Abstract
The utility model relates to a touch screen, belonging to the technical field of the information product. The touch screen comprises a PCB board and is characterized in that a PET composite membrane is jointed on the PCB board; the PET composite membrane is formed by a PET membrane and an ultra-violet protective coating; the conduction carbon adhesive layer is arranged on the joint surface of the PCB board; a conduction circuit is arranged on the copper foil of the PCB board at one side of the conduction carbon adhesive layer; a conducting material layer is arranged on the joint surface of the PET composite membrane; and a conduction circuit is correspondingly arranged at one side of the conducting material layer. For the touch screen, by adopting the PET composite membrane and arranging the conduction carbon adhesive layer on the PCB board to substitute the ITO glass, the thickness of the touch screen is greatly reduced, thereby being favorable for the requirement on super-thinness of the touch screen; moreover, the resistance of the conduction carbon adhesive layer is very homogeneous, therefore, the sensitivity, the line shape, the effective area and the like of the conduction carbon adhesive layer are obviously improved. As the PET composite membrane is jointed on the PCB board, the product surface has the advantages of high hardness, good wearing and scraping resistance, and good dirt resistance.
Description
Technical field
The utility model belongs to the information products technical field, is specially a kind of touch-screen.
Background technology
Touch-screen applications in the post office, every field such as bank, station, airport, be used to inquire about various information, easy to use, except such use, touch-screen also can with the supporting use of various computers, the mode that the user can directly write on handwriting pad with light pen without keyboard can reach the purpose to computer input information or inquiry data, has improved work efficiency greatly.But existing touch-screen, still there are some problems in its structure and performance, for example existing touch-screen adopts ito glass to make conductive film, thickness is bigger, cause the touch-screen overall volume bigger, the needs that are unfavorable for ultra-thinization of touch-screen, and adopt ito glass do conductive film have also that the inhomogeneous sensitivity that causes of resistance is low, linearity and shortcoming such as accuracy is relatively poor, systematic error is big, useful area is less.
The PET film is big owing to pulling strengrth, elastic modulus is high, impact strength is big, cold-resistant good heat resistance, electrical insulating property are good is widely used in many fields such as industry, civilian, agricultural, electron trade is higher to its requirement, require it to have higher hardness, more wear-resistant, scratch resistance is hindered, pollution resistance is stronger, and now the PET film on the market to exist hardness lower, easy to wear, easily scratch, shortcomings such as pollution resistance difference.
The utility model content
At the above-mentioned problems in the prior art, the purpose of this utility model is to design the technical scheme that a kind of touch-screen simple in structure is provided, its volume is little, highly sensitive, linearity and accuracy is better, systematic error is little, and product surface hardness height, wear-resisting, scratch-resistant, pollution resistance are good.
Described a kind of touch-screen; comprise on the pcb board; it is characterized in that applying PET composite membrane on the pcb board; the PET composite membrane is by the PET film and the ultraviolet protection coating is compound constitutes; the conductive carbon glue-line is set on the pcb board binding face; on the Copper Foil of the pcb board of conductive carbon glue-line one side the conducting wire is set, on the PET composite membrane binding face conductive material layer is set, conductive material layer one side correspondence is provided with the conducting wire.
Described a kind of touch-screen, the thickness that it is characterized in that described ultraviolet protection coating is 4～8um.
Described a kind of touch-screen is characterized in that described conductive material layer is the carbon paste rete.
Above-mentioned a kind of touch-screen adopts the PET composite membrane and conductive carbon glue-line mode is set on pcb board to replace ito glass, makes the thickness of touch-screen greatly reduce, and is very beneficial for melting the needs of touching ultra-thinization of screen; And the resistance value of conductive carbon glue-line is very even, so its sensitivity, linear and indexs such as accuracy and useful area are significantly increased than conventional touch screen.Applying PET composite membrane on the pcb board makes product surface hardness height, wear-resisting, scratch-resistant, pollution resistance good.
