The internal LCD controller of the S3C44B0X can support black and white LCDs with a resolution of 2 bits (4 gray levels) or 4 bits (16 gray levels) per pixel. It can also support color LCDs with a resolution of 8 bits (256 colors) per pixel. The LCD controller can be programmed to support different LCD requirements, such as the number of pixels per row and column, the data bus width, the interface timing and the refresh rate.
The S3C44B0X LCD controller supports both monochrome and color displays, offering 2‑bit (4‑level), 4‑bit (16‑level) and 8‑bit (256‑color) pixel depths. It can drive a variety of LCD panels, from small 320 × 240 screens up to large 4096 × 1024 color panels, and includes low‑power SL IDLE mode.
The manual details the external interface signals (VFRAME, VTLINE, VCLK, etc.), the register map for configuring display parameters, and the color lookup tables (REDLUT, GREENLUT, BLUELUT) used to define palette entries. It also explains how to set memory addressing for different screen sizes and how to adjust display depth and scan modes. This manual is written in Chinese.
