How to solve the fault of LED display screen? There are many reasons why the full-color LED display screen can not display normally. Here is a summary of how to solve this problem. If the new screen is powered on, it may be that the control card is not set correctly or there is no cable (check the cable from the control card to the first chip), and this problem will also occur if the 5V power supply is connected incorrectly. If this phenomenon is suddenly found after a period of time, in addition to the failure of the control card, the biggest possibility is that the board water burns the chip or power supply. You can also try to connect a DVI interface display to see if the DVI output signal of the graphics card is normal. The DVI interface resolution of the ordinary card is 1024 * 768. The cause of LED display screen may also be the problem of graphics card or driver. Try to unplug the network cable on the rear terminal block of the display, press the debugging button on the…

Due to the improvement of monitoring technology level and data collection ability, it is very important that whether the LED display terminal can accurately display the collected data on the display wall at this stage, which directly affects the rationality of decision-making of higher departments. To meet the needs of the market, technicians of display terminals have improved the existing technology to make it seamless and high-definition, and soon a seamless jointed HD LED display was born. Seamless stitching is a special application that requires high projection display. It can fuse multi-screen images together and reduce seamless stitching to minimum of full coincidence. Seamless stitching technology requires not only a very large full-screen ，but also special requirements for the projection of very large screen. The biggest difference between BSV LCD…

The popularity of full-color LED displays on indoor and outdoor displays has led to the quality problems and design defects of various color screen products, resulting in a lot of fire accidents, which poses a great threat to the safety of employees. In this regard, we are just beginning to explain safety accidents in more depth. How do prevent fire accidents in practice? Full color LED display has the danger of fire, and the key lies in the defects of several main raw materials. First, wires. When most screens are used, the more information displayed per unit area, the greater the power consumption, and the higher the power stability standard of the conductor. In many wire products, only the wire conforming to national standards can ensure safety and stability. The second is electricity. At the same time, UL-certified power supply products are also the best choice for selecting products to ensure the safe and stable operation of power load with a reasonable conversion rate, and everything is ready under the condition of high temperature in the external environment. Third, protective materials. The aluminum-plastic plate of traditional outdoor display products ages rapidly due to high…

For traditional indoor and outdoor displays, stage displays will be different due to different uses and functions, and the requirements for configuration will be different. The following is a comparison between the LED screen for stage rent and the traditional display screen: Different selection models Due to the high display of stage rental screens on stage beauty, the screen playback effect requires clearer. Therefore, the general indoor environment uses the high-definition screen of the P3 P4 model, and even more severe will use the small-pitch P2.5 P2, etc., and the outdoor P6 P5 model. As for the traditional indoor and outdoor displays, due to the long viewing distance or low display requirements, the indoor generally uses P6 P5 models, and the most used outdoors is P10, followed by P16. And indoors are surface stickers, outdoor usually use plug lights, but sometimes also use surface mount products, currently for the rental market, has launched a variety of types of box series of products, models cover all the mainstream models on the market, including P3 P4 P4.8 P6 and so on. Cabinet difference Generally, the traditional outdoor LED display is a waterproof box and the structure is relatively heavy. Indoors are also simple cabinets; For led screen stage design, at present, they are usually made of die-cast aluminum Cabinets, with light and thin structures, high stability, more convenient to install and disassemble at any time, suitable for holding concerts and stage performances. Different installation methods As mentioned earlier, the stage rental screen is easy to dismantle and install, such as a concert, which can be disassembled and transported to another stage venue. The traditional LED indoor and outdoor display walls are usually fixed installation methods, and after the installation position is fixed, it will not be easily moved. The above is the biggest difference between the traditional display screen and the stage rental screen, and other differences include price quotations, configurations, installation environments, and so on.

If the LED display is used outdoors, it will face many challenges. The LED display screen will be affected by high temperature, cold waves, strong wind, rain and other bad weather. If these aspects are not done well, the safe operation of the display will be impossible. Today, I want to tell you how to install LED display to avoid water leakage. Add sealant to the backplate In order to save trouble, many friends do not add backplane or sealant when installing outdoor LED screens. After a long time, the components will certainly be flooded, and the LED display will have problems over time. I'm afraid of water. Once water enters the line, it will cause the line to burn down. These problems that can be easily solved cannot be…

Outdoor led advertising display with good stability, low consumption, radiation range and other advantages, used in outdoor information dissemination, is the most appropriate product. Basically, the common LED display has advertising screen, text screen, graphic screen and so on, but also constitutes the city life, brightness and light first choice. So in the outdoor construction of this kind of high-quality led advertising, should pay attention to what details, I believe these contents are the most concerned about the topic, especially for some technical construction personnel, know how to build outdoor, maintain advertising screen will strongly promote business advertising, information dissemination. Specifically, outdoor billboard LED electronic display installed with field survey, equipment construction, installation, commissioning and use of four links. Here are four basic steps on how to properly install an outdoor led advertising display: First, on-site survey This refers to some outdoor led display installation, should be specific to the environment, topography, luminescent radiation range, brightness acceptance capacity and other parameters of the new unified test, in order to ensure the smooth installation of billboards, require lifting installation, must be for the commander of the unified lifting program implementation, to ensure that the normal and stable use of the equipment. Second, LED equipment construction For some outdoor led advertising display, to…

Those who are concerned about the display sector are familiar with LED displays, but what is the pixel pitch? What's the big deal about it? It's possible that not everyone will be able to provide an accurate response. The engineer's take on the situation is as follows: What is the definition of pixel pitch? The density of pixels (LED chips) on an LED display is described by pixel pitch (pixel pitch), which is related to the resolution. It's also known as the dot pitch, which refers to the distance between the center of a pixel and the center of subsequent pixels ( In millimeters). A narrower pixel pitch means less space between pixels because the pixel pitch reflects the amount of space between two pixels. itc High end A series LED Screen multiple pitch options Comprehensive pitch selection: Including BL0.9/1.2/1.4/1.5/1.6/1.8/2.5 it covers the mainstream pixel pitches on the market, meeting the display needs of various application scenes. 1 cabinet+1 card+1 power supply: Universal cabinet design, one type of cabinet can use modules with different pitches; users can combine them freely. Follow-up product upgrades just need to replace the module; the cabinet can be recycled. For a single cabinet, only one receiving card + one power supply is required, reducing potential failure points of the screen, lowering the overall cost and the cost of spare parts. Key Points : The density of pixels is referred to as pixel pitch. The smaller the pixel pitch, the higher the pixel density and resolution. Pixel pitch is significant because it influences viewing distance. The closer the viewing distance, the lower the pixel pitch. The pixel pitch value is also reflected in the screen's viewing distance.

Surface Mount (SMD) Welding single or multiple LED chips to a metal bracket with a plastic "cup-shaped" frame (the outer pins of the bracket are connected to the P and N grades of the LED chip respectively), filling the plastic outer frame with liquid epoxy resin or silicone glue, baking and molding at high temperature, then cutting and separating into a single surface-mount packaging device. COB packaging technology CoB packaging is a kind of bare chip with conductive or non-conductive adhesive glued to the interconnect substrate and then led bonding to achieve its electrical connection. The COB package uses integrated packaging technology, because a single LED device is eliminated, and the packaging is then patched. It can effectively solve the SMD package display because the point spacing is constantly shrinking, the process difficulty is…

We often hear that the grayscale of the LED display is what is the brightness and brightness, so how much do you know about the grayscale and brightness of the LED display? Let's take a look at the explanation given by itc professionals. Led display grayscale, also known as color scale or grayscale, refers to the brightness of the degree of brightness. For digital display technology, grayscale is the determinant of the number of colors displayed. In general, the higher the grayscale, the richer the color displayed on the display screen, the more delicate the picture, and the easier it is to express rich details. The gray level of the LED display mainly depends on the number of A/D conversion bits of the system. Of course, the system's video processing chip, memory and transmission system must provide the corresponding bit of support. At present, the domestic LED display mainly adopts an 8-bit processing system, that is, 256 (28) level grayscale. The simple understanding is that there are 256 brightness variations from black…

The use environment requirements for an LED display utilized in outdoor advertising are substantially greater than for typical displays. Due to the varied environment, outdoor LED displays are frequently affected by high temperatures, typhoons, rainstorms, lightning, and other poor weather. What precautions can we take to keep the display safe in bad weather?   First, high-temperature resistance Outdoor LED displays are generally larger, and as a result of the higher power consumption, the corresponding heat dissipation is also higher. When combined with the higher external temperature, if the heat dissipation problem is not addressed quickly, it is very likely to cause circuit board heating short circuit and other issues. Ensure that the display board is in good working order, and when building the housing, choose for a hollow design that promotes heat dissipation. When installing, ensure that the display has good air permeability and, if necessary, improve the heat dissipation equipment for the display, such as adding air conditioning or fans inside, to help the display cool. Second, typhoon prevention The location of an outdoor LED display is various, as is the installation method; there are wall types, mosaic types, column types, hanging types, and so on. Then, during typhoon season, tight criteria for the load-bearing steel frame structure of the outdoor LED display are put in place to prevent the screen body from sliding off. The engineering unit must be built and placed in strict accordance with anti typhoon level criteria, while also having a seismic ability to ensure that the outside LED display does not fall off, causing injuries. Third, prevent heavy rain In the south, there are many rainy days, thus the LED display must have a high level of waterproof protection to avoid being eroded by moisture. In an outside application, the outdoor LED display should have an IP65 rating, the module should be sealed, a waterproof box should be used, and the module and box should be connected with a waterproof ring.   Fourth, lightning protection Direct lightning protection: If the outdoor LED large screen is not within the direct lightning protection range of nearby high-rise buildings, a lightning rod should be set on…

The biggest function of an LED video processor is to convert an image signal from an external source into a signal acceptable to the LED screen. How does an LED video processor complete the perfect display of the LED screen? 1) Signal conversion and switching, video processing equipment can complete the format conversion between many signals. Another important function of the video processor is to manage a variety of signals when multiple signals are connected, having  the flexibility to switch between them quickly. 2) Screen zoom, the full-color display is point-to-point, which determines that the full-color LED screen can only display the same size as its own physical resolution of the picture. The LED video processor can scale the image, output the picture at any size, and map the entire desktop to the LED screen. 3) Image quality is improved because the pixel…
