Latest Patents
Lippmann's latest patents include a "Method of manufacturing a cover of a backlit display using fluorescing materials." This invention allows for one or more colors to be properly illuminated in a backlit display. It features a light source that emits light from the backside of a substrate, with a selectively applied opaque layer that prevents light from passing through specific portions of the substrate. Additionally, fluorescing materials are incorporated into the substrate to diffuse the light and alter its color.
Another significant patent is the "Method and apparatus for correcting optical non-uniformities in a light emitting diode." This invention adjusts the spectral characteristics of LEDs by placing a filter in the light emission path. The filter can be printed on the lens of the LED or on a cap attached to the LED using inkjet printing or other methods. The specific ink colors for the filter are chosen based on the deviation of each LED from a specified tolerance, creating a high degree of color and intensity uniformity without the need for labor-intensive binning.
