Methods and apparatus to construct an ultrathin display panel
View Patent ↗A display system, with a structural part, including a rear panel, and a light emitting device physically attached to the rear panel over a surface of the rear panel, where the surface of the rear panel comprises the entire surface to be illuminated by the light emitting device and a pixelated spatial light modulator part, coupled between the light emitting device, and a viewing area, modulating a light created by said light emitting device.
1. A display system, comprising:
a structural part, including a plastic material forming a rear panel, and
a light emitting device physically attached to the rear panel over a surface of the rear panel, including a conductive reflective coating connected directly to the rear panel and a non-conductive layer, attached to said conductive reflective coating, the conductive reflective coating connected directly to the rear panel and a non-conductive layer, attached to said conductive reflective coating attached to said rear panel to add structural integrity to the rear panel,
a signal line, connected to said conductive reflective coating and curved to conform to a curved contour of a curved side portion of said structural part, a dielectric layer connected to said non conductive layer, a light emissive layer connected to said dielectric layer, and a transparent conductive layer over the light emissive layer, with a second signal line connected thereto,
the light emitting device emitting light across its area when electrically energized between said signal line and said second signal line; and
a pixelated spatial light modulator part, connected directly to the light emitting device, and modulating a light created by said light emitting device to create light in a viewing area.
2. The system as in claim 1 , wherein said spatial light modulator is liquid crystal or an electro-wetting device.
3. The system as in claim 1 , wherein said light emissive layer is a flexible material.
4. The system as in claim 1 , wherein said structural part includes a flat surface and an indentation formed in the flat surface below the flat surface, where the indentation holds the entirety of the light emitting device.
5. The system as in claim 3 , wherein the spatial light modulator also extends across said flat surface, and is also located entirely in said indentation.
6. The system as in claim 1 , wherein the rear panel is optically opaque.
7. The system as in claim 1 , wherein the rear panel is optically transparent.
8. The system as in claim 7 , wherein the light emitting device emits light from both sides of the rear panel.
