Good use characteristics, no force required for touch, no special requirements for touch body,
Whether the touch object is hard or conductive will not affect normal use
Principle of infrared touch screen:
Generally, an outer frame is installed in front of the display screen, and there is a circuit board in the outer frame,
There are evenly arranged infrared transmitting tubes and infrared receiving tubes in the X and Y directions,
One by one corresponds to form an infrared matrix that intersects horizontally and vertically.
When touching, fingers or other objects will block the horizontal and vertical infrared rays passing through the point,
Determine the position of the touch point on the screen by the controller
electric Capacity screen 。 Capacitance Touch Panel (CTP) works by using the current induction of human body. The capacitive screen is a four layer composite glass screen. The inner surface and interlayer of the glass screen are coated with ITO (nanometer indium tin metal oxide) respectively. The outer layer is a protective layer of silica glass with a thickness of 0.0015mm. The interlayer ITO coating is used as the working surface, four corners lead out four electricity, and the inner layer ITO is used as the screen layer to ensure the working environment.
When the user touches the capacitive screen, due to the electric field of the human body, the user's fingers and the working surface form a coupling capacitance. Because the working surface is connected with high-frequency signals, the fingers absorb a very small current, which flows out from the electricity in the four corners of the screen, and the theoretical current flowing through the four electricity is proportional to the distance between the fingers and the four corners, The controller obtains the position through precise calculation of four current ratios. It can achieve 99% accuracy and has a response speed of less than 3ms.
What are the characteristics and advantages of the touch query all-in-one machine
1： Touch technology, support USB interface touch screen, support handwriting input function, and cooperate with other software to realize electronic whiteboard, drawing and other interactive functions.
2： Adjustable touch base.
3： Multi touch, support multi touch, use ten fingers at the same time, your sharp operation makes other players ashamed.
4： The design is 30 ° - 90 °, large elevation, adjustable, touch the base of the model, so that users can adjust the angle of use at will.
5： Infrared true multipoint touch screen,. Capacitive transient response.
6： Touch without drift, automatic correction, precise operation
7： Touch with fingers and soft pen.
8： High density touch point distribution: more than 10000 touch points per square inch.
9： High definition, no glass work. Low environmental requirements and high sensitivity. It is suitable for working in various environments.
10： Equipped with a high-performance infrared touch screen with a lifetime of more than one million clicks, it does not need to use a mouse or keyboard. All operations of the computer can be realized by tapping or scratching the screen with a finger, making the computer easier to use. The innovation of touch computer is that it uses multi-point touch technology, completely changing the way people interact with computers.
Touch to inquire how to purchase the all-in-one machine
1、 Housing
In terms of the shell materials of the machine, there are plastic, alloy, aluminum, sheet metal, which is a good shell material? We think it should be the material process of baking paint for sheet metal. Compared with other materials, the material of cold steel sheet metal has a good effect of corrosion and oxidation resistance on the basis of durability. Especially when hanging walls and using supports, the load-bearing property of sheet metal also has a prominent good performance.
2、 Host configuration
The host configuration needs to be guaranteed, but not the higher the configuration, the better. The host configuration of the touch all-in-one machine is the basis for ensuring the functions of the computer. Its composition and working principle are also the same as those of ordinary computers, mainly including the motherboard, CPU, memory and hard disk. When selecting the host configuration, pay attention to whether the accessories are products. In terms of specific configuration parameters, you can refer to the daily function needs to select appropriate host configuration. If there is no reference, you can consult with the relevant personnel of the manufacturer to recommend a host configuration suitable for the function to avoid blindly pursuing high configuration.
3、 LCD screen
The type of LCD screen, especially the large-sized touch screen all-in-one machine, must pay attention to the type of LCD screen, industrial LED hard screen. This type of LCD screen has a good effect in the application of touch screen equipment. On the basis of ensuring no bad spots and bright spots, it strengthens the heat dissipation and makes the LCD work more stable, There are many touch integrated machines on the market with LCD screens of different quality levels, some of which are shoddy. Attention should be paid to the type of LCD screen, and industrial LED hard screen must be selected.
The above is Xunbo Intelligent Xiaoxu's introduction to the touch query all-in-one machine. After reading this article, I believe you have a better understanding of the characteristics and advantages of the touch query machine. I hope the shopping skills introduced by Xiao Xu will help you.
