Software Simulates Sight: Flat Panel Mura Detection

About this technology

Overview

Radiant Imaging Inc., of Duvall, Washington, licensed the Spatial Standard Observer (SSO) software from Ames Research Center. The SSO simulates a simplified model of human spatial vision, operating on a pair of images that are viewed at a specific viewing distance with pixels having a known relation to luminance. The SSO software was used to develop the TrueMURA Analysis Module, incorporated into Radiant Imaging's ProMetric 9.1 system. When used in conjunction with the ProMetric Series Imaging Colorimeters, the new software module provides a complete characterization and testing system for flat panel displays, especially LCD panels and displays.
