Round Memory LCDs
12 June 2012
Avnet Embedded is introducing the new Memory LCD type LS010B7DH01 from Sharp.
This ultra low-power display incorporates, for the first time, a circular active display area of 12,868 pixels. At a diameter of 1in (2.54 cm) with 128 x 128 pixel the new Memory LCD provides excellent resolution and a sufficient display area for the full graphic black and white visualisation of content. Excellent legibility in all light conditions is ensured by the 14:1 contrast ratio of the high reflectivity LCD. Thanks to the display areas 0.25% transmissive ratio, the new Memory LCD can be fitted with a backlight so that the screen content can be easily recognised in the dark.
With its circular shape, the LS010B7DH01 is particularly suitable for wrist-worn devices requiring extended runtimes. These include not only wristwatches but also endurance and mountain sports computers as well as medical tele-monitoring devices. The circular Memory LCD can also be used as a screen for E-bike speedometers, fitness equipment, or thermostats.
Like all Memory LCDs, the LS010B7DH01 features very low power consumption with a mere 10µW for static images, and, even with a regular display content refresh rate of 1 Hertz, the LCD consumes only 45µW. Therefore, power consumption is approximately 1% of that of conventional transmissive TFT LCDs of the same size.
When compared to conventional reflective displays, the Memory LCD needs only a tenth of the power. Furthermore, traditional LCDs are currently unavailable in this unorthodox, circular shape.
