The calculation of TFT display screen size is mainly based on the length of its diagonal, which is usually measured in inches. The following are detailed calculation methods and related explanations:

 1. Calculation of diagonal length

Definition: The size of a TFT display screen refers to the length of its diagonal, which is the straight-line distance from one corner to the other corner of its diagonal.

Unit: Inches are usually used as the unit, and 1 inch is equal to 2.54 centimeters (cm).

Example: For example, a 10.1-inch TFT display screen has a diagonal length of approximately 25.66 centimeters (10.1 inches x 2.54 centimeters/inch).

2. Application of Pythagorean theorem

Principle: Although diagonal length is a direct standard for defining the size of TFT displays, understanding the width and height of the display is also useful. These dimensions can be estimated using the Pythagorean theorem based on the diagonal length and aspect ratio of the display screen (such as 16:9).

Calculation: Assuming the aspect ratio of the display screen is 16:9, the width and height can be solved by setting equations (based on the Pythagorean theorem). However, since this calculation usually involves approximate values, it is best to directly consult the specification sheet provided by the manufacturer to obtain accurate width and height.

3. Precautions

Manufacturer specifications: The most accurate and reliable source of information is the specification sheet provided by TFT display manufacturers. These specification sheets will detail key parameters such as display screen size (diagonal length), resolution, aspect ratio, and physical dimensions (width and height).

Application scenario: When choosing the size of a TFT display screen, it is necessary to consider its application scenario. For example, portable devices such as smartphones and tablets typically use smaller display screens, while desktop computers, televisions, and game consoles may use larger display screens.

4. Common sizes

TFT display screens come in various sizes to meet the needs of different devices and application scenarios. Common sizes include 7 inches, 10.1 inches, 15.6 inches, 21.5 inches, etc. Each size of display screen has its specific purpose and advantages. For example, a 7-inch display screen is suitable for portable and mobile use, while a 21.5-inch display screen is suitable for professional applications that require high precision and clarity.

In summary, the calculation of TFT display screen size is mainly based on the length of its diagonal, and accurate size information can be obtained through the specification table provided by the manufacturer. When choosing a display screen size, it is necessary to consider comprehensively based on the application scenario and requirements.
