  • Patent number: 9214108
    Abstract: A self-luminous display apparatus, a peak luminance adjustment apparatus is disclosed wherein power to be consumed by a self-luminous display panel is compulsorily suppressed to a level within a prescribed range and consequently the life of a battery is maintained. A mean gradation value calculation section calculates a mean gradation value of a video signal inputted within a period of one frame. A power consumption calculation section determines a standard peak luminance corresponding to the calculated mean gradation value and calculates a power consumption amount to be consumed based on the standard peak luminance and the calculated mean gradation value. A peak luminance adjustment section adjusts the standard peak luminance so that a total value of the power consumption to be consumed within a fixed period of time may not exceed a preset power amount.
