Summary
The development of the light sources involved two main parts, the design of the optics, done by In-Vision and the design of the electronics by Visitech.
Starting from the Phase 1 engine (1920 x 1080 pixels) new DLP electronics has been developed for higher resolution DMDs (Figure 18). Electronics for WUXGA (1920 x 1200 pixels) is finished in design and manufacturing. The design utilizes similar generic design as for the Phase 1 Light Engine, but Firmware to support the higher number of pixels, and thus higher data rates, have been developed.
New LED control and driver electronics for “Light Dosing” has been completed in design and manufacturing. Visitech’s Light Dosing™ technology ensures precise and long term stable light intensity by using optical feedback to calculate the appropriate light dose for each colour depth bit plane.
The new LED control and driver electronics is based on a new concept for digital control of the LED, for which VIS has applied for a patent. Further implementation and application of higher resolution DMDs depend on the providing of higher resolution DMDs by the producer to VIS.
