Memory-in-Pixels

Memory in Pixel LCDs
High Ambient-Light Performance. Long Battery Life.

Memory-in-Pixel LCD Technology

High Resolution. Long Battery Life. Thin, Lightweight Design.

The Memory-in-Pixel LCD combines matrix technology with a one-bit memory circuit embedded into every pixel, so information is retained once it's written.

This allows the design of products with ultra-low power consumption and long battery life. It also delivers higher resolution, shock, and temperature tolerance than E-Ink (electronic paper) displays.

Key Sharp Memory-in-Pixel Features

① Ultra Low Power Consumption

Microwatt range (Typ.)

② High Readability

Viewable in any light, from edge-of-vision to brightest sunlight
Reflective, plus Transflective models

③ Simple Interface

Single 5V or 3.3V supply
3-wire SPI interface

④ Wide/Symmetrical Viewing Angle

Typically 120° × 120°

 

Ultra-low Power Consumption

Requires just 1/40 ～ 1/80 of an STN LCD’s power consumption and 1/1000 of an AM-TFT LCD’s power consumption.

Excellent reflective display performance without the need for a backlight.

Embedded pixel memory stores graphic data, so continuous refresh is not required for a still image. Less power is needed during refresh than with traditional graphic displays.

Data Memory in Each Pixel

 

Embedded driver and peripheral circuits are monolithic on the TFT glass. Each pixel contains 1-bit memory.

Fast Image Refresh Time

MIP LCDs have fast response times for scrolling text and moving images.

Cholesteric, STN, and E-Ink displays require longer times to update the display image (several hundred milliseconds).

Simple 3-Wire Interface

Simple 3-wire Serial I/F connectivity (SI, SCS, SCLK)

Only a single 3 V (1.28” and smaller) or 5 V (1.8” and larger) power supply is required

Only 3 external capacitors are required

Fewer peripheral components = simplified design process
