Abstract: The present invention includes a device for controlling rolling shutter timing, the device including: a first Gate-On-Array (GOA) driving unit configured to generate a reset signal for resetting an image sensor in a unit of a gate line; a second GOA driving unit configured to generate a scan signal for scanning the image sensor in the unit of the gate line; and a timing controller configured to control generation timing of the reset signal and the scan signal. According to the device and the method of controlling rolling shutter timing based on GOA, it is possible to satisfy a bezel-less edge level of a display panel of a smart phone, expand a fingerprint recognition area to a large area by rapidly reading a fingerprint location area, freely control an exposure time, and reduce occurrence of a delay time.
