In CAD drawings of segmented screen specifications, we often see the following viewing angles: 6 o'clock, 12 o'clock, 9 o'clock, and 3 o'clock. We're confused about what these parameters represent, and how should we effectively apply them during development?
The viewing angle refers to the maximum deviation from the normal to the front of the screen at which characters or symbols can still be clearly discerned. In other words, the image is clearest when viewed directly from the normal to the front. As the screen deviates from the normal, the image becomes increasingly blurry.
A 6 o'clock angle is typically considered an upward viewing angle, suitable for low-mounted installations, while a 12 o'clock angle is considered a downward viewing angle, suitable for high-mounted installations (such as wall-mounted control panels). A 12 o'clock angle is considered a downward viewing angle, suitable for viewing from above (such as desktop instruments or handheld devices).
This directly impacts the product's application. If you're still unsure about your selection, please contact us and our professional engineers will provide you with sound advice and design advice.
