At present, the development of touch screen technology shows the following trends:
1. The flexibility of the screen will be better and the clarity will be further improved
People have higher and higher requirements for touch screens, from low resolution to high resolution, from poor light transmittance to good light transmittance. United States E-Ink company has been in the "leader" position in the touch screen industry, and its research and development of electronic paper as a new touch screen material, favored by many research institutions. E-paper technology includes three aspects, namely cholesterol liquid crystal display technology, electrophoretic display technology and electrowetting display technology. The material used in e-paper is e-ink, and many microcapsules are suspended in e-ink, and the diameter of these microcapsules is about 10-4 meters wide, and the number of these microcapsules can reach 100,000 within 1 square inch. The inside of the microcapsules is made up of a mixture of dyes and pigment chips that change when they are energized. Due to the good flexibility and low power consumption of e-paper, many companies are also committed to the research and development and production of this aspect, such as Kodak, Toshiba, Motorola, Canon, Epson, Guangzhou Aoshi and so on. People have applied e-paper technology to electronic newspapers, e-books, electronic watches, and other fields [11], making users more and more aware of the portability and fun of electronic products.
2. Screen materials are evolving at a rapid pace
ITO materials are gradually being replaced by metal grids, silver nanowires, carbon nanotubes, conductive polymers, graphene, and other materials [12], among which metal grids and nano-silver wires are better than ITO's conductivity, thus providing people with more choices.
3. Multi-touch technology
Multi-touch is another development direction for touch screens. The familiar mobile phone picture can be enlarged and reduced by using two-point touch. At present, there are mainly the following kinds of multi-touch technology, Jefferson Han proposed in 2006 the suppressed total internal reflection multi-touch technology, this technology utilizes the principle of total reflection of light, the infrared light is saved in the acrylic plate, if the surface of the screen changes, the infrared light also changes, forms a touch point; Scattered light illumination multi-touch technology is developed by Microsoft, which evenly distributes light on the surface of the glass screen, and when the finger touches the screen, the light changes, so that the position of the touch point is known; Laser plane illumination, scattered light plane illumination, and LED plane multi-touch technology are three kinds of surfaces that use different light lines to form a touch screen, and their principles are similar to the first two and will not be repeated.
At present, the multi-touch screen can reach up to 500 points to be touched at the same time, which puts forward high requirements for the speed and accuracy of the processor, so it is relatively expensive. Multi-touch is widely used in schools, hospitals, and factories, and as technical barriers are broken, prices will become more and more humane.

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.
