S3C2410A LCD CONTROLLER
15-1
15 LCD CONTROLLER
OVERVIEW
The LCD controller in the S3C2410A consists of the logic for transferring LCD image data from a video buffer located
in system memory to an external LCD driver.
The LCD controller supports monochrome, 2-bit per pixel (4-level gray scale) or 4-bit per pixel (16-level gray scale)
mode on a monochrome LCD, using a time-based dithering algorithm and Frame Rate Control (FRC) method and it
can be interfaced with a color LCD panel at 8-bit per pixel (256-level color) and 12-bit per pixel (4096-level color) for
interfacing with STN LCD.
It can support 1-bit per pixel, 2-bit per pixel, 4-bit per pixel, and 8-bit per pixel for interfacing with the palettized TFT
color LCD panel, and 16-bit per pixel and 24-bit per pixel for non-palettized true-color display.
The LCD controller can be programmed to support different requirements on the screen related to the number of
horizontal and vertical pixels, data line width for the data interface, interface timing, and refresh rate.
