The performances of the short arm centrifuge test bed and its display control system were introduced. The core control chip of the short arm centrifuge test bed is the single chip microcomputer PIC16F74. By analyzing the relationship among the clock and the instructional cycle

and the demand of T6963C to single chip microcomputer

the interface method of LCD module based on T6963C controller with the PIC single chip microcomputer was obtained and applied to short arm centrifuge test bed successfully.
