4X4 video walls are mainly used in information display terminals for transportation industries such as airports, ports, docks, subways, highways, financial and securities information display terminals, display terminals for business, media advertising, product display, etc., education training/multimedia video conference systems, and dispatching , Control room, radio and television, large-scale studio/performance venues, emergency command systems for military, government, and cities, mining and energy security monitoring systems, fire control, meteorology, maritime, flood control, traffic hub command systems, etc.
The 4X4 video wall controller can realize image split display, single screen split display, single screen separate display, any combination display, LCD image splicing, full-screen splicing, vertical screen display, the image frame can be compensated or covered, and it supports digital signal roaming, Scaling and stretching, multi-screen display, setting and operation of various display plans, real-time processing of full HD signals, and more powerful functions than general decoders.
The following iSEMC introduces the 4X4 video wall solution in the Philippine pharmaceutical industry:
1. Confidentiality reason, use a pseudonym of Philippine Lenovo Pharmaceuticals (Confidentiality reason, use a pseudonym), due to the lack of systematic monitoring, results in the surveillance video in the production area being distributed in each production workshop. If you need to watch the scene, go to each workshop to watch it intelligently. , Once there are potential safety hazards at the production site, preventive work cannot be done in a timely and effective manner.
2. The production control method based on Philippine Lenovo Pharmaceuticals (pseudonym) is also the same as video surveillance. Each unit and control method adopts independent control and viewing in the workshop, which consumes manpower and cannot concentrate and effectively process the workshop and workshop. Control system between DCS and SIS.
Based on the above reasons, when Party A has ideas for renovation of the workshop and the entire plant area, the iSEMC system cuts in, moves from independent operation to centralized management of the system in each workshop, and integrates all control systems, detection systems, and temperature sensors. The system, network system and surveillance video system are all gathered in the control center, and the physical connections between all systems are connected one by one, gathered in the control cabinet of the computer room, and projected on a 55-inch 4x4 screen through a 4X4 video wall controller. Achieved the purpose of centralizing all systems to the management of the video wall control system.
Philippine Lenovo Pharmaceutical (pseudonym) 4X4 video wall controller solution is composed of image display system, image processing system, signal source switching system and other subsystems.
The video wall adopts advanced and high-speed image processing technology to realize the unified processing of multiple signals, with high-definition, high-brightness and high-color gamut LCD technology, embedded hardware splicing technology, multi-screen image processing technology, and signal switching technology Together, they form an LCD Video Wall display system with high brightness, high definition, low power consumption and long life.
System feasibility
LCD splicing wall splicing can be combined arbitrarily (M×N). According to the system scale, size and application requirements of different customers for the splicing system, iSEMC will select appropriate products and splicing methods, and propose specific implementation plans to meet the application requirements of the system.
Through the RS-232 communication interface/other interfaces to control the image controller to achieve any combination of display mode switching, signal switching, etc. Different needs of customers, to create a personalized system, provide different implementation plans and technical support.
Practicality of the system
According to the user's requirements for input signals, different video processing systems can be selected to realize the input of VGA, composite video, S-VIDEO, YPBPR/YCBCR, DVI/HDMI signals, and IP network signals to meet different use occasions and different signal input need. Through the control software, various signals can be switched, spliced into full-screen display, display in any combination, image stretched display, image roaming display, image superimposed display, etc.
System reliability
The splicing unit used in the iSEMC LCD splicing wall adopts an industrial-grade LCD special screen. The splicing unit can work continuously 24 hours a day and 365 days a year. The splicing unit has the characteristics of reliability and high stability to ensure the stable and reliable operation of the system. Due to the characteristics of low power consumption, light weight, long life, and no radiation, the LCD splicing wall has extremely high reliability.
System economy
Considering the economy of the system, it should be considered from the perspective of cost performance. The economy of the system is meaningful only under the premise of high performance and high quality.
Under the premise of the economic market, all enterprises and agencies are leading the reduction of expenditures, but the demand for liquid crystal display products is still increasing. Therefore, while meeting the basic needs of customers, more cost-effective products will be favored by customers.
Openness and scalability of the system
Digital network ultra-narrow-edge intelligent LCD splicing system follows the principle of open system. In addition to direct access to VGA, RGB, and video signals, the system should also be able to access network signals, broadband voice, etc., and can switch various signals at any time And dynamic comprehensive display, to provide users with an interactive platform, and support secondary development; the system should have the ability to add new equipment and new functions, making hardware expansion very simple. At the same time, the software only needs to be expanded and upgraded to meet the requirements without modifying the source program. The hardware and software parts of the system can easily "advance with the times".
The LCD splicing screen system consists of a 4X4 55-inch ultra-narrow LCD splicing wall.
The overall scale of the system is as follows:
① LCD splicing unit (16 sets)
② Front maintenance bracket (16 units)
④ PC (1 built-in two 8-screen cards)
⑤ Control software
⑥ Various wires
