The three main types of Weiluntong touch screens are: resistive technology touch screen, surface acoustic wave technology touch screen, and capacitive technology touch screen. Each type of Veruntong touch screen has its own advantages and disadvantages, let's learn about resistive touch screens today!
The outer layer of the resistive screen is generally a soft screen, and the inner contacts are connected up and down after pressing. The inner layer is equipped with a physical material oxide metal, that is, N-type oxide semiconductor - indium tin oxide (ITO), also called indium oxide, with a light transmittance of 80%, one layer above and below, and separated in the middle. ITO is the main information used in resistive touch screen and capacitive contact screen, their working surface is ITO coating, press the outer layer with fingertips or any object, so that the surface film is concave and deformed, so that the inner two layers of ITO touch and conduct electricity so as to locate the coordinates of the pressing point to complete the control. According to the number of lead lines of the screen, it is divided into 4 lines, 5 lines and multiple lines, the threshold is low, the cost is relatively cheap, and the advantage is that it is not affected by dust, temperature and humidity. The defect is also obvious, the outer screen film is easy to scratch, and it is not possible to touch the screen with sharp objects. Generally, it cannot be multi-touch, that is, it can only support a single point, and if two or more contacts are pressed at the same time, it cannot be recognized and the exact coordinates can not be found. If you want to enlarge a picture on the resistive screen, you can only click "" many times to make the picture gradually enlarged, which is the fundamental skill principle of the resistive screen.
Control using pressure sensing. When the finger touches the screen, the two conductive layers are in contact at the point of contact, and the resistance changes. Signals are generated in both X and Y directions and then transmitted to the touchscreen controller. The controller detects this contact and calculates the orientation of (X,Y), which then works in a manner that mimics a mouse. The resistive touch screen is not afraid of dust, water and dirt, and can work in harsh environments. However, due to the use of plastic materials for the outer layer of the composite film, the explosion resistance is poor, and the service life is affected to a certain extent.
The resistive touch screen is controlled by pressure sensitivity, its surface is a layer of plastic, and the bottom layer is a layer of glass, which can withstand the interference of harsh environmental factors, but the feel and light transmittance are poor, and it is suitable for wearing gloves and occasions where you can not touch it directly with your hands.
Bright, it directly affects the visual effect of the touch screen. Transparency has the problem of the degree of transparency, infrared skills contact screen and surface acoustic contact screen are only separated by a layer of pure glass, transparency, transparency, other touch screens should be considered outstanding, other touch screens should be pondered well, "transparency", in the touch screen industry, just a very general concept, many touch screens are multi-layer composite films, only a little clear to summarize its visual effect is not good, it should contain at least four characteristics: transparency, color distortion, reflectivity and clarity, and can be divided again, For example, the degree of reflection includes the degree of mirror reflection and the degree of diffraction reflection, but the diffraction reflection on the surface of the touch screen has not yet reached the level of the CD disk, and for users, these four measures are simply enough.
Due to the existence of light transmittance and wavelength curves, the image seen through the touch screen is inevitably distorted with the original image, the static image feels only the distortion of color, the dynamic multimedia image feels not very comfortable, and the color distortion is the large color distortion in the picture, which is naturally as small as possible. The usual clarity can only be the uniform clarity in the diagram, of course, the higher the better.

A common problem with the use of Veriton touch screen - time
2.1 Why is the year display on the touchscreen 606 instead of 2006?
This is because the orientation of the high and low bytes of the words in some PLCs is not the same as that of general PLCs, such as Siemens PLC, so in this case, you only need to manually enter the 2006 year from scratch on the screen.
