Embodiment Construction

[0037] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be practiced in various ways and is not limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0038] As previously mentioned, the eye can exhibit various aberrations such as defocus, astigmatism, curvature of field, spherical aberration, and / or coma. In the following, for simplicity, only myopia is used as an example for description. However, it will be apparent to those skilled in the art that the principles of the present disclosure can be applied to any aberration.

[0039] as before figure 1 As mentioned above, since the conventional...

Abstract

The invention relates to a display device. The display device comprises a display and a spatial light modulator. The display comprises a plurality of display pixels. The light strength of each display pixel is adjustable, so that a first image is displayed on the display. Light emitted by the display is emitted through the spatial light modulator and enters an eye, and predetermined transmissivity distribution or reflectivity distribution is formed on the spatial light modulator, wherein the first image and the transmissivity distribution or the reflectivity distribution are set so as to enable imaging of light emitted from the spatial light modulator at the retina of the eye to have a predetermined field curvature, so that the imaging points on the peripheral part outside the visual axis of the eye are basically arranged on the retina of the eye. The display device provided by the invention is capable of delaying the image difference progress of the eye of the user.

Description

technical field [0001] The present disclosure relates to a display device, and more particularly, to a display device capable of slowing down the progression of an aberration of a user's eye. Background technique [0002] In general, the eye may have various aberrations such as defocus, astigmatism, curvature of field, spherical aberration, and / or coma. [0003] Currently, since most people have to use display devices for a long time for work and study, eye fatigue symptoms are very common. In addition, the recently-appeared head-mounted display devices are also prone to visual fatigue symptoms. [0004] On the other hand, aberrations of the eye are progressive. Taking defocus as an example, the rate of progression of myopia is increasing day by day. [0005] For nearsightedness, the quality of vision is usually improved by moving the imaging point from in front of the retina to onto the retina with spectacles or contact lenses. However, because the user often needs to f...
