CCTV "News Network" new studio will be put into use in the first half of this year, who seems to be "high on the" new studio LED background screen in the end who made it? Will it be an LED company in the A-share market? "No, no, not" Perhaps the most likely of the A shares is Liard. The company announced in July last year that Jebsen shares won the bid for CCTV foreign language channel studio window background screen and foreign language channel studio low resolution LED background wall two projects, the total amount of winning bid is 14.1094 million yuan. The LED screens of Jebsen are being provided by Liard. This time? "No". Li Nan, secretary of the board of directors, denied this speculation. Which company would that be? The company expressed uncertainty. Zhou Ming Technology, one of the major suppliers of LED displays in the Sochi Winter Olympics, also denied the supply and did not know which supplier it might be. On the upstream side of the enterprise, the long-party lighting that was packaged at the company also denied being a supplier. Or for Lighthouse However, some insiders revealed to reporters that the supplier may be Lighthouse (Lightlight Technology), an LED display manufacturer established in Hong Kong. According to previous media reports, Lighthouse was established in 1998 and is considered "old" in LED displays. Its current business scope covers the whole world. The F1 Championships around the world, the outdoor arc billboards of the Coca-Cola Company of Piccadilly Circus in London, and the LED display above the main entrance of the Shanghai Railway Station are all products. However, if it is true, the "very dazzling" studio of "News Network" and the fate of A shares seem to be waiting. Among the A-shares, it seems that only Alto Electronics has passed on it and said that it wants to acquire it. Other companies have not yet been connected. The spacing of 2.9mm is "not the top" in the industry? And if you look at the 2.9mm small-pitch display that the media called the "bright spot", some insiders say that this is not the top in the LED industry. At present, the technical range of LED small-pitch products of domestic manufacturers has already exceeded this level. The distance between Liaide and Lianjian Optoelectronics has exceeded 1.6mm. Zhouming Technology has developed a macro-clear display with a pitch of 1.0mm. Screen. However, some analysts pointed out that the smaller the spacing, the higher the LED screen and the more expensive the price. Generally, the pitch size is geometrically related to the product price. At present, the LED display with a pitch of 2.5mm can be 80,000 square meters. If the distance is small, the price will be too high. This may not be the choice of CCTV. The reason for smaller pitch products.
An electrical appliance used to protect electrical equipment from high transient overvoltage hazards and to limit the duration of continuous flow.This term includes any external clearance necessary for the normal functioning of the appliance during operation and installation, whether or not it is a unit as a whole.
Surge Protector, also known as lightning arrester, is an electronic device that provides safety protection for all kinds of electronic equipment, instruments and communication lines.When the electric circuit or communication lines or for outside disturbance suddenly produce peak current in voltage, surge protector in a very short time conduction tap, to avoid surge damage to other devices in the circuits.[1]
Surge protector, suitable for ac 50/60 hz, rated voltage 220 v to 380 v power supply system, the indirect lightning and thunder and lightning directly affect transient over voltage surge protection, or other applicable to the family home, the third industry and the surge protection industry requirements.
