In the selection of touch screens, there are mainly capacitive screens, resistive touch monitor, infrared touch screens, and surface acoustic wave screens on the market. Among them, capacitive screens and resistive touchs are more popular in the market. The most direct difference between the two lies in the performance of capacitive screens. Realize multi-touch, while the resistive touch monitor is one-point touch.
Capacitive touch monitor and resistive touch monitor
Capacitive touch monitor: It is a four-layer composite glass screen. If you look from the inside to the outside, the first layer is ITO, which is used to ensure the working environment and is a shielding layer; the second layer is glass; the third layer is also ITO coating. It is used as a working surface; the fourth layer is a protective layer of silica glass. The capacitive screen works by using the current induction of the human body.
Resistive touch monitor: It has only three layers, the innermost layer is glass, the outermost layer is film, and the adjacent sides of the film and glass are coated with ITO. A resistive screen is a type of sensor.
Why is there a preference for capacitive touch monitors in the industry?
1、Multi-touch
Capacitive touch monitors respond through electrical current, and do not require pressure to generate a signal. To put it simply, the screen is divided into blocks, and a group of mutual capacitance modules are set in each area to work independently, so the capacitive screen can independently detect the touch conditions of each area, and after processing, it can realize multi-touch touch.
2. Good visual effect
Outdoors, especially under sunlight, the visual effects of the two are significantly different. Capacitive touch monitors are better and can be seen clearly in strong sunlight, but resistive touch monitors have poor visibility due to the extra screen layer reflecting sunlight.
3. Low maintenance cost
Because industrial capacitive touch monitors are often touched by fingers, the damage to the screen is very small, and the capacitive technology itself has the characteristics of wear resistance and long life, so the maintenance cost is also low when users use it, which can be said to help users save money. A lot of operating expenses.
4. Longer service life
Industrial capacitive touch monitors will last longer because the components in a capacitive touch screen don’t need to move at all. In a resistive touch screen, the upper ITO film needs to be thin enough to be elastic so that it bends down to touch the lower ITO film.
5. More responsive
The technical principle of multi-touch capacitive touch monitor, industrial touch monitor capacitive screen touch times more than 50 million times, the response time is less than 15ms, the screen error is less than 1%, the screen response similar to the sensor is more sensitive, allowing users to The experience is better.
Whether it is a capacitive touch monitor or a resistive touch monitor, both have advantages, and their maximum functions are mainly based on the field to be selected. If you have any questions about capacitive touch monitors and resistive touch monitors, you can contact Axnew.
