Abstract

Une chambre de pressurisation (12) est agencée sur un côté inférieur d'un panneau de visualisation d'image agencé horizontalement (11). À l'intérieur de la chambre de pressurisation (12), il est possible d'effectuer une pressurisation avec de l'air en utilisant un ventilateur (15) et un orifice d'évacuation d'air (16) doté d'une section d'ajustement d'ouverture. Une force de gauchissement causée par la pesanteur est compensée par la force de l'air sous pression, et il est ainsi fait en sorte que le panneau de visualisation d'image (11) ne soit pas gauchi. Dans la mesure où l'air devant être utilisé pour la pressurisation est évacué à partir de l'orifice d'évacuation d'air (16), la chaleur générée à partir du panneau de visualisation d'image (11) peut également être dissipée avec l'air, et le panneau de visualisation d'image (11) peut être efficacement refroidi. D'autre part, dans la mesure où l'air est évacué vers le bas à partir de l'orifice d'évacuation d'air (16), il est fait en sorte que l'air ne soit pas directement dirigé vers un utilisateur qui visualise une image sur le côté du dispositif de visualisation d'image.
