Extended data:
The bigger the TV screen, the greater the distance you need to see, which should be limited and reasonable for the human eye without rotating. Because of the demand, people can see every corner of TV images clearly with their eyes and heads that can no longer move. It is generally recommended that the viewing distance is 3-4 times the height of the TV.
The brightness parameters of TV vary greatly, ranging from 300 to 1000 nits. Above 2 degrees Celsius, it will produce a dazzling feeling and even burn your eyes. Eyes with low brightness must be highly focused and prone to fatigue. Long-term use of low-brightness products is more likely to suffer from myopia. The light intensity in the transmission process will decrease with the increase of distance.
Generally, the energy of TV mainly propagates in the upper and lower range of 160 degrees. Theoretically, the light intensity transmitted to human eyes is required to be between 85- 1 10NIT, which is an ideal value to ensure visual health. Usually the reference viewing distance is about 1% of the brightness of the TV screen.
