| Abstract |
This paper presents a PLD design of Gray Mode Graphic STN LCD drive circuit using PC interface. The proposed LCD drive circuit doesn"t use microprocessor for the convenience of users. Thus, the LCD drive circuit can transfer efficiently image data created under PC to LCD. The LCD drive circuit which is modelled in schematic capture, AHDL and VHDL is simulated in functionally through the use of ALTERA MAX+PLUS Ⅱ. Also, timing simulation is performed by ALTERA EPM7192SQC160-15 PLD implementation. The PC interface part have been programmed in MS-Visual C++ 6.0. The validity and efficiency of the proposed LCD drive circuit have been verified by test board. After comparing this LCD drive circuit to specify it was verified that the developed LCD drive circuit showed good performances, such as convenience of users, low cost. |
