The innovative Memory LCDs are based on Sharp´s own Continuous Grain Silicon (CGS) technology. This enables each pixel to be equipped with a 1-bit memory which stores the image information uploaded onto the screen. Image information therefore only needs to be written in those pixels in which the content has changed compared to the previous picture frame. As reflective displays, Memory LCDs do not require a backlight system. Therefore, Memory LCDs have only 0.8% of the power consumption compared to a conventional display.
This minimal consumption of power allows small solar cells to supply sufficient electricity to run the Memory LCDs. This is an ideal solution for small portable applications as well as applications with a low power demand. Sizes of 3.42 cm (1.35”) and 6.85 cm (2.7”) with a resolution of 400 x 240 dots and 7.46 cm (2.94”) with a resolution of 456 x 240 dots are already available. A 15.29 cm (6.02”) version will be available soon. Transflective versions with a backlight system and memory LCDs with capacitive touch panels are under development.
