Title: Innovations of Steven E Stark
Introduction
Steven E Stark is an accomplished inventor based in Portland, OR (US). He holds a total of 3 patents that showcase his contributions to the field of display technology. His work primarily focuses on enhancing the performance and efficiency of projection systems.
Latest Patents
One of Stark's latest patents is titled "Lamp power pulse modulation in color sequential projection displays." This invention involves a frame sequential color display projection system that utilizes an arc lamp with a predetermined power rating. The system is designed to provide a source of polychromatic light that passes through a color wheel, which sequentially delivers red, green, blue, and optionally white light colors during specific time periods. A display controller is synchronized with the color wheel to generate color image data, while a light valve, such as a Digital Micromirror Device (DMD), processes this data to create the frame sequential color display. Additionally, a lamp ballast is synchronized with the color wheel to provide both nominal and boosted power levels to the arc lamp, ensuring a brighter, color-adjusted display without exceeding the lamp's average power rating.
