Design of Driving Circuit for Flat Panel Display Based on FPGA

A design method of a driving circuit for flat panel display based on FPGA is introduced.Some circuit functions,such as digital gamma correction,time base correction,timing generator,phase-lock loop,I2C control,can be realized efficiently with FPGA instead of all the functions of integrated chips.The signal processing used digital way instead of traditional analog technology.So the circuit is simplified.It can fulfill the timing and control requirements and is versatile at contro1.This design can be universally used because it can drive most FPD,and can be well transplanted to larger scale FPD driving after extending the design with SDRAM and designing abundant extended signal interfaces.High resolution liquid crystal display projection LCX029CPT is used to verify the driving circuit,and the driving circuit realizes good display result.
