These innovative technologies will transform the SMD LED industry within 5 to 10 years.
Material ESW sharing: Based on this, the yield of template graphics can be tested using a computer vision system card to receive data on the screen, demonstrating the advantages of graphics and images to help improve the display effect of the display screen.
Solution: You can make a judgment based on experimental data, and this adjustment method is a "low dimensional load, high wear resistance, and low power consumption" method.
Provide a main board and multi segment drive solution, with a single beam using PCIIO ports and a bimetallic size of 1516mm. The main power supply and bimetallic plate are independently connected. This method corresponds to: the first section of the driver consists of four sections, and the dual platform outputs a group of six and seven sections; The second section of the driver consists of five sections, and the bridging sections 5 and 6 output one group on the same chip; The circuit board has 5, 6, 7 segments, 15, and 11 output plug-in segments. All parts can be left with messages, code communication, power indicator light, outdoor lighting engineering, and divided into three levels.
The power amplifier provides three main conditions and corresponding indication functions, such as flashing power indicator light causing power failure and short assembly cycle (employees can adapt to parameter testing); When a malfunction occurs, the cause should be identified (parameter replacement testing).
When there is a malfunction in the LED of the 8-segment LED module, we should first effectively inspect the components, as shown in Tables 2A1 and 0012, to check the quality of the components until there is no damage. If there is a problem, check if the communication cable has fallen off. Check if there are any issues with the controller (data distributor), the G connection distributor is faulty, and the register (data cable) is not faulty. If there is a problem, check if the communication line is faulty. If an error occurs, check if there is a problem with the communication line. Check if there are any issues with the controller (data transmission system) and if the communication port is malfunctioning.
We organize regular inspections, personnel conduct annual inspections, and ensure that the goods are in good condition. If it is found that it cannot be used normally, check the environmental capacity meter, use a measuring instrument, distributor, etc., and conduct calculation data testing. If there are no issues, check the power supply system of the display screen to determine the specifications or data list. If there is such a problem, you can check whether the power supply of the components is normal. If there are no issues, check the controller (connector) for any issues, and check the internal fuse of the display screen for blown fuses. Check the controller (connector) for reasons such as faulty soldering, looseness, etc.
Before contacting the service personnel for confirmation, we must first check the power supply of the operating system to ensure its performance, otherwise it may cause harmful waste.
Before "installation", we must first check the three-phase power supply of the city power, because the three-phase power supply of the city power is an important component of 220V and CCF capacitors. Recheck the power supply system of ordinary high-rise building circuits.
According to the specific situation of our three-phase power supply, the three-phase power supply must be determined as the three-phase power supply. Generally, the three-phase power supply condition is 20~22 mA. The three-phase power supply is damaged or has no current or virtual power.
In such a situation, we must first consider the safety of returning machines or bidding projects.
