The earthquake in Japan in the northeast, we know that most of the liquid crystal industry related plant distribution in the south and west, are far away from the point of view of geographical distance from the source, does not seem to influence is very big, but to know LCD panel production belong to precision process, even minor earthquake, is also likely to affect the production equipment.     Panasonic, sharp panel factory are distributed in southwest Japan, far from the earthquake center, relatively little damage, no plant and equipment damage, but the world's top two major glass manufacturers and Asahi corning relatively closer from the earthquake zone, the loss is evaluating the earthquake has been preliminary discontinued.   Sharp, Sony to vote heavily built billed as the world's first LCD panel plants factory, located in Osaka city, far from the source, and in manufacturing has fully considered the factors of the earthquake, using a variety of anti-shock measures.Before sharp in Japan issued a statement on its web site, said after the inspection, the factory has not been lost, now factories, Guishan main plant normal operation such as the eight generations. Another big giant Panasonic panel is the most important, battery plasma display factory and not too much of a loss, now everything is normal, but unfortunately, Shigeru chiba prefecture in Japan original LCD panel factory suffered a loss, but "no fire or building collapse phenomenon".Panasonic is not sure when the factory can resume production, fortunately, Panasonic and factory located in Himeji city in the west of the panel, adjust the capacity configuration should not be too big gap.   Although panel factory did not suffer a great loss, but also not rest easy on behalf of the entire LCD industry, we know that Japan besides LCD panel plants with high generation, what is more important for global provide a large number of upstream components, including the semiconductor wafer, glass, etc., and make the drive circuit is the LCD panel and the necessary accessories.It is understood that the world's top two corning glass manufacturers and xu glass glass factory has certain degree of loss, the corning convenient says the problem is not big, will soon resume production.But luck seems to sent some, Asahi meters in Yamagata prefecture, located in jersey city, engaged in small and medium-sized LCD Glass processing business of AGC Display Glass m jersey factory buildings and equipment are not lethal damage, is gradually resume production.However, as part of the cooperation of the company processing products company building and equipment damage serious condition, production is still not clear when can fully recover.  

Pursuant away from the radiator heat method, thermal method of splicing LCD screen is divided into automatic cooling and passive cooling, the former is the result of fans and other cooling equipment compulsive fin heat emitted away, the latter is the result of heat sheet as a large-screen display merchandise heat source natural source Phi hair into the air.   Practical operation, the automatic cooling methods can be divided into air cooling, liquid cooling, heat pipe cooling, semiconductor refrigeration, chemical, refrigeration, etc., having a high power dissipation, the devices are small advantages; passive cooling method, cooling effect fin size is proportional to the primary use of the space in the device does not require a fever or not the amount of heat in parts.   Generally speaking, in order to properly use the LCD screen splicing, adhere to the best temperature between 0 and 42 degrees. Practical use of the LCD screen used in the mosaic indoor environment, the choice will be the first automatic contrast efficient cooling method, a user can trade through the use of air conditioning equipment to control the temperature, the temperature control is usually between 25 and 26 degrees.   LCD splicing screen in addition to the heat, the need to dust!   LCD splicing screen in the operating state, the temperature of the lights can occur up to 1000 degrees, and a lot of equipment inside the unit operating temperature is 70 degrees Celsius, the high temperature environment will become more severe form, in this case, the primary occupation user air-cooled heat mode selection. It is worth noting that although this method will reach a certain cooling effect, however, during operation, easy to dust in the air into the device. Thus, in the cooling process in the LCD screen splicing, other than physical cooling operation, but also pay attention to timing devices dust.   Also, to remind you! After splicing screen LCD lamp service life is limited, the lamp life expires, if continued use of explosion is very simple, and therefore, the use of high temperatures in the summer, the user must pay attention to the bulb's view, the use of a period of time, if the light bulb brightness greatly reduced, that is, the warning lamp service life expires.

In the large-size LCD display industry, if the seamless likened to a "appetizer", the 4K display is definitely considered "signature dish." The large display screen in order to achieve a fine display, high resolution is an essential element, which is the subject of much favor 4k display key. It is reported that, on the film of Science and Technology in May launched a new fifth-generation multimedia touch one 4K and 4K intelligent liquid crystal display system widely recognized in the industry, its sales have been high.     DDW fifth-generation multimedia touch one of its 4K equipped with a variety of sizes, with a resolution of 3840 × 2160 of 4K / UHD IPS ten-point touch screen, the pixel density of up to 185PPI, viewing angle up to 178 °, able to cover 100 % of the sRGB color gamut, showing us a more complete, accurate, rich and vivid colors, whether text read or watch videos, will give us a visual feast.   4K, having a standard resolution of a new generation of Hollywood. DDW biotechnology research and development personnel, we are at home watching it differs from the so-called high-definition television (1080P, 1920 × 1080 resolution), but also different from traditional digital cinema 2K resolution large screen (2048 × 1080 resolution), but It has a 4096 × 2160 resolution, ultra-fine screen. The analogy is simple: you are at home to see high-definition television screen 207 million pixels, whereas in the conventional digital cinema to see 221 million pixels picture in 4K cinema, to see 8.85 million pixels high clear picture.   DDW this 4K screen provided by LG, the dramatic increase in the number of pixels can be achieved obviously more delicate display, you will find a normal viewing distance is difficult to find the edges or corners of the pixel application icon, the overall color performance is more prominent. Technical staff found that if not a video enthusiast, noted that it may be difficult to enhance the color area, but you can see the application icon color is more pure, true, this is a good change.   Fifth-generation multimedia 4K touch one ergonomic and aesthetic principles of design models, nice, very modern. Streamlined one-piece cabinet, simple and comfortable; high-quality cold-rolled steel material, the overall all-steel; all-metal surface paint process, completely moisture-proof, rust-proof, anti-acid, for a variety of different environments; cabinet containing a power control system, stereo sound system, external ATX host switching, high-performance axial fan, stable and reliable performance.   Biotechnology research and development personnel, the product according to the actual characteristics of ordinary primary and secondary schools, can completely replace the "Projector + computer + audio amplifier + + HD video booth electronic platform" and other traditional complex teaching mode, only one device can meet the multi-media teaching demand. Multimedia teaching environment is developed in a conventional audio-visual and computer equipment on the basis of both the teaching, research papers, conferences, comprehensive research, demonstration and exchange of distance learning, tele change volume, remote class, the topic and remote, remote conferencing, etc.    The series includes different models 55,65,70,84,98 inch, by video Technology fifth-generation multimedia 4K touch one touch function to meet the academic reports, meetings, academic exchanges, multimedia teaching, teaching and remote site education requires a comprehensive, intelligent management system and a good audio and video effects; better meet the comprehensive presentation, seminar through a variety of resources, slides, transparencies, multimedia courseware, video tapes, DVD / SVCD / VCD, and other physical data, live requirements, has a good effect of visual experience.
