What is the cause of the flower screen phenomenon on the LED display?
Half of the outdoor LED display or the phenomenon of blurry screen is caused by the following two factors. 1. The outdoor LED display has no display or half of the display. In the LED display, only half of it is a common fault. Of the content that must be displayed, usually only part of it is displayed, which affects the advertising content and store brand image. Generally, there are many factors that cause this fault condition, such as: the internal power circuit line is aging, which causes the circuit line to be cut off, resulting in a part of the display module not receiving all normal power supply; or the LED driving characteristics are relatively poor, which makes it impossible to work well or Abnormalities often occur during work, resulting in the current supply cannot always be balanced. In view of this situation, it is necessary to dismantle and commutate the matching switching power supply route, so that the internal current power supply network of the display screen can be connected and supplied normally, and dismantle and replace the rated drive during unstable or abnormal operation, so as to ensure that the current of each phase is normal. Distribution, so as to obtain a smooth operation. 2. Part of the outdoor LED display has a false screen. One of the common faults is that a part of the LED display screen has a flickering fault. Because the customer is not a professional, the phenomenon of screen flickering often causes many problems to the customer. The main reason for this failure is: due to the long-term application of the LED display, the internal transmission data route is aging or the module board is caused. The quality of the drive is not good and unstable. At this time, the matching aging accessories should be removed, or the cause of the faulty drive of the module board should be repaired, so as to deal with the problem according to the problem, until the LED display is repaired and used normally.

Seven tips to improve the heat dissipation of indoor LED displays.
In practical applications, increasing the heat dissipation of the indoor LED display not only effectively improves the efficiency of the heat dissipation of the LED display, but also saves power, which is more conducive to improving the life of the LED display. 1. The LED display uses a fan to dissipate heat. Using a high-efficiency fan inside the lamp housing to enhance heat dissipation is a relatively common method, and this method has low cost and good effect. 2. The LED display uses aluminum heat dissipation fins, which is the most common way to dissipate heat. Use aluminum heat dissipation fins as part of the housing to increase the heat dissipation area. 3. Air fluid mechanics uses the shape of the lamp housing to create convective air, which is the lowest cost method of enhancing heat dissipation. 4. Surface radiation heat dissipation treatment. The surface of the lamp housing is treated with radiation heat dissipation. The simpler is to apply radiation heat dissipation paint, which can take the heat away from the surface of the lamp housing by radiation. 5. Integrated heat and heat dissipation. With the use of high thermal conductivity ceramics, the purpose of heat dissipation of the lamp housing is to reduce the operating temperature of the LED high-definition display chip. Since the expansion coefficient of the LED chip is very different from the expansion coefficient of our commonly used metal heat conduction and heat dissipation materials, the LED chip cannot be directly welded. In order to avoid high and low temperature thermal stress damage the LED display chip. 6. The LED display uses a heat pipe to dissipate heat. Using heat pipe technology, the heat is conducted from the LED display chip to the heat dissipation fins of the shell. 7. The thermally conductive plastic shell is filled with thermally conductive material when the plastic shell is injection molded to increase the thermal conductivity and heat dissipation capa

How to choose LED display screen correctly?
The LED display is mainly used to display text, display pictures and video screens and so on. When you are choosing an LED display, the first thing you need to consider is what your actual needs and use are. Plan the location of the LED display in advance. Here we mainly include the choice of size, as well as the use In terms of environment, control, etc., when you use the venue, some LED displays will have certain restrictions. If you choose blindly, it may cause the use of the effect to be not very good. So, how to choose LED display? First: first determine whether the wall of the LED display screen is a load-bearing wall. Before making the display screen, make sure that the wall where the display screen is installed is a solid wall. If it is not a solid wall, a nine-centimetre board wall can be used to install the display screen, so that it can be heavy. In the process of actual communication with customers, if some installation environments are very high, some installation environments do not have elevators, and some installation environments have complex ground assembly environments, etc., you need to choose competent personnel to understand this business and let manufacturers see The scene will be better. Second: Determine the area, length and height of the LED display. You can install this display according to your own design length and height, or you can design it according to the golden ratio of 16:9 and 4:3. The size is mainly designed according to the purpose of the wall you install. This size also depends on how big your venue is, what is the closest viewing distance in the first row of meters, and the size is closely related to the venue and model. Third: Determine the model of the LED display. (1) The indoor display models are P1.25, P1.56, P1.667, P1.875, P2, P2.5, P3, P4. The model determines the clarity, the smaller the number, the clearer. The larger the model number, the cheaper, the smaller the more expensive. (2) T

ROX Series high bays have been put into use in an ice-hockey stadium in Norway
In order for a better illuminating performance, ROX high bay was designed. It was widely used in factories, warehouses and stadiums. With the unique modular design and the powerful driver, the lumen of ROX can reach as high as 42000 lm. Meanwhile, a wide range of color temperature, angle and power can be selected based on different requirements. It also supports DALI so that the light can be more intelligent and more economic. The fine lighting is not only good for the performances of the athletes, but also a better visual enjoyment for the audience.
