Soon after the replacement of CRTs by liquid crystal televisions (LCDs), today's LED-backlit TVs have quickly become mainstream in the market at an alarming rate. While major manufacturers are accelerating the layout of the LED industry, Tsinghua Tongfang TV has mastered the development and manufacture of the most core LED epitaxial chips, high-end LED TV backlight modules, high-power LED device packaging and component design, LCD TV TVs, etc. In the technical field, and related industrialization, it has become a leading company in the field of LED TV in China.
Tsinghua Science and Technology seizes the LED opportunity
In 2004, Tsinghua Tongfang relied on the relevant technical strength of the LED industry of Tsinghua University to start researching the LED industry and technology, and actively assumed the national "863" project - "the key technology of industrialization of GaN-based blue/green high-brightness LED" Research and development and breakthrough.
"Semiconductor LED industry is known as the blue sky industry that can't see the dark clouds. After analyzing the relevant backgrounds of industry and market, we decided to seize the opportunity of LED industry development, through the breakthrough of semiconductor LED chip manufacturing, and through research and production. To turn Tsinghua technology into productivity." Wang Lianghai, vice president of Tongfang Co., told reporters that he has gained a competitive advantage by insisting on owning his own core technology.
"After two years of industrial development, the mass production of 14mil LED chips was realized in August 2006, and the mass production of 40mil high-power LED chips was realized in July 2007. The technical indicators of our mass production products are higher than the international mainstream products." Wang Lianghai said. Thanks to the mastery of core technologies, Tsinghua Tongfang began to focus on the global market, focusing on LED backlight lighting and architectural lighting, and transforming technological advantages into scale advantages and cost advantages, and participating in international competition.
Push LED TV composite upgrade
With the completion of the layout in the LED industry, Tsinghua Tongfang TV has fully launched LED TV and promoted the market competition from Internet TV to LED.
Since this year, Tsinghua Tongfang TV has first expanded and invested in four LED backlight module production lines in Shenyang. Subsequently, a new LED backlight module production line was built again in the high-brightness LED industry base in Nantong, Jiangsu. After the completion of the production line, it will have an annual production capacity of 2 million LED backlight modules and 2 million LED LCD TVs.
Wang Lianghai said that at present, Tsinghua Tongfang TV has realized the large-scale production of LED backlight modules between 19-inch and 57-inch. While satisfying its own use, it is still providing other brands in the industry. At present, Tsinghua Tongfang LED TV sales account for nearly 30% of its sales. "This proportion will be further expanded. We are further accelerating the elimination of CCFL TV and accelerating the popularization of energy-saving, environmentally friendly and ultra-bright LED TVs," Wang Lianghai said.
It is understood that in order to speed up the popularization of LED TV, Tsinghua Tongfang TV also carries network technology in LED TV, which makes products more connotative and competitive. According to the latest home appliances to the countryside bidding plan, Tsinghua Tongfang B91i, B91Ei, B90 and other series of LED TVs and B900I series network LED TVs won the bid in the whole country, which will greatly promote the LED TV in the Chinese market. universal.
