摘要
An electronic display may include a memory formed in an active area of the electronic display or formed in integrated circuitry of the electronic display that is outside of the active area. The memory may store a digital data signal indicative of a value within a data range. The electronic display may include a driver disposed in the active area, where the driver may generate one or more analog electrical signals in response to the digital data signal. The electronic display may also include a light-modulating device disposed on the active area, where the light-modulating device may emit light based at least in part on the one or more analog electrical signals.

This application claims priority to U.S. Provisional Patent Application No. 62/668,709, entitled “SYSTEMS AND METHODS FOR MEMORY CIRCUITRY IN AN ELECTRONIC DISPLAY,” filed on May 8, 2018, which is incorporated herein by reference in its entirety for all purposes.
A summary of certain embodiments disclosed herein is set forth below. It should be understood that these aspects are presented merely to provide the reader with a brief summary of these certain embodiments and that these aspects are not intended to limit the scope of this disclosure. Indeed, this disclosure may encompass a variety of aspects that may not be set forth below.
Methods and systems for reducing bandwidths, or amounts simultaneously transmitted, of image data transmitted and processed to prepare an image for presentation on an electronic display by implementing memory in pixels of the electronic display may provide immense value. Such an implementation of memory in the pixels may permit an elimination of a frame buffer associated with the electronic display. Having memory in the pixels may lessen the design complexity of electronic displays, as well, because the less image data that is concurrently transmitted to a pixel array of an electronic display, the simpler an electronic display may be designed. For example, the pixels may be programmed in smaller groups because memory in the pixel stores the values until a time of presentation of the image.
