Embodiment Construction

[0042] Please refer to Figure 5A, which shows 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 (group) electrodes (X1+~X3+, X1~X3-, Y1+~Y4+, Y1-~Y4-) to form this The electrodes on the touch panel 200 are invented. 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 electrode...

Abstract

The invention discloses a resistance touch panel comprising a first electrode group of a first direction which comprises a plurality of electrodes and the lengths of the electrodes are one unit or two units alternately in sequence; and the touch panel also comprises a second electrode group of the first direction which comprises a plurality of electrodes and the lengths of a plurality of electrodes are two units or one unit alternately in sequence; wherein, the two ends of a plurality of strip layers of 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. The invention aims at proposing the resistance touch panel. When the surface of the resistance touch panel 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 present invention relates to a resistive touch panel, and in particular to a resistive touch panel capable of simultaneously detecting multiple contact points and a contact point detection method thereof. 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 is shown as a side view of a known resistive touch panel when not pressed. A plurality of strip-shaped indium tin oxide (Indium Tin Oxide, ITO for short) layers 102 are formed on the surface of a transparent glass substrate 100; moreover, a plurality of strip-shaped ITO are formed on the surface of a transparent film (film) 110 layer 112; w...
