How to Set the Parameters of LED Display Control Card?

When setting the software parameters of the led display control card, you often encounter some problems. For example, don't know how to set the parameters, what the password is, can’t find the software, etc. Different manufacturers of control cards have different parameter items. Meiyad has classified it into three categories: basic parameters, auxiliary parameters and core parameters. Outdoor led display control software has three parameters:Firstly, basic parameters If the the basic parameters settings are incorrect, communication or display will not be possible or the display will be abnormal. The basic parameters include 10 items including display width and height, control card address, baud rate, IP address, port number, MAC address, subnet mask, gateway, refresh frequency and shift clock frequency. Second, auxiliary parameters Auxiliary parameters are parameters set for better display and control, including control card name, communication display mark, brightness and screen switching time. Third, core parameters The core parameters are necessary parameters for the outdoor led display. If the settings are incorrect, the display may not be displayed at all, or the screen may be burned out. The core parameters include cascade direction, OE polarity, data polarity, display type, color, scanning method, point order and row order, a total of 8 items. LED display control software parameter configuration method: For the configuration of basic parameters and auxiliary parameters, input boxes and selection boxes are provided. After the user inputs and selects, they can connect to the display screen and set directly. As for the core parameters, it can be completed using three methods: professional quick check, intelligent configuration and external file configuration. 1. Professional quick check For common and commonly used models of led screens, the parameters are generally fixed. In this case, they can be organized into files or tables in advance, and the configuration can be loaded during debugging. 2. Intelligent configuration For uncommon or uncertain led displays whose parameters are unknown, intelligent configuration can be used to determine their configuration parameters and then be saved for later use. 3. External file configuration Import smart configuration or other external files built into the configuration. Among the three configuration methods of core parameters, intelligent configuration is a more important configuration method. Its main processes and functions are as follows: 1. Start smart configuration. 2. Through the wizard, the user and the led display can make human-computer interaction selections and start the intelligent configuration operation by filling in the initial parameters, determining the OE polarity/data polarity, determining the color, determining the scanning method, determining the point sequence, and determining the row. sequence and generate configuration parameters to complete the determination of core parameters. 3. Return to intelligent configuration parameters. 4. Connect the display and set parameters. 5. If correct, perform output parameter operation. 6. Select the external file and save it for later downloading. At this point, the intelligent configuration of the display screen is completed. Summary: The outdoor led display needs to be correctly configured with more than 20 parameters before it can be lit. You can imagine how cumbersome and complex it is. If the settings are incorrect, the display may not be displayed at all, or the display screen may be burned, causing significant economic losses and delays in construction. Therefore, it is understandable that some led display control software is complex in design and inconvenient to use for the sake of caution and stability.

Meiyad Tell You How To Install Outdoor LED Display

When you want to buy an outdoor LED display, it is very important to quickly understand the installation process and precautions, which can reduce 83% maintenance troubles for your LED display screen, thus prolonging the service life of the outdoor billboard display. Let's quickly understand: 1) Four Steps for the installation of led displays for outdoor billboardsThe first step: Fixing of outdoor LED display When determining the high-level installation position, building a complete “cuboid” solid steel structure and adding a bracket on the back of the display screen is necessary. In this installation step, the entire outdoor LED display can be firmly supported for a long time. Step 2: Install the cabinet of the outdoor LED display The LED display screen is a large screen made up of individual cabinets. As long as any LED box is connected to the power supply, it becomes a small LED display that can display content and text. In this step, you only need to install these “small rectangular blocks” in the calculated steel structure space. Step 3: Power on and debug the outdoor LED display After the LED cabinet of the outdoor LED display is installed, it needs to be connected to the power supply, and then debug and test whether each screen is lit up, whether the screen display is clear and the color is correct, etc. In this step, in addition to debugging, you also need to check whether the lamp beads are damaged in different monochromatic displays. Step 4: Decoration of Outdoor LED Display The decoration of outdoor LED display screens is generally determined according to the building and the surrounding environment. For example, the decoration in the outdoor children’s playground will be more cute and exciting. If it is in the shopping mall, the high-end fashion decoration will give extra points to the advertisement. In this step, it is still visually beautiful, making the LED display screen integrated with the external building, making it more attractive. 2) 5 Useful Outdoor LED Screen Installation Tips1. Installation of lightning protection devices on display screens and buildings Do you know why you need to install lightning protection devices? The LED display is easily “attacked” by ultra-high voltage electricity, which instantly burns out the internal electronic equipment. Yes, if there is no lightning protection device, when there is a thunderstorm, most of the lightning power is 1-1 billion joules. In other words, just ordinary lightning is about 280 kWh, far beyond various countries’ voltage. Standard, even the highest voltage standard in the UK in Europe is only 240V, while the voltage standard in other countries is between 120 and 220V, which is very easy to burn out the internal structure of the LED display. Therefore, to protect the electronic components inside the LED, it is necessary to install a lightning arrester. 2. LED display installation waterproof device LED displays installed outdoors are greatly affected by the environment, so they must have solid environmental resistance. The most taboo thing for electronic equipment is to get wet with water. Water is fluid and very conductive, and it is easy to burn out the circuit when disturbed by water. In addition, the damage caused by water to electronic products is easy to rust. Once the electronic products are rusted, the circuit will lose its electrical conductivity. Therefore, after the first storm, please check whether the screen is leaking. If there is, please use a hair dryer to dry it. It is important to keep the LED display dry and prevent water from flowing into the electronic equipment in the box. (If there is a water leakage problem, for the sake of safety, you must find a professional to find out the cause) 3. Selection of circuit chips The circuit chip chooses to resist the temperature of the external environment. If the extreme temperature climate is encountered, a good industrial-grade circuit chip can operate normally even if the operating temperature is between minus 40 degrees Celsius and 80 degrees Celsius. We often see the fire or crash of the LED display screen in a high-temperature environment or the start of the LED display screen in a low-temperature environment; this is because the circuit chip of good quality is not selected. Of course, there are other reasons, such as very few in the later stage, maintenance, prolonged use, etc. Therefore, it is very important to have a circuit chip that can adjust according to the outdoor ambient temperature. 4. Install cooling equipment Even if there is a good circuit chip, why does the outdoor LED display box need cooling equipment? The main reason is that the screen will generate a certain amount of heat when it is powered on and working. If the heat cannot be discharged and accumulated to a certain extent, the internal temperature will become higher and higher, which can cause serious burns and make the display screen unable to run the job. Therefore, do a good job of internal ventilation and heat dissipation measures of the LED screen to keep the internal temperature between 10 degrees and 40 degrees, which is beneficial to the life of the outdoor LED display. Although there are many cooling systems in the outdoor LED display, due to the changeable and extreme environment, in countries with high temperatures and high heat, air conditioners are generally installed inside to cool down, which is safer and more stable. 5. Choose ultra luminous light emitting diodes The biggest reason for choosing ultra-high luminosity light-emitting lamp beads is the display effect, which will not affect the displayed advertising content because of the high-brightness sunlight outside. The internal photosensitive chip adjusts the brightness according to the environment. When the brightness of the outdoor LED display is not enough, in a hot and bright environment, the displayed content will have problems such as light color and blur. The choice of waterproofing, cooling system, and brightness need to be explained here. When purchasing, you need to explain these data to the merchant or manufacturer of the display screen. For example, IP65 is required for waterproofing; several fans are installed in the cooling system, etc. What type of lamp is it? Beads all need to be figured out.

The Difference Between Indoor LED Display And Outdoor LED Display

You may know that LED displays are installed and controlled in different ways, but the most critical difference is indoor and outdoor. This is the first and most important step in choosing an LED display, and it will determine how you choose an LED display in the future. So how to distinguish between indoor and outdoor LED display? How should we choose? 1. What is an indoor LED display? Indoor LED display refers to the LED display used indoors. For example, large-scale led display screens in shopping malls, large-scale broadcast led screens in stadiums, etc. These devices are everywhere. The size and shape of the indoor LED display is customized according to the buyer's idea. Due to the small pixel pitch of the indoor LED display, the quality and clarity of the LED display are relatively high. 2. What is an outdoor LED display? Outdoor LED display refers to the LED display used outdoors. Due to direct sunlight or long-term exposure to sunlight, the brightness of the outdoor LED display will be higher. In addition, since outdoor LED advertising displays are usually used in large areas, their area is generally much larger than indoor led displays. In addition, there are semi-outdoor LED displays for outdoor LED displays, which are generally installed at the door for information release and used in advertising media in retail stores. The pixel pitch is between indoor and outdoor LED display. It is often used in front of banks, shopping malls or hospitals. Due to the high brightness, the semi-outdoor LED display can be used outdoors without direct sunlight. Due to the good sealing performance, the LED display screen body is generally installed under the eaves or under the windows. 3. How to distinguish the outdoor led screen from the indoor led screen? For users who don't know much about LED displays, there is no other way to distinguish between indoor LED displays and outdoor LED displays except to look at the installation position of the LED display. I have summarized some differences between indoor and outdoor LED displays, which can help you better distinguish. 1) waterproof Because the indoor LED display is installed indoors, there is no waterproof measure. The surface of the outdoor LED display must be impervious to water. There are many outdoor LED displays installed in places that cannot be sheltered by wind and rain. Therefore, outdoor waterproofing is essential. 2) brightness Indoor LED display brightness is low, generally 800-1200cd/m2. Since there is no direct sunlight in the room, the brightness requirement is not very high. Outdoor LED display brightness is relatively high, generally around 5000-6000cd/m2. Since the outdoor is exposed to direct sunlight for a long time, it must have a high brightness to see a clear LED display in the sun. Reminder: The indoor LED display cannot be used outdoor, because the brightness is too low to see anything. Similarly, outdoor LED displays cannot be used indoor. Because the brightness is too high, it will hurt the eyes. 3) Pixel pitch The viewing distance of indoor LED display is relatively short, so there are corresponding requirements for the picture quality and clarity of the LED display. The pixel pitch of the indoor LED display is small. The smaller the dot pitch, the better the picture quality and clarity of the LED display. The viewing distance of the outdoor LED display is relatively far, so the picture quality and clarity of the LED display are not so high. The pixel pitch of outdoor LED display is generally larger. 4) Appearance Indoor LED displays are commonly used in places of worship, restaurants, shopping malls, workplaces, meeting spaces, and retail stores. Therefore, the usable indoor led screen cabinet will be smaller. Outdoor LED displays are usually used in large places such as football fields or highway signs, so the outdoor LED display cabinet is larger than the indoor cabinet. 5) Adaptability to external weather conditions In terms of adaptation to weather conditions, indoor LED displays are different from outdoor LED displays. The indoor LED display is installed indoors and is not affected by the weather. Therefore, in addition to the IP20 waterproof rating, there is no need to take any protective measures due to changes in external weather conditions, so there is no such function. The outdoor LED display is designed to fully adapt to various weather conditions. Outdoor LED screens are generally equipped with protective measures such as leakage prevention, dustproof, sunscreen, lightning protection, and waterproof. 4. Do you need outdoor LED screen or indoor LED screen? "Do you want indoor or outdoor" is a question that LED display manufacturers will definitely ask you, so before answering, you need to know what conditions the LED display you want must meet. Are you exposed to direct sunlight? Do you need a high-definition LED display? Is the installation location indoors or outdoors? Once these are considered, you can decide whether you need an indoor or outdoor display.

At the same time, DCI-certified cinema LED screens can also be used in a wider range of applications, especially in commercial digital cinemas and other public places, which is of great help to user experience and brand value. It is not easy for Cinema LED Displays to pass DCI certification. First of all, the capital cost is relatively high. Cinema LED Displays require the use of high-quality display devices, digital processors and other devices, and these devices are expensive. Therefore, for most small and medium-sized LED display companies, the capital cost of DCI certification may be very high. Secondly, DCI certification technical standards are very strict, requiring devices to have high resolution, color depth, and excellent image processing capabilities. In addition, applying for DCI certification for Cinema LED Displays requires a rigorous testing and review process, which involves professional knowledge and technical requirements in many fields, and takes a long time. This is not easy for those small and medium-sized Cinema LED Displays that need to be put into use urgently. However, once a DCI-certified movie LED screen means high quality, reliability, and stability, it can provide a better digital cinema experience. In addition, DCI certification is international and authoritative, and is generally recognized by commercial theaters, studios and distributors around the world. Cinema LED Displays that have passed DCI certification can also be used in a wider range of applications and have a higher market share. competitiveness and commercial value. For Cinema LED Display manufacturers, passing DCI certification is also a kind of technology and brand improvement, which can bring more business opportunities and market returns for enterprises. Therefore, it is of great significance for the Cinema LED Display to pass the DCI certification. It is worth mentioning that with the continuous advancement of social science and technology and the constant changes in market demand, the future development prospects of the Cinema LED Display market are still very broad. The penetration rate of the Cinema LED Display market will be further expanded. At present, Cinema LED Displays are mainly used in the high-end market and special application scenarios. With the continuous reduction of technology and input costs, Cinema LED Displays will be further popularized and applied in the low-end market. In addition, virtual reality technology is becoming one of the important forms of display in the fields of movies and games, and Cinema LED Display technology can provide a more realistic visual experience for virtual reality technology. In the next few years, the LED display industry will face a series of challenges and opportunities. The continuous updating of technology will make the market demand will also change constantly.
