LED application case analysis

At the 6th China LED Industry Theme Summit Forum held by Gaogong LED, Zhang Jiuliu gave us a demonstration of its "LED Light Color Online Measurement and Control System Application Program". In this solution, the current application requirements for LEDs are mainly achieved by controlling and sorting colors and brightness. The sorting solution can be implemented from the following schemes: chip-based test sorting; test control and sorting in the packaging process; and uniform test sorting of the lamps.

Then Zhang Hui gave us a demonstration of the company's "Solutions and solutions for the application of solar LED lights on garden lights and landscape lights." Taking Xiamen Wuhu, Fujian Longyan, Hainan Sanya, Hubei Ezhou, Malay West as examples, the practical application examples from the existing solar LED lamps, the customer requirements, how to do the garden lights, solar panels The selection and application, the requirements of the lamps and their comparison with the mains garden lights, etc., explain how to apply the solar LED lights in the garden lights and landscape lights.

Then, Ye Rongnan, a professor-level senior engineer of the Fujian Optoelectronic Industry Association, demonstrated the “method of dynamic measurement of road lighting scenes”. It is pointed out that the results seen by the eyes are not consistent with the results measured; the brightness is not uniform even on the surface with uniform illumination. Taking the LED street lighting of Qishan North Road in Xiamen as an example, we detailed how to measure and measure the effect.

Finally, Le Shi Optoelectronics Technology (Shanghai) Co., Ltd. Wang Shiming will "based on high-power LED lamps and systems", taking Wuxi Lingshan Fan Palace LED lighting project as an example, introduced the characteristics of Wuxi Lingshan Fan Palace LED lighting project, from the system From the perspective of the luminaire, controller, layout, signal transmission solutions.

TFT LCD Display

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. .
