Abstract

A near-eye display device includes a display panel and a plurality of light modulation units. The display panel includes a plurality of display pixel units configured to emit display light. The light modulation units are disposed on a light emitting surface of the display panel, and each of the light modulation units is disposed corresponding to one of the display pixel units. Each of the light modulation units is configured to direct the display light emitted from the corresponding display pixel unit to an eye of a user, and a width of the display light directed to the eye of the user is smaller than the pupil size of the eye. The user may still receive clear images when the near-eye display is out of focus because the display light directed to the eye has the width smaller than the pupil size.

Claims7

Dependent claims

A near-eye display device, comprising:

a display panel comprising a plurality of display pixel units configured to emit display light;
and
a plurality of light modulation units disposed on a light emitting surface of the display panel, wherein each of the light modulation units is disposed corresponding to one of the display pixel units, each of the light modulation units is configured to direct the display light emitted from the corresponding display pixel unit to an eye of a user, and a width of the display light directed to the eye of the user is smaller than the pupil size of the eye, wherein each of the light modulation units comprises:
a microlens;
and
a light shielding layer having a pinhole disposed between the light emitting surface of the display panel and the microlens, wherein each of the microlenses is disposed corresponding to only one of the display pixel units and only one of the pinholes, and each of the pin holes is smaller than the corresponding microlens.
