Scope
Scope: This document specifies the technical requirements and test methods for desktop long-distance electronic display devices. This document applies to electronic display devices that allow users to view images magnified and projected by an optical system through a window; Main technical content: Based on the principle of optical magnification, the image displayed on the screen of the source device at a predefined position within the desktop device is projected through an optical system to form an enlarged virtual image at a long viewing distance, solving the problem that flat-panel monitors cannot be viewed from a long distance when used directly on a desktop. It extends the viewing distance of desktop display devices from about 50 cm to more than 5 m.
