1. The viewing distance and the size of the TV
The larger the screen of the TV, the greater the viewing distance required, which should be because the human eyes are not moving Under the circumstances, the viewing angle is limited, and a reasonable distance is required to allow people to see every corner of the TV screen clearly without turning their eyes and head. The general recommended viewing distance is 3-4 times the height of the TV.
Second, the viewing distance and the point distance of the TV
The point distance refers to the distance between the pixels of the TV screen, which is proportional to the screen size. Inversely proportional to the screen resolution, a screen with a high resolution and a low dot pitch has a better performance for the details of the picture. If the viewing distance is too close, and the point distance is too large, the screen will be obviously gridded, and the flicker will seriously affect the screen effect. Therefore, TVs that want to watch at close range should not only use small-screen TVs, but also pay attention to choosing models with the smallest dot pitch. In this aspect, LCD TVs have obvious advantages.
Three, the viewing distance and the brightness of the TV
The brightness parameters of the TV are very different, ranging from 300-1000nit. Two degrees higher will produce a dazzling feeling and even burn the eyes. The eyes with too low brightness must be highly concentrated, which is very easy to fatigue. Long-term use of low-brightness products is more prone to myopia. The light intensity in the transmission will weaken with the distance. Generally, the energy of the TV is mainly spread in the range of 160 degrees up, down, left and right. The theory requires that the light intensity transmitted to the human eye is preferably between 85-110nit, which is to ensure visual health. an ideal value of . Usually the viewing distance for reference is about one hundredth of the brightness of the TV screen.
Fourth, how to calculate the proportional relationship between TV screen size and viewing distance?
Maximum TV size (inches) = viewing distance (cm) ÷ 3.736
Minimum TV size (inches) = viewing distance (cm) ÷ 6.227
First of all, what we need to know is that TV size refers to the length of the diagonal of the TV screen, in inches, 1 inch = 2.54 cm. Moreover, the standard screen ratio of digital TV is 16:9. According to the Pythagorean theorem, the length of the diagonal is √337 (square root 337). The ratio of screen height to diagonal is 9÷√337.
Next, is the key to our problem-solving. Generally speaking in the industry, the actual viewing distance is 3-5 times the height of the screen. At 3 times, the sense of presence is good. If it is less than this distance, it will be more tiring to watch, and it will not be shocking to watch at a distance of 5 times.
Let the minimum size be A (inches), the maximum size be B (inches), and the viewing distance be L (centimeters). Now, we can build such an equation.
2.54A×(9÷√337)×5=L
2.54B×(9÷√337)×3=L
Obtain:
A=L÷6.226
B=L÷3.736
For example, if the viewing distance is 3 meters, the size range of the TV is 48-80 inches . I believe that everyone has a general understanding of the choice of TV size. Let’s calculate what size TV is suitable for your room.
5. Bedroom TV cabinet height selection
The healthy height of the bedroom TV cabinet depends on the height of the bed and this calculation can be used Method. However, the height of the TV cabinet in the bedroom is relatively higher than that in the living room, because this needs to be symmetrical with the height of the bed. Generally, the height of the TV cabinet in the bedroom is about 45cm to 55cm.
The height of the TV cabinet in the bedroom needs to be determined according to the specific situation. In fact, everything in the bedroom needs to be considered in combination with many things, such as the color matching of the bedroom, whether the overall style of the bedroom matches with others, and so on.
Six, what is the appropriate size of the TV cabinet in the bedroom
Space size
To talk about the selection of the size of the TV cabinet, it is very important to the overall space There are many requirements for the size, and the size of the TV cabinet needs to be considered according to the size of the space. The size of the more common TV cabinet is about 2400*500*460mm. If the space is relatively large, the TV cabinet can be larger. If the space is relatively small, the size of the TV cabinet can be smaller, and it can be matched with the whole space to avoid abruptness.
TV size
Consider the size of the TV cabinet, and the size of the TV is also the main consideration. According to the needs of modern users for home use, the size requirements for TVs are also different. Now, 55 inches, 65 inches, etc. are more common. Considering the size of the TV cabinet, it must be matched with the TV to ensure stable use.
