about project

Intrigue architected and developed a web-enabled embedded multimedia system for testing and developing OLED TFT flat panel displays. The system is controlled through a web interface. It has embedded video storage and can play various compressed video and image files, sending them to a universal display connector. The system has a wide range of GUI adjustable power supplies necessary for experimentation with display drivers. The system is uses TI DaVinci media processor for video compression/decompression and networking, as well as Xilinx FPGAs for input and output digital image processing.

Connection to Display Panel

The interface PCB provides custom interface to the display driver chips. The interface PCB is consumed with each display since the driver chip connections are bonded to the PCB. When display changes, only the interface PCB needs to be redesigned.
