Flexible display devices - Measuring methods of optical characteristics from the vantage point for curved displays1 Scope This part of IEC 62715, which is a technical specification, specifies the general rules and the details of optical measuring methods from a fixed point (the so called vantage point) for curved emissive and transmissive type displays such as OLED and LCD in dark room conditions. This document focuses on concave shape large screen displays (non portable) around a horizontal and or vertical axis with fixed or variable curvature radius. The
