No crazy +/- 40V lines, no external driver circuitry, and extremely low power. Not as low power as E Ink, but since you don’t need to drive wacky voltages, your power budget math will come out the same or better.
- robin_reala 8y agoI’ve never seen one in real life. How are the display characteristics compared to eInk?
- ehead 8y agoIf you’ve ever seen an OG Pebble, you’ve seen that display. It looks like a better resolution gameboy display. Very little space between pixels. Some models are different, though, and basically turn into a mirror when their pixels are turned on, rather than become matte black. Adafruit sells a dev board for 25 bucks. Perfect for low power wearables, much better than E Ink.
- Avamander 8y agoI disagree that memory LCD is better than e-ink. Although, mLCD can do colors and better refresh rates but the colors are washed out, in sunlight grayscale e-ink is much much more readable in my opinion. mLCD also consumes more power in certain cases which isn't ideal.
- ByThyGrace 8y agoIs this tech relatively new? Is it merchandised as "memory LCD"? I would like to know when searching for e-reader displays in the future.
- dbuder 8y agoIt is not new and rarely mentioned in advertising or product information. The memory LCD I've seen are too small for a normal e-reader but if you are doing a large production run you can have something custom made.
