How to Build a Touch Screen Kiosk
With the rapid advancement of technology in recent years, the Touch Screen Kiosk has evolved from a simple query business to an intelligent product integrating multiple functions. The application field has gradually spread to various industries, whether it is in a restaurant or a conference hall. , Or in large scenic spots, you can see the free touch screen kiosk display. At present, there are two touch methods for the multi touch screen kiosk in the industry. Today we will elaborate on these two touch methods for you:
The first type: capacitive sensing touch
The capacitive touch all-in-one machine uses the current induction of the human body to work. The capacitive interactive touch screen kiosk is a four-layer composite glass. The inner surface and the interlayer of the glass screen will be coated with a layer of ITO, and there is a layer of silica glass on the outside. The protective layer of the sandwich ITO layer is used as the working surface, four electrodes will be drawn on the four corners, and the inner ITO layer is the shielding layer, which is mainly to ensure the working environment. When the finger touches the metal layer, due to the human body the self-existing power forms a coupling capacitor between the user and the touch screen. For high-frequency current, the capacitor is a direct conductor, so the finger draws a small current from the contact point. This current flows from the four corners of the shielding layer. The electric power flowing through the four electrodes is proportional to the distance from the finger to the four corners. The controller obtains the specific position of the touch point through the accurate calculation of the four current ratios. Therefore, capacitive touch the surface of touch screen is very flat.
The second type: infrared touch
The display screen used by the infrared touch all-in-one machine is an infrared touch screen, which uses a densely packed infrared matrix in the X and Y directions to detect and locate the user’s touch. The infrared touch screen is actually installed with a circuit board frame in front of the display. The circuit board will arrange infrared emitting and receiving tubes around the screen, corresponding to the horizontal and vertical cross infrared matrix. When the user touches the display screen, the finger will block the two horizontal and vertical infrared electronic whiteboard lines corresponding to this position. Therefore, the position of the touch point on the screen can be judged. The infrared touch screen is a highly integrated electronic circuit integration product. At the same time, the infrared touch also includes a complete integrated control circuit, a set of high-precision, anti-interference infrared emission tubes and a set of The infrared receiving tube is installed in two opposite directions on a highly integrated circuit board to form an invisible infrared grating. The intelligent control system embedded in the control circuit continuously sends pulses to the diode to form an infrared polarized beam grid. In order to realize the infrared touch function, the infrared touch screen is generally suitable for a slightly larger 4k Floor Standing Indoor Smart Touch Kiosk, such as 49-inch, 55-inch or 65-inch.
Most commonly used touch screen kiosks types have their own advantages and disadvantages. Infrared touch screen technology is mature, especially for large-size touch all-in-one machines. The touch sensitivity and accuracy are high, easy to maintain, and the service life is very long. Compared with traditional resistive touch screens, capacitive touch screens are more sensitive and accurate. It is better, with more controllable points, but the price is slightly more expensive, and it cannot be made too large. Generally, small-sized touch screen kiosk use capacitive touch, while large-sized touch screens use infrared touch.
The host configuration of the touch screen interactive kiosk is not much different from the configuration of common computers. It is basically composed of several main sections such as motherboard, CPU, memory and hard disk. Generally, manufacturers configure and produce according to certain standards, and users can also communicate with manufacturers according to their actual needs to customize and produce correspondingly configured touch screen interactive kiosk machines.
49 inch 4K Floor Standing Interactive Touch Screen Kiosk adopts low-power, high-performance industrial-grade motherboards, strong CPU performance, quad-core processor, and deeply optimized Android intelligent system, which can run various applications smoothly; at the same time, built-in EZTOUCH interactive content production The software supports multiple simultaneous remote publishing and management.
