QGVA급 LCD Driver IC의 Source Driver부 설계

In this paper. we design a source driver block for QVGA (240RGB*320)-scale LCD Driver IC (LDI) avaliable 262k-color for display. The source driver block is designed using a channeled amplifier scheme in which an unit-gain amplifier is drived to channel and γ-correction is executed to improve image view. The block consists of source drivers block, reference voltage generator block and grayscale voltage generator block. A circuit for the source driver block has been designed in transistor level using 0.35㎛ CMOS technology library and verified using Hspice.
