ABSTRACT:
It is an object to provide a timing controller and an image display device which are capable of recognizing the resolution of a display panel with a simple structure. Image signal line driving devices include integrated plural driving circuits which are connected to one another in a cascade manner. Further, the image signal line driving devices are also connected to one another in a cascade manner. A timing controller transmits a horizontal start pulse to the image signal line driving device, then receives the returned horizontal start pulse returned thereto after being circulated through the driving circuits included in the image signal line driving devices and determines the resolution (the number of pixels) in the horizontal direction of the liquid crystal display panel based on the interval between the transmission and the reception of the start pulse.
