it is respectively non-visible area and visible area.In general; non-visible area be positioned at visible area around and form a frame; avoid the user when operation, directly to see the corresponding elements such as circuit that arrange in the non-visible area; usually can use atrament to cover non-visible area, so the non-visible area seen of user can be a dark border that is positioned at around the visible area.Visible area then is the part of user's institute's touch-control and operation.
1A figure shows the cut-away section schematic diagram of a traditional contact panel.For brevity, in 1A figure, only draw the subelement of traditional contact panel.Referring to 1A figure, contact panel 100 comprises a substrate 20, sequentially is formed with the shielding layer 68 that a touch-control sensing layer 28, a line layer 48, a transparent knitting layer 58, a cover plate 78, are formed at cover plate 78 peripheries on it; Described line layer 48 is formed at this substrate 78 peripheries, and is electrically connected with this touch-control sensing layer 28.1B figure shows the top view of traditional contact panel 100.Shown in 1B figure, contact panel 100 can be divided into a visible area A and a non-visible area B around visible area A, and wherein the scope of non-visible area B is by shielding layer 68 definition, and this shielding layer 68 is in order to cover this line layer 48.In fact, for preventing from seeing when contact panel 100 is inspected with a pitch angle in the top as the user line layer 48 of shielding layer 68 belows the non-visible area B, shielding layer 68 needs to push away a distance D in the relative line layer 48.And, because the distance from cover plate 78 outer ledges to line layer 48 inside edges is Z, so the general design width of the shielding layer 68 of contact panel 100 summation that is distance D and Z, namely the width of frame is the summation of D and Z.Yet,, will have greatly and benefit if can further dwindle border width (or shielding layer width) for the demand of narrow frame contact panel along with in recent years.
