A display driver device () 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 () and portions of drive sequences () that are downloadable and/or updated in real time depending on various inputs ().

Systems, methods and devices for providing sequence based display drivers

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.

Systems and methods for driving a display

Updating an image displayed on a display device. The display device includes pixels in a pixel array. A system comprising a display subsystem for executing commands and displaying images, said display subsystem comprising a parser for receiving the image frame data, wherein the parser extracts updated image data and the commands. The system includes a storage device for storing the updated image data in a updated cache location according to the commands. The system includes a loader for reading the commands to identify and fetch the updated image data from the storage device. The system includes display backplane circuitry for receiving the updated image data from the loader and for updating pixel driver circuity for pixels within the updated image data. The embodiments herein can be used for driving micro-displays such as LCoS micro-LED displays.
