A function that utilizes only part of the screen, thus reducing power consumption.
General Description
Feature
EM65570 is one of the industry’s most advanced wide-screen STN-LCD drivers for
65K-color display. It also has a built-in display RAM, a power supply circuit for LCD
drive, an LCD controller circuit, and supports EEPROM function for programming
information to tune the V
compacting system design. EM65570 contributes to compact system design and with
its partial display function, low power consumption is achieved.
