Using memory-in-pixel (MIP) technology, we have developed high image quality reflective LCDs with super-low power consumption suitable for wearable devices. Two types of MIP circuits have been developed: one is a memory drive type and the other is a hybrid type in which the pixel circuit is switchable between memory drive and normal drive. The memory drive type has 6-bit-per-pixel (bpp) memory and the resolution is 182-pixels-per-inch (ppi). The hybrid type has 3-bpp memory and can also display 18-bit color when selecting normal drive circuit and the resolution is 238.5-ppi.
