Whether to use an infrared screen or a capacitive screen, this problem is not absolutely good or bad, because the working principle and composition of infrared screens and capacitive screens are different. With the development of the times and technological changes and advancements, touch screens are constantly updated and improved.
Let's briefly talk about the main differences between infrared screens and capacitive screens, as well as their working principles and advantages.
1. The infrared screen is composed of an infrared emitting lamp tube and a receiving sensor lamp tube mounted on the outer frame of the touch screen. On the surface of the screen, an infrared detection network is formed. Any touched object can change the infrared rays on the contacts to realize the touch screen operation.
Advantages: low price, suitable for large size, can be spliced up to 300 inches, can be used with splicing screen without glass, good explosion-proof performance, can be used for anti-glare and light resistance, waterproof, can be touched by any object, completely closed and maintenance-free , Adapt to harsh environments, the number of touch points can be selected arbitrarily.
Disadvantages: The infrared screen has a recessed touch screen and the screen is not flat, which will slightly affect the overall aesthetics.
2. Capacitive screens mainly rely on human body current induction to work
Advantages: The current price is slightly higher than the infrared screen, the touch sensitivity is high, no pressing is required, the permeability is good, the resolution is high, the flat surface, the anti-glare, the waterproof, the capacitive touch all-in-one flat screen display is more beautiful.
Disadvantages: limited size. The current maximum size is 65 inches.
From a comprehensive comparison, the infrared screen capacitive screen has its own advantages and disadvantages. The choice depends mainly on actual needs. You can also find the manufacturer to recommend it. After all, this line is also more professional. The infrared on the left and the capacitor on the right are shown in the figure below. The next effect is more in my heart when choosing a touch all-in-one machine.
