touch interactive flat panel display.(1) Resistive : The pressure is connected to the upper and lower resistance networks , and the resistance distribution determines the position of the pressure point. At present, there are various combinations of four lines, five lines, six lines, seven lines, and eight lines on the market . Each type has its advantages and disadvantages , but four lines and five lines are the most popular. The principle of resistive technology is simple , the threshold is low , the integration of upstream and downstream is complete , but multi-finger detection is not possible , and the response is less sensitive , and the short life is its main disadvantage . At present , most hand-held mobile phone screens are of this type. The following table compares the different resistance types , as shown in Table ( 1 ) .
