More than a decade ago, merchants would say that a 3-meter living room is most suitable for a 29-inch color TV, and now the merchants say that a 3-meter living room is most suitable for a 65-inch TV. Although this is a marketing method, in fact, with the iteration of technology, the previous TVs were 4:3 CRT picture tube TVs, if the screen is too large and the resolution cannot keep up, the picture is blurry.
For TVs, in theory, a TV with a larger screen size can bring a more powerful visual impact and immersion, but it does not mean that a TV with a larger screen size is more suitable for each user. If you're struggling with exactly how big a TV to buy at home, this article is definitely worth a look.
So how big is the TV to buy?
First, let's explore the problem of TV size. For the current family, from 40 square meters to 400 square meters of houses, the placement of the TV is not limited to the living room, based on most Chinese families for the comprehensive entertainment of the TV, placed in the living room will still be the first choice of most people, the width of the living room from 1.5 meters to the luxury villa at least 8 meters. Do we need to choose according to the width of the TV set from the human eye to see?
Due to the structure, the human eye can only see the range of about 150 degrees in front of the horizontal and about 140 degrees in length, so we watch TV as long as it is 40 degrees above and below, about 60 degrees of viewing angle, watching TV is clear, such a look and feel can already be. According to the current TV, LCD TV is 16:9 design, if the wide screen sits closer, it will definitely appear distorted in the left and right visual range, resulting in the viewing effect can not be optimized.
Although the current small size TV is becoming less and less, but there are still some small room users in use, in the 40-inch OR so TV, the appropriate viewing distance is about 1.0 meters, after all, the resolution of the small size TV can reach at least 1080P resolution, close can also see clearly.
There is a common misconception about large-sizeD televisions: the more tv is bigger, the more eye-hurting it is. In fact, blue light emissions, too close viewing distance, blurred picture quality are the real culprits of eye damage. Therefore, choosing a TV should not only look at the size, but also measure it in combination with the comprehensive performance of the TV.
Of course, no matter how large the size of the TV, there is a reasonable viewing distance, if the screen size is too large to watch the distance is too short, it is likely that due to insufficient visual space to cause the picture deformity and can not see all the pictures, may also cause damage to the human eye. Therefore, the choice of TV size is absolutely not to be sloppy.
In fact, for the SELECTION OF TV size, there is a set of calculation formulas:
Maximum TV size (inches) = viewing distance (cm) ÷3.736
Minimum TV size (inches) = viewing distance (cm) ÷6.227
Why it can be accurate to the last three decimal places, the following extrapolation process we can know why we can draw such a conclusion.
First, the size of the TV refers to the length of the diagonal of the TV screen, in inches (1 inch = 2.54 cm). And at present, the standard screen ratio of most LCD TVs has become 16:9 wide. According to the Pythagorean theorem , the length of the diagonal is √ 337 ( root number 337 ) open. The ratio of screen height to diagonal is 9÷√337.
Generally speaking, in the industry's view, the actual viewing distance is about 2 times the width of the screen. 3 times when the sense of presence is good, if it is less than this distance to see will be more tired, and 5 times the distance outside the viewing has no shocking power.
Set the minimum size is A (inch), the maximum size is B (inch), and the viewing distance is L (centimeters). Now we can build such an equation.
2.54A×(9÷√337)×5=L
2.54B×(9÷√337)×3=L
Available:
A=L÷6.226
B=L÷3.736
Therefore, taking the mainstream family living room sofa as an example of 3 meters away from the TV, it can be calculated that the size range of the TV is 48-85 inches. The distance calculated by this formula is the optimal distance between the human eye and the screen, and within this range is the most comfortable viewing distance for the human eye.
From the current overall sales of tv, 43, 55 and 65 inch TV is more popular, of which about 43 inches fit the bedroom, 55, 65 inches is currently the largest size segment, because its size can be well applied to the mainstream living room, so before buying a TV, you may wish to think about where to place the TV, and then see how large the size of the house is suitable for.
Finally, I also give you a small suggestion, we can choose a larger TV in the best size range when purchasing, because after actual use, I know that the TV is indeed the bigger it looks, the cooler it is.
