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.

說(shuō)明書

To elaborate on operating the pixel array 69 with memory-in-pixel to display images, an example of a display system 52A implementing memory-in-pixel having a timing controller 54 linked through communicative link 68 to a row driver 60 and/or a column driver 62, is shown in FIG. 6. The display system 52A includes a pixel array 69 of L rows by M columns with one or more pixels 70 each having sub-pixels 72 corresponding to color channels of the electronic display 18, for example, a red sub-pixel 72R, a green sub-pixel 72G, and a blue sub-pixel 72B, where each of the sub-pixels 72 includes a memory 78 to store up to N bits and a driver (DRV) 80 to operate the sub-pixel 72 to emit light, is shown in FIG. 6. It should be appreciated that the depicted display system 52A is merely intended to be illustrative and not limiting. For example, in some embodiments, the pixel array 69 may include sub-pixels 72 to emit various amounts of cyan, yellow, and magenta light corresponding to cyan-yellow-magenta color channels instead of, or in addition to, the red-green-blue color channels.
