Sharp Microelectronics - The New SHARP Memory LCD Technology - 16 November 2012

PNLC and HR-TFT Modules
Sharp's Polymer Networked Liquid Crystal (PNLC) - type Memory LCD is composed of a PNLC layer formed between a transparent surface electrode and mirror-reflective pixel electrodes.
The PNLC module uses a scattering mode and does not require polarizers, which results in a very bright reflective display. A 1-bit memory circuit is embedded into each pixel, which retains the pixel information once it's written.

Sharp's high-contrast HR-TFT technology adds a polarizer to the top layer to greatly enhance the contrast of the display. The black level is dramatically enhanced, resulting in an almost paper-like black and white image.

Features

Delivers a high-contrast, high-resolution display allowing for denser content than many other types of same-sized LCDs
eliminates sweeping images or "ghosting"
An embedded 1-bit memory in every pixel enables each pixel to hold state while requiring very little current
Delivers an "always on" display that uses little power (only single supply voltage required), helps create products with longer battery life
Response time of the Memory LCD makes it fast enough to display motion video
Bold crisp black images delivered by high-resolution capability in a small diagonal display
A lightweight, two-glass design plus an integrated driver in the panel provides an exceptionally thin module
