說(shuō)明書(shū)
As described above, a display implementing memory-in-pixel techniques may implement a variety of pixel circuitry embodiments and a variety of memory circuitry embodiments to achieve benefits described earlier in this disclosure. An example embodiment is a memory circuit supporting a binary pulse width emission scheme, where digital data stored in the memory circuit is outputted to the driver circuit to control emission of light from a pixel. As a reminder, the binary pulse width emission scheme works in tandem with a clocking signal, for example, a bit-plane clock, to assign contribution weights to the different portions of digital data transmitted from the memory circuit. In some embodiments, the clocking signal is used to clock a register to output stored digital data from a memory circuit. However, in some embodiments, a system clock and/or a row driver 60 may control light emission duration through a length of time that an emission-enabling signal is enabled.
To help illustrate the memory circuit that facilitates in controlling emission via an emit-enable signal, a sub-pixel 72 including memory circuitry 400A, analog driver circuitry 402, and light-emitting circuitry 404 is shown in
