The post processor 612 filters the electrical signal generated from the physical layer 611 to remove noise, processes the touch intensity and the touch position corresponding to the electrical signal corresponding to the user's touch operation, and processes the processed data into an application program. Transfer to interface 613.

The application program interface 613 receives the touch intensity and the touch position from the post processor 612 when the user touches the touch screen 500 and transmits the touch intensity and the touch position to other application software 620. Plays the role of relay.

The main touch sensor methods used in touch screens are largely divided into resistive type and capacitive type. In the resistive film method, when a touch screen is touched with a finger or a stylus pen, a contact between the upper and lower plates covered with a conductive film is conducted so that a current flows, and an input signal is generated by the voltage value at this time. The resistive film has the advantages of simpler structure, less manufacturing cost, and a stylus pen that can be used for handwriting recognition than the capacitive method.

In the capacitive method, when the static electricity generated from the finger touches the conductive film, current flow changes, and the touch screen detects the touch of the finger, generates an input signal according to the detection result, and enables multi-touch up to 2 points. It has the advantage of being able to drive a variety of touch.

In the case of the resistive type, it has a problem that it is difficult to construct various user interfaces such as multi-touch because it is a single touch type that detects only one point.In the case of the capacitive type, it is impossible to input the stylus pen, Constraints, the touch sensor cost is higher than the resistive method, and the touch screen application size is limited to less than 4.8 inches.

The present invention is configured by the touch screen disposed on the front and rear of the resistive touch sensor to enable multi-touch, and also to solve the disadvantages of the capacitive method to enable a variety of touch operations.
