It is reported that the large-scale listed company focusing on LED lighting, Changfang Lighting, opened its brand strategic cooperation with Guangdong Advertising Co., Ltd. in July this year. The internal structure mechanism has been adjusted and optimized before December, and the current stage has gradually developed. Through a series of measures, through a variety of initiatives, increase brand communication, and comprehensively promote brand upgrade.
Throughout the current lighting industry, LED products market prices are mixed, quality is uneven, channels are mixed, and many factors are testing the market power of manufacturers. From the consumer's point of view, LED market demand is growing, where is the development of the market, whether the market will face a new round of reshuffle, is a problem that major manufacturers need to think about.
In the microscopically speaking, the measures for the LED advertising of the rectangular LED lighting can effectively enhance the attention of consumers and strongly support its brand upgrading strategy, laying a certain market foundation for the sustainable development of the brand. From a macro perspective, this initiative can play a benign industry demonstration role in the lighting market, and promote consumers to pay attention to LED products and further activate the demand of the consumer market. Therefore, we will promote environmentally friendly, green and energy-saving high-quality LED lighting products into thousands of households, assume the social responsibility of a corporate citizen, and achieve a double harvest of economic benefits and social development benefits.
Rectangular lighting said that placing outdoor advertising at the airport is the first step in its brand communication. With the deepening of the brand upgrade strategy, Changfang will always pay attention to the market dynamics, covering the consumer market in an all-round and three-dimensional manner, and finally let the brand image of Changfang LED lighting be deeply rooted in the hearts of the people, and let high-quality LED lighting products enter thousands of households. .
TFT LCD screens are characterized by good development, high screen, strong sense of layering, and bright colors, but there are also relatively power consumption and low cost. TFT screen technology legendary the development of mobile phone color screens. Many of them support 65536 color displays, and even have 160,000 color displays. With a very high screen TFT, the visual advantage is important.
Technical characteristics
TFT technology was developed in the 1990s. It uses new materials and new processes for fine semiconductor all-electronic manufacturing technology. It is the basis of liquid crystal (LC), inorganic and organic thin-film electroluminescence (EL and OEL) flat panel displays. It is a variety of films made on non-single materials such as glass or plastic products (of course also on the surface) through methods and chemical reaction forming processes, and a large number of micro-integrated circuits (LSIC) are produced through the processing of the films. Non-single crystal crystals can achieve cost reduction, which is an extension of traditional small integration to large area, function, and direction. Manufacturing TFTs that control the switching performance of pixels (LC or OLED) on large glass or plastic products has a higher technical content than manufacturing complete ICs on silicon wafers. The required production equipment and production technology surpass the production of large-scale integration of semiconductors, which is the luster of modern technology. The main features are:
(1) Large area: The first generation of large-area glass products (300mm×400mm) TFT-LCD-production line was put into production at the beginning of the nineties, and the area of eye glass has been expanded to 60mm×80mm in 2000), as well as 950mm×1200mm glass The design will also run.
(2) High integration: The size of the 1.3-inch TFT chip used for the projection of liquid crystal is one million for GA. The resolution is SXGA (1280×100×1280×1000×1280×1000×1280×1000×16.1 inch TFT screen amorphous film) 50nm, and TAB ON GLASS and SYSTEM ON GLASS technology, its IC integration, The technical requirements for equipment and supplier technology are more difficult than traditional LSI.
(3) Powerful function: TFT as a matrix selection solution provides the light valve characteristics of liquid crystal. TFT-LCD is the first Liquid Crystal Display in human history whose display quality exceeds that of CRT. The function will be more powerful, which is unmatched by traditional small integrated circuits.
(4) Design: Glass products and plastic products have fundamentally solved the problem of large semiconductors and opened up potential applications for the application of small semiconductors.
(5) Ingenious process: In addition to the use of vapor phase, chemical vapor deposition (chemical vapor deposition) MCVD (molecular chemical vapor deposition) and other processes to form films, laser flame technology has also begun to be applied traditionally, not only making amorphous films, polycrystalline films, but also Single crystal films can be manufactured. Can make silicon film, can also make other II-VI group and III-V group semiconductor thin film.
(6) Wide range of application fields. Liquid crystal display based on TFT technology is a rich industry in the information society, and the technology can also be applied to the rapid growth of thin-film organic electroluminescence (TFT-OLED) flat panel Display Screen shots. .
