Few things can cause the same anxiety as the ‘low battery’ symbol flashing on a mobile telephone. A number of effective low power display methods, LCDs being one of them, exist today. However, it has been the availability of video and animation in almost all applications, as well as the diminishing mass of most portable products, that is driving the need for even greater power performance. The same factors that make Liquavista’s displays intrinsically the brightest and most vivid, also provide us with the solution to greater power performance.
Because the displays are so significantly brighter than competing techniques, they require less supplimentary illumination. In one of the most demanding of applications, mobile handsets, for example, the backlighting system of a contemporary display may account for more than 20x the power consumption of the display itself.
Other techniques rely on bi-stability to offer low power stand-by modes. However, this has its own disadvantages, as generating video performance with a bi-stable pixel, leads to very high complexity and losses in efficiency, and/or a significant rise in power consumption.
