This paper presents the design and implementation of a chromatic TFT-LCD module based on ARM9 processor. To resolve the real-time display
the image and character library is stored in the NAND Flash memory
and the memory capacity is 64 Mbytes. Depending on different requirements
the image and character library can be updated. The 24 bit color image of raw pixel can be displayed on the LCD directly. The image decoding for the JPEG format is presented
so the image of JPEG format can also be displayed. The module communicates with control system using the serial port. Receiving different kind of instructions
image and character in the flash memory can be displayed respectively. The module was tested on the TFT-LCD LQ080V3DG01
and the result shows that the module works reliably. The module has been applied to the image display system.
