[LED large screen] LED large screen play is generally divided into synchronous control and asynchronous control. Asynchronous control is commonly used in single and double color LED display screen

The system is applied in the field of LED full-color display.

synchronous display system is based on the computer synchronization mode. The display screen is connected with the computer by network cable. The synchronization system is composed of sending card and receiving card, and the system is composed of sending card and receiving card

When the area of the external display screen is less than 80 متر مربع, it usually adopts one sending card and 40-50 receiving cards (two boxes and one card). The indoor LED color screen is relatively systematic

This is slightly higher because its pixel density is much higher than that of the outdoor electronic screen.

Part 3: LED display accessories

for electronic display screen to work normally, it is not enough to have led display screen. Also need some accessories to use, the most basic accessories are: computer(desktop computer), air conditioner (heat dissipation is very important), lightning arrester, power distribution cabinet, audio amplifier (خياري), TV card (خياري), multi-function card (خياري)

Automatic adjustment of display screen temperature, سطوع, humidity and other physical data), معالج الفيديو (خياري), إلخ.

the cost of accessories varies greatly according to different brands. It is normal for one of them to have a difference of several thousand yuan, and the display screen manufacturers only purchase on behalf of others

Purchase, do not produce related accessories, so most of the accessories are recommended for customers to purchase locally.

Part IV: LED large screen steel structure, foundation frame.

the general installation methods of LED screen are: wall mounted, floor mounted, inlaid, column mounted and roof mounted. What we see now is the LED screen,

Both the large screen attached to the wall of high-rise buildings and the LED electronic screen of indoor background wall are fixed by steel structure.

The cost of the foundation frame is second only to that of the LED display screen. The price of the ordinary outdoor steel structure is between 1200-1500 يوان / m2

The cost of wall mounted LED panel square pass structure is about 600 يوان / m2, and the cost of Optimus pillar fixed steel structure and column foundation reaches 2000-2500 يوان / m2. by

It is suggested that the manufacturer should provide the construction drawings and the customer can make the welded steel structure locally.

Part V: logistics, مواصلات, تثبيت, إلخ

نعم. In order to protect the safety of the goods, all the goods are made of pearl cotton, plastic film, carton, wooden frame, and the most reliable logistics company in China.

As the most important part of the development of new type advertisement, LED display screen should be understood and paid attention to in detail,

Control system is one of the most important parts, so how can we distinguish these things? اليوم, I will give you a detailed introduction. The control system of LED display screen control system is also a very important part; ال control system of LED display screen generally includes synchronous system and asynchronous system.

synchronization system: the LED display is equivalent to a large display, and the contents on the LED display screen and computer display are completely synchronized

The operation is displayed on the LED display screen; if the computer is turned off, the LED display screen will also be closed and no longer display the content; it is suitable for the high real-time requirements occasions, such as video screens, إلخ.

DVI display card + 256 gray level control card, control points 1280 × 512, control

The range is Φ 5 – 9.76 m long, 3.9 m high, and Φ 3.75 – 6.1 m long and 2.448 m high.

asynchronous system: the LED display screen and the computer display content are not synchronized; the content to be displayed is sent to the control card after being edited on the computer,

After the control card is powered on, the contents stored on the card can be displayed, even if the computer has been turned off;

It is suitable for occasions with low real-time requirements, such as single and two-color banner screen, playing some notice slogans, إلخ.;

realizes the function of offline and storing information, while PC only plays the function of modifying the content of LED display screen, and the display function is realized by asynchronous control

The advantage is that a PC can control multiple LED displays, so it can realize multi screen networking. The above is a detailed introduction to the control system.

LED display screen is divided into indoor display screen and outdoor display screen. لكن, no matter what kind of display screen, you need to pay special attention when installing.

This is a kind of circuit LCD display system that can’t be collided, so we should pay special attention to the installation of indoor P4 high-definition full-color LED display screen?

1, pay attention to the lightning protection of buildings and screen body: to prevent the display screen from strong electromagnetic attack caused by lightning, the screen body and external packaging protection of the display screen

The layer must be grounded, and the resistance of the grounded line should be less than 3 Ω, so that the current caused by lightning can be discharged from the ground in time.

2. Waterproof, dust-proof and moisture-proof problems of the whole screen: seamless connection should be made at the connection between the box and the box, and the joint between the screen body and the stressed installation object

Avoid water leakage and damp. There should be good drainage and ventilation measures in the interior of the screen. If there is water accumulation inside, it can be treated in time.

في نفس الوقت, it is necessary to select the industrial chip with the working temperature of – 40 درجه مئوية, أي. 80 درجه مئوية, to avoid the failure of the display screen to start due to too low temperature.

4. Do a good job of ventilation inside the screen: when the screen is powered on, it will generate certain heat, if the heat can not be discharged, it will accumulate to a certain extent

The internal environment temperature will be too high, which will affect the work of the integrated circuit. In serious cases, it can lead to burnout, so the display screen can not work.

لذلك, it is necessary to do a good job of ventilation and heat dissipation measures inside the screen body, and the temperature of the internal environment should be kept between minus 10 ℃ and 40 درجه مئوية.

the above four points are to help you summarize some matters needing attention during installation, but the specific situation should also be analyzed in detail, if you have any installation.

When the شاشة عرض LED is used, it is inevitable that there are abnormal conditions, such as unstable circuit, insufficient screen brightness, إلخ., sometimes it is difficult.

There will be no lighting of the unit board. Here are five ways to check the LED display cell is not bright solution.

1. The whole LED electronic screen is not on.

1. Check whether the power supply is connected to the signal line.

2. Check whether the test can identify the interface; if the test red light flickers, it is not identified. Check whether the light panel is the same as the test power supply ground, or whether the light board interface has signal

لا. 1 is short circuited to ground, resulting in unrecognized interface. (Intelligent Test)

3. Detect whether 74hc245 has false soldering short circuit and whether the corresponding enable (EN) signal input and output pins on 245 are faulty soldered or short circuited to other lines.

Find the pin controlling the column on the module and test whether it is connected with the output end of driver IC (74HC595 / TB62726,,,).

With the advent of the information age, LED video walls has become an indispensable part of life. It can be seen everywhere, square stations everywhere. Different LED displays can be seen everywhere at any time.

it is a system engineering integrating optics, structural mechanics, electronics and computer science. وفقا للإحصاءات, all LEDs in China

90% of the display screen has large or small faults. Based on our years of experience, we have summed up the main attribution of these faults, namely

With these, we can control the fault from the source and improve the quality of the display screen. ال 80% failure of

LED display screen is caused by the following factors: wiring harness, terminal, connector of AC power distribution, signal and low voltage

DC connection harness and connector, switching power module, fan, plastic shell assembly.

if these interfaces, cables, power supply and bottom shell are not properly selected, the LED display screen will be black or partially black, and the screen will be mosaic

ز, no signal, إلخ. These are also very difficult to maintain the problem, so we pay attention to it in the production process, reduce the failure rate. Another 80% of the other failures are caused by the following reasons: solder joints, capacitors, terminals on PCBA, LED lights, and the protection of the box

Leakage dust accumulation caused by insufficient protection level, corrosion of hardware and hardware of external leakage screw, and control board card.

Business card printing or software problems will lead to abnormal image display.

outdoor LED display must be designed in strict accordance with the testing standards, waterproof and dustproof, wind and high temperature resistance, otherwise it is easy to appear various kinds of LED display

Failure, even the entire شاشة عرض LED scrapped.

in addition, the display operator should master the relevant basic knowledge, have good use habits, and professional maintenance personnel

It can also reduce the failure rate to a certain extent.

as long as we pay attention to the above points when using, we can generally avoid similar situations and increase the service life of products.

First: choose high-quality LED display screen

LED display screen is composed of mask, circuit board and bottom shell. Waterproof glue used for fireproof and moisture-proof LED display screen is also led display screen’s Important components. لذلك, the selection of better quality display products, starting from high-quality raw materials.

the mask and bottom shell of LED display screen shall be made of PC glass fiber material with flame retardant function which has passed the quality verification. And the circuit board Black three proofing paint to prevent weathering, corrosion and other issues.

second: to solve the problem of heat dissipation

the larger the area of LED display, the greater the power consumption and the more obvious heating. فضلاً عن ذلك, the summer sun is violent and the external temperature is high, It is difficult to dissipate heat.

in order to solve the problem of heat dissipation, it is necessary to adjust the external design and internal structure of LED display screen, and adopt hollow design with high density

Precision design circuit board, hollow design, ventilation and light transmission, so that without sacrificing brightness and contrast, wind load can be reduced

Reduce fixed installation cost and improve product stability.

third: installation specification

LED display belongs to high-power electrical appliances and is prone to short circuit. But the real quality of LED display screen from wire to structure

Short circuit should be avoided. لكن, in the installation process, a little carelessness and negligence may cause unexpected danger.

To ensure safety, LED display manufacturers need to guide the whole process of installation to ensure that the positive and negative poles are connected and the circuit connection is firm.

 

With the rapid development of LED display screen, large screen system is becoming more and more popular, especially for large parties, concerts and so on.

The demand for large screens is gradually increasing. But in terms of structure, Large screen also has many kinds of classification, are you clear

اليوم, I’d like to introduce it to you.

The first type is the DLP large screen

DLP large screen wall splicing system. The principle is that the cold light source emitted by UHP bulb is passed through the condensing lens and the light is evenly distributed through rod

Homogenization: the processed light passes through a color wheel to divide the light into RGB tricolor (or more colors such as RGBW),

Then the color is projected onto the DMD chip by the lens, and finally the reflection is imaged on the projection screen through the projection lens.

The second one is the plasma large screen because of its ultra-thin body, large display area and excellent display performance in a variety of environments, the plasma display has become one of the most important types of plasma display.

في الوقت الحالي, the most advanced plasma large screen splicing display equipment. The core component of plasma display is plasma screen, which is combined with BSV liquid crystal.

The difference is that it has some pixels, each pixel unit is composed of red, green and blue pixels, and the inner surface of the outer screen is luminous.

The phosphor is similar to the phosphor in CRT picture tube, which can provide vivid and rich colors.

Very short response time and very wide viewing angle. Each pixel unit is controlled by a separate electrode, and the video signal is transformed.

After that, the electrodes respond, and each pixel can produce more than 16.7 million colors through the combination of three primary colors and different brightness Color.

The multi variable large screen function: single screen split display, single screen separate display, arbitrary combination display, full screen LCD splicing, double splicing LCD.

Mosaic screen, vertical screen display, image frame can be compensated or covered, support digital signal roaming, zooming and stretching, cross screen display.

The setting and operation of display plan, real-time processing of Full HD signal.

the fourth type, LED large screen.

LED screen is a new type of imaging electronic equipment made of light-emitting diodes in order. Because of its high brightness and visual angle

With the characteristics of wide range and long life, it is widely used in outdoor large screen and other products.

Five common installation methods for the led video walls.

1. Mosaic installation: suitable for small indoor screen. Due to the small installation space, in order to not occupy space, according to the screen surface.

The area of the same size is dug out on the wall, and the LED display screen is embedded in the wall.

2. Wall mounted installation: it is mostly suitable for the installation of indoor LED display, with a small area (less than 10 متر مربع), and the wall requirements are as follows

Solid wall, hollow brick or simple partition wall are not suitable for this installation method.

3. Hanging type installation: it is mostly used for LED electronic display screen of station, LED electronic display screen of airport and other large places to play the role of indicator signs. Small screen area is required. (less than 10 متر مربع) it is required to have a suitable installation site, such as a crossbeam or lintel above.

In general, a back cover should be added to the screen.

4. column type installation: it is mainly used for the installation of LED electronic display screen for outdoor advertisement, with wide vision

The surrounding area is relatively open, such as square, parking lot, إلخ. According to the size of the screen area can be divided into single column and double column type Installation.

5. Roof type installation: mainly suitable for outdoor advertising LED electronic display, the installation site is mainly on the roof of the building.

With the increase of building height, the wind protection level should be considered.

generally, the display screen we install is mainly used in outdoor and indoor venues, so the above five methods are enough to cope with Most places.

في الوقت الحاضر, LED display is irreplaceable! In all advertising media, outdoor advertising is the most old media. LED display screen also has the characteristics of high useful arrival rate, compared with the investment mode of TV, newspaper and other media, the quotation is lower. These common values make the media of full-color LED display screen become the new upstart of outdoor media.

such as the CBD center area of New York Times Square in the United States and the dense LED display manufacturers in Ginza, Tokyo, اليابان

It is not only the function of advertising and promotion, but also the symbol of the identity of the world-famous large companies – companies with a dominant position in the industry can

The companies that broadcast ads here, together with the companies that broadcast ads here, have made people feel the global position of its brand.

LED display screen is a new type of information display media developed rapidly in the world in the 1990s, which connects with modern high-tech,

It has a series of advantages, such as energy saving, environmental protection, bright colors, dynamic pictures and text, and wide visual scale.

outdoor LED screen advertising has large screen area, shocking visual effect, and can fully attract the audience’s attention. It is a brand new media and high-tech Contact. These changes cast the common and irreplaceable value of outdoor advertising media.
