US Patent 7300194 Summary

• Title: Light emitting panel assemblies
• Inventors: Jeffery R. Parker
• Original Assignee: Solid State Opto Ltd
• Current Assignee: Innovative Display Technologies LLC
• Filing Date: October 6, 2005 (for application US11/245,408)
• Issue Date: November 27, 2007
• Abstract: Light emitting assemblies are described, featuring at least one light source and a film, sheet, plate, or substrate with precisely shaped optical elements or deformities on its surface. These elements include reflective or refractive surfaces designed to control the output ray angle distribution of the emitted light. The film, sheet, plate, or substrate can be placed near a light-emitting panel, with an air gap in between, or over a cavity in a tray where the light source is located, and from which light is emitted.

Plain-Language Overview of Independent Claims:

• Claim 1: This claim describes a light-emitting assembly. It includes a panel that emits light and at least one light source. Crucially, there's a separate film, sheet, plate, or substrate positioned near the panel's light-emitting surface, with an air gap between them. This separate element has specially designed reflective or refractive surfaces with optical elements or deformities. These features are specifically for controlling the emitted light so that at least some of it passes through a liquid crystal display (LCD) with minimal light loss.
• Claim 16: This claim focuses on a light-emitting assembly that incorporates a tray. The tray forms a cavity or recess, and at least one light source is placed inside this cavity. A film, sheet, plate, or substrate is positioned over the cavity, allowing light from the source to pass through. Similar to Claim 1, this film, sheet, plate, or substrate has well-defined optical elements or deformities on its reflective or refractive surfaces, engineered to control the emitted light for low-loss transmission through an LCD.
• Claim 28: This claim details a light-emitting assembly comprising at least one light source and a transparent film, sheet, plate, or substrate. This transparent element has distinct top and bottom surfaces, each containing multiple precisely shaped optical elements or deformities. At least some of these elements on either the top or bottom surface possess reflective or refractive properties. Their purpose is to control the emitted light, directing some of it to pass through an LCD with low loss.
• Claim 31: This claim describes a light-emitting assembly with a tray forming a cavity or recess, and at least one light source within it. A film, sheet, plate, or substrate is placed over the cavity, through which the light is emitted. This film, sheet, plate, or substrate has one or more reflective or refractive surfaces that are well-defined optical elements or deformities. These elements are designed to control the light output ray angle distribution to suit a particular application.
