The Basic Knowledge of Led Display Screen

    1. Frame Refresh FrequencyThe time of picture being displayed in Led display screen gets updated in unit interval. Usually it is 25Hz、30Hz、50Hz、60Hz and so on. The frame frequency is higher, the continuity of the changed frame is better. 

    2. Refresh FrequencyThe time of picture shown in Led display screen gets repeated in each second. Usually it is 60Hz、120Hz and 240Hz. The refresh frequency is higher; the image on Led display screen is more stable. 

    3. Viewing AngleViewing angle is the maximum angle at which a Led display can be viewed with acceptable visual performance. It includes horizontal and vertical view angles.When the viewers move to the left side or the right side of the Led display panel, they will see the Led display brightness gets decreased; when the brightness is decreased to the half of the maximum, the viewer’s current position angle plus that in the opposite direction is called Horizontal viewing angle; vertical viewing angle can be measured in the same way.  

    4. Optimum viewing distanceThe optimum viewing distance is a distance where user can see all the content of the Led display screen completely, no color cast, at that place the image is clearest for viewer. The optimum viewing distance = pixel pitch / (0.3~0.8), this is an approx. range. For example, Led display P16mm, the best viewing distance is 20~54 meters. http://www.esdled.com/N_350.html

Obama’s worries while in Africa: even the LED display is made in China!

In the evening of July24, Air Force One with president of the USA Barack Obama on board arrived at the Nairobi international airport in Kenya. He is the first USA president who has visited his hometown while in office. Obama was warmly welcomed by the local people. On July 25th, Obama attended the Global Entrepreneurship Summit in Nairobi, the capital of Kenya.
Before departing for Africa, Obama was confronted with quite an embarrassing issue: while being interviewed for the BBC he was asked by the station’s chief editor for North America John Soulbel: “Haven’t the Chinese already conquered the African market? The African Union Headquarters which you just entered was built by the Chinese, the road you walked along was also constructed by the Chinese.”
What Obama might not have realized is that all the various LED display at the Global Entrepreneurship Summit which he had attended were made in China. And most them, especially the rental LED displays on stage, were all manufactured by a single Chinese LED display company: Eastar Electronic Co,.ltd. There was also one inconspicuous screen made by a different Chinese manufacturer. Even when coming home, Obama was unable to rid himself of this entanglement with China. If he knew all that, how would he have felt?
The LED displays shown at the Global Entrepreneurship Summit were from Eastar’s Mini Series. Mini Series is one of Eastar’s newest product lines. It is designed for the indoor rental market, and possesses state-of-the-art brightness and high greyscale. Even with the brightness as low as 200 cd, the color is still realistic and natural. At the same time, its high refresh rate guarantees the highest quality picture when filmed by a high definition camera. The Kenyan host would never dare disrespect the president of the USA. That’s why the best quality LED displays were chosen for the summit.
With excellent quality and extremely high cost performance ratio, Eastar Mini Series has conquered Asia Pacific, European, American and African markets. It has become the most popular LED rental display series. No matter whether it is a big music event or an important meeting, the Mini Series is everywhere. Because of their perfect display effect, the Mini Series small pixel displays have received widespread acclaim from clients.
