Abstract

One embodiment may take the form of a system for reducing the appearance of optical effects in a display. The system may include an enclosure with a first surface and a second surface. Furthermore, the system may include spacers that may be deposited on the bottom face of the first surface and/or the top face of the second surface, where the first surface may be a touch panel and/or cover lens and the second surface may be a display module. The spacers may be deposited in one layer with an anti-reflection coating. The thickness of the coating may be less than the diameter of the spacers.

First claim

What is claimed is:

1. A method for creating a display for an electronic device comprising:
depositing a coating onto a base layer of a bottom layer;
depositing a plurality of spacers onto the coating;
depositing an antireflection layer onto the coating, wherein the antireflection layer comprises a plurality of beads that are separate from the spacers;
connecting a top layer to the bottom layer to define a gap between the top layer and the bottom layer, wherein in response to a force on the top layer, the gap reduces from a maximum height to a minimum height, and wherein the minimum height is defined by the plurality of spacers.

2. The method of claim 1 , wherein the plurality of spacers are mixed within the coating.

3. The method of claim 2 , further comprising mixing the spacers into a curable material to create the coating.

4. The method of claim 3 , further comprising curing the curable material.

5. The method of claim 3 , wherein a thickness of the curable material is less than a diameter of the spacers.

6. The method of claim 1 , further comprising mixing the spacers with the antireflection layer.

7. The method of claim 6 , wherein depositing the plurality of spacers onto the coating comprises depositing the mixture of the spacers and the antireflection layer onto the coating.

8. The method of claim 7 , wherein the coating is a hard coating.

9. The method of claim 1 , wherein the spacers are hollow.

10. The method of claim 1 , wherein the spacers are translucent.

11. The method of claim 1 , wherein a diameter of the spacers is less than the maximum height.

12. The method of claim 1 , wherein the antireflection layer is interposed between the plurality of spacers and the coating.

13. The method of claim 1 , wherein the antireflection layer comprises the plurality of beads and the plurality of spacers such that the plurality of beads and the plurality of spacers are deposited in a single layer on the coating.

14. The method defined in claim 13 , wherein a diameter of at least one of the plurality of spacers is greater than a diameter of at least one of the plurality of beads.
