Classification: CPC G  H | IPC G

Claim 0:
1. A display apparatus comprising:
a display panel that includes a plurality of pixels arranged in a matrix, each of the plurality of pixels including a self-luminous element, and that displays a video according to a video signal; and
a current limiting circuit that limits current consumption in the plurality of pixels, wherein
the current limiting circuit includes
a gain computation circuit that computes a screen power value corresponding to power consumption in the plurality of pixels in reference to a pixel value included in the 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 including the plurality of pixels, and
a lighting control circuit that controls a lighting state of the plurality of pixels in reference to a predicted power value corresponding to power predicted to be consumed in the plurality of pixels, the predicted power value being 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, and
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, when the screen power value exceeds the control target power value.
