Driving the ATK-MD0430 display module is, in essence, driving the NT35510 LCD-driver IC. The NT35510 contains its own display RAM (GRAM) with a total capacity of 1 244 160 bytes (480 × 864 × 24 bits ÷ 8). This is large enough to operate an LCD at 480 × 864 resolution with a full 24-bit (16.7 million-colour) data bus.
The ATK-MD0430 board, however, runs the LCD in 16-bit RGB565 mode (65 k colours) and drives a 480 × 800 panel. In RGB565, a 16-bit colour word is stored in the NT35510’s GRAM, which still has a 24-bit-wide layout. The relationship among:
