Embodiment Construction

[0052] see now Figures 1 to 6 , a head-mounted display (HMD) according to a specific embodiment of the present invention will be described.

[0053] Any percentage of light given in this description should be understood to represent a fraction of the light energy relative to the total energy of the light in question.

[0054] Such an HMD 1 comprises an optical module 2 containing an image source 21, an imager 3 for directing light emitted by the image source 21 in operation to the wearer's eye E, and at least one optical module for filtering the light emitted by the image source 21 part of the filter. The filter may be placed anywhere in the optical path of light (from the image source) between the image source and the wearer's eye E.

[0055] The filter is specially conceived to ensure the image quality perceived by the wearer. Advantageously, the filter is conceived such that the same or as close as possible a level of image quality (virtually free of distortion) is obta...

Abstract

The invention provides a head-mounted display (1) comprising: - an optical module (2), which contains an image source (21); - an imager (3), which in operation The light emitted by the image source (21) is guided to the wearer's eye (E); and a filter for filtering a part of the light emitted by the image source (21). The invention also provides an ophthalmic lens (4) intended to be mounted on a head-mounted display (1) comprising an image source (21), wherein said ophthalmic lens (4) comprises a filter, the filter The light emitted by the image source (21) of the head mounted display (1) is intended to be filtered in operation.

Description

technical field [0001] The invention relates to the technical field of head-mounted displays. More specifically, the present invention relates to the technical field of head-mounted displays comprising an optical module containing an image source and an imager for directing, in operation, light emitted by the image source to the eyes of a wearer. Background technique [0002] A head-mounted display (HMD) is worn on the head so that one eye (monocular HMD– figure 1 ) or each eye (binocular HMD– figure 2 ) The display device that directly displays the information content in front of it. HMDs are also known as near-eye displays. [0003] HMDs can take various forms, including glasses, goggles, helmets, face shields, and goggles. [0004] In general, HMDs comprise an optical module with an image source, generally a microscreen, a laser diode, a light emitting diode type, an organic light emitting diode or a spatial light modulator, that generates a beam of light from an ele...
