The large screen display system is a multi-faceted technical problem involving sound, light, and electricity that integrates multiple information reception, processing, and display, as well as various personnel operation and control. It also involves management and coordination issues with relevant departments, and is closely related to the overall structure of the display hall. It must pay attention to multimedia interactive systems, prioritize requirements, and use comprehensive integrated technologies to achieve the expected results.

Main functions：

1.information reception：

The system should not only be able to receiveVGATheRGBNetwork computer information should also be able to receive broadband voice and video signals and perform appropriate information conversion as needed.

2.Information display：

The system can publish shared information in multimedia form, and display situational, textual, tabular, and video image information in different modes and according to divided areas. Require clear and high-resolution situation display, with clear and stable text and image display.BSVLCD splicing technology has achieved system window roaming and picture in picture functions.

3.Preview, Camera, and Switching：

To ensure the accuracy and quality of projection display information, the system must have a preview function for image preview. Install cameras in the display hall to extract video images of the management and control mechanism's work. The system should have a switching display function to meet the needs of displaying multiple information channels.

4.Television and telephone conference：

The system can use monitoring, preview, switching, communication, and terminal control devices to maintain video communication with relevant parties and hold video conferences at any time.

5.Control method：

The system allows leaders, business staff, and security personnel to perform operations such as turning on and off the large screen, opening windows, selecting sources, projecting displays, adjusting audio and lighting through centralized control, mobile control, and authorization control.

6.Optimize design according to standards：

The system equipment configuration is complex, the cable signals are numerous, and the installation process and environmental conditions require high standards. Therefore, engineering wiring and equipment installation should be carried out in accordance with machine line standardization, electromagnetic compatibility standards, and large screen installation requirements to ensure the long-term stable operation of the system.

LEDDisplay screen control system：

The networked version, also known asLEDThe information release control system can control various aspects through cloud based systemsLEDTerminal.

Single machine version, also known asLEDDisplay screen controllerLEDDisplay screen control card, it is composed ofLEDThe core component of the display screen, mainly responsible for converting external video input signals or onboard multimedia files intoLEDDigital signals easily recognizable on large screens

According to the access signal method, it can be divided into synchronous system and asynchronous system：

Asynchronous control：

LEDAsynchronous control system for display screen, also known asLEDOffline control system or offline card for display screen.

Synchronous control

LEDDisplay screen synchronization control system, mainly used for real-time display of videos, graphics, notifications, etc. Mainly used for indoor or outdoor full-color large screen displays.

According to the displayed formatLEDDisplay systems are divided into three categories：

Graphic Display System、Image display screen system、Video Display Screen System

According to the control method,We divide display systems into two categories：

Communication display screen system、Real time mapping screen system

Classification based on communication methods：

Wired communication method、Wireless communication method

System Characteristics：

reliability、practicality、progressiveness、openness、economy、Maintainability、scalability、anti-interference、Ease of management、flexibility、Environmentally friendly and energy-saving type.
