Along with digital TV Development Projector Product has grown from a simple Office Supplies To home entertainment products, more and more consumers begin to projection products as watching TV, movies tool. To correctly guide the consumer choose the right home projector products, China Electronic Standardization Institute Certification Center launched the "HD projector certification activities", the state of digital audio and video and multimedia product quality supervision and inspection center for specific testing.
Electronics industry standard SJ/T11340-2006 "LCD front projector universal norms", SJ/T11346-2006 "electronic projector measurement method" was officially released in 2006, the implementation of standards and how standards in this period to promote the healthy development of the projector industry has become the industry department in charge of the first problems to be solved. The key is the need to address this issue as a means, this means it is necessary to comply with international practice, but also as social recognition, begin voluntary certification to meet these requirements. First of all, the different characteristics of the product to carry out a voluntary certification is internationally accepted practice; Secondly, the projector of this consumer product choice and the interests of the consumers to carry out closely related to product performance certification, after all, a strategic choice. "HD projector certification activities" is the use of product certification system to regulate home projector market, leading manufacturer and implementing industry standards, and promote industrial technology, to protect the legitimate interests of consumers, promote the industry's healthy and harmonious development.
Clarity is the key to determine the performance
2005 2008 China projector market maintained fast development momentum, market sales and Sell Places have achieved rapid growth. Industry market, education and government procurement procurement projector sales are still the main market, accounting for the entire projector market share in most of sales. Although home projector sales in both sales and also very small, but the proportion of annual growth is largest, while the potential is greatest. It can be said with the continuous development of digital projection technology, the projector display technology products, performance indicators, applications and so have a significant expansion and upgrade, and its function is no longer just a single demonstration purposes only office, but increasingly more quickly into the home video, personal consumer goods.
With the popularity of home projectors, more and more clarity in this performance by the majority of consumer concerns, the projector features support for TV and for the family TV set to replace further deepened. Not only by the resolution of HD indicator index of, it and the interface function, image transformation processing, image filtering and enhancement techniques are inseparable, excellent results demonstrate the need for clarity with the results of various factors. Can be said that the merits of clarity index is a multi-projector integrated advanced image processing technology Cooperation Use, performance projector is the embodiment of comprehensive advantages.
Clarity and resolution has a very close relationship between the size of resolution directly affects the performance index definition, in the commercial market, mainly VGA640 480, SVGA800 600, XGA1024 768, WXGA1280 800, SXGA +1400 1050; in the home market, the mainstream for the 720P (1280 720,1280 768) and 1080P (1920 1080,1920 1200).
Obvious that the current products used in the projector resolution is very much, for domestic consumers, the need for a simple means to differentiate product performance, product definition projector just to meet the actual certification needs.
Market need to establish certification system
View of the current confusion in the market status of the projector, production enterprises, businesses on the product definition, brightness publicity unclear, inconsistent test basis, we need clarity for consumers are generally concerned about the performance of uniform evaluation But is the industry standard products SJ/T11340-2006 overall description of the whole performance, including image quality, sound quality, appearance technology, reliability, environmental adaptability, quality inspection rules, not suitable for clear and direct as the projector degree of performance certification standard.
