Abstract
(EN) The present invention relates to a near-eye display apparatus comprising: a display; a first lens spaced a certain distance from the front surface of the display; a dynamic opening adjustment element which is adjacent to the first lens and dynamically controls the size of an opening of the first lens and the horizontal position and size of the opening on a plane perpendicular to the optical axis; a primary optical lens spaced a certain distance from the first lens; and a control unit for controlling the dynamic opening adjustment element. The pupil of an eyeball of an observer is positioned at an exit pupil spaced a certain distance from the primary optical lens, and the size and horizontal position of the exit pupil are adjusted according to the size and horizontal position of the opening of the dynamic opening adjustment element which are adjusted according to a control signal of the control unit.
(FR) La présente invention concerne un appareil d'affichage proche de l'œil comprenant : un affichage ; une première lentille espacée d'une certaine distance de la surface avant de l'affichage ; un élément d'ajustement d'ouverture dynamique qui est adjacent à la première lentille et commande de manière dynamique la taille d'une ouverture de la première lentille et la position horizontale et la taille de l'ouverture sur un plan perpendiculaire à l'axe optique ; une lentille optique primaire espacée d'une certaine distance de la première lentille ; et une unité de commande permettant de commander l'élément d'ajustement d'ouverture dynamique. La pupille d'un globe oculaire d'un observateur est positionnée au niveau d'une pupille de sortie espacée d'une certaine distance de la lentille optique primaire, et la taille et la position horizontale de la pupille de sortie sont ajustées selon la taille et la position horizontale de l'ouverture de l'élément d'ajustement d'ouverture dynamique qui sont ajustées selon un signal de commande de l'unité de commande.
