Sharp showcases a 1" smartwatch battery-saving display that has 8 colors and no backlight
Sharp seems to be on a bender to revolutionize smart device screens. First, it released the “bezelless phone” – Aquos Crystal, then, we heard rumors about the company working on a 4K (4096 x 2160) smartphone screen panel, as well as re-working how the protective glass is manufactured, in an attempt to make it clearer. Now, Sharp showed a 1" smartwatch display prototype, which will probably be a big deal once it gets to its final stage.
The panel replaces the well-known backlight with a reflective layer – this means that any light that hits the watch will be then used to illuminate the display from the inside and show the image. Aside from saving a lot of battery power, this will also help make the watch view-able in direct sunlight, as more incoming light would mean more backside illumination. The major drawback is, and we assume Sharp would be looking for a way around this, the fact that the display can not be viewed in the dark.
It is said that Sharp has been in talks with various manufacturers over implementing the tech in a smartwatch, though, there is yet no word on whether any of them agreed to a partnership.

The other power-saving feature, employed by Sharp's prototype, is the implementation of semiconductor memory – a random access memory with fast access times, which, in this case, is used for storing and reproducing the on-screen image, reducing power consumption in the process. For the picture, Sharp uses a LTPS (low temperature polysilicon) LCD display with only 8 colors.
