20080211973 | Spectrum Sequential Display Having Reduced Cross Talk - A color display device, a drive circuit for a color display device, a method, a signal and a computer-readable medium for reducing electro-optical cross talk that occurs in a display that is operated in Spectrum Sequential mode is disclosed. The invention eliminates annoying visible artefacts, such as contouring, noise, or color deviation, which normally are introduced by this cross talk by compensating for the cross talk. According to embodiments of the invention, a drive signal (R′,G′,B′) to drive picture elements of the display is altered in video processing circuitry (MPC, XTC, SC) and/or software, in dependence on one or more properties of different spectra from a light source ( | 09-04-2008 |
