The working principles of large LED wall display signage for conferences are based on the fundamental concepts of LED technology, digital signal processing, and electrical engineering. At the heart of the system are the LED chips, which operate on the principle of electroluminescence. When an electric current passes through the semiconductor material of the LED chip, electrons recombine with electron holes, releasing energy in the form of photons, which results in the emission of light. In an RGB (Red, Green, Blue) LED system, which is commonly used in large LED wall displays, different intensities of red, green, and blue light are combined through additive color mixing to produce a vast spectrum of colors, enabling the display of vivid and realistic images, videos, and text.

The control system plays a crucial role in the operation of the large LED wall display. It starts by receiving digital media files from various sources, such as a computer, a media server, or a live - streaming device. The media player in the control system decodes the received content, which could be in formats like MP4, PowerPoint, or PDF, and sends the video frames or image data to the video processor.

The video processor then analyzes the content and performs a series of operations to optimize its visual quality for the large display. It may scale the image to fit the resolution of the LED wall, correct any color discrepancies, and apply motion compensation techniques to smooth out any jerky movements in videos. The processed video signals are then sent to the controller, which converts the digital signals into analog electrical signals that can be used to control the individual LED chips on the panels.

The controller communicates with each LED panel, sending signals that regulate the brightness and color of each LED chip. This is achieved through a process called pulse - width modulation (PWM). PWM rapidly switches the current flowing through the LED chips on and off at a high frequency. By adjusting the duty cycle of the PWM signal, the controller can control the average current flowing through the LEDs, thereby adjusting their brightness. For example, to display a bright yellow pixel, the controller increases the duty cycle of the PWM signals for the red and green LED chips in that pixel, as yellow is a combination of red and green light in an RGB system.
