Applied in the electronic equipments such as mobile phone, computer, e-book, tablet personal computer, it has also become essential part in people's life.With
It is various can the numerous and confused of display device of touch-control emerge, consumer is to touching the requirements of each side such as the attractive in appearance of screen, performance
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
Belong to lead by membrane electrode with the top of the contact panel or the flexible PCB of bottom is bound and connected, realize flexible PCB with
The electrical connection of membrane electrode, and in order to display device overall appearance effect, it is necessary in the top of glass cover-plate or bottom pair
The position process black light shield layer of flexible PCB is answered to cover metal lead wire and flexible PCB, due to metal lead wire with it is flexible
Size of the lap-joint of circuit board on the length direction of contact panel is larger, increases the size of flexible PCB, causes soft
Property circuit board area coverage on the length direction of contact panel it is larger, the corresponding size for increasing black light shield layer, so as to shadow
The size of viewing area has been rung, the screen accounting of display device has been reduced, significantly reduces Consumer's Experience.
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
The problem of top of contact panel or bottom frame are wider, and viewing area is smaller, and screen accounting is relatively low, and Consumer's Experience is poor.
In order to solve the above technical problems, the present invention provides a kind of contact panel, the contact panel include flexible PCB,
First electrode and conductive lead wire, the flexible PCB are located at one end of the length direction of the contact panel, and are electrically connected to
The mainboard of display device, the flexible PCB are provided with the first binding point, and first binding point includes at least one first long side,
The width extension of contact panel described in the first long edge, the first electrode are electrically connected to by the conductive lead wire
First binding point, so as to be electrically connected to the flexible PCB.In this way, the first binding point includes at least the first long side, institute
The width for stating contact panel described in the first long edge is extended, and avoids the first binding point by the first long edge touch surface
