More and more higher.Capacitive touch screen is a kind of touch-control structure for being widely used in display device, the condenser type of external hanging type structure
Touch-screen is mainly GF (Glass-Film) structures or GFF (Glass-Film-Film) structure, i.e. glass cover-plate-membrane electrode
Structure or glass cover-plate-membrane electrode-membrane electrode structure, and membrane electrode need with positioned at contact panel one end
Flexible PCB (Flexible Printed Circuit, FPC) is bound, so as to realize other electronic devices with display device
Electrical connection.
In the prior art, the center section of contact panel is viewing area, and the edge of viewing area passes through opaque gold
Category lead by membrane electrode with the top of the contact panel or the flexible PCB binding of bottom is connected, realize flexible PCB and
The electrical connection of membrane electrode, then by flexible PCB around rolling over and be connected on display panel.But flexible PCB cost is higher,
And the binding procedure of flexible PCB and contact panel is complicated, so as to cause the production cost of contact panel high.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of contact panel and display device, to solve in the prior art
Flexible PCB cost is higher, and the binding procedure of flexible PCB and contact panel is complicated, so as to cause contact panel
The problem of production cost is high.
In order to solve the above technical problems, the present invention provides a kind of contact panel, display panel, the contact panel are electrically connected
Including nesa coating, the nesa coating includes main part and extension, and the extension is flexibly connected in the main body
One end margin in portion, the main part is stacked with the display panel, and the relatively described main part bending of the extension is simultaneously
The side surface that the display panel deviates from the main part is fixedly connected with, the main part is provided with touch control electrode, the extension
Portion is provided with binding point, and the main part and the extension are equipped with conductive lead wire and tied up with electrically connecting the touch control electrode with described
Fixed point, the binding point electrically connects the display panel, so that the touch control electrode is electrically connected to the display panel.It is flexible
Extension bending after can connect main part and display panel respectively, so that contact panel is electrically connected into display panel, extend
Portion is also to be made to be formed by transparent conductive material as a part for transparent conductive film, and the cost of material is low, and electric conductivity
Good, processing technology thereof is simply easily realized, instead of the higher flexible circuit of the cost of electrical connection contact panel and display panel
Plate, so as to reduce the production cost of contact panel.
Further, the extension include bending end and fixing end, the bending end be flexibly connected in the fixing end with
Between the main part, the fixing end is bent by the relatively described main part of the bending end and is fixedly connected with the display surface
Plate, the size of the bending end is less than the size of the fixing end.The bending flexibility of bending end can be so improved, is conducive to carrying
The flexibility of extension is risen, the connection of mainboard and contact panel is more flexible.
Further, the conductive lead wire includes the first conductive lead wire and the second conductive lead wire, and each first conduction is drawn
Line correspondence one second conductive lead wire of electrical connection, first conductive lead wire is located at the edge of the touch control electrode, and will
One of two ends of the touch control electrode are electrically connected to second conductive lead wire, and second conductive lead wire is located at the extension
