What do you need to pay attention to when LED full color display?

Generally, pay attention to moisture-proof, dust-proof, anti-static, and do not press.

The main maintenance method (Ruishi): The whole picture is not a sporadic point of light, also known as a black spot, a bad spot, or a dead spot. (If a field doesn't appear, as long as the failure rate is within the range, it generally doesn't affect the display), and the whole screen will be dazzling.

The LED indoor full-color screen has a power jump box, and the operation is repeated as well. The LED display shows a line of abnormal results, flashing and flashing variegated colors. The led display does not show large, all black.

When the LED display is **** or **, the computer system software can show that the economy in different areas is normal, but the screen sometimes appears stuck and black. On the display screen, a board of LEDs flashes square, variegated, and several lights side by side show abnormalities. That's the board problem, you can replace the board that is abnormally displayed, and the indoor screen wall installation is generally magnet sucked, and the board can be replaced with a little force).

The large LED screen has an area display board that shows anomalies such as all the random colors in the flash. The computer and the Internet cable Maipu Glory LED large screen network cable are connected correctly, and the software will prompt "The large screen system was not found", even though the LED screen can be normal, but the software is all set to send data failure, brightness sending. LED display** The software window shows that the enterprise is normal, but the screen is disordered, staggered or divided into multiple windows to study and display the same picture separately.

Hello, your problem, I seem to have encountered it before, the following is my original solution ideas and methods, I hope to help you, if there is a mistake, I hope to forgive me! VOURY's micro-pitch LED display supports front maintenance or rear maintenance, if you are interested, you can learn about it. Thank you very much for your patience** and have a great day if it helps! Thank you!

One. Forward projection.

Forward projection is the front projection, the advantage of this display device is that the installation is simple, the picture is complete, but the disadvantage is the low resolution, two. DLP rear projection splicing.

DLP splicing wall is spliced by a plurality of display units, its main feature is the large size of the screen, and the seam is small, the mainstream size is 50 inches, 60 inches, 67 inches, with the increase of user demand for large screen size, 80 inches, 84 inches, 100 inches, 120 inches are also gradually used.

However, due to the characteristics of DLP rear projection splicing, there are obvious shortcomings, the larger the screen, the color and brightness will be uneven, and the internal luminous bulb will work continuously for 6000-8000 hours, and the brightness will be reduced. In order to maintain a good display effect, the bulb needs to be replaced at the end of the application, so the maintenance cost is very large. In addition, due to the large thickness of the DLP splicing unit, it is also necessary to leave enough space on the back of the screen body, which is a problem for some installation places with small space.

Three. LCD splicing.

LCD LCD splicing is following DLP splicing, PDP splicing, in recent years after the rise of a new splicing technology, LCD LCD splicing wall has low power consumption, light weight, long life (generally can work normally 50,000 hours), no radiation, uniform picture brightness and other advantages, but its biggest disadvantage is that it can not be seamlessly spliced, which is a big flaw for industry users with detailed and coherent display screens.

Since a single LCD screen will have a frame when it leaves the factory, the border (seam) will appear when the LCD is spliced, such as the frame of a single 21-inch LCD screen is generally 6-10mm, and the seam of the two LCD screens is 12-20mm. In order to reduce the splicing gap, there are several practices in the industry, one is narrow slit splicing, the other is micro slit splicing, micro stitching is that the manufacturer will buy back the LCD screen shell removed, the glass and glass splicing, this practice is more risky, if the single LCD screen is not well disassembled, it will damage the quality of the entire LCD screen.

Four. LED display.

With the continuous reduction of the spacing of the LED large screen and the continuous improvement of the resolution, in some areas with high use requirements, it has been completely able to replace the traditional large-screen display wall, and at the same time, the LED large-screen image is complete without a seam (strictly speaking, the seam is almost invisible to the naked eye), the size is not limited, the brightness of each part is highly consistent, the image level is rich, the color is uniform, whether it is a split-screen display or a combination of a large-screen display is extremely perfect, and the display effect is significantly higher than the traditional display mode.

There are three points to pay attention to when choosing LED display manufacturers.

1. Quality assurance (the quality must be passed in large quantities, and it will be very troublesome if there is a problem, mainly to delay the time of the enterprise).

2. Cost-effective (there are many LED display brands, and the production process is "similar" to shop around and choose a reliable company).

3. After-sales (electronic products, the most important thing is after-sales, no matter how loud the brand is, his after-sales service must be first-class).

At present, there are many ** LED displays on the market, and they are sold by pretending to be manufacturers, this market is very chaotic, and it is difficult to unify, and it is mixed; Service: **There is no service, you should pay attention to this, generally able to provide services, and can be regularly inspected, there is a home called Lofitte in Nanjing is a more powerful manufacturer, cost-effective or something is very good.

It is recommended that you ask a few more **, if the price difference is too large, the lowest has to be given up, because ** is too low, there must be a problem with the quality, much higher than the peers, it may be fooling, so you have to shop around, ask about after-sales, ask about quality, ask about payment... If you can, it is recommended to go to the company to see it in person... That's more reassuring.

Full-color LED display is a light source conductor with light-emitting diode as a light-emitting material, which is a solid-state semiconductor device that can directly convert electrical energy into light energy; And the full-color LED display is also an advanced digital information product, "it" will be computer technology, image processing technology, network communication technology, embedded control and other technologies successfully integrated in one, so that it has a flexible display area and can be spliced arbitrarily, high resolution, high brightness, low heat, long life, low power consumption and economical, environmental protection and durability and other performance advantages, but also a terminal display product that can display in all directions.

It is recommended that you ask a few more **, shop around, ask about after-sales, ask about quality, ask about payment... If you can, it is recommended to go to the company to see it in person... That's more reassuring.

For commercial customers, effective maintenance can ensure the stable operation of outdoor LED screens for a long time, and thus avoid interference with daily use due to equipment failure. Here are a few details that should be paid attention to in the use of Kinfor:

1.Switch sequence:

A: Turn on the control computer first to make it run normally, and then turn on the outdoor LED display;

B: Turn off the outdoor LED display first, and then turn off the computer;

2.If it is found that it is broken or other damage, it should be replaced in time, especially screws, pins, load-bearing beams, etc.;

3.Regularly inspect whether the anti-corrosion and anti-rust paint on the surface of the product and steel structure welding points is peeling off, and if there is peeling or rusting, the anti-rust paint or anti-rust paste should be sprayed in time;

4.The power supply should be stable, and the grounding protection should be good, do not use it in harsh natural conditions, especially in strong lightning weather, and regularly check the reliability of the lightning rod and grounding system;

5.During the rainy season, it is necessary to inspect to determine whether there is a water leakage;

6.Regularly check the power supply and signal lines for broken skin or biting;

7.Inspect the product power distribution system every six months;

First, when using the LED display, you should turn on the computer first, and then turn on the display. Because we know that the LED display is actually composed of two parts, one is the computer, and the other is the display. But we should do it in this order when we open it.

Just like when we use our own LCD computer at home, we should turn on the host of our computer before turning on the computer's display. Actually, it's the same thing. Because when the computer is turned on, the current generated is relatively large, which may be the current that the LED display cannot accept, and if it goes on for a long time, the LED display will be damaged.

When turning off the LED display, it is the opposite, turn off the display first, and then turn off the computer. The reasons for these two are the same, both are to avoid that when the computer is turned on and off, the LED display will be burned out, even if it is not burned, it will also have a certain loss of the display screen because the current is too large.

Second, you must pay attention to heat dissipation when using LED displays. Electrical appliances will produce the same kinetic energy and a certain amount of heat energy when they are used. Many times, this heat is generated by the use of electrical appliances at work.

But most of these heats are related to a heat dissipation problem. If heat dissipation is easy to solve, electrical appliances will not be easily burned out. We know that there is electricity inside the electrical appliances, and many of the electrical appliances are basically burned out.

We haven't seen a store with an outside display open in a hot summer. Because it is difficult to carry out the heat dissipation work at this time, the heat dissipation is very unsuccessful. In order to protect the LED display from being burned, the display can only be turned on.

And, we should pay attention to the fact that the LED display is not in the case of poor heat dissipation, it is best not to work for too long, if the lamp is burned out, it is very likely that a fire will occur.

LED display, like most electrical appliances, has all the characteristics of electrical appliances, and we are the same when we use them. Don't forget the problem of lightning protection with electrical appliances, and don't ignore the problem of heat dissipation, when using it, we can't always turn on the machine and shut it down immediately, and always start to restart after shutting down, so that the loss of the LED display is very large, and the interval between the front and back is at least a few minutes.
