Description
Technical field
The utility model relates to a kind of touch-screen, particularly relates to a kind of monolithic capacitive touch screen.
Background technology
Monolithic capacitive touch screen, generally comprise substrate, transparent electrode layer, perimeter circuit layer and cover layer, transparent electrode layer is arranged on the sensing region of substrate, covering layer is arranged on the neighboring area of substrate, perimeter circuit layer is arranged on to be covered on layer, cover layer and have edge step in the side near sensing region, the connecting portion of transparent electrode layer strides across edge step and is connected with perimeter circuit layer.
The connecting portion of transparent electrode layer is when striding across edge step and being connected with perimeter circuit layer, and the connecting portion of the transparent electrode layer in edge step easily ruptures because local is too thin, thus causes the stability of monolithic capacitive touch screen and reliability all lower.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of monolithic capacitive touch screen, and stability and the reliability of this monolithic capacitive touch screen are higher.The technical scheme adopted is as follows:
A kind of monolithic capacitive touch screen, comprise substrate, transparent electrode layer, perimeter circuit layer and cover layer, transparent electrode layer is arranged on the sensing region of substrate, covering layer is arranged on the neighboring area of substrate, perimeter circuit layer is arranged on to be covered on layer, covers layer and has edge step near the side of sensing region, it is characterized in that: also comprise contiguous block and extension, contiguous block is arranged on to be covered on layer and is connected with perimeter circuit layer, and extension to be arranged in edge step and to be connected with contiguous block; The connecting portion of transparent electrode layer strides across described edge step and is connected with contiguous block, and connecting portion covers on extension; Connecting portion and extension form bilayer conductive structure.
Owing to being provided with the extension be connected with contiguous block in the edge step covering layer, the connecting portion of transparent electrode layer strides across edge step when being connected with contiguous block, connecting portion covers on extension, connecting portion and extension form bilayer conductive structure, drastically reduce the area the broken string between perimeter circuit layer and transparent electrode layer like this, make the stability of monolithic capacitive touch screen and reliability higher.
As preferred version of the present utility model, described extension is made up of multiple metallic contact strips.Extension is set to multiple metallic contact strips, reduces the shade of backlight through the edge step of coverage layer.
As the further preferred version of the utility model, described metallic contact strips is needle-like tooth, and the width of metallic contact strips reduces toward transparent electrode layer gradually from covering layer.Extension is made up of the metallic contact strips of multiple needle-like tooth, and the width of metallic contact strips reduces toward transparent electrode layer gradually from covering layer, can arrange in pairs or groups mutually with the thinning gradually of edge step, shade less (backlight is through when covering the edge step of layer), even and if it is inaccurate that contraposition occurs, and also can not have influence on picture.
Compared with prior art, tool has the following advantages the utility model:
Owing to being provided with the extension be connected with contiguous block in the edge step covering layer, the connecting portion of transparent electrode layer strides across edge step when being connected with contiguous block, connecting portion covers on extension, connecting portion and extension form bilayer conductive structure, drastically reduce the area the broken string between perimeter circuit layer and transparent electrode layer like this, make the stability of monolithic capacitive touch screen and reliability higher.
Accompanying drawing explanation
