EM65570
68COM/ 98SEG 65K Color STN LCD Driver
1 General Description
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 VLCD offset voltage to get the best contrast which helps in
compacting system design. EM65570 contributes to compact system design and with
its partial display function, low power consumption is achieved.
Its “partial display”1 function realizes results in low power consumption.
