DID LCD splicing display curtain wall system

Overview of System Design
preface
With the rapid development of automation and information technology, monitoring centers have increasingly high requirements for information display. The large screen display system, as a communication platform for centralized information display, can display various computer graphics, text information, and video signals of monitoring systems in a centralized manner, playing an important role in real-time scheduling, consultation, decision-making, and information feedback.
In order to meet the requirements of centralized information display in the monitoring center, it is necessary to establish a large screen display system. And there are the following requirements:
1) High reliability, high safety, flexible operation, and easy integration
The system should adopt advanced technology and system architecture to improve system reliability and safety, and reduce the impact of failures; Adopting a unified control management software allows for flexible operation
2) The image display effect is clear and stable
The image display effect is delicate and clear, the screen brightness is high, the display is uniform, the color reproduction is realistic, the image distortion is small, the display stability is high, the service life is long, and it can meet the requirements of long-term continuous display for 7 × 24 hours.
3) Access capability of various display signals
Capable of displaying computer image signals of mainstream operating systems such as Windows, UNIX, Linux, and displaying various videos such as PAL/NTSC/1080p/1080i/720p, as well as RGB/HV, DVI, and other signals.
4) Unified display and functional partition display
The entire display system can serve as a unified display platform to display various signals on the entire screen, such as displaying welcome messages. At the same time, it can be divided into multiple functional areas, each of which will display various signals according to functional needs.
5) High resolution graphic display
The entire display system can provide a high-resolution unified display platform, capable of displaying high-resolution graphics.
Based on the above requirements and the customer's own needs, we provide a liquid crystal splicing large screen display system solution to the customer. This solution integrates the simplest splicing technology, multi screen image processing technology, and signal switching technology into one, forming a large screen display system with high brightness, high definition, high intelligence control, and advanced operation methods.
Through this LCD large screen display system, comprehensive display of system computer images and video image information can be achieved, forming a fully functional and technologically advanced information publishing and display management control system. The entire system can be connected to computer systems, video surveillance systems, and other independent computer workstations to achieve comprehensive display of computer graphics and video image information.
2. System availability
Based on the customer's requirements for the system scale and application of the large screen display system, we will select suitable products in the system to meet the application needs of the large screen display system. By utilizing the built-in image processing system of LCD and signal switching, any signal can be selected for display in any unit area; Realize the image stitching of a large screen display system into full screen or single screen display.
3. System progressiveness
As the display unit of the large screen display system, DID LCD screen can directly input RGB and Video signals, and can also be used with signal switching to achieve simultaneous input of multiple signals, and can freely select one signal to display on any single screen of the large screen. RS232 control software not only has powerful display control functions and a simple and intuitive operation interface, but also has a unique image stitching automatic correction function.
To meet the requirements of various large-scale display center applications, the large screen display system used should not only have excellent display characteristics such as high brightness, contrast, high resolution, wide viewing angle, brightness and color uniformity, but also have the ability to operate continuously, safely and stably for a long time. At the same time, to reduce the waste of funds and time in daily maintenance and repair, the display system should meet the requirements of "easy maintenance and no consumables".
Our company's LCD splicing large screen display system adopts the "narrow edge" LCD display manufactured by SAMSUNG's unique technology and advanced process in South Korea. It is composed of a 2CM LCD display screen in the middle through a 1CM frame splicing, with excellent display quality. At the same time, the fully digital and highly integrated circuit design ensures system stability.
Our LCD products have passed CE and CCC certifications, with an average time between failures of over 50000 hours and a core component lifespan of over 50000 hours, demonstrating extremely high reliability.
4. System reliability
Being able to meet the requirements of practical work to the maximum extent possible, considering the satisfaction of user business management as the first element, and on the basis of meeting functional requirements, it is easy to operate, maintain, and manage.
The entire system can work continuously 24 hours a day and 365 days a year as required, so the entire large screen display system must have high reliability, high stability, and other characteristics to ensure the continuous and normal operation of the system throughout the year. Due to the use of advanced LCD display technology, the LCD splicing large screen operates continuously for 24 hours without any damage to the display unit, and has no impact on the display effect. From installation and debugging to years of use, it can maintain the same display effect, achieve the same clarity, resolution, and display accuracy.
5. System economy
A reasonable performance price ratio is an important consideration in system design. Therefore, the selected equipment should consider both good performance and economy. In addition to the overall system cost, the long-term operating cost of the system should also be taken into account.
According to industry experience, the annual cost of replacing only the light bulbs for DLP projection TV walls (taking ten screens as an example) is as high as 70000 to 80000 RMB. So, choosing our company's LCD splicing large screen not only has the advantages of LCD, but also has a complete quality assurance system, stable quality, and excellent service. It is a wise choice for well-known products.
In summary, the overall design principle is that the system design should adopt a technologically advanced, mature and reliable, manageable and usable, high-performance, flexible and scalable, standard and open system, and be able to comprehensively consider the medium and long-term development plan of the system. It should adapt to the future development of multimedia applications in various aspects such as system structure, system applications, system management, and system performance, and maximize the protection of users' investments.
system composition 
The large screen display system provided in this plan mainly consists of the following parts:
1. LCD display module
PD46N3 46 inch industrial high-definition LCD display splicing wall unit quantity: 9 PCS; Arrangement: 3 rows and 3 columns
2. Installation method: Wall mounted bracket installation
3. Is it necessary to control the software
2. System functions:
The entire LCD large screen display system consists of a 46 inch industrial high-definition LCD display splicing wall matrix and other components. This large screen display system can display various types of signals such as Vedio, VGA, RGB, HV, DVI, etc. It can support standard definition, high-definition signals such as 720P, 1080I, 1080P, etc.
