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.

說明書

To explain differently, FIG. 25 includes a bit-plane graph 604 representative of a binary pulse width modulation emission scheme with two reorderings implemented with three color channels. As depicted, the bit-plane graph 582, which corresponds to the two reoderings, is represented in the bit-plane graph 604 over time and with three color channels of one pixel 70. The row driver 60 may time emissions in terms of quadrants, where, for a two-reordering case, one quadrant 606 may approximately correspond to one-fourth of emission time (e.g., ?n, where n is equal to the number of reorderings). These quadrants 606 may parallel the previously described operational modes. As the time increases, the electronic display 18 may change emission priority—in other words, higher emission priority may be given to the two most significant bits of image data for a particular pixel 70 during emission than is given to the other bits. The electronic display 18, in some embodiments, may manage emission based on a comparison of the most significant bits to a value represented by a counter, incrementing up from binary state “00” to binary state “11” on an edge (e.g., rising or falling edge) a clocking signal (e.g., where one period of the clocking signal corresponds to the duration of one quadrant). Thus, in these embodiments, in terms of the sub-pixels 72 of the pixel 70, for the first quadrant 606A, if the two most significant bits (MSBs) equal binary state “00,” the sub-pixel 72 may emit according to the bit-plane 608 (e.g., according to binary data as stored in memory 78 represented by the, but if the two most significant bits equal binary states “11,” “01,” and/or “10,” the sub-pixel emits light for the duration of the channel's emission period (e.g., a first color channel corresponds to time duration 609) of the first quadrant 606, as generally summarized in output logic outline 610.
