螢幕h w d意思

"H", "W", and "D" in the context of a screen or display typically stand for "Height", "Width", and "Depth" or "Diagonal". These terms are used to describe the dimensions of the screen.

• Height (H): This refers to the vertical length of the screen, from the top to the bottom.
• Width (W): This refers to the horizontal length of the screen, from left to right.
• Depth (D): This could refer to two different things depending on the context:
  • If the context is about the physical dimensions of the screen, "depth" refers to the thickness of the screen.
  • If the context is about the screen size, "diagonal" (which is represented by the letter "D" in some cases) refers to the length of the diagonal of the screen from one corner to the opposite corner. This is the most common way to specify the size of a screen, such as a television or a computer monitor.

For example, a screen with a size of 24 inches might be described as "24-inch Diagonal (D)", "24-inch Width (W)", or "24-inch Height (H)" depending on the specific information being provided. If the depth is provided, it would give you the thickness of the screen.
