CURRENT LIMITING CIRCUIT, DISPLAY DEVICE, AND CURRENT LIMITING METHOD
Abstract:
A current limiting circuit includes: a delay circuit that receives a video signal, and outputs a delay signal obtained by delaying the video signal by a time period corresponding to one frame; a calculation circuit that receives the video signal, and calculates a gain by which the delay signal is to be multiplied, based on power consumption of the pixels corresponding to the delay signal and power consumption of the pixels corresponding to the video signal; and a gain multiplication circuit that multiplies the delay signal by the gain.
