For the touch all-in-one, the choice of touch mode is an important factor that needs to be considered in the user's scene use. In the industrial field, like the use scenario of multiple inverter interference in electrical room cabinets, users generally choose the capacitive touch mode of the touch all-in-one. In fact, in the field of industrial automation, the resistive touch method of the touch all-in-one is more popular with users.
Earlier, Touchmag has published related articles on the advantages of capacitive touch methods of touch display devices. Today, Touchmag will continue to work with you to discuss the advantages of using a touch all-in-one resistive touch screen.
More mature research and development
Many people know that the main feature of a capacitive touch screen is that it can realize multi-touch, allowing arbitrary selection and operation between multiple fingers, and bringing a more human experience to users. Although the multi-touch screen has made some breakthroughs in technology, the application areas of these technologies still have relatively large limitations.
Therefore, in fact, the one-touch resistive touch screen still has the largest market share. At the same time, because of the long history of research and development of resistive touch technology, its technology is already in a mature and stable period, and it is also the most widely used one in the market, with the most research.
Richer categories
The resistive touch screen can actually be said to be a sensor, as shown in the X-axis diagram of the resistive screen, it converts the physical position of the touch point (X, Y) in a rectangular area into a voltage representing the X coordinate and Y coordinate. At the same time, in terms of component classification, the resistive screen can have four-wire, five-wire, seven-wire, or eight-wire touch screens. The difference between these categories is the difference in screen bias voltage.
Among them, the most researched type of resistive touch screen is typically 4-wire resistive touch screen. Now the technology in this field has matured. The research in this field has turned to the research of core devices of resistive touch screen. The mature application device on the market is ADS7843. This is a typical chip developed for a four-wire resistive touch screen and has been widely used.

Higher resolution pixels
The application of the resistive touch screen in the touch all-in-one machine, due to its one-touch technology principle, makes the machine more accurate in touch. At the same time, in terms of pixel configuration, it can support HDMI 4K video and video transcoding, like the Touch Intelligent Intelligent All-in-One series, and the display effect is higher definition.
More suitable for harsh environments
In industrial automation application scenarios, due to the characteristics of dust, water, and oil stains in the industrial use environment, the application environment of the touch all-in-one is relatively harsh. On the screen, the resistive touch screen has the characteristics of not being affected by pollutants, and has been favored by users.
At the same time, when the resistive touch screen should be on the touch all-in-one, Touch Touch will adopt a waterproof strip design on the structure, and pass the tests of controllable humidity, high and low temperature, etc. to protect the screen from dust, water vapor and oil pollution. Can be used stably in low or high temperature environments.
More freedom to touch the media
Based on the working principle of pressure-sensitive touch screen, resistive touch screen can be controlled by any object on the touched screen. Therefore, in some industrial use scenarios that require gloves or cannot be directly touched by hand, resistance touch is generally used Touch all-in-one and supports handwriting recognition.
Lower production costs
Because the advantages of resistive touch technology have matured, resistive touch screens have become popular on screens and control systems, and the prices are relatively cheap. To a certain extent, it also saves certain manufacturing costs for touch display device manufacturers.
Write at the end
The above is summary for the main use advantages of the touch all-in-one resistive touch screen. In fact, there are still a lot of details on the use of resistive touch screens. This article will not summarize them one by one. I hope to help everyone understand the resistive touch mode of the touch all-in-one.
