Abstract

This paper is concerned with the important visual variables that determine legibility of computer-controlled flat panel displays (FPDs). Thirty-five FPDs (29 LCDs, 3 PDPs, 2 ELDs, and 1 VFD) and five CRTs are analysed in relation to the following photometric properties: (1) Luminance and contrast ratio.(2) Specular reflectance.(3) Viewing angle dependency of contrast. Special equipments are developed and standardized conditions are applied to the measurements. For each visual variable the recommended level is determined on the basis of subjective evaluations and is compared with the presently used levels for that variable on several different displays. It can be concluded that manufacturers should pay more attention to human factors when designing displays.
