4D Systems GOLDELOX & PICASO Embedded 4DGL Graphics Controllers are custom embedded graphics controllers designed to interface with many popular OLED and LCD display panels. Powerful graphics, text, image, animation, and countless more features are built right inside these chips. The GOLDELOX and PICASO controllers offer simple plug-n-play interfaces to many 8-bit and 16-bit 80-Series color LCD and OLED displays. These chips are designed to work with minimal design effort and all of the data and control signals are provided to interface directly to the display. The user can simply choose a display and interface it to the GOLDELOX or PICASO on the application board. This offers enormous advantage to the designer in development time and cost saving and takes away all of the burden of low level design.
