Embodiment 1

[0032] The variable resistance device is a sliding rheostat;

[0033] Connect the four-wire resistive touch screen to the computer with display through the four-wire resistive touch screen USB control card 3, and control the arrow pointer on the computer display by sliding the finger on the four-wire resistive touch screen;

[0034] Install the two sliding rheostats, the normally open switch 2, and the four-wire resistive touch screen USB control card 3 on the fixed base 5, and place the two sliding rheostats perpendicular to each other; the four binding posts at the lower ends of the two sliding rheostats pass the wires in the corresponding order Connect to the 4-wire resistive touch screen USB control card 3 interface. Select a binding post at the upper ends of the two sliding rheostats and connect them with the two ends of the normally open switch 2 through wires. The connection method is as attached figure 2 shown. Connect the four-wire resistive touch screen USB contro...

Embodiment 2

[0037] When the variable resistance device is composed of resistance wire 8, square slide rail 9 and insulating rod 10, resistance wire 8 is fixed on the insulating rod 10, and both sides of resistance wire 8 are connected with wire 11, as attached image 3 shown;

[0038] Connect the four-wire resistive touch screen to the computer with display through the four-wire resistive touch screen USB control card 3, and control the arrow pointer on the computer display by sliding the finger on the four-wire resistive touch screen;

[0039]Install the variable resistance device and the USB control card 3 on the fixed base, place the two insulating rods 10 perpendicular to each other on the square slide rail 9, and slide along the direction perpendicular to each other; the resistance wire 8 on the lower insulating rod 10 faces upward , the resistance wire 8 on the upper insulating rod 10 faces downward, so that when the upper insulating rod 10 is not pressed, the two resistance wires 8...

Abstract

The invention discloses a four-wire resistive touch screen working principle demonstration experiment instrument, which comprises a computer with a display screen, a four-wire resistive touch screen and a USB control card. After the four-wire resistive touch screen is connected with the computer via the USB control card, an arrow point on the computer display screen can be controlled. The four-wire resistive touch screen working principle demonstration experiment instrument also comprises a touch screen working principle simulation device. The device comprises two variable resistance devices fixed on the base. Two ends of the two variable resistance devices are correspondingly connected onto the USB control card interface via wires. After the other end of the USB control card is connected onto the computer, the arrow point on the computer display screen can also be controlled. The invention also discloses the experiment instrument demonstration method. The experiment instrument is used for carrying out learning on the working principle of the four-wire resistive touch screen, which is more intuitive and easier to understand for students, and the students can more clearly know the working principle of the four-wire resistive touch screen and the role of the ITO in the four-wire resistive touch screen played.

Description

technical field [0001] The invention belongs to the technical field of physics experiment teaching, and in particular relates to a four-wire resistive touch screen working principle demonstration experiment instrument and a demonstration method thereof. Background technique [0002] Touch screen, also known as "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. Drive various connecting devices according to pre-programmed programs, which can be used to replace mechanical button panels, and produce vivid audio-visual effects through liquid crystal display screens. As the latest computer input device, touch screen is currently the simplest, most convenient and natural way of human-computer interaction. It endows multimedia with a new look and is an attractive new multimedia interactive device. [0003] The four-wire resistive touch screen is mainly composed of a flexible top layer, a layer of ITO (indi...
