1. A display system comprising:
a host processor including a first thermal sensor, wherein a plurality of transistors of the host processor are integrated with the first thermal sensor at a same semiconductor substrate, and the first thermal sensor generates first temperature information; and
a display driver integrated circuit including a display interface and a second thermal sensor that is different from the first thermal sensor, wherein the second thermal sensor generates second temperature information and outputs the second temperature information via the display interface,
wherein the host processor is configured to:
receive the second temperature information from the display interface of the display driver integrated circuit; and
generate 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 the second temperature information that is obtained from the display driver integrated circuit, and to output the first performance control signal,
wherein the display driver integrated circuit is configured to receive the first performance control signal from the host processor, and to control the display panel based on the first performance control signal to adjust the performance of the display panel,
wherein the host processor is configured:
to determine, based on the first temperature information, a first duration for which the display driver integrated circuit and the display panel are set to operate with a first performance,
to determine, based on the second temperature information, a second duration for which the display driver integrated circuit and the display panel are set to operate the first performance,
to select the first duration when the first duration is shorter than the second duration, and
to set the first performance control signal based on the first duration such that the display driver integrated circuit and the display panel operate with the first performance for the first duration.
