Abstract
A current limiting circuit is a circuit that receives a video signal for a display panel including pixels, and limits current consumption of the pixels. The current limiting circuit includes: a first gain calculation circuit that calculates a first gain for multiplying with the video signal, based on first power consumption that is power consumption of the pixels corresponding to the video signal; a second gain calculation circuit that calculates a second gain for multiplying with the video signal, based on the first power consumption and a rate of change of the first power consumption; a gain selection circuit that selects one of the first gain and the second gain as a gain by which the video signal is to be multiplied; and a gain multiplication circuit that multiplies the video signal by the gain.
