Sharp has developed a reflective liquid crystal display panel for wearable computer devices, such as smart-watches, that consumes 0.1% the energy of current backlit panels. The Japanese electronics maker will mass-produce the panel in Japan by next spring and ship it to device makers domestically and abroad.
The panels incorporate memory chips and can save power on retrieving data by storing images for a certain amount of time. Panels account for more than 30% of the power usage of current wearable devices. With the new model, devices will be able to function for 30% longer before recharging.
