Description
Technical field
The utility model relates to a kind of touch-screen, is specifically related to a kind of sense of touch touch-screen that can the senses touch dynamics.
Background technology
Replace mouse or keyboard or button with touch-screen, must at first touch the touch-screen that is installed in the display front end with finger or other object during work, the input of selection information is located according to the icon or the menu position of finger touch by system then.Touch-screen is formed by touching detection part and touch screen controller; Touch detection part and be installed in the indicator screen front, be used to detect user touch location, send touch screen controller after the acceptance; And the main effect of touch screen controller is to receive touch information from touch point detection device, and converts it to contact coordinate, gives CPU again, and its can receive simultaneously the order that CPU sends and carry out.At present, the touch-screen applications scope has become more and more widely, and the control of the shop equipment of industrial use offers the running status of operator's field apparatus very intuitively.
Common touch-screen can only provide the positional information of two dimension, in some need detect the touch apparatus of the dynamics of pushing, just needs touch-screen that three-dimensional data are provided, such as emergency button; If can change into corresponding emergent grade, add touching intensity information in some touch recreation in addition through the detection dynamics of pushing; Its playability will strengthen greatly, still, adopt pressure detector to cooperate the way of touch-screen; Structure is too complicated again, and cost is raised again.
The utility model content
Not enough to above-mentioned prior art, the technical matters that the utility model will solve provides a kind of simple in structure, touch-screen that cost is low, and dynamics that can touch sensitive strengthens the Practical Performance of touch-screen.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is that a kind of sense of touch touch-screen comprises upper substrate, middle substrate, infrabasal plate; The lower surface of upper substrate is coated with an ITO conductive layer; The upper surface of middle substrate is coated with the 2nd ITO conductive layer, and the lower surface of middle substrate is coated with the 3rd ITO conductive layer; Be evenly distributed with the transparent dielectric support of plurality of elastic between the lower surface of upper substrate and the upper surface of middle substrate; The lower surface of infrabasal plate and middle substrate is fitted; The upper surface of infrabasal plate is provided with some depressions, and said depression equidistantly distributes, and is filled with piezoelectric material layer in the depression; The one ITO conductive layer, the 2nd ITO conductive layer, the 3rd ITO conductive layer are equipped with and are used for the electrode that is connected with sensor circuit.ITO is the abbreviation of Indium Tin Oxides, and promptly the nano indium tin metal oxide has the good electric conductivity and the transparency, can cut off harmful electron irradiation, ultraviolet ray and far infrared.When touch-screen is received pressure; Except detecting general touch point positional information,, thereby let piezoelectric material layer produce voltage because the extruding of pressure lets the depressed deformation of infrabasal plate; Again through each ITO conductive layer conduction; Thereby produce the electric signal corresponding, be used to detect the sensor circuit of electric signal, promptly can read information such as touch location and pressure in the outer connection of touch-screen with the pressure dynamics.Simple in structure being easy to realized, need not to be connected with pressure detector in addition, reduced production cost.
A kind of preferred as the utility model, said depression is inverted cone-shaped.Such structure can improve the sensitivity that signal produces, thereby improves the precision when detecting.
A kind of preferred as the utility model, said piezoelectric material layer is a piezoceramics layer.Piezoceramic material is common piezoelectric, and such structure realizes the utility model easily, and cost is low.
To sum up, the sense of touch touch-screen of the utility model can realize that the three-dimensional of touch screen touch point position, dynamics detects, and improves the Practical Performance of touch-screen, and simple in structure, and cost is low.
