- Der Blickwinkel bezeichnet die Perspektive, unter der bestimmte Dinge betrachtet werden bzw. die Sehrichtung, die sich von einem bestimmten Standpunkt aus ergibt. Der Begriff Blickwinkel (engl. viewing angle) wird im Deutschen in mehreren Bedeutungen verwendet:
* Eine umgangssprachliche Bezeichnung für die Sehrichtung auf ein visuelles Ziel
* Der Winkel zwischen einer Fläche und davon ausgehend ins Auge einfallenden Lichtstrahlen
* Die Auslenkung der Augäpfel beim Überschauen eines Blickfelds
* Im übertragenen Sinne: Betrachtung eines Themas von einem bestimmten Standpunkt aus (de)
- In display technology parlance, viewing angle is the angle at which a display can be viewed with acceptable visual performance. In a technical context, the angular range is called viewing cone defined by a multitude of viewing directions. The viewing angle can be an angular range over which the display view is acceptable, or it can be the angle of generally acceptable viewing, such as a twelve o'clock viewing angle for a display optimized or viewing from the top. The image may seem garbled, poorly saturated, of poor contrast, blurry, or too faint outside the stated viewing angle range, the exact mode of "failure" depends on the display type in question. For example, some projection screens reflect more light perpendicular to the screen and less light to the sides, making the screen appear much darker (and sometimes colors distorted) if the viewer is not in front of the screen. Many manufacturers of projection screens thus define the viewing angle as the angle at which the luminance of the image is exactly half of the maximum. With LCD screens, some manufacturers have opted to measure the contrast ratio, and report the viewing angle as the angle where the contrast ratio exceeds 5:1 or 10:1, giving minimally acceptable viewing conditions. The viewing angle is measured from one direction to the opposite, giving a maximum of 180° for a flat, one-sided screen. A display may exhibit different behaviour in horizontal and vertical axes, requiring users and manufacturers to specify maximum usable viewing angles in both directions. Usually the screens are designed to facilitate greater viewing angle in horizontal level, and smaller angle in the vertical level, should the two of them be different in magnitude. The viewing angle for some displays are specified in only a general direction, such as 6 o'clock or 12 o'clock. Early LCDs had strikingly narrow viewing cones, a situation that has been improved with current technology. Narrow viewing cones of some types of displays have also been used to bring a measure of security in businesses, where employees handle private information in the presence of customers, banks being one example. Rectangular filters fitting to the computer monitors have also been sold as accessories for this purpose. (en)
- 시야각(viewing angle)은 주로 디스플레이 장치에서 사용되는 용어로, 화면 정면에서의 광학특성에 비하여 휘도나 색도 감마 등이 특정 기준을 만족하는 좌우 또는 상하 방향의 최대 각도를 의미한다. 시야각이 좁으면 화면이 특정 각도에서 화질이 열화되는 단점이 있지만, 시야각이 넓으면 종이처럼 어는 각도에서든지 만족스러운 화질을 볼 수 있다. 이에 과학자들은 전자종이 등을 이용하여 시야각을 넓히려는 시도를 진행 중이다. (ko)
- De gezichtshoek is de ruimtelijke hoek waaronder beeldschermen en displays van apparaten zijn af te lezen. Fabrikanten spannen zich in om de gezichtshoek zo groot mogelijk te maken, zodat ook schuin van opzij het gegenereerde beeld goed zichtbaar is.Bij lcd-schermen is inversie een vervelend bijverschijnsel dat bestreden wordt. Onder bepaalde gezichtshoeken lijkt de zich qua kleuren 'om te draaien'. (nl)
