Outline dimensions are the overall physical size parameters of a display module (width, height and thickness). These dimensions refer to the full enclosure of the unit (including bezel, mounting frame, electronics, backlight, any protective glass or touch sensor), not just the active display area.
Knowing the outline dimensions is essential for designing the device’s enclosure, arranging components and planning how to mount the display (e.g. using VESA brackets or rails). Outline dimensions are usually specified in millimeters on a technical drawing (outline drawing), which serves as the primary reference for mechanical design in electronic and industrial products.
