What is the controller for the LCD video wall to enter and exit? Did you choose the right one?

When corresponding to a real-time screen display system, under normal circumstances, customers will ask how many signal processors are needed, which is actually controlled by the control that forms the screen.
Outside the screen, the most important display is the complete signal processing equipment, which also determines the function of the entire screen. At this time, we need to configure the signal processing equipment according to our needs.

Distributor: It is commonly used when there is only one signal and input to display a large screen.
According to the number of image screens, the corresponding distributors are 1 in 4 out, 1 in 8 out, 1 in 16 out, etc.

Matrix: came into being on the basis of the simultaneous distributor. The function of the matrix is ​​more single, it supports a variety of signal source input, and can be displayed on a large screen.
For example, we have 3 computer signals that need to be displayed on the screen, the upper limit is 15 screens, and a 4-input 16 matrix can be configured to switch and display each signal at the same time.

The decoder is professionally used for the decoding of video surveillance signals on the screen, including the front end connected to the video screen machine.
In addition to the function of the matrix, it can also achieve the screen split display function, such as displaying up to 64 images in one screen. This greatly improves the arrangement of the screen pictures.

Image and video processor: In some large control room, in addition to simple and decoding functions, sometimes they can also enlarge the screen and screen functions,
such as enlarging a certain image on the screen and displaying another image on it, compared to decoders The function is smaller.

The panels of industrial-grade LCD video wall have undergone industrial-grade treatment, special treatment in order to meet the requirements of the industrial field.
For example, it needs to be turned on continuously for 24 hours, which is equivalent to the need for uninterrupted work, and the performance requirements for the panel are extremely high.
For example, in some monitoring rooms, in order to achieve safe management and control, it is very normal to start the display all the year round.

And our common LCD screens are conventional LCD panels, such as TV screens, monitor screens, and mobile phone screens.
Because it does not need to be turned on and displayed all the time, it does not need to be made into an industrial grade.

The difference between the panels directly affects the continuous display in the later stage.
Industrial-grade panels support 365 days of continuous uninterrupted machine operation, while conventional panels do not.

The comprehensive lifespan of industrial-grade LCD video wall can reach more than 100,000 hours, which is equivalent to about 10 years of continuous startup, while the ordinary LCD screen is about 30,000 hours, which is very relevant.

This is due to the structure of the panel and the reason why industrial-grade panels are slightly more expensive than ordinary panels.

Ordinary screens are mostly used in commercial display and civilian fields, such as computer monitors, TVs, mobile phone screens, smart watches and other electronic devices, and most of them are small screen displays.

The industrial LCD video wall is mostly used in large-screen display occasions and control rooms, which usually require multi-screen splicing.
At the same time, it also needs to be turned on continuously for a long time, such as security monitoring display system, command and dispatch large-screen system, conference display, exhibition display platform, big data analysis platform and other occasions.
Like some occasions that focus on display and monitoring, usually multiple LCD splicing screens are spliced ​​into a large screen to display hundreds of video monitoring screens, which need to be continuously powered on.

The 2021 Singapore New Energy Electric Vehicle Show (MOVE Asia 2021) will be held on September 8-9, 2021 at the Suntec Convention and Exhibition Center in Singapore.

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)

③ 4x4 video wall controller

④ PC (1 built-in two 8-screen cards)

⑤ Control software

⑥ Various wires

How do the four monitor splicing screens form a big screen?

Are you sure what you see in the mall are LCD monitors?

In fact, it has already existed, it is to imitate the LCD splicing screen, using an external splicing processor to achieve this effect.

Nowadays, many commercial advertisements are played on large screens. Supermarket stores will install a splicing large screen composed of multiple LCD monitors or TV sets to play video advertisements. Then iSEMC uses 4 as an example to solve 4 LCD TVs or monitors. How to form a big screen

In fact, there are two large-screen solutions composed of 4 LCD monitors:

The first is to buy a good LCD computer, configure a relatively high-end multi-screen graphics card, through the multi-screen display 4 high-definition interfaces to output to the back of 4 LCD TVs or monitors, and then set up a multi-screen card, so as to achieve a large splicing Screen picture. If you do this, the effect is not very good, and there is a risk of computer virus infection. It is not recommended for customers.

The second is that you need a 4 TV Video Wall Controller, or a splicing box. Now there are many brands of such products. Just buy one. The iSEMC 4TV Video Wall Controller can quickly switch splicing/single display status, and supports multi-interface input. Yes, it is convenient for multi-signal use, and can also be used as a signal switcher. Compared with the previous solution, the second one is more versatile, whether you need a 4 TV/6 TV video wall controller, you can use it.

4 Features of TV Video Wall Controller:

1. The test signal of the wall can be generated for the adjustment of the unit. The unit has a picture-in-picture display function, and a single screen can display two picture-in-pictures, which can realize intelligent adjustment of brightness.

2. The system is easy to expand. The large-screen splicing multi-screen controller supports up to 256 RGB outputs and can drive 256 units.

3. Application systems such as the control center can be clearly displayed on the LCD splicing screen without affecting the normal use of the user system. The software splicing system can ensure the superimposition of the resolution, so that the graphics that cannot be displayed on the small screen are clearly displayed on the whole screen.

4. Full hardware architecture, no risk of virus infection, and good security.

5. The start-up time is extremely fast, less than 5 seconds.

Sixth, the output of the graphics card is an RGB signal, and up to 48 outputs can be configured. Support multi-channel video input, up to 128 channels, compatible with signal sources.

Seven, the video window can be zoomed arbitrarily, full-screen roaming, support PAL/NTSC/SECAM, automatically identify and track changes in the system.

8. The operation interface is intuitive and easy to use. The call and control of graphic signals has nothing to do with the user's application program, ensuring the safety of the user system.

9. The system has a secondary development function, which can be developed on the basis of the controller and the original software code according to the specific requirements of the user.

10. The splicing system is reliable and safe, and has the ability to work 7×24 hours. Ensure the stability of the system. It can be equipped with dual power supplies, fans, and can be hot-replaced.

11. The output display format is XGA or SXGA, which directly drives the LCD splicing unit.

12. Divide a channel of video VGA signal into M×N combination effects.

13. The picture and function of each large-screen display should be arbitrarily defined, and the large-screen display has a short response time to call up the picture.

14. Automatic adjustment of brightness, contrast, chroma and smoothness of image parameters.

15. Support remote multi-user operation: users can operate the large screen with a single mouse or multiple mice and keyboards through the local area network to realize the splicing of the large screen. Multiple operators can use the mouse and keyboard of their respective desktops to interactively operate the large screen on the large screen. Open or close the video and RGB windows, change the position and size of the windows, etc.

16. The user can open multiple active windows at any position on the screen. All windows should be able to move arbitrarily, zoom in or zoom out, and ensure that the details of the screen are not lost when the screen is zoomed, zoomed, or moved, such as characters without missing strokes, etc.

4 TV video wall controller system solution (2x2 video wall), usually composed of 4 LCD monitors of the same specification, video wall control software, power supply and cables connected to the display.

If you have 4 TVs of the same specification, you can use the TV as your splicing screen, and match it with a suitable 4TV video wall controller, you can get it;

First of all, LCD video walls and LED video walls are two completely different concepts.
LCD is a liquid crystal screen, used for display;

LED refers to Light Emitting Diode, and the LED we are talking about refers to a liquid crystal display that uses light-emitting diodes as a light source. The liquid crystal itself does not emit light and needs another light source to shine. Now you can use LED as a backlight source, so there is LED video wall.

OLED is the same as LCD. OLED is an organic light-emitting diode, which can be used for display. OLED does not need a backlight. It emits light and displays color by itself, which can replace LCD. At present, OLED is mostly used for mobile phone screen display ( Such as ultra-thin mobile phones).

(LCD video wall on the left, LED video wall on the right)

1. Application
Different LEDs are basically used for advertising. They are mainly used for playing videos, pictures, and text. LEDs are used for press conferences, evening parties, shopping mall advertising screens, and store text bar screens.
The LCD splicing screen is mainly used for surveillance video display, meeting rooms, exhibitions and other occasions, which is due to its split screen, support for multi-signal input, and achieve high-definition resolution display, close-up clarity is higher.

2. Installation environment
Since the liquid crystal itself is not waterproof, it is mainly used indoors; while LEDs can be used in various occasions, both indoors and outdoors;

3. Patchwork
LCD splicing screens have splicing gaps of different sizes, ranging from 3.5 to 0.88mm on both sides, so there will be physical black borders between the screen and the screen after splicing, which will affect the viewing effect when the whole screen displays a picture; and LED There will be no such worries, no matter how spliced, the LED display has no black borders;

4. Different display effects
Different LED dot pitches result in different resolutions and different display effects. At present, the dot pitch ranges from 10mm to 1mm. The smaller the dot pitch, the clearer the display. The resolution of a single LCD splicing screen is 1920*1080, and the resolution can be superimposed after the screen is spliced. Therefore, the LCD splicing screen has a higher resolution, which is more suitable for playing high-definition film sources, and is clearer when viewed close up. , There is no mosaic phenomenon.

5. Different after-sales rates
The LCD splicing screen technology is very stable, the average life span can reach more than 60,000 hours, and it can be turned on and displayed for 24 hours continuously. As long as the panel is not impacted by external forces, there will be few after-sales problems. The LED is not the case. It has a certain dead light rate. Some lamp beads on the module will turn black or red. As time goes by, the probability of this dead light will become higher and higher, which will seriously affect Display effect, if you want to repair it can only be removed and re-welded or replaced, the after-sale rate is higher
.
6. Power consumption
The splicing screen of the same size and area has much lower power consumption than the LED screen. The splicing screen supports power-off and power-off at will, but the LED does not. Summary: So we choose to use LED or LCD splicing screen basically can be analyzed from the above several, if it is used indoors, display monitoring or multiple computer content can be spliced ​​with LCD, if it is used outdoors, or indoor remote viewing Use LEDs. The eyes will have a very obvious burning sensation when watching LED for a long time. It is recommended to use LCD splicing screen in the meeting room. The color/contrast/long-time viewing effect is much better than that of LED.

Whether it is an LED video wall or an LCD video wall, you should choose it according to the actual usage. In iSEMC, you can get a quotation for two video walls;
