60.3: Investigation on Viewing Angle Requirements and Glare with Respect to Size of Flat‐panel Television Displays

Abstract

This paper summarizes the results of an investigation on the viewing angle requirements for large flat-panel television displaysas well as on screen tilting as a means of reducing glare in accordance with the "Ergonomic Design Guidelines for Flat Panel Display Televisions" established by a special committee of the Japan Ergonomics Society. First, taking into account screen size, we investigated viewing angle requirements through a field survey of household television viewing conditions. We then evaluated the influence of the size, mounting height, and tilt of the screen on the occurrence of glare. Next, we conducted laboratory experiments to investigate the allowable tilt angle for ensuring acceptable viewing comfort and the optimum screen tilt angle for each mounting height. The results can be used as guidelines for adjusting viewing conditions as well as for ergonomic design of flat-panel television displays.

“…The dimensions involved were D2 (eye height) and D9 (eye height in sit position) in the 50 th percentile. The screen tilt angle was determined based on the viewing angle requirement for flat-panel display television [19]. Therefore, the tilt angle consideration was ranged from -8° to 8° and the information must be visible for sitting and standing person.…”

“…Although visual perception properties of AG coatings are not typically quanti-fied, quantitative metrics such as gloss, transmissive haze, and distinctness of image can be good indicators when evaluating and guiding the choice of AG solution for particular display applications. 9 The process choice for producing the AG coating will also be set by the intended application and substrate type. For example, in large-sized consumer displays where CG is not required, the simple lamination of plastic AG films from a wide range of inexpensive film solutions is sufficient.…”

“…Optimized processes can tune these microstructures to yield desired AG properties with only minimal increase to haze and the perception of sparkle. Although visual perception properties of AG coatings are not typically quantified, quantitative metrics such as gloss, transmissive haze, and distinctness of image can be good indicators when evaluating and guiding the choice of AG solution for particular display applications 9 . The process choice for producing the AG coating will also be set by the intended application and substrate type.…”

“…Unlike other application fields, viewing angle has been considered as an important image quality factor in TV application since multiple people can watch from various locations. In 2012, Igarashi et al showed survey results on where a large number of viewers are distributed around TVs in order to show how important the viewing angle is [1]. They investigated the real viewing location of 393 people from 83 households, and the results showed 95% of the subjects watched TV in a distribution within 45 degree.…”
