Abstract
The utility model discloses a pressure-sensitive touch screen and aims to provide the pressure-sensitive touch screen which is low in cost, thin, waterproof, scratch-resistant and long in service life. The pressure-sensitive touch screen comprises a touch panel and a control device (3), which are sequentially arranged from top to bottom, wherein the touch panel is connected with the control device (3) and comprises a glass plate (4) and a plurality of pressure sensors (5); the pressure sensors (5) are distributed below the glass plate (4), and used for generating signals when a pressure is sensed and sending the signals to the control device (3); and the control device (3) is used for receiving the signals of the pressure sensors (5), calculating the position of a pressing part on the glass plate, and outputting position information. The pressure-sensitive touch screen can be widely applied to the field of touch screens.
Description
Technical field
The utility model relates to a kind of pressure sensitive touch-screen.
Background technology
Touch-screen (Touch panel) is called contact panel again, is an induction installation that can receive input signals such as touching, is transparent, generally is installed in the front of display screen.When finger had contacted on the touch-screen, its demoder can send to main frame with the positional information of touching, and just can make the program of programming in advance in the main frame make corresponding reaction; Can be in order to the push button panel of dessert machine tool formula, and produce lively visual and sound effects by liquid crystal display picture, at present; The classification of touch-screen has multiple, main use infrared-type touch-screen, resistive touch screen, capacitive touch screen etc. are arranged, the infrared-type touch-screen life-span is long; But it is thicker; Influence outward appearance, be afraid of dust, and can not accomplish waterproof; Resistive touch screen can be accomplished to prevent dust, waterproof, and that can do is thinner, but is afraid of to scratch; Capacitive touch screen can be accomplished waterproof, and that can do is thinner, but cost is very high.
The utility model content
The utility model technical matters to be solved is the deficiency that overcomes prior art, provide a kind of cost low, thin, can accomplish waterproof, not be afraid of long-life pressure sensitive touch-screen of scuffing.
The utility model comprises touch pad, the control device that sets gradually from top to bottom; Said touch pad is connected with said control device; Said touch pad comprises glass plate, several pressure transducers; Said several pressure transducers are distributed in said glass plate below everywhere, are used for when experiencing pressure, send pressure information and give said control device; Said control device is used to receive the information of said several pressure transducers, and calculates the position of position on said glass plate of exerting pressure, and positional information is exported.
Said control device comprises:
Input interface is used for the information that the input pressure sensor transmits;
CPU is used for the pressure information that receives, through calculating depressed position;
Said control device also comprises the interface circuit that can link to each other with external equipment.
The beneficial effect of the utility model is: because the utility model adopts is pressure transducer, only responsive to suitable pressure ratio, thus accomplish easily to prevent dust, waterproof, and cost low, approach, be not afraid of scuffing, long-life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model comprises touch pad, the control device 3 that sets gradually from top to bottom, and said touch pad is connected with said control device 3, and said touch pad comprises glass plate 4, several pressure transducers 5; Said several pressure transducers 5 are connected with said control device 3; Said several pressure transducers 5 are distributed in said glass plate 4 belows everywhere, are used for when experiencing pressure, produce concurrent feed signals and give said control device 3; Said control device 3 is used to receive the signal of said several pressure transducers 5; Following the tracks of the position of the said glass plate 4 of the sensor correspondence of sending signal imports as effective input position; Said control device 3 also comprises input interface, CPU, interface circuit; Said input interface is used for the information that the input pressure sensor transmits; Said CPU is used for the pressure information that receives, through calculating depressed position; Said interface circuit can link to each other with output position information with external equipment.
The utility model can be widely used in the touch-screen field.
