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. .
Since October 1 this year, China will officially launch the incandescent lamp elimination plan, and gradually phase out the import and sale of ordinary lighting incandescent lamps according to the power level. Once incandescent lamps are banned, daily lighting will be transformed into new light sources such as energy-saving lamps or LED lights. Especially LED lights, due to their advantages of energy saving, environmental protection and low carbon, are the general trend of future lighting. In the growing LED lamp camp, a rechargeable LED bulb, due to its advantages of energy saving, versatility, and emergency performance, will become a new choice for daily lighting in China.
Mature rechargeable LED bulbs in overseas markets are popular
Rechargeable LED bulbs, as the name suggests, in addition to the LED bulbs are energy efficient, durable, low carbon and environmentally friendly, can also be charged, when the power failure, the bulb can continue to light. With the increasing awareness of energy conservation and environmental protection and the continuous improvement of the products themselves, this rechargeable LED bulb has been relatively mature in overseas markets and has been welcomed by more and more families, especially students.
Because it can be installed on any indoor lighting fixtures such as desk lamps, chandeliers, etc., and its rechargeable and easy to carry features, rechargeable LED bulbs are popular in Europe, America, Australia and other countries, becoming a choice for indoor lighting tools and tourism and field in foreign countries. The preferred product for outdoor lighting such as camping.
At the same time, the rechargeable LED bulb can also solve the problem of students' night reading well, and enjoy the convenience brought by it.
BOE is the first to introduce a rechargeable LED bulb with you to enjoy "Happy Three Hours"
In order to meet the growing domestic demand, this year's high-tech enterprise BOE (BOE) plans to launch BOE rechargeable LED bulbs, representing the most cutting-edge technology and innovation in the world, and promoting China's daily lighting and international standards.
BOE rechargeable 5W LED bulbs have the advantages of safety, energy saving, long life and easy operation. When used on general lamps, they can replace 25W incandescent lamps, saving 70%, and have built-in lithium batteries (can be recharged more than 500 times) In the event of a power outage, the light bulb can continue to be used for 3 hours, so it will become a must-have for families, especially students, during night reading. At the same time, the neck of the bulb can be telescopic, and the handle can be used as a flashlight. It is also the best companion for tourists and campers.
According to the relevant person in charge of BOE: The company's BOE rechargeable LED bulb will officially enter the "BOE Lighting Flagship Store" in Tmall Mall in early October, as the only official authentic Tmall for the majority of consumers. At that time, even if there is a power outage, we can easily pass the "happy three hours" brought by the BOE rechargeable LED bulb.
In the last countdown of incandescent lamps entering the "lights off", BOE responded to the needs of the times, using the LED lighting characteristics, launched BOE rechargeable LED lights, and strived to be the "post-incandescent era" domestic rechargeable LED bulb pioneer. At the same time, it also reminds people: As a new member of the LED light bulb camp, rechargeable LED bulbs will become a new choice for people's daily lighting life.
