LED is an abbreviation for semiconductor light-emitting diodes. It was discovered in the early 20th century that the electroluminescence of semiconductor materials was discovered. The large-scale commercial use originated in the 1960s. In our daily life, LEDs can be seen everywhere. Every power indicator and instrument lighting around us is occupied by LEDs. Walking on the road, the bright colors of traffic lights benefit from it, and the increasing number of electrons on both sides of the road. The advertising screens are also LEDs.
LEDs are being used more and more widely, reflecting the pace of the information age. Wang Xiaodong, the founder of Dongcheng Intelligent Network Technology Co., Ltd., graduated from the Physics Department of Suzhou University. He studied light-based basic materials research at school. His career started with LED and made with a small LED. Big deal.
Stepping on the beat of the information age
In 1997, Wang Xiaodong first came to the business community, and his entrepreneurial planning did not leave the old business, intending to sneak in the world of LED. Today, Wang Xiaodong admits that in fact, the status of the LED industry at that time was not satisfactory. It is still quite risky to choose this industry. To survive, it is the key to invest in a large customer base. Drawing on the failures of some peers in the industry, Wang Xiaodong first selected high-quality customers such as banks.
Around 1998, when the financial market fluctuated greatly, deposit rates and exchange rate prices changed. Wang Xiaodong said that the money bags of the people have been drummed up, and the financial business of the bank has developed rapidly, and it is urgent to release a large amount of information to the public. However, at the time, the means of information release was still relatively backward, mostly by printing the posted paper to publish interest rate information. Wang Xiaodong found the right time, developed and introduced the first generation exchange rate display with adjustable digital numbers. The foreign exchange name and deposit category are the fixed frames. The numbers in the LED display can be adjusted and replaced at any time. This change, although the people only see a simple digital display, has actually taken a big step towards the rapid delivery and timely update of information.
Entering the Internet age, information updates are accelerating. At this time, Wang Xiaodong not only produced LED hardware products for releasing information, but also added technical added value to the products, and at the same time launched a supporting back-end management system - multimedia information release system. Wang Xiaodong made an analogy: the exchange rate is changing all the time, and it is definitely not possible to meet the demand by manual manual adjustment. A large amount of data and high accuracy requirements also test the personnel who release the information. By using the multimedia information publishing system, information distribution can be networked, centralized release, unified management, and real-time update. “One pulls the whole bodyâ€, a headquarters publishes and adjusts information, and all branches of the subordinates can receive and timely Update it. This will not only ensure the authority and accuracy of the published information, but also allow the people to understand the real-time market. The system was also well received after its launch, and 70% or 80% of the city's banks have adopted this system.
In recent years, people's demand for information has become more diversified, and diverse forms such as video and animation have become new favorites. Wang Xiaodong turned his attention to the high-density LED full-color display, which is another huge city. This year, Wang Xiaodong’s Dongcheng Company developed the highest density indoor LED display in China, reaching 48,000 pixels per square meter. Meters, while domestic LED displays can only reach more than 25,000 pixels per square meter. The higher the pixel density, the clearer the display effect of the screen, but the more pixels in the unit area, the higher the temperature, the uneven heat dissipation, and the short life. This technical bottleneck is also the domestic LED display. One of the reasons why it is difficult to break through. The technicians led by Wang Xiaodong broke through this technical problem and adopted a specially processed substrate material with good thermal conductivity and greatly prolonged the service life. After the “point-by-point debugging†level, the brightness and color of each pixel are adjusted to the best effect, and the LED display can be as clear as the TV screen.
