LED display can also be "touchable"? Of course!

 With the development of intelligent technology, touch operation has become the most familiar interactive method in people's daily life.

Whether it is a mobile phone, tablet, or various smart terminals, people have long been accustomed to the "click and slide" control method. So the question is: Can LED display screens realize touch function?

The answer is  Of course!

Next, let's understand how LED display screens realize touch function and the technical principles behind it.

Touch screens are not just LCD screens

In everyone's impression, devices with touch function are usually various LCD screens, such as advertising machines, smart conference tablets, LCD splicing screens, etc. In fact, LED display screens can also realize touch operation nowadays, and have been widely used in multiple scenarios.

The touch function of LCD splicing screens is usually achieved by adding a capacitive touch frame and protective glass to the screen surface. The touch function of LED display screens is achieved by another way-infrared touch technology.

Touch principle of LED display screen: infrared sensing technology

The LED display screen itself has not changed, it is still a traditional LED module structure. The touch function is realized by adding a set of infrared sensing devices around the LED screen.

This set of devices consists of infrared transmitters and receivers, which are installed on the frame of the screen, forming a dense infrared detection network between them. When a finger or other object approaches or touches the screen, it will block the infrared signal at the corresponding position, and the system can accurately locate the position of the touch point, thereby realizing touch operations such as "click" and "slide".

Moreover, this touch method supports multi-touch, which can realize multiple people writing and operating at the same time, which is very suitable for scenes such as meetings, training, and presentations.

Advantages of infrared touch

Infrared LED touch screens have several obvious advantages:

No need to change the display structure: only need to add an infrared frame, no need to add a coating or controller to the screen surface, and easy installation.

Fast response speed: Since there is no capacitor charging and discharging process, the infrared touch response speed is usually faster than the capacitive type.

Strong anti-interference ability: Not affected by voltage, current, static electricity, etc., the system runs more stably.

Flexible operation mode: In addition to fingers, non-conductor objects such as pens and cards can also be used for touch, which is more free to use.

Typical application scenarios

Today, more and more users want to turn LED display screens into touch-enabled interactive platforms to meet the functional requirements of daily meetings, multimedia displays, training and teaching. Infrared touch LED screens are being widely used in the following scenarios:

Enterprise conference rooms: Replace traditional projections to improve interaction efficiency

Multimedia exhibition halls: Audiences can browse information and participate in interactions directly on the LED wall

Education and training venues: Support multi-point collaborative writing between teachers and students

Smart exhibition booths: Create a display atmosphere with a sense of technology and participation

With the continuous development and mature application of touch technology, the popularization of LED touch screens will become a general trend.

Conclusion

LED display screens are no longer just "for viewing", they can also become "interactive". Through infrared touch technology, we have made LED large screens more interactive and have stronger application value.

Whether it is a meeting, display or teaching, touching the LED screen can bring users a new experience.

In the future, as technology continues to upgrade, this highly interactive and efficient LED touch display method will increasingly enter our work and life scenes.
