Abstract
Describe herein are electronic devices that includes a display stack having a cover component atop a lightguide component and a display component below the lightguide component. In some instances, the cover component including an antiglare layer having at least some antiglare properties applied to a top surface of a substrate and a touch pattern applied to a bottom surface of the substrate. In some cases, the touch pattern is a single layer multi-touch pattern connected to a touch controller to from a touch sensor capable of detecting the location of an object proximate to antiglare layer.
Claims20
An electronic device comprising;
- a display stack, the display stack including:
- a display unit to display content;
- a lightguide positioned above the display unit and configured to receive light from a light source, the light source being positioned at an edge of the lightguide;
- and
- a cover component positioned over the lightguide and the display unit, the cover component including:
- a transparent first substrate with a top surface and a bottom surface;
- an antiglare layer applied to the top surface of the transparent first substrate;
- a second substrate, with a top surface and a bottom surface, the top surface of the second substrate bonded directly to the bottom surface of the first substrate;
- and
- a multi-touch layer in contact with the bottom surface of the second substrate, the multi-touch layer including a first plurality of electrodes and a second plurality of electrodes located within a single layer.
A display stack for an electronic device, the display stack comprising:
- a cover component including:
- a first substrate having a top surface and a bottom surface;
- an antiglare layer disposed directly on the top surface of the substrate;
- a second substrate, having a top surface and a bottom surface;
- an index matching layer, having a top surface and a bottom surface, the bottom surface of the index matching layer in contact with the top surface of the second substrate;
- and
- a touch layer having a top surface and a bottom surface, the bottom surface of the touch layer in contact with the top surface of the index matching layer, the touch layer including a first plurality of electrodes and a second plurality of electrodes positioned within a single layer.
A method comprising:
- forming an antiglare layer directly over a top surface of a first substrate;
- forming an index matching layer directly on a bottom surface of the first substrate;
- forming a multi-touch pattern directly on a bottom surface of a second substrate, the multi-touch pattern having a first plurality of electrodes forming rows of the multi-touch pattern and a second plurality of electrodes forming columns of the multi-touch pattern within a single layer;
- and
- contacting a bottom surface of the index matching layer to a top surface of the second substrate.
