LED Technology

As in other LED - based displays, the fundamental working principle of the LED component in interactive multimedia walls relies on the electroluminescence effect of light - emitting diodes. When an electric current is applied to an LED, electrons in the semiconductor material are excited from the valence band to the conduction band. When these excited electrons return to their original energy levels, they release energy in the form of photons, resulting in the emission of light. In a color LED display, a combination of red, green, and blue (RGB) LEDs is used. By precisely controlling the intensity of the current flowing through each RGB LED, different colors and shades can be produced, enabling the display of a wide range of visual content on the LED wall.

Interactive Technologies

Touch - Screen Technology: Touch - screen technology in interactive LED display multimedia walls can be based on different principles, such as capacitive, resistive, or infrared. Capacitive touchscreens work by detecting the change in capacitance when a user's finger touches the screen. The human body is conductive, and when it comes into contact with the capacitive layer of the screen, it causes a change in the electrical field, which is then detected by the sensors. Resistive touchscreens, on the other hand, consist of two flexible layers with a thin gap between them. When pressure is applied to the screen, the two layers come into contact at the point of pressure, and the location of the touch is determined by measuring the electrical resistance. Infrared touchscreens use infrared beams that are interrupted when an object, such as a finger, touches the screen, allowing the system to detect the touch location.

Gesture Recognition: Gesture recognition technology in these walls often uses cameras and computer vision algorithms. Cameras capture the movements of the user, and the software analyzes the captured images to recognize specific gestures. For example, hand movements, body postures, or facial expressions can be used as input commands.
