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

How to choose high quality small pixel led display

With the continuous improvement of LED display technology, small pixel LED display become more and more excellent. The industry named led display which pixel under 0.8mm small pixel led display. What should we consider about when we choose small pixel led display?
Price. Due to the pixel pitch become small, the led lamps are more intensive. It requirements of small led display heat dissipation, electricity and circuit is higher than other pixel led display. Now, Small spacing LED display technology is still in the development period, not very skilled, resulting in the small distance LED display price is very expensive. But with small pitch LED display technology is more and more skilled, more and more high capacity, the price will be declined. Just like the cellphone, the price is very expensive when it come out but when the cellphone flooded in the market the price is not so expensive.
From the maintenance aspect, although the LED display life is very long, the lamp is more, and the thickness requirements of indoor is lower than outdoor, resulting in the cooling effect is not very good, prone to failure. This situation is hard for small led displays maintain but now there is solution, front maintain led display. Attention should be paid to the purchase and application of small pixel led display
The brightness area ratio of LED display is the ratio of each pixel of luminous surface to the pixel of whole LED display screen, and led display is arranged by discrete pixels, pixels and pixels are very different. Some viewing effect is not good in very close distance and uneven brightness will have granular things. If the light source is in very small pixels, the brightness index of a pixel is very high; it will cause a strong visual impact.
Flat LED display is recognized in the industry ‘TCO’ 99 standard requirements, LED lights can not less than 50%, but now many of the LED display on the market cannot meet the requirements
The TV low-pass filter cut-off characteristics also affect the proper shooting distance of the LED display screen with different filling coefficients. The attenuation of small filling coefficients is more than large filling coefficients, so it required in long distance to take a photo. If the low-pass filter pass band is 4MHz, and the high frequency attenuation characteristic 12db/ octave, then the shooting distance of the fill factor 25% is more attenuated 1.15db than the fill factor 50%, and the shooting distance needs to be increased by about 10%. The increase of fill factor is the wider application of LED display color difference is more ideal, perfectly solved the dazzling problem, now the LED display creation conditions are also getting better and better.
It is aims to achieve high-definition of small distance LED display, enter the home appliance industry. Now the LED display is used as municipal project l and commercial media. If you enter the home appliance industry and sells to every family, which is undoubtedly a display revolution

Hai sheng engineers analyze LED display control card FAQ

Hai sheng engineers analyze LED display control card FAQ
1. How to determine whether the control card is working properly?
After the control card is powered on, observe the power indicator first. The red light indicates that the 5V voltage has been connected. If it is off, turn off the 5V power supply immediately. Check whether the 5V working voltage is connected properly, whether it is overvoltage, reverse connection, failure, output short circuit, etc. Please use a separate 5V power supply for the control card. If the red light is not on, repair it.

2. When the control card is normal, why is there no display or abnormal brightness?
After connecting the control card and display driver, the default is 16 scan. If there is no display, please check whether the data polarity and OE polarity setting in the control software are correct. If the brightness is abnormal, one line is particularly bright, indicating that the OE setting is reversed. Set OE correctly.

3. When the message is sent to the control card, the system prompts “An error has occurred and the transmission failed.”
Please check whether the connection of the communication interface is correct and whether the jumper on the control card jumps in the corresponding level position. The parameters in “control card setting” are correct. Also, if the operating voltage is too low, please use a multimeter to measure the voltage above 4.5V.
4. Why does the display screen not display properly after the information is loaded?
Check if the scan output selection in the “Control Card Settings” is correct.

5, why 485 group network communication is not smooth?
Please check whether the connection mode of the communication line is correct, and connect the communication lines of the various screens together to the computer interface. This will generate strong reflection waves and cause serious interference to the transmission signal.
