Method of embedding an imaging device within a display
A display unit including a liquid crystal layer, a plurality of optical layers and an imaging device. The imaging device is aligned to a portion of the display unit, the portion configured to transmit more than 10% of light rays to the imaging device. A method of assembling the same is also provided.
1. A display unit comprising:
a liquid crystal layer including a portion comprising an optically transparent substance injected into the liquid crystal layer;
a plurality of optical layers; and
an imaging device, wherein the imaging device is at least partially embedded within the plurality of optical layers and aligned to the portion, the portion being configured to transmit more than 10% of light rays to the imaging device, and wherein the portion does not extend through the plurality of optical layers and the optically transparent substance is different from a material of the liquid crystal layer.
2. The display unit of claim 1 , wherein the optically transparent substance is configured to transmit light rays within a visible and infrared regions.
3. The display unit of claim 1 , wherein the light rays transmitted have a wavelength within an infrared region.
4. The display unit of claim 1 , wherein the imaging device is arranged within any layer of the display unit or external of any layer of the display unit.
5. The display unit claim 1 , wherein the imaging device is arranged within the plurality of optical layers.
6. The display unit of claim 1 , wherein the plurality of optical layers is arranged between the liquid crystal layer and the imaging device.
7. The display unit of claim 1 , wherein the imaging device is arranged at least partially within the portion.
8. The display unit of claim 1 , wherein the portion is part of the liquid crystal layer.
9. The display unit of claim 1 , wherein the portion defines a field of view (“FOV”) of the imaging device to observe an ambient environment.
10. The display unit of claim 1 , wherein the portion defines a field of view (“FOV”) of the imaging device to observe a vehicle cabin.
11. A method of assembling a display unit, the method comprising:
providing a liquid crystal layer and a plurality of optical layers;
providing a portion within the liquid crystal layer, wherein the portion does not extend through the plurality of optical layers;
aligning an imaging device to the portion; and
configuring the portion to transmit more than 10% of light rays to the imaging device by injecting an optically transparent substance different from a material of the liquid crystal layer into the liquid crystal layer such that more than 10% of light rays passes through the optically transparent substance.
12. The method of claim 11 , wherein the optically transparent substance is configured to transmit light rays within a visible and infrared regions.
13. The method of claim 11 , wherein the optically transparent substance is configured to transmit light rays within an infrared region.
14. The method of claim 11 , further comprising placing a plurality of spacers within the liquid crystal layer, for partitioning the optically transparent substance from the liquid crystal layer.
15. The method of claim 11 , wherein configuring the portion further comprises providing a cavity in the plurality of optical layers such that more than 10% of light rays passes through the cavity and the optically transparent substance.
16. The method of claim 11 , wherein configuring the portion further comprises arranging the imaging device and the optically transparent substance entirely within the portion such that more than 10% of light rays passes through the optically transparent substance.
