The advantages and disadvantages of infrared and LED in different application scenarios

In the field of modern science and technology, infrared and LED technology have a wide range of applications. For the IR touch screen, it shows a unique advantage in some aspects. In the large-size touch screen application scenario, the infrared touch screen overlay can easily achieve a larger touch area, such as on some commercial display screens or large conference tablets, the infrared transmitting and receiving devices of the infrared touch screen can be flexibly arranged to adapt to different size specifications. It will not face technical bottlenecks or high costs when it comes to large size like some LED backlit touch screens.

Infrared touch screen performance features advantages

The infrared touch screen has excellent anti-interference ability. In complex light environments, such as strong light exposure or uneven light, the infrared touch screen can accurately detect the touch position through stable infrared transmission and reception, and the LED touch screen may cause inaccurate touch recognition due to light interference. In addition, the touch response speed of the infrared touch screen is fast, when the user's finger touches the surface of the infrared touch screen, its internal infrared sensing system can quickly respond, the touch signal into instructions, in contrast, some LED-related touch screens may have a certain delay, which is for some application scenarios with high interaction speed requirements. Such as video games or real-time control systems, the advantages of infrared touch screens are more obvious.

Durability and cost effectiveness of infrared touch screens

From a durability point of view, the infrared touch screen structure is relatively simple, without too many complex vulnerable parts. Taking the application of infrared touch screen in public query equipment as an example, long-term frequent touch operation will not easily damage its infrared sensing device, and some LED touch screens may cause aging and damage to backlight modules or other components due to frequent use. In terms of cost, for the demand for medium and large size touch screens, infrared touch screens are more competitive in mass production. It does not need to rely on expensive display and touch integration technology like high-end LED touch screens, which makes infrared touch screens widely used in some cost-sensitive commercial applications, such as self-service terminals, educational machines and other equipment, saving enterprises a lot of procurement and maintenance costs.

To sum up, it can not simply be said that infrared is better than LED, but under the specific application needs, infrared touch screen has significant advantages in dimensional adaptability, anti-interference, response speed, durability and cost, and has an irreplaceable position in many fields.
