How to Clean a LED Panel Display?

Before and after the installation of a led panel, it needs to be cleaned, which is a very important link as it can avoid some bad phenomena in the displaying process. After running for a period of time, there will be debris accumulation which will influence the display such as dust. For this reason, periodically cleaning and maintaining the led panel display can extend its service life and improve the use quality. The senior technicians of Shenzhen D-King Photoelectric Technology Co., Ltd. have concluded many methods which are introduced below.



1. The cleaning of semi-finished led module
When the led modules are semi-finished products, special water for cleaning panel is need. Dip the led modules on some water for leaning panels, and brush them with hairbrush, to speed up the dissolution of colophony and the drop of scaling powder, and then remove dust and debris, and this procedure of cleaning is completed by the manufacturing company.

2. The cleaning of led electronic billboards after installation
After the led electronic billboards are installed for some time, there will be dust and debris accumulation, to ensure the displaying effect, it is necessary to clean the surface of the led display panel with clean water or clear water with washing-up liquid. When cleaning the surface, the workers must be very careful and shall not make the back side of the led module wet.

The Design and Installation of Outdoor Led Display Board

The main problems faced with outdoor led display board:

(1) The led board is installed outside, so that it is usually exposed to the sun and rain, and wind and dust, and the working environment is very bad. When the electronic billboard is soaked or seriously damp, short circuit or even fire will happen, thus causing failure and even fire disaster, which will lead property loss.



(2) The led sign may be hit by the strong electricity and strong magnetism caused by thunder.

(3) The temperature change of the environment is huge. When the led panel is working, it will produce a certain amount of heat, and when the environment temperature is too high and the heat dissipation is not good, the integrated circuit may not working normally or even be burnt down, which may cause the display system not to work normally.

(4) The audience of the led display screen is very large, so that the visible distance is required to be far, and the visible angle is required to be wide. Besides, the light change of the environment is also huge; especially that it may be directly shined by the sun.

Regarding the above special requirement, the design and installation of the outdoor led display board must conform to the following requirements:

(1) The display board and joint part of the display board and the construction must be strictly water proof. Besides, the display screen should have excellent drainage measure, so that the water can be drained away.

(2) Lightning arrester should be installed on the display panel as well as the building. In addition, the main part and case of the electronic advertising signs should maintain well grounded, and the ground resistance should be lower than 3O, so that the large current caused by thunder can be timely released.

(3) Ventilation device should be installed for cooling, so that the internal temperature of the display screen is maintained between -10℃ and 40℃. And axial flow fan should be installed on the upper part of the back of the display board for heat dissipation.

(4) Industrial-grade integrated circuit chip whose working temperature is between -40℃ and 80℃ should be used, so that the display panel can still be started even in winter when the temperature is very low.

(5) To make sure that the displayed content can be clearly seen from long distance when the environment light is very strong, ultra-high light led should be chosen.

How to Choose A Suitable Led Full Color Display?

Led full color display is generally divided into indoor full color led display and outdoor full color led display. Many friends may not know how to choose a suitable led full color display. Here the expert of D-King LED will introduce two methods to solve this problem.



1. The environment of the led display board.

Is it indoor, semi-outdoor or outdoor? As for different environments, the waterproof requirements will be different. For outdoor full color led display signs, the waterproof requirement will be high, and it should be over IP65. According to the environment, customers can be roughly certain the purchase range, which is outdoor full color led sign, semi-outdoor full color led sign or indoor full color led display board.

2. The distance from the optimum viewing position to the display board, namely, visible distance.
This is distance is very important, as it will directly determine the model of the display board that you will purchase. Generally speaking, the models of indoor full color led display board include P3, P4, P4.81, P6, P8, P10 and P16 and the models of outdoor full color digital signage include P6, P8, P10 and P16. As a general rule, the minimum visible distance is the same with the pixel pitch, that is to say, the optimum viewing distance of P10 full color led display screen is >= 10 meters. However, this method is only estimation.

On the other hand, there is a relatively scientific method, which calculates by using the pixel density per square meter. For example, the pixel density of P10 led full color led display screen is 10,000dots per square meter, and the calculation formula of the optimum viewing distance will be 1400/√10000/m², which is 14 meters, that is to say, the optimum viewing distance of P10 display board is over 14m.

Installation Requirement of Mobile Led Screen Rental

Mobile led screen rental displays information and products on a mobile car or mobile truck by using such technologies as LED technology, anti-static technology, low-temperature technology, vehicle electronics technology and anti-jamming technique. It is different from the common LED display board installed in a fixed place because the mobile led display is installed onto a truck or car which is always moving, so that it has some requirement for the installation.



1. In a car’s moving process, static electricity will be easily produced, especially in autumn; the high static voltage can reach thousands of volts. Without good anti-static precautions, the IC and LED light will be easily damaged.
2. The power supply on the car comes from the storage battery, so that when the car starts, brakes and stops, there will be high impulse voltage. If the power system is bad in quality, the display screen will be burnt down.
3. The luminance of the LED panel has attenuating property, and there will be 10-70% attenuation rate in one year. The LED display board with bad quality will be reduced half in luminance, for this reason, the content displayed on the display screen will be unclear to be seen.
4. In the north, a car is usually placed outside. The temperature in winter can reach minus 40 degrees centigrade and in summer the temperature can reach 60 degrees centigrade, which require that the power supply and display screen parts and components can work in a wide temperature range.
5. Suitable luminance. If the LED display panel does not have sufficient luminance, the displayed content cannot be seen in the daytime, so that it will lose the meaning of installing the display sign. However, if the led display screen is too bright in luminance, the car driving will be influenced.
6. The car is always in the moving motion, which has high requirement for the stability and reliability of the electronics.
