A 480‐output TFT‐LCD source driver IC for a COG (Chip On Glass) application is presented. To reduce the cost of the TFT‐LCD module, COG technology is being adopted for the portable display devices. To achieve the high data rate transfer on the COG‐type TFT‐LCD module, an ACDS (Advanced Current‐mode Differential Signaling) interface is proposed. The offset compensating algorithm is adopted to alleviate the block dim phenomenon due to the offset of internal gamma buffers. The driver IC was fabricated in 0.35um high voltage CMOS technology process and evaluated with 13.3‐inch diagonal wide XGA (1280RGB×800) TFT‐LCD module of which cost was reduced significantly.
