Abstract: A display system including a host processor and a display driver integrated circuit may be provided. The host processor may generate a clock signal that swings swinging between a high level and a low level, generate and output a first synchronization signal based on the clock signal, generate a wakeup interrupt by measuring a frame update period of a display panel, generates frame data based on the first synchronization signal by enabling an image providing path based on the wakeup interrupt, and output the frame data for every frame update period. The display driver integrated circuit may receive the first synchronization signal and the frame data from the host processor, and control the display panel such that a frame image corresponding to the frame data is displayed on the display panel based on the first synchronization signal without storing the frame data.

Abstract: A display system includes a host processor and a display driver integrated circuit. The host processor includes a first thermal sensor. The display driver integrated circuit including a second thermal sensor that is different from the first thermal sensor. The host processor generates a first performance control signal indicating whether to increase or decrease performance of a display panel from first temperature information that is obtained from the first thermal sensor and second temperature information that is obtained from the second thermal sensor, and to output the first performance control signal. The display driver integrated circuit receives the first performance control signal from the host processor, and controls the display panel based on the first performance control signal to adjust the performance of the display panel.
