â– Flat viewing effect "small year-on-year"
According to Ernst & Young, in fact, compared to the same size flat-panel TV and CRT TV, the picture of the flat-panel TV seems to be smaller. For example, when a 34-inch CRT TV user upgrades to a flat-panel TV, he will take it for granted that he can buy a 37-inch LCD TV. In fact, under the same viewing distance, the viewing effect of the 37-inch LCD TV is only equivalent to a 25-inch ordinary CRT TV.
Han Qing, deputy general manager of TCL Thomson's China Business Center, also believes that the flat-panel TV has a higher definition. When viewing the CRT TV, the human eye can see a clear image farther than a flat-panel TV. In addition, when the human eye is watching a TV with a 4:3 format, it does feel that it is larger than a TV with the same aspect ratio of 16:9. Therefore, the CRT TV is simply upgraded in a 1:1 ratio. , did not achieve the expected results.
â– "Upgrade" 47-inch LCD is preferred
In response to this phenomenon, TCL proposed the principle of matching the viewing distance of the flat-panel TV with the screen size at the seminar. That is, the best-distance viewing angle of the same distance, the high-definition picture perception requires a 16:9 widescreen, large-sized flat-panel TV. Achieve the best display.
"This matching principle can provide a reference for consumers to purchase large-screen flat-panel TVs of various brands." Dai Qingsong, director of the China Product Design Institute of TTE Global R&D Center, said that consumers are watching TV at distances of 1.7 meters and 2.0 meters. At 2.4, 2.5, 2.7, 3.0, and 3.3 meters, 26-inch, 32-inch, 37-inch, 40-inch, 42-inch, 47-inch, and 52-inch LCD TVs maximize their high-definition Show the effect and give people an immersive experience.
According to the "2006 Second Quarterly Report on Consumer Demand Situation of Flat-panel TV Cities in China", the average living space of consumers who purchase flat-panel TVs at this stage averages 28m2 to 30m2. Dai Qingsong, director of the China Product Design Institute of TTE Global R&D Center, said that according to this data, the distance that residents should watch TV should be about 3 meters. Combined with the matching principle, it can be concluded that the 47-inch LCD TV will be more suitable for the use of households. When the original 34-inch CRT TV users are updated, the 47-inch LCD TV will be the best choice.
Optional tablet can not move CRT size
"It is a misunderstanding to purchase flat-panel TVs based on the size of traditional CRT TVs." At the seminar on the special research results of flat-panel TV size selection rules held recently, An Yongcheng, a senior engineer of the National Radio and TV Product Quality Supervision and Inspection Center, pointed out. When consumers buy large-screen flat-panel TVs, they often habitually use the traditional CRT color TV size as the reference standard, ignoring the difference in the screen size requirements of flat-panel TVs and traditional CRT TVs, so that when watching HDTVs Can't enjoy the best visual effects.
