First, the status quo of flat-panel TV size selection
The survey results show that when consumers purchase large-screen flat-screen TVs, they often habitually use the traditional CRT color TV size as a reference standard, ignoring the differences in the screen size requirements of flat-panel TVs and traditional CRT TV display performance. Experts pointed out that buying flat-panel TVs based on traditional CRT TV size is a kind of consumer misunderstanding.
At the conference, TCL took the lead in putting forward the principle of matching flat-panel TVs on the basis of research results. Under the same distance, high-definition LCD TVs need larger sizes to achieve the best viewing results.
There are misunderstandings in the use of CRT size selection experience for flat-panel TVs. In the quarterly survey of Chinese flat-panel TV consumer markets, special investigations were conducted on flat-panel TV users and potential consumer purchase behaviors and usage characteristics. The survey involved nearly 12,000 samples of large and medium-sized cities with 30 flat-panel TVs in the country. 
The survey results show that when consumers purchase flat-screen TVs, they often use the experience of selecting the CRT TV size for simple extension and analogy. For example, when a 34-inch CRT TV user upgrades to a flat-panel TV, he or she will take it for granted that a 37-inch LCD TV can be purchased, but the actual use results are less than expected.
Second, flat TV size matching principle
The matching principle points out that the high-definition picture look and feel at the best effective viewing angle requires a 16:9 widescreen, large-size flat-panel television to achieve the best display effect.
TV distances in residential homes are 1.7 meters, 2.0 meters, 2.4 meters, 2.5 meters, 2.7 meters, 3.0 meters, 3.3 meters, 26 inches, 32 inches, 37 inches, 40 inches, 42 inches, 47 inches, 52 inches The LCD TVs can maximize their high-definition display and give people immersive experience. The 17-inch, 21-inch, 25-inch, 28-inch, 29-inch, 34-inch, and 43-inch CRT televisions at the above distance are sufficient to display the display effect they can achieve. 
According to Professor An Yongcheng, the third institute of the Ministry of Information Industry, the design of ordinary CRTs is designed to show the current analog television system, and its definition is only half as high as that of high-definition televisions. In addition, it uses 4: The aspect ratio of 3, these factors finally led to high-resolution LCD TVs and ordinary CRT TV selection criteria are very different.
According to data from the 2006 Second Quarter Report of China's Flat-panel TV City Consumer Demand Research, the average living space for potential buyers of flat-panel TVs is 28m2 to 30m2 at this stage.
Dai Qingsong, director of the China Product Design Institute of TTE Global Research and Development Center, expressed that according to this data, the distance of households watching TV should be about 3 meters. According to the principle of matching, 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 user was updated, the 47-inch LCD TV would be the best choice.
