When the typhoon hits, how to make the protection of LED display?

When the typhoon hits, the LED display can’t display properly,  in order to get ready for such situation, the expertise engineer of HSTV gave a series of suggestions, and pointed that the most important method to protect LED display is completely turn off the power! However, this is just one step, the more important is make ready for the anti-lightning, anti-water schedule in the early stage.

Anti-lightning program

1、 The protection against direct lighting

Take a 20 meters long  LED display for example, if installing a lightning rod long for 7, 8 meters, it will cause the installation and maintenance difficulties, so the design of two lightning rod each for 3 meters high with installing onto the steel structure away 5 meters from the two sides of display, and being connected by welding with the steel structure will completely make the enough protection of display.

2、The protection against inductive lighting

1) The power anti-lighting

Install a SGM-B in the distribution box of display screen.

2) The signal anti-lightning
Make the series connection of the display and computer’s signal line and a web signal anti-lightning device with RJ45 connector, and make sure the anti-lighting device more close to the display.
Of course, typhoon is often accompanied with heavy rain, how will make the solution if the LED display is poured into water in the warehouse?

Solutions against anti-water

1.Use the draught fan to dry completely the watering LED display in the shortest time.

2.Keep the display screen powered-on and aging after drying, the steps as follows:

a) Adjust the brightness(all white) into 10%, and keep powered-on and aging for 8-12 hours.

b)Adjust the brightness(all white) into 30%, and keep powered-on and aging for 12 hours.

c) Adjust the brightness(all white) into 60%, and keep powered-on and aging for 12-24 hours.

d) Adjust the brightness(all white) into 80%, and keep powered-on and aging for 12-24 hours.

e) Adjust the brightness(all white) into 100%, and keep powered-on and aging for 8-12 hours.

Through the above solutions, the LED display will return back into normal, but there’ re several points to note:

1.Not put the watering LED display into the flight case, thus wil turn the LED lights bad easily.

2.When the warehouse is watered, make the all the flight cases exposed under the sun for quite a long time to avoid the moisture evaporated into the led display after assembling the cabinet.

How LED defeat the threatening OLED and hold the market share?


In recent years, OLED has become a term with quite high frequency appearing in relevant reports in display industry. This new term makes many people confused as the difference between OLED and LED lies in a single word. Although OLED is mainly used in some applications with small size screens, like mobile phones, in the field of large screen display, some enterprises has already felt threatened by it. Regarding the seemingly upcoming OLED, can traditional LED enterprises defeat it and hold a high market share as before?

First of all, there are some conceptual differences between OLED and LED. As the word LED shows, Light-emitting diode is the pixel display of LED, and the color LED display consist of three basic light emitting elements including red, blue and green LED, with dot arrays configurations. LED modules, control system and power supply system comprise a complete LED display,which emits lights with different colors by turning on or off the LED lights and then forms the images.

However, OLED works totally different from LED display. OLED, short for organic light-emitting diode, emits lights by driving the organic thin films through electricity, whose emitted lights can be flat colors like white, blue, red, green and so on, or OLED can also achieve a full color effect.

In short, OLED differentiate from LED in emitting ways, materials. Yet both LED and OLED are self-luminous. What should be mentioned is that flexible OLED can be bent, curled and even folded.

How OLED can threaten the position of LED in the display market? Speaking of OLED, people always link it to LCD. Yet even LED is gradually taking LCD, the upcoming OLED will also bring challenges for LED display industry. As one of members in LED display industry, HSTV thinks that traditional LED display can maintain its market share with some countermeasures.
