  • Publication number: 20240127735
    Abstract: A display driver device (210) receives a downloadable “sequence” for dynamically reconfiguring displayed image characteristics in an image system. The display driver device comprises one or more storage devices, for example, memory devices, for storing image data (218) and portions of drive sequences (219) that are downloadable and/or updated in real time depending on various inputs (214).

  • Patent number: 11893957
    Abstract: An image system dynamically updates drive sequences in an image system. Drive sequences are image display settings or display driving characteristics with which a display is operated. The image system may determine the drive sequence at least partially based on input from one or more sensors. For example, the image system may include sensors such as an inertial measurement unit, a light sensor, a camera, a temperature sensor, or other sensors from which sensor data may be collected. The image system may analyze the sensor data to calculate drive sequence settings or to select a drive sequence from a number of predetermined drive sequences. Displaying image content on a display includes providing the display with image data and includes operating the display with various drive sequences.

  • Publication number: 20230306930
    Abstract: A system for updating an image on a display device is disclosed. The display device includes pixels in a pixel array. The system includes a display subsystem for executing commands and displaying images, the display subsystem also includes a parser for receiving image frame data, and extracting updated image data and commands. A storage device is used for storing the updated image data in an updated cache location according to the commands. A loader is used for reading the commands to identify and fetch the updated image data from the storage device. Display backplane circuitry is used for receiving the updated image data from the loader and for updating pixel driver circuitry for pixels within the updated image data. The examples described are ideal for driving micro-displays such as LCoS micro-LED displays.
