Alias: D-latch BufferAlias: SR-latch Buffer
Definition
A buffer for displays which allows a device to write to a display without the new data being instantly shown on the display. This allows full frames to be written to a screen at once.
SR-latch buffer: A buffer using SR-latches, typically where all pixels are reset at once, and set to "1" when triggered.
D-latch buffer: More flexible than an SR-latch buffer, allowing pixels to be set to "0" or "1" when triggered.
