Abstract

The disclosure provides a display of a head-mounted electronic device suitable for displaying image information to a user in a space formed by the head-mounted electronic device and a head of the user when the head-mounted electronic device is mounted on the user's head. The display includes a display panel and a light adjusting element. The display panel has a display region for displaying the image information. The light adjusting element is disposed on the display region to change a direction of light emitted from the display panel, so as to mitigate the screen-door effect and improve the displaying quality of the display.

First claim

What is claimed is:

1 . A display for a head-mounted electronic device, suitable for displaying image information to a user in a space formed by the head-mounted electronic device and the user's head, the display comprising:
a display panel, having a display region and configured to display the image information; and a light adjusting element, disposed on the display region, wherein the light adjusting element changes a direction of light emitted by the display panel to mitigate a screen-door effect.

2 . The display as claimed in claim 1 , wherein the light adjusting element comprises a diffuser disposed on the display region.

3 . The display as claimed in claim 2 , further comprising an adhesive layer located between the diffuser and the display region and covering the entire display region to adhere the diffuser to the display region.

4 . The display as claimed in claim 3 , wherein the adhesive layer is a semi-cured adhesive.

5 . The display as claimed in claim 2 , wherein the diffuser comprises a transparent substrate and a plurality of scattering particles distributed in the transparent substrate.

6 . The display as claimed in claim 1 , wherein the light adjusting element comprises a plurality of prism structures disposed on the display region.

7 . The display as claimed in claim 1 , wherein the display panel is a liquid crystal display panel or an organic light emitting diode display panel.

8 . A head-mounted electronic device, comprising:
a holder, suitable to be mounted to a user's head, so as to form a space with the user's head; a display, disposed on the holder and suitable to display image information to the user in the space, the display comprising:
a display panel, having a display region and configured to display the image information; and
a light adjusting element, disposed on the display region, wherein the light adjusting element changes a direction of light emitted by the display panel to mitigate a screen-door effect.

9 . The head-mounted electronic device as claimed in claim 8 , wherein the light adjusting element comprises a diffuser disposed on the display region.

10 . The head-mounted electronic device as claimed in claim 9 , wherein the display further comprises an adhesive layer located between the diffuser and the display region and covering the entire display region to adhere the diffuser to the display region.

11 . The head-mounted electronic device as claimed in claim 10 , wherein the adhesive layer is a semi-cured adhesive.

12 . The head-mounted electronic device as claimed in claim 9 , wherein the diffuser comprises a transparent substrate and a plurality of scattering particles distributed in the transparent substrate.

13 . The head-mounted electronic device as claimed in claim 9 , wherein the light adjusting element comprises a plurality of prism structures disposed on the display region.

14 . The head-mounted electronic device as claimed in claim 8 , wherein the display panel is a liquid crystal display panel or an organic light emitting diode display panel.
