EM65571
130COM/128SEG 65K Color STN LCD Driver
1 General Description
The EM65571 is one of the industry’s most advanced wide-screen STN-LCD drivers for
65K-color displays. It has a built-in display RAM, a power supply circuit for LCD drive,
an LCD controller circuit, and support for LCD cell tolerance compensation of VLCD by
external pin selection. It also supports the EEPROM function for programming
information to tune VLCD offset voltage to get the best contrast. Therefore, this
contributes to a compact system design. In addition, its partial display function realizes
low power consumption.
*Partial display function: A function that utilizes only part of the screen, thus reducing
power consumption.
