Body Water Solution For Your LED Display Screen

Recently, there will always be news on the Internet or on TV that rains have fallen in a certain area. Residents need to go boating. Extraordinary heavy rains not only cause a lot of inconvenience to people’s travel, but also may cause some LED display manufacturers’ warehouses. Water inflow causes water in the display screen body. In response to this phenomenon, what measures should LED display manufacturers take in the face of water in the screen body? Let’s explain the solution of water in the LED display screen.

First, use a fan or other tools to blow the LED display screen body completely dry at the fastest speed.

Secondly, the screen body that has been completely blow-dried is electrified and aged, the specific steps are as follows:Adjust the brightness (fully white) to 10%, and power on for 8-12 hours.

  •      Adjust the brightness (full white) to 30%, and age for 12 hours after power on.
  •     Adjust the brightness (full white) to 60%, and power on for 12-24 hours.
  •     Adjust the brightness (full white) to 80%, and power on for 12-24 hours.
  •     Adjust the brightness (full white) to *, and age for 8-12 hours after power on.

After completing the above steps, the LED display screen body will basically return to normal, but there are some points to note during the processing:

  • When water in the warehouse or water in the LED display screen is found, it should be dealt with urgently without delay;
  • Organize personnel to blow dry the LED display screen body that is in the water.
  • Do not put the LED display screen body that has been flooded into the air box, this will easily suffocate the LED lights.
  • When the water enters the warehouse, it may be necessary for the air box to enter the water. All air boxes should be exposed to prevent the water from evaporating into the LED display screen after the box is filled.
  • The failure of all incoming LED displays to affect the stability of the screen more or less. In the process of emergency treatment, the phenomenon of continuous dead lights may occur after the screen is powered on. This requires manufacturers Pay attention to observation at any time.
  • All the LED display screens that enter the water are in the flight case. For more than 72 hours, the screen is basically of no value for repair and needs to be handled with care.

In summary, in the face of the water ingress of the display screen, what is needed is the word “as soon as possible”. Use the shortest effective method to deal with it. The longer the time is, the greater the loss will be, so When you encounter problems such as water in the warehouse, you must act immediately.

With the development of the economy, it is common to install LED displays in shopping malls. LED power supply in shopping malls are generally used for brand promotion and product promotion, creating a good shopping atmosphere and mobilizing the atmosphere. The emergence of a new type of advertising media tool, the transparent LED display, provides more choices for shopping malls: transparent, cool, stylish, and full of technology.

Generally speaking, the LED display screen in conventional shopping malls weighs more than 30kg / ㎡, which requires high load-bearing capacity of the original building structure. It requires a large-scale steel frame structure during construction, which is time-consuming and labor-intensive. Bright is a dark piece, affecting the beautiful appearance of the mall building, blocking sunlight and sight, and affecting daylighting.

The transparent LED display is thin and beautiful, and has relatively low requirements for building load bearing. When it is not lit, it does not affect the aesthetic appearance of the building; high permeability ensures the lighting requirements of lighting structures such as floors between malls, glass facades, windows, etc. At the same time, it has good heat dissipation function and is easy to install and maintain. When playing advertisements, when designing the advertisement content screen, remove the unnecessary background color and replace it with black. You only need to display the expressed content, and the appropriate part does not emit light during playback, which is a transparent effect. This playback method is extremely Greatly reduce light pollution, can also reduce energy consumption LED Display, can achieve more than 30% energy saving than conventional LED display.

According to the characteristics of the mall and the actual needs of customers, the following is a reference for the selection of LED transparent screens in malls given by Orida:

  • Indoor use, protection grade IP43, no waterproof required, high protection grade can be customized for special places;     
  • The fixed installation method does not affect the original wall structure;   
  • High permeability, does not affect the shielding effect;
  • Consistent with the image of the mall center, remote control and operation can be realized.
  • The viewing distance is short, the display is required to be clear, and the pixel pitch is within 5mm.
      

The advertising content on the LED transparent screen can be changed at any time, displaying different advertisements around the clock;

High-efficiency optical fiber LED transmission system is adopted to effectively reduce the signal delay caused by long transmission distance and ensure the consistency of picture playback.

Shopping mall LED transparent screens are generally personalized according to the shopping mall environment and are coordinated with the installation environment. The front-maintained LED full-color transparent screens are selected for various modeling designs. The products with small LED cabinet sizes and ultra-thin, Surface-mount LED transparent screen with a dot pitch of about 10mm.

Like other items, LED display screens inevitably encounter such or other problems and precautions in use. When using a full-color LED Sign Parts, these eight problems may cause difficulties or affect the use of the large screen, and it can extend its service life.

01 Thermal Design

LEDs will generate heat during operation. Excessive temperature will affect the attenuation speed and stability of the LED. Therefore, the heat dissipation design of the PCB board and the ventilation and heat dissipation design of the box will affect the performance of the LED.

02 Mixed Lights

The LEDs of the same color and different brightness levels need to be mixed, or inserted according to the discrete design, to ensure the consistency of the brightness of each color of the entire screen. If there is a problem in this process, the local brightness of the large screen will be inconsistent, which directly affects the display effect of the large LED screen.

03 Design Current Value

The nominal current of the LED is 20mA. It is generally recommended that the maximum current used is not more than 80% of the nominal value. Especially for large screens with small dot pitch, the current value should be reduced due to poor heat dissipation conditions. According to experience, due to the inconsistencies in the attenuation speeds of the red, green and blue LEDs, the current values ​​of the blue and green LEDs are targeted to reduce the consistency of the white balance after long-term use of the large screen.

04 Drive Circuit Design

The arrangement of the driving circuit board driving IC on the large screen module will also affect the brightness of the LED. Because the driving IC output current is transmitted too far on the PCB, the voltage drop in the transmission path is too large, which affects the normal working voltage of the LED and reduces its brightness. We often find that the brightness of the LEDs around the large screen module is lower than the middle, which is why. Therefore, to ensure the consistency of the brightness of the large screen, it is necessary to design a distribution map of the driving circuit.

05 Control The Verticality Of The Lamp

LED Control System For in-line LEDs, there must be sufficient process technology to ensure that the LEDs are perpendicular to the PCB board when passing through the furnace. Any deviation will affect the brightness consistency of the LEDs that have been set, and color patches with inconsistent brightness will appear.

06 Welding Control

When the LED large screen is not lit, there is often more than 50% probability caused by various types of soldering, such as LED pin soldering, IC pin soldering, pin header soldering, and so on. The improvement of these problems requires rigorous process improvement and enhanced quality inspection to solve them. The vibration test before leaving the factory industry is also a good inspection method.

07 Wave Soldering Temperature and Time

It is necessary to strictly control the temperature of the wavefront welding and the furnace overheating time. It is recommended that the preheating temperature is 100 ° C ± 5 ° C and the maximum does not exceed 120 ° C, and the preheating temperature rise is required to be stable. The time is recommended to be no more than 3 seconds. Do not vibrate or impact the LED after the furnace is heated until it returns to normal temperature. The temperature parameters of the wave soldering machine should be checked regularly. This is determined by the characteristics of the LED. Overheating or fluctuating temperature will directly damage the LED or cause hidden danger to the quality of the LED, especially for small and round LEDs such as 3mm.

08 Anti-Static

LED large screen assembly factories should have good anti-static measures. Dedicated anti-static ground, anti-static floor, anti-static soldering iron, anti-static table mat, anti-static ring, anti-static clothing, humidity control, equipment grounding (especially foot cutting machine), etc. are all basic requirements and regular inspection with an electrostatic meter.

How Much Is A LED Display Design System Worth?

The nominal current of the LED is 20mA. It is generally recommended that the maximum current used is not more than 80% of the nominal value. Especially for large screens with small dot pitch, the current value should be reduced due to poor heat dissipation conditions. According to experience, due to the inconsistencies in the attenuation speeds of the red, green and blue LEDs, the current values ​​of the blue and green LEDs are targeted to reduce the consistency of the white balance after long-term use of the large screen.
