A control system circuits based on static random access memory(SRAM) for grating light modulator (GLM) ar-ray is proposed in this paper. The process and operating principle of the GLM are introduced. The operating principle and technique parameters of the control system circuits are analyzed. With Cadence software and CSMC's 0.5μm process, a 8×8 control system circuits is designed and fabricated. The experimental results indicate that the output vohage can be refreshed or hold by the active matrix addressing based on SRAM; and the GLM can be controlled well by the fabricated control system circuits, which confirms the functional correctness of the designed control system circuits. The result incticates that if both the row and column driving circuits can work well in 248MHz clock frequency and the switch time of the active matrix unite is less than 121ns, this designed control system circuits can be applied in projection display which has 1920 × 1080 resolution, 30Hz frame frequency and 256 grayscale.
