Patent ID: 11893932

Abstract:
A display apparatus includes a display panel including a plurality of pixels, and a current limiting circuit that limits current consumption in the plurality of pixels, the current limiting circuit includes a gain computation circuit that computes a screen power value in reference to a pixel value included in a video signal and that determines a gain in reference to the screen power value, and a gain multiplication circuit that multiplies the pixel value by the gain and that outputs a limit signal including the pixel value multiplied by the gain, the display panel includes a display unit, and a lighting control circuit that controls a lighting state of the plurality of pixels in reference to a predicted power value computed according to the limit signal, to reduce a power consumption value in the plurality of pixels to a value equal to or smaller than a control target power value, the gain is 1 when the screen power value is equal to or smaller than the control target power value, and the gain is a value equal to or smaller than a value obtained by dividing the control target power value by the screen power value, in other cases.
