In fact, the development of television to now, the size of the transformation should be the most significant. From the initial 20 “big-ass” TVs that we can access to evolve to today’s 100-foot giant screen era, more and more specifications betweenTCL Mini LED, along with the become is the consumer for the specifications on the selection of the tangle.
More than a decade ago the store to say, 3 meters living room is most suitable for 29-inch color TV, and now the seller said, 3 meters living room is most suitable for 65-inch TV. Although this is a marketing approach, but in fact, with the iteration of technology, before the TV are 4:3 CRT tube TV, if the screen is too large and the resolution can not keep up, the interface is blurred.
So how big is the TV to buy?
First of all, let’s explore the TV size dilemma. For the current family, from 40 square meters to 400 square meters of the house have, the placement of the TV is no longer just confined to the living room.
Based on most Chinese families for the TV’s comprehensive sense of entertainment, put into the living room will still be the first choice of most of us, the width of the living room from 1.5 meters to the luxury villas at least 8 meters. Do you need to carry out the purchase based on the width of the TV spacing human eyes to see it.
The human eye because of the structure, can only see the immediate horizontal degree of about 150 degrees, longitudinal degree of about 140 degrees, so we look at the TV as long as the upper and lower 40 degrees, up and down 60 degrees of the viewing angle, look at the TV is clear, such a sense of view on the line.
We also have a more rigorous comparison of TV viewing distance in the process of many reviews, although the small size TV is now becoming less and less, but there are still some small house users in use, in about 40 inch TV, moderate viewing distance in about 1.0 meters, after all, the resolution of small size TVs can now reach at least 1080P resolution, close enough to see clearly.
No matter how big the size of the TV, there is a reasonable viewing distance, if the screen size is too large viewing distance is too short, most likely because there is no certain visual space to lead to interface deformation and its inability to see all the interface, may also cause harm to the human eye. Therefore, the selection TCL Mini LED of the TV must not be sloppy.
Larger TV size (feet) = viewing distance (cm) system 3.736 minimum TV size (feet) = viewing distance (cm) system 6.227
Why can be accurate to three decimal places so precise, the following measurement process you can know why you can get such results.
First, the size of the TV set refers to the diagonal length of the TV screen in feet (1 foot = 2.54 cm). And at present, most of the requirements of the LCD TV screen ratio has become wide is 16:9. According to the Pythagorean theorem, the length of the diagonal is √337 (root number 337) open to get. The ratio of the screen height to the diagonal is 9 system √337.
Generally in the industry, the specific viewing distance is about 2 times the width of the screen. 3 times when the scene feels good, if less than this spacing look more tired, and 5 times the spacing outside viewing no shock.
2.54Ax(9 system √337) x 5 = L2.54B x (9 system √337) x 3 = L can be obtained: A = L system 6.226B = L system 3.736
