ConnectCore 9M 2443 & Wi-9M 2443 Hardware Reference
The LCD controller of the S3C2443 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 palletized TFT color LCD panel, and 16-bit per pixel and 24-bit
per pixel for non-palletized 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.
