Abstract: A display device and a driving device thereof is disclosed. The driving device is coupled to a display panel. The driving device includes at least one first driver integrated circuit (IC) and at least one second driver integrated circuit (IC). The first driver integrated circuit is coupled to the display panel. The first driver integrated circuit drives the display panel and detects a first working temperature. The second driver integrated circuit is coupled to the display panel and the first driver IC. The second driver integrated circuit drives the display panel. The first driver IC stops driving the display panel and communicates with the second driver IC to stop driving the display panel when the first working temperature is substantially higher than a first given temperature.
