Which Touch Screen Is Better?
It is hard to draw the conclusions for the three touch screen. Each of them has its own advantages and disadvantages.
The infrared touch screen technology is mature, especially for large-size touch all-in-one machines (size from 32” 42” 47” 49” 55” 65” 75” 85” 98” 110” 120” 130” 150” 160”), the size over 85inch are all infrared screens.
Compared with infrared screens, the sensitivity and accuracy of capacitive screens is better, but the price is much more expensive, and can not be made too large (8” 12” 15.6” 18.5” 21.5” 32” 43” 47” 49” 55” 65” 75” 85” 86”).
Although the infrared touch screen is a little bit more mature than the nano touch, and the response is several microseconds longer than that of the nano, the life of the nano is longer than that of the infrared one.
And the products made by the nano touch can be waterproof and dustproof, Explosion proof, And lighter, many used in outdoor interactive displays.
The touch sensitivity of the capacitive touch screen is higher than that of the nano, and it is not affected by the light environment, and the products made of capacitance have higher sensitivity, stronger explosion-proof performance and more stable performance than the nano. The capacitive touch lcd display surface is flat and supports 10 points multi touch. More and more people prefer to choose the capacitive touch screen.
The infrared touch screen has grooves, the infrared frame will be a little higher than the finger write touch contact surface, the price is cheap , so the sales is the best among the three touch technology. Capacitive screen all-in-one is more beautiful, lighter and thinner. It is a flat surface, easy to achieve waterproof function, and has a more sensitive response speed. The IR’s water resistance isn’t that great.
Which screen to choose depends on the size of the interactive display, your usage scenario and budget, etc.
Capacitive touch screen interactive display
Capacitive screens work by human body current induction.
Advantages: high sensitivity, no need to press hard, good permeability
Disadvantages: high cost; in a humid and high temperature environment, it will cause the drift of the capacitive screen, resulting in inaccuracy.
The infrared screen is composed of infrared emitting led and receiving led sensing elements mounted on the outer frame of the touch screen. On the surface of the screen, an infrared detection network is formed, and any touching object can change the infrared rays on the touch screen to realize the touch screen operation.
Advantages: low price, suitable for large size, good explosion-proof performance, can be touched by any object, completely closed and maintenance-free, adaptable to harsh environments, any touching object can change the infrared rays on the contact to realize touch screen operation.
Disadvantages: poor stability, affected by light, afraid of strong light,
Which is better, infrared screen or capacitive screen?
Overall, capacitive touch screen is better than infrared screen in terms of appearance, touch feel, sensitivity or accuracy. while, infrared touch screen better with cheaper price and easier maintenance.
