SMD Indoor Full Color LED Display Modules need regular cleaning and maintenance, do you understand?
SMD Indoor Full Color LED Display Modules After a period of use, there will be dust, debris and other accumulation or attached to the screen screen body. These dust and debris attached to the screen body will affect the display of the SMD Indoor Full Color LED Display Modules and even affect the life of the display. SMD Indoor Full Color LED Display Modules need to regularly clean the dust, debris, then how to clean, you understand?
SMD Indoor Full Color LED Display Modules cleaning work is divided into before installation, after installation of the cleaning, the following Xiaobian to tell you about.
First, before the installation of cleaning, this time SMD Indoor Full Color LED Display Modules is a semi-finished product, LED module is not installed kit. At this time the cleaning to use a special washing plate water for cleaning, the LED module stained with some washing plate and then brush with a brush to speed up the decomposition of rosin and flux off, remove dust and impurities, this step cleaning By the SMD Indoor Full Color LED Display Modules manufacturer to complete.
Second, after the installation of cleaning, in order to clear the accumulation of dust and impurities after a period of time, we must first consider the purchase of better quality cleaning kit, the cost of cleaning fluid, including electrolytes, high purity distilled water, anti-static liquid, can be effective Clean the LED screen on the dust and other stains; some customers that the water can also, but also will not affect the SMD Indoor Full Color LED Display Modules, but the clean water is relatively poor, and clean the dust will be attached to the screen again ; Of course, if you want to save money, with water can also be better than those who are unknown to the cleaning fluid is much better; also need to pay attention to is that you can not spray the water on the screen, but to A little cleaning fluid sprayed on the cleaning cloth, and then gently wipe along the same direction, before cleaning, you need to pull out the power cord.
Summary: Regular cleaning and maintenance of the SMD Indoor Full Color LED Display Modules will not only extend the life of the display, but will also improve the quality of the SMD Indoor Full Color LED Display Modules.
SMD Indoor Full Color LED Display Modules Unground, leakage current not only may cause damage to the chip or lamp burn. If you use more than 20 power supply, the cumulative leakage current of 70mA or more, enough to cause damage to the leakage protector, cut off the power supply. This is why SMD Indoor Full Color LED Display Modules can not use the leakage protector.
If you do not receive leakage and SMD Indoor Full Color LED Display Modules are not grounded, the power supply superimposed leakage current will exceed the human safety current, 110V voltage enough to cause death. And ground, the power supply shell voltage close to the human body 0, indicating that there is no power between the power and the difference between the leakage current into the earth.
Summary: SMD Indoor Full Color LED Display Modules is the main component of the LED and driver chip, belonging to the collection of microelectronics products, LED operating voltage of about 5V, the general working current of 20 mA below. SMD Indoor Full Color The operating characteristics of the LED Display Modules determine the resistance to static and abnormal voltage or current shocks that are very fragile. We have to recognize this and give sufficient attention to the production and use of the process, to take measures to protect the SMD Indoor Full Color LED Display Modules, and power ground is SMD Indoor Full Color LED Display Modules the most commonly used a protection method. For product safety, the SMD Indoor Full Color LED Display Modules must be grounded.
RF wireless control: one end of the RF module connected to the control computer, the other end connected to the control card serial port, the computer installed driver, generate a virtual serial port, and send data through this serial port. It has easy installation and commissioning, data transmission distance of up to 300-1000 meters, the late use of no cost and so on. RF send, accept module, about 350 yuan a pair, support one-to-many send, that is, a send module to multiple receiving modules. But the method is also a number of shortcomings, the frequency band, the state allows the civilian not much, 433MHZ this batch, very easy to be signal interference, and this way the transmission rate is not very low, the baud rate can only be used 4800 Or 9600, is not recommended.
WIFI wireless control: through the installation of wireless routers or other wireless devices, and the user's original wireless network bridge, set up a wireless LAN, easy to network control card into the wireless network, the wireless network control. The method has the characteristics of no wiring, easy installation and debugging, fast data transmission. Equipment and price required, the bridge, 800 yuan or less; wireless router (in the application of the screen is best to choose the antenna can be changed, so you can effectively receive the wireless signal), the price of 100 yuan. The disadvantage is that the communication distance mainly depends on the bridge's gain capability, the wireless routing communication distance is relatively short, the wall signal is weak or no signal. Suitable for short-range wireless signal places. If your display area where there is a wireless signal coverage, it is more simple, and only need to be connected to the control card connected to the wireless router bridge to your wireless network, you can in the network any computer On the control SMD Indoor Full Color LED Display Modules.
