FPGA and LSI58 are main and important LSI of D Board. and these are BGA type 2. FPGA has two functions. One is receiving LVDS signal, RGB processing and Sync Control. Another is Discharge Control. FPGA outputs RGB signal to LSI58 and Scan Control signal, Sustain Control signal and DATA Driver signal to SC, SS, C Board respectively. 3. LSI58 receives RGB signal from FPGA. After processing image data and Sub Field processing, LSI58 outputs Video data to each C Board. 4. DDR-SDRAM is used for LSI58 to process signals. 5. PROM has program and data for FPGA. 6. Flash-ROM has some preset data for FPGA and LSI58. 7. LATCH, SFVRST, SFRST, FPCLK, FPDATA are control signals between FPGA and LSI58.
