Sharp LCD development of new memory power consumption lower than the same-size LCD panel 130 times

The liquid crystal display (LCD) pixel (pixels) is relatively large, it is possible the memory integrated in each pixel (pixel site) of the active memory backplane (active memory backplane) in; Japans Sharp (Sharp) already in a 96 × 96 pixel monochrome LCD on a small target to achieve the above, and LM339AD datasheet and known as the power consumption than the standard size LCD panel with 130 times lower.

By adding memory in each pixel, when the frame (frame) and LM339AD price and the time frame between the content transformation, the data sent to the display only; and LM339AD suppliers and most of the liquid crystal display through a micro-controller needs to Frequency 50 ~ 60Hz frame in between frame and rewrite the entire contents of the screen, and even the screen may not change. And that is such redundant data transmission, will waste a lot of power consumption.

Sharp said its research and development of 1.35-inch memory LCD, the operation of the power consumption is only about 15 microwatts (microwatt); and standard LCD monitor power consumption is about 2 mW (milliwatt). The LCD is a Sharp proprietary memory continuous silicon particles (Continuous Grain Silicon) technology, so different from the other reflective display, new LCD does not require polarizers (polarisers).

And because it is using a special liquid crystal materials, reflective and 50%, the picture is black and white pixels produced by the state transformation; addition Sharp said, because of low power consumption, so long as there is small enough to provide the solar cell kinds of memory needed to power LCD. This display is suitable for portable applications, such as watches, medical devices such as pulse count, or volume label, the samples provided in the second quarter.
