Abstract

A wearable electronic display that includes an eyewear frame having a first side frame portion. A display module with a micro-display for generating images can be mounted to the first side frame portion. The display module can have an elongate portion with an image exit window positioned for directing viewable images to a user's eye.

First claim

What is claimed is:

1. A wearable electronic display comprising:
an eyewear frame having a front frame portion connected to a first side frame portion;
a display module mounted to the eyewear frame within an interior corner between the front frame portion and the first side frame portion, having a micro-display for generating images, the display module having an elongate portion with an image exit window positioned for directing viewable images to a user's eye; and
an adjustment mechanism extending within the interior corner for adjusting the position of the image exit window, the adjustment mechanism adjustably mounting the display module to the eyewear frame, and providing rotational adjustment about a lateral axis and linear adjustment along the lateral axis of the display module within the interior corner, the lateral axis extending laterally relative to the first side frame portion into the interior corner spaced apart from and adjacent to an interior side of the front frame portion, the adjustment mechanism comprising an adjustment bracket movably mounting the display module to the eyewear frame, the adjustment bracket is rotationally mounted to the eyewear frame about the lateral axis by a rotational mechanism having a lateral pivot on the lateral axis, and the display module is slidably mounted with the adjustment bracket along the lateral axis by a sliding mechanism, the rotational mechanism includes an adjustment gear mounted to the adjustment bracket in a rotationally fixed manner about the lateral axis, rotationally engaging a rotatable geared rotational adjustment actuator, the sliding mechanism includes a series of protrusions extending from the display module and slidably engaging linear guide tracks within the adjustment bracket, a rotatable linear adjustment actuator rotatably mounted to the adjustment bracket has a cam surface for movably engaging at least one of the protrusions for slidably moving the display module back and forth relative to the adjustment bracket along the lateral axis, the linear adjustment actuator includes an elongate slot forming the cam surface.

2. The wearable electronic display of claim 1 in which the eyewear frame has a second side frame portion, and the front frame portion is connected between the first and second side frame portions, the front frame portion having at least one of above eye and below eye frame members.

3. The wearable electronic display of claim 1 in which the front frame portion having at least one above eye frame member, the elongate portion of the display module laterally extends generally along the level of the at least one above eye frame member, and the image exit window is tilted in a downwardly direction for viewing.

4. The wearable electronic display of claim 1 in which the eyewear frame has the configuration of eyeglasses, with the front frame portion having above eye and below eye frame members being upper and lower portions of two eyewear rims, respectively, and the elongate portion of the display module having a similar width and/or thickness as the eyewear rims, while extending laterally generally along the level of the above eye frame members of the eyewear rims with the image exit window being positioned near or at the center of an eyewear rim.

5. The wearable electronic display of claim 1 in which the display module has an angular shaped portion that at least a portion thereof is positioned in the interior corner.

6. The wearable display of claim 1 in which the elongate slot is at least one of a linear and a spiral slot.

7. A method of viewing images comprising:
wearing a wearable electronic display, the wearable electronic display having an eyewear frame with a front frame portion connected to a first side frame portion worn by a user, a display module being mounted to the eyewear frame within an interior corner between the front frame portion and the first side frame portion and having a micro-display for generating images;
directing viewable images to an eye of the user from an image exit window positioned at an elongate portion of the display module; and
adjusting the position of the image exit window with an adjustment mechanism extending within the interior corner, the adjustment mechanism adjustably mounting the display module to the eyewear frame, and providing rotational adjustment about a lateral axis and linear adjustment along the lateral axis of the display module within the interior corner, the lateral axis extending laterally relative to the first side frame portion into the interior corner spaced apart from and adjacent to an interior side of the front frame portion, the adjustment mechanism comprising an adjustment bracket movably mounting the display module to the eyewear frame, the adjustment bracket is rotationally mounted to the eyewear frame about the lateral axis by a rotational mechanism having a lateral pivot on the lateral axis, and the display module is slidably mounted with the adjustment bracket along the lateral axis by a sliding mechanism, the rotational mechanism includes an adjustment gear mounted to the adjustment bracket in a rotationally fixed manner about the lateral axis, rotationally engaging a rotatable geared rotational adjustment actuator, the sliding mechanism includes a series of protrusions extending from the display module and slidably engaging linear guide tracks within the adjustment bracket, a rotatable linear adjustment actuator rotatably mounted to the adjustment bracket has a cam surface for movably engaging at least one of the protrusions for slidably moving the display module back and forth relative to the adjustment bracket along the lateral axis, the linear adjustment actuator includes an elongate slot forming the cam surface.

8. The method of claim 7 further comprising providing the eyewear frame with a second side frame portion, and the front frame portion is connected between the first and second side frame portions, the front frame portion having at least one of above eye and below eye frame members.

9. The method of claim 7 further comprising:
providing the front frame portion with at least one above eye frame member;
laterally extending the elongate portion of the display module generally along the level of the at least one above eye frame member; and
tilting the image exit window in one of upwardly or downwardly directions for viewing by the eye of the user.

10. The method of claim 7 further comprising:
providing the eyewear frame with the configuration of eyeglasses, and the front frame portion having above eye and below eye frame members being upper and lower portions of two eyewear rims, respectively; and
providing the elongate portion of the display module with a similar width and/or thickness as the eyewear rims, and extending the elongate portion of the display module laterally generally along the level of the above eye frame members of the eyewear rims with the image exit window being positioned near or at the center of an eyewear rim.

11. The method of claim 7 further comprising providing the display module with an angular shaped portion, and positioning at least a portion thereof in the interior corner.

12. The method of claim 7 further comprising forming the elongate slot as at least one of a linear and spiral slot.

13. A wearable electronic display comprising:
an eyewear frame having a first side frame portion;
a display module mounted to the eyewear frame having a micro-display for generating images, the display module having an elongate portion with an image exit window positioned for directing viewable images to a user's eye; and
an adjustment mechanism for adjusting the position of the image e
