  • Patent number: 11640805
    Abstract: A device and method of an image processing system where a Field Sequential Color Delta Sigma Pulse Density Modulation is used for digital displays, where the digital displays are non-emissive. The device and method are a digital driving solution using Delta Sigma Encoding where N bit-per-component symbols at F1 frame-rate-per-second are represented using M bits-per-component symbols at F2 frame-rate-per-second, where N?M and F2?F1. The F2 frames are sent to a sequential color picker, which outputs frames with one color, followed by the next in a sequential pattern which reduces power consumption, increases color saturation, increases contrast, and increases brightness.
