How These Parameters Help Display Selection
PPI
PPI helps estimate image sharpness. Higher PPI is useful for close viewing distance, compact HMI panels, handheld devices, and round smart interfaces.
Pixel Pitch
Pixel pitch shows the physical distance between pixels. It is useful when evaluating readability, UI detail, and viewing distance.
Active Area
Active area helps mechanical engineers estimate the visible display width and height for enclosure design, lens design, and UI layout.
Aspect Ratio
Aspect ratio helps identify standard displays, wide displays, bar LCD modules, and stretched display formats for space-constrained products.
