1. General
description
EM65568 is one of the industry's most advanced wide-screen STN-LCD drivers for 4096-color display. The industry's first
sub-screen display function makes it possible to display different images and data in a sub-screen inside the main LCD screen.
It also has a built-in display RAM, a power supply circuit for LCD drive, and an LCD controller circuit, therefore contributing
to compact system design. Its partial display function realizes low power consumption.
*Partial display function: A function that utilizes only part of the screen, thus reducing power consumption.
