Electronic device with a display attached to a lens element
A head-mounted device may have a display that displays content for a user. Head-mounted support structures in the device support the display on the head of the user. The head-mounted device may have a left lens that directs images from the left portion of the display to a left eye box and a right lens that directs images from the right portion of the display to a right eye box. Each lens may include a lens element that is coupled to the display. The lens element may be attached to the display with a layer of optically clear adhesive or the lens element may be formed from gel that directly contacts the display. The lens element attached to the display may have protrusions or recesses to accommodate input-output components. A single lens element may be attached to both the left and right portions of the display.
1. A system, comprising:
a head-mounted support structure;
a display having a display surface;
a lens element supported by the head-mounted support structure, wherein the lens element has a surface that faces and receives light from the display surface and wherein the surface of the lens element is optically and physically coupled to the display surface; and
an additional lens element aligned with and coupled to the lens element, wherein the additional lens element is a rigid lens element and is separated from the display surface by a gap and wherein the lens element fills the gap, wherein the lens element comprises a first material that has a first refractive index, wherein the additional lens element comprises a second material that has a second refractive index that is higher than the first refractive index, wherein the lens element has an additional surface that is interposed between the additional lens element and the surface of the lens element, and wherein the additional surface of the lens element provides refractive power to the system.
2. A system, comprising:
a head-mounted support structure;
a display having a display surface; and
a lens element supported by the head-mounted support structure, wherein the lens element has a surface that faces and receives light from the display surface, wherein the surface of the lens element is optically and physically coupled to the display surface, wherein the surface of the lens element is a first surface, wherein the lens element has a second surface that opposes the first surface and an edge between the first and second surfaces, wherein the lens element has a protrusion that extends from the edge, and wherein the system further comprises an input-output component mounted to the protrusion.
3. A system, comprising:
a head-mounted support structure;
a display having a display surface; and
a lens element supported by the head-mounted support structure, wherein the lens element has a surface that faces and receives light from the display surface, wherein the surface of the lens element is optically and physically coupled to the display surface, wherein the surface of the lens element is a first surface, wherein the lens element has a second surface that opposes the first surface and an edge between the first and second surfaces, wherein the lens element has a recess in the edge, and wherein the system further comprises an input-output component mounted in the recess.
4. A system, comprising:
a head-mounted support structure;
a display having a display surface;
a lens element supported by the head-mounted support structure, wherein the lens element has a surface that faces and receives light from the display surface, wherein the surface of the lens element is optically and physically coupled to the display surface, and wherein the head-mounted support structure comprises a lens module support structure that supports the lens element; and
a camera that is aligned with an opening in the lens module support structure, wherein the camera captures images through the opening and the lens element.
5. The system defined in claim 4 , further comprising:
a camera lens element aligned with the opening and mounted on an edge of the lens element.
6. A system, comprising:
a head-mounted support structure;
a display having left and right display portions configured to display an image;
a first lens element that is coupled to both the left and right display portions, wherein the first lens element spans a gap between the left and right display portions, wherein the first lens element has a left portion that directs a portion of the image from the left display portion to a left eye box, wherein the first lens element has a right portion that directs a portion of the image from the right display portion to a right eye box, wherein the first lens element has first and second opposing surfaces, and wherein the first surface of the first lens element is coupled to the left and right display portions;
a second lens element that is attached to the second surface of the first lens element, wherein the second lens element is attached to the left portion of the first lens element; and
a third lens element that is attached to the second surface of the first lens element, wherein the third lens element is attached to the right portion of the first lens element.
7. The system defined in claim 6 , further comprising:
a first layer of optically clear adhesive that overlaps the left display portion and couples the left display portion to the first lens element; and
a second layer of optically clear adhesive that overlaps the right display portion and couples the right display portion to the first lens element.
