Came 2005 Chinese projector market carried prosperous state 2008, market sales volume and sale all achieved rapid growth. Projector product is showing the respect such as domain of index of technology, function, application also had expand apparently with promotion, its function also has the onefold use that the office demonstrates only not just, however more and more apace enters domain of family expenses video and individual consumable field. The article with " measurement technique of SJ/T11346-2006 electron projector " for the basis, the projector product that shows field of technology, application to differring on the foundation of unified test method undertakes checking metrical be analyticed with data.
Evaluation system remains to perfect
Came 2005 Chinese projector market carried prosperous state 2008, market sales volume and sale all achieved rapid growth. In industry market, education is purchased and the government purchases the staple market that remains projector sale, held the most share of sales volume of whole projector market. Although domestic projector is very small still on sales volume and sale, but annual incremental ratio exemple is the biggest, at the same time latent capacity also is the biggest. On district, as western advance of a series of measure such as big development stage by stage, in China, western the sales volume of area of and other places also has rise significantly.
Can say to follow word of a move in chess or a movement in wushu the ceaseless development of umbriferous technology, projector product is showing the respect such as domain of index of technology, function, application all had expand apparently with promotion, its function also has the onefold use that the office demonstrates only merely no longer, and more and more apace enters domain of family expenses video, individual consumable field.
Distinguish from indication technology, projector basically can be divided at present for LCD(liquid crystal) , the digital light that DLP(is based on company of heart state apparatus to develop handles a technology) , LCOS(silicon base liquid crystal) 3 kinds big; Distinguish from function index, can divide for high-end machine (basically apply at project, cinema to wait) , in upright machine (basically apply at education, family to wait) , low end chance (basically apply at business affairs, conference to wait) 3 kinds big; From application the domain distinguishs, basically can divide wait for project, office, family expenses, business affairs. In recent years, weight of miniaturization projector product from 3 kilogram, 2 kilogram, 1.5 kilogram, 1 kilogram, reduce current 0.5 kilogram, miniaturization trend is clearer and clearer, and its application also expands from notebook computer palmtop computer, mobile phone, it is the play equipment such as PSP even.
In projector product application domain is refined ceaselessly abound ceaselessly with thorough, indication technology with perfect while, the product function index of projector also more and more get the attention of the user. " the projector before SJ/T11340-2006 liquid crystal is general technical condition " , " measurement technique of SJ/T11346-2006 electron projector " , " character of function of projector of JB/T5577-2002 transmission type determines method " , ISO21118, " SJ/T11298-2003 number projector is general technical condition " wait for a standard the function index to different projector product and test method undertook respectively. And the research analysis that already had a level domestic and internationally through be opposite, the evaluation method that unites at present and quality evaluation system still remain to perfect.
