Display-Mainly from IDW/AD '05-a-Si Gate Driver Designs for Low Power AMLCD Operation

We have developed two 1.8" QVGA (222dpi) transflective a-Si AMLCDs with integrated gate drivers. One is optimized for a very low power normal operating mode. The other can switch to an arbitrary partial scan mode. Gate driver integration results in narrow, symmetric margins, reduced cost, and fewer interconnections. Also, we minimized the number of connections to the display while retaining some to achieve very significant power reduction.
