Optokingdom engineers share tips on using LED displays to increase life!

cabinet front maintain1. If the LED display has damaged parts, it should be replaced in time, especially the small parts of the steel frame structure.

2. In the early warning of natural disasters, it is necessary to check the stability and safety of each component of the LED display and handle it in time.

3. Regularly maintain the surface coating of the product and steel structure solder joints to prevent corrosion, rust and peeling.

4. Cleaning and maintenance of the LED module, use a soft brush and water to scrub the dust accumulated outside the LED tube.

5. First check the connection of each line in the distribution box for rust or looseness. The entire power supply system also needs to be checked twice a year.

When the led display is playing a program, the module of the cabinet is lacking in color.

图片1(1) Check if the signal line between the bright module and the colorless module is loose.
(2) Insert one end of a long signal cable into the receiving card and the other end into the missing color module. 1. If the display is normal, the previous module output is faulty. 2. If there is still a lack of color, it means that the module input is faulty and replace its module.

What is the reason for the black screen on the led screen?

2. Check if the serial cable connected to the controller is loose or disconnected. (If the screen changes to black during the loading process, it is likely to be caused by this reason)

3. Check if the HUB distribution board connected to the main control card is connected tightly. You can not plug in the opposite direction.

Indoor Led display cannot be used in outdoor environments.

1, indoor Led display brightness is generally less than 2000CD/sqm; outdoor Led display brightness is greater than 4500CD/sqm.
2, indoor Led lamp do not have UV protection, use in sunlight will only shorten the life of LED. Indoor Led lamp are used at high temperatures to speed up the speed of decay.
3, indoor Led cabinets, modules, wires are designed and produced in accordance with indoor standards.cabinet front maintain

Shenzhen hia sheng specializes in producing LED display for 11 years.

Optokingdom engineers share SMD, 4in1, COB, GOB, and AOB processes.

SMD package: Single or multiple LED chips are soldered to a metal bracket with a plastic “cup” frame. Liquid epoxy resin or silicone gel is potted into the plastic frame, then baked at a high temperature, and then cut into individual surface mount packages.


4in1 package: There are four basic pixel structures in a package structure, which is essentially four “light beads” synthesized by 12 RGB–LED chips.

COB package: A bare chip is adhered to an interconnect substrate with a conductive or non-conductive paste, and then wire bonding is performed to realize electrical connection.GOB package: (Glue on board) GOB uses an advanced new transparent material to encapsulate the substrate and its LED package unit to form an effective protection.

AOB package: (Admixture On board) AOB is a process arranged in the production process of surface-mount LED display. After the SMT process is completed, a film of a polymer material is coated on the surface of the lamp board and protected by nano-coating.

Does the outdoor LED display need to be cleaned? Yes, use a soft brush to scrub.

After the outdoor LED display works for a certain period of time, there will be dust accumulation on the surface of the LED module to affect the display effect. Regular cleaning and maintenance of the display can prevent the LED display from being unclear during playback, mosaic phenomenon and color cast during black screen, and can extend its service life and improve display. Use a clean water and detergent liquid to scrub the surface of the LED display.

Optokingdom shares the reason why outdoor advertising preferred LED display advertising?

Traditional outdoor advertising model (such as single-column advertising, light box advertising, bridge advertising, three-sided advertising, etc.) with the advancement of technological innovation, the traditional industry upgrade. In the past, the old advertising model no longer meets the needs of market users, and traditional outdoor advertising has caused visual fatigue. Outdoor advertisers have to follow the pace of technology, so there is an outdoor LED display advertising, then LED display advertising is better than traditional outdoor advertising in what aspects?

The traditional advertisement publishing information is not as convenient as the LED display information. Every time a traditional advertisement is published, the entire advertisement has to be redesigned and replaced, and labor costs are required, which is time consuming and labor intensive. LED display ads only need to be connected via computer cable or wireless communication (wifi, 3G, 4G), simple settings in the computer, you can use to publish advertising content, convenient and fast.

The traditional advertising form has limited content and cannot fully express the advertising content; while the LED display advertisement, the operator and the publisher can update the LED display advertising content at any time, only need to operate and control the computer, and the updating process is not restricted by other external conditions.

Traditional advertising can only be presented in the form of pictures, lacking creativity and making people forget. LED displays are often more appealing to the public in the form of intuitive, vivid, visual video and 3D effects. They are usually located in public places, transportation routes, plazas, commercial buildings, shopping centers, etc. It is wider than the traditional media audience and has a better communication effect.

Shenzhen Haisheng Optoelectronics has 10 years of experience in R&D, production and sales of LED displays. Our company’s advantages in outdoor products are PH10, PH8, PH6, PH5, PH4, PH3, etc. For more products, please visit our website.


HSTV engineers share How to do emergency protection after led screen is watered

With led screen widely used everywhere, people know the function and outstanding advertising effect of led screen, but not all people know how to solve when there is maintenance work. Here we talk about how to protect the led screen when it is watered.

1.dry the led screen by fans at the earliest time

2.turn on the led screen with below detail steps
1): set 10% full white balance, power on 8-12 hours
2): set 30% full white balance, power on 12 hours
3): set 60% full white balance, power on 12-24 hours
4): set 80% full white balance, power on 12-24 hours
5): set 100% full white balance, power on 8-12 hours

3.led screen will work normally after above mentioned steps, but there are a few points that we need to pay attention to

1)don not put the led screen with water in the flightcase in case the led lamps will be braised to get broken
2)If led screen is restored in warehouse with water, flightcase is probably affected also, you need to dry the flightcase under strong sun and 100% make sure it is dry so that you could move the cabinets into the flightcase
3)During the white balance test, there will have dead led, it is normal
There is no repair value if watered led screen in the flightcase for more than 72 hours, the stability will be influenced much, buy a new led screen is more practi
