Abstract
The present invention relates to a backlight image sensor chip having improved chip driving performance, in which a region other than a pad region, on which a conductive pad is formed, and a sensing region, on which an optical filter is formed, is used as a region for auxiliary driving so that additional functions such as auxiliary power supply, auxiliary signal transmission and auxiliary operation control can be performed, without additional process, in the backlight image sensor chip having a restricted area, thereby improving the chip driving performance.
