On the parade of Tiananmen Square on the 60th anniversary of the National Day, there was a detail that left hundreds of millions of viewers with an aftertaste. That is, four large-scale LED displays with world-class technology on both sides and opposite sides of the Tiananmen Gate. The LED display on the east and west sides of Tiananmen Tower is 367 square meters each, and the LED display on the east and west sides of the Monument to the People's Heroes is 250 square meters each. In Shenzhen, there are three companies involved in the production and installation of the display screen, taking on most of the most critical work. In yesterday's high-tech fair pavilion, Baoan District Enterprise Shenzhen Liard Photoelectric Co., Ltd. and Shenzhen Zhouming Technology Co., Ltd. also invited their core technologies into the pavilion to let the general public take a quick look.
The person in charge of Shenzhen Liade Photoelectric Co., Ltd. told the reporter that Liard was responsible for the production, installation and system commissioning of three of the display screens. The three screens are located on the west side of the Monument to the People’s Heroes and the east and west of Tiananmen Tower. On both sides, the total area is over 1000 square meters. He introduced that these three screens all use the world's most advanced technology, especially the two LED screens on the east and west sides of the Tiananmen Gate. The single screen area is close to 370 square meters. Each screen consists of 299 boxes. Each screen has more than 1.4 million pixels, and dual-insurance backup settings are used on the circuit and video control processing system to ensure that the event is live. The display energy consumption is reduced by 15% to 20%, and it is also waterproof, lightning-proof, and flame-retardant. Production, installation and commissioning are the most important parts of the project, accounting for 95% of the total project. The same scale project originally required 60 days, but more than 300 employees of Liard completed the battle in one month.
The production and installation of the display on the east side of the Monument to the People's Heroes was completed by Shenzhen Zhouming Technology Co., Ltd. and Dongguan Qinshang Optoelectronics Co., Ltd. This large-scale LED display is located in the middle of the Monument to the People's Heroes and the Tiananmen Gate. It is 800 meters away from the Tiananmen Gate Tower. The total area is 250 square meters. The number of high-quality LED display devices is more than 3 million. Remote synchronization control, high-definition digital display, quality acceptance Strictly tested, it has attracted worldwide attention. The party and state leaders who participated in the National Day military parade can see this large LED display from the front of the Tiananmen Gate. During the National Day, Zhouming Technology's large-scale LED display was a highlight of a series of major events in the National Day military parade and Tiananmen Square.
The reporter learned that the LED industry is a key industry supported by Shenzhen. There are more than 740 LED upstream and downstream enterprises, accounting for 44% of the country, with an annual output value of more than 16 billion yuan, accounting for more than 60% of the country. Many leading companies in the industry have invested heavily. Shenzhen industry insiders said that China's LED industry has made great progress, but LED high-end display devices have long been monopolized by imported products.
