TLDR
In this paper, the development of moving picture breakups can be suppressed with a display producing a time-division gray-scale display, without having to carry out a display scanning operation for every display.
Abstract
A memory circuit is caused to retain a voltage corresponding to largest tone data, then a voltage corresponding to tone data except for the largest tone data is applied to a liquid crystal element, and the voltage corresponding to the largest tone data is supplied from the memory circuit to the liquid crystal element. The development of moving picture breakups can be suppressed with a display producing a time-division gray-scale display, without having to carry out a display scanning operation for every display.

Electrooptic device and electronic equipment

TL;DR: In this article, a pixel driver connects a first voltage signal line or a second voltage signal signal line to a pixel, and display is performed by a potential difference between the reference voltage and a first-or second-voltage signal.
Patent

Picture display device

TL;DR: In this paper, the authors proposed a method to improve display quality by preventing unevenness of luminance or a flicker from occurring, preventing the brightness of a display from being reduced and preventing such a failure that the natual hue of a picture which should be displayed on a screen is deteriorated from occurring based on the difference of the visual sense of a person with respect to respective colors.
