Diagnosis of the RSDS video signals on TFT color screens

This work takes place within the more general framework of the design of a test bench which detects the failing signals (control and video) on the printed circuit boards which control the TFT-LCD color screens embedded inside the cars. It describes the design of an innovating diagnosis method of the video signals (RSDS), resting on a Frame Rate Control (FRC) algorithm and a verification by checksum. The method was developed in VHDL language, on a FPGA target (spartan3E) embedded on a NEXYS2 board (Digilent).
