Reflective LCD with Memory in Pixel Structure

Summary

This chapter traces the development of Memory in pixel (MIP) reflective display technologies and their applications. It reviews the basic technology behind an MIP circuit and its pixel design and liquid crystal displays (LCD) optical design and the design characteristics of available market products and their super low power operations. The chapter also reviews selected applications of MIP reflective LCDs and previews future possibilities for this technology and its applications. It provides an overview of the MIP technology, how it works, and how to drive it. A MIP LCD utilizes a static random‐access memory circuit as digital memory, and an LC on the memory operates as a digital optical shutter. The so‐called “area coverage modulation” method expresses grayscale by combining dots, as has been the case with printing devices. A reflective LCD needs to have light scattering functionality because, without this property, it looks like a mirror.
