Embodiment Construction

[0047] Please refer to Figure 5A , which is a schematic diagram of the resistive touch panel of the present invention. The present invention divides the known four electrodes (X+, X-, Y+, Y-) into four groups of electrodes (X1+~X3+, X1~X3-, Y1+~Y4+, Y1-~Y4-) to form the present invention electrodes on the touch panel 200 . For example, the three electrodes of the positive X group (X+group) are the positive X-electrode (X1+), the positive X-two electrode (X2+) and the positive X-three electrode (X3+); the negative X group (X-group) The three electrodes are the negative X-electrode (X1-), the negative X-two electrode (X2-) and the negative X-three electrode (X3-); the four electrodes of the positive Y group (Y+group) are the positive Y-electrode (Y1+ ), positive Y two electrodes (Y2+), positive Y three electrodes (Y3+) and positive Y four electrodes (Y4+); the four electrodes of the negative Y group (Y-group) are negative Y one electrode (Y1-), negative Y Two electrodes (Y2-),...

Abstract

A resistance touch panel comprises a first electrode group of a first direction which comprises a plurality of electrodes; the first electrode of a plurality of electrodes is one-unit length and the last electrode is one-unit or two-unit length; while the other electrodes are two-unit length; the resistance touch panel also comprises a second electrode group of the first direction which comprisesa plurality of electrodes and the last electrode of the electrodes is one-unit or two-unit length; while the other electrodes are two-unit length; wherein, the two ends of a plurality of strip layersof the first group of the first direction are respectively connected with the first electrode group of the first direction and the second electrode group of the first direction. When the surface of the resistance touch panel of the invention is touched, a plurality of contact points can be generated simultaneously and can be successfully detected out without causing mistaken judging.

Description

technical field [0001] The invention relates to a resistive touch panel, in particular to a resistive touch panel capable of simultaneously detecting multiple contact points. Background technique [0002] With the rapid development of computer technology, touch panels are also widely used in mobile phone screens, computer screens, and personal digital assistant (PDA) screens. Basically, a touch panel can be used as an input device of a computer to replace a mouse. Currently, resistive touch panels are most commonly used in touch panels. [0003] Please refer to Figure 1A , which shows a side view of a known resistive touch panel when it is not pressed. On the surface of a transparent glass (glass) substrate 100, a plurality of strip-shaped indium tin oxide (Indium Tin Oxide, ITO for short) layers 102 are formed; moreover, on the surface of a transparent film (film) 110, a plurality of strip-shaped ITO layer 112; wherein, the strip-shaped ITO layer 102 on the transparent ...
