(A) screen size details
1. The screen measurement method and unit of measurement
Screen size of LCD Commercial Display measurement method is to measure the diagonal of the screen shall prevail, the unit of measurement is in inches as a unit of the imperial system. For example, we say that the screen size of 55 inches, that is, the diagonal of the screen is 55 inches (inches). 1 inch is equal to the metric system of 2.54 centimeters, then 55 inches of the screen diagonal length of 55X2.54 = 139.70 centimeters.
2. On the inch, inches, centimeters between the relationship and conversion
1 inch = 3.333333333333333 cm, and
1 inch = 1 inch = 2.54 centimeters
inch ≠ inch
Why is the 55-inch screen is often expressed as 55 inches, rigorously speaking, this expression is wrong. It may be the industry habit to express the inch as inch, so the magic art vision technology advertising machine screen size also take the industry agreed practice, with “inch” to express “inch”.
3. The relationship between the diagonal and length and width dimensions
Diagonal size is determined, but the aspect ratio is not determined, then the combination of length and width dimensions are also different. For example, the same 55-inch screen, 16:9 and 16:10 are not the same length and width, but all belong to the 55-inch screen. So when you come across a screen with the same diagonal length but different proportions, don’t be surprised to learn that “it” is also a screen of many, many inches. This “surprise” is often encountered in shaped screens, rectangular screens, and square screens.
When you know how wide you want the screen to be, you can make an initial guess as to what size screen you should use. For example, you want a screen width of 90CM, according to the Pythagorean theorem of right triangle relationship, the square of the length of the square + the square of the width of the square = the square of the diagonal, that is, a ² + b ² = c ², because now the screen are generally 16:9, so the length of 90CM, the height of the screen should be 50.62CM, a ² + b ² = c ² can be calculated as the diagonal of about 103CM, and then use 103 ÷ 2.54 = 40.65 inches, we know that you probably want to choose about 40 inches of screen.
