Abstract
Disclosed are a timing controller and an OLED display device using the same. The timing controller includes a reception unit, an image signal generation unit, and a control signal generation unit. The reception unit receives a plurality of video signals and a timing signal which are transferred from a system. The image signal generation unit realigns the video signals to generate a plurality of image signals. The control signal generation unit analyzes the video signals to determine whether a current input image is a static image or a moving image, and generates a plurality of control signals according to the determined result. When the current input image is determined as the static image, the control signal generation unit generates a plurality of control signals which allow a panel to be driven at a change frame driving frequency lower than a reference frame driving frequency necessary for driving the moving image.
