IEC 62906-5-1:2021（E）规定了使用激光或激光混合光源的无屏幕前投影显示器的标准测量条件和测量方法。混合光源可以使用激光器和基于自发辐射的光源。本文件涵盖了全帧投影技术的光学性能测量，如数字微镜器件（DMD）、硅上液晶（LCOS）和液晶显示（LCD）投影仪。不包括光栅扫描（飞点）投影显示器等其他显示器。

IEC 62906-5-1:2021(E) specifies the standard measurement conditions and measurement methods for front projection displays without screen which use lasers or laser hybrids as light sources. The hybrid light sources can use both lasers and spontaneous emission-based light sources. This document covers optical performance measurements for full-frame projection technologies such as digital micro mirror devices (DMDs), liquid crystal on silicon (LCOS), and liquid crystal display (LCD) projectors. Other displays, such as raster-scanned (flying spot) projection displays, are not included.
