Abstract
An electronic device is provided. The device comprises a display module comprising an active area configured to emit light, and a window layer attached to the display module. The window layer comprises: a transparent area positioned above at least the active area of the display module, an area extending outwards relative to the active area of the display module, and an optical pattern configured to direct the light emitted by the active area of the display module near the edges of the active area towards the area of the window layer extending outwards.
Claims20
A device, comprising:
- a display module comprising an active area configured to emit light,
- a window layer attached to the display module, wherein the window layer comprises:
- a transparent area positioned above at least the active area of the display module,
- an area extending outwards relative to the active area of the display module, and
- an optical pattern configured below a surface of the window layer, the optical pattern comprising a plurality of light steering elements positioned in a material of the window layer at a distance from the surface of the window layer and extending from outside of edges of the active area and only within an inactive area to direct the light emitted by the active area of the display module near the edges of the active area towards the area of the window layer extending outwards.
A device, comprising:
- a display module comprising an active area configured to reflect light,
- a window layer attached to the display module, wherein the window layer comprises:
- a transparent area positioned above at least the active area of the display module,
- an area extending outwards relative to the active area of the display module, and
- an optical pattern configured below a surface of the window layer, the optical pattern comprising a plurality of light steering elements positioned in a material of the window layer at a distance from the surface of the window layer and extending from outside of edges of the active area and only within an inactive area to direct the light reflected by the active area of the display module near the edges of the active area towards the area of the window layer extending outwards.
A method of manufacturing a device with a display, the method comprising:
- assembling a display module comprising an active area configured to emit or reflect light;
- attaching a window layer with optically clear adhesives to the top of the display element, wherein the window layer is positioned such that the window layer covers the active area of the display module, and an area of the window layer extends outwards relative to the active area of the display module;
- and
- producing an optical pattern below a surface of the window layer in the area of the window layer extending outwards by treating a material of the window layer, the optical pattern comprising a plurality of light steering elements positioned in the material of the window layer at a distance from the surface of the window layer and extending from outside of edges of the active area and only within an inactive area, wherein the optical pattern is configured to direct the light emitted or reflected by the active area of the display module near the edges of the active area towards the area of the window layer extending outwards.
