- AlanYx 5y agoIs that the same technology as RLCD, or is it a different type of display?
- goosedragons 5y agoPretty much. Memory LCD adds a bit of memory to each pixel so it doesn't need to refresh if it hasn't changed. Otherwise the same.
- AlanYx 5y agoThanks! I found a whitepaper describing the tech: https://www.sharpmemorylcd.com/resources/Polarizer-free_Reflective_LCD_White_Paper.pdf https://www.sharpmemorylcd.com/resources/Polarizer-free_Refl... In terms of display properties it's in a pretty sweet spot between eink (electrophoretic displays) and conventional RLCD. Slightly lower contrast than conventional RLCD but much better reflectance (roughly on par with eink).
