"An important indicator of the projector light output, color performance, standby power consumption so low compliance rate, 3 percent false identification products in the phenomenon." Last weekend, China Electronic Chamber of Commerce and the China Electronics Standardization Institute jointly issued by China projector market research report.
China Electronic Chamber of Commerce, said the rapid development of China's projector market, but has long been the domestic market is not uniform, standardized criteria, leading to some projector manufacturers to greater profit margins, inflated virtual standard performance parameters, seriously disrupted the projector market.
April to June this year, China Electronic Chamber of Commerce reference to "electronic projector measurement" on the Chinese market, Epson, Sony, Lenovo and other 17 major brands, LCD, DLP, LCOS three types, 40 Mainstream projector products shall be selected for testing. 9 test targets, in addition to clarity, other indicators are problems: the key values of individual light output 50% lower than the standard brands; 70% of the standby power consumption of the product than the standard value of 5 watts; 55% The product should be greater than the threshold noise work; particularly serious is the test product performance in color generally not a satisfactory performance to achieve uniform illumination over 80% color gamut coverage of the product in 32% of all test products only 25%, there is a product illumination uniformity test value than the nominal value of 20 percentage points lower.
In addition, the product specifications You Sancheng false identity, is part of the projector manufacturer's product specifications nominal parameters incomplete. Manual is difficult to find some of the basic parameters of the nominal value of products, including machine power consumption, standby power consumption of the basic parameters of targets, including even light output, contrast. Wang Ning, vice chairman of China Electronic Chamber of Commerce, said, because even the most basic product specifications on the product parameter indicators are not, consumers to purchase these products only from the relevant digital, IT website to view the product specific parameters, but now Some related sites on the parameters of the nominal existence of a great "water", consumers simply were unable to identify whether there exists a standard product, which greatly increased the chances of consumers being taken.
"Did not expect such a serious phenomenon of Deficiency." SAIC Consumer Protection Bureau Director Li Zhencheng product sampling on the test results that surprised, he said, does not match the actual nominal and real is a fraud Business Administration Department in the future will focus on product sampling and sampling standard projector virtual phenomenon, those who refuse to be subject to administrative penalties.
According to reports, the current projector product measurement There are three standard reference: ANSI (American National Standards Institute standard), ISO (the Japanese office machine and Information System Industry Association performance of the projector based on determination of the international Projector standard) and "e-projector measurement methods" ("The People's Republic of China Electronic Industry Standard"). "E-projector measurement" is the Ministry of Information Industry in March 29, 2006 promulgated.
However, domestic market sales of projector products occupy over 90% of Japan's share of the brand, these products mainly refer to ISO measurement standards, reference to some other European and American standard ANSI measurement, different test methods will lead to differences in test results, final Product index mark will not unified.
The State Council Development Research Center of Market Economy Research Institute Director Lu Renbo believes it is the lack of a unified regulatory supervision, leading projector standard phenomenon of virtual product index popular, he thought the establishment of a unified, standardized industry standards is a priority. He said the last two years projector market by 40% market growth rate of rapid development, if standards can not keep up, market chaos will be difficult to change, will result in a weak position of consumers is more difficult to choose.
