TV viewing distance Consumers can't spend a lot of time researching various technical parameters and metrics before buying a TV. Businesses and authoritative research institutions should give consumers the right guidance. As the world's largest color TV company, TCL has conducted extensive exchanges with industry experts on the basis of joint research results, and first proposed the matching principle of flat TV viewing distance and screen size (see below for matching table), which is selected by consumers. The purchase of large-screen flat-panel TVs provides a basis for reference.
The matching principle points out that the high-definition picture perception under the same distance and the best effective viewing angle requires a 16:9 widescreen, large-size flat-panel TV to achieve the best display. The distance to watch TV in residential households is at 1.7 m, 2.0 m, 2.4 m, 2.5 m, 2.7 m, 3.0 m, 3.3 m 26 inch, 32 inch, 37 inch, 40 inch, 42 inch, 47 inch, 52 inch
The LCD TVs can maximize their high-definition display and give them an immersive experience; at the above distances, 17-inch, 21-inch, 25-inch, 28-inch, 29-inch, 34-inch, The 43-inch CRT TV is enough to display the display it can achieve. Professor An Yongcheng from the Third Research Institute of the Ministry of Information Industry introduced that the design of the ordinary CRT is to display the current analog TV system. The clarity is only half of the definition of the high-definition TV. In addition, it uses 4: With the aspect ratio of 3, these factors ultimately lead to a very different choice between high definition LCD TVs and ordinary CRT TVs.
