Popis: The technology of time-sharing driver type LED has become very mature,but parasitic element will be produced in the circuit board level during the operation of the high frequency hardware circuit,which leads to picture crosstalk.The reasons of the parasitic capacitance in the actual circuit are analysed,then the voltage regulator circuit is adopted to eliminate the inter-row parasitic capacitance,and column driver circuit with two state gate output is designed based on FPGA.The experimental result shows that the method proposed can eliminate the image crosstalk phenomenon completely compared with the traditional time-sharing driver type LED.
