LH15A1
LCD driver with built-in RAM for 256-color STN-LCDs
Outline
LH15A1 is one of the industry's most advanced wide-screen STN-LCD drivers for 256-color display. The industry's first
subscreen display function makes it possible to display different images and data in a subscreen 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.
