Display apparatus

Abstract

A display apparatus includes an RGB-RGBX signal converter configured to convert digital R, G, and B input signals into digital R, G, B, and X input signals. A D/A converter is configured to convert the digital R, G, B, and X input signals into analog R, G, B, and X output signals. An RGBX type self light-emitting display is configured to receive the analog R, G, B, and X output signals. A calculator is configured to calculate an accumulated power consumption value of the self light-emitting display for each screcn, based on the digital R, G, B, and X input signals. A controller is configured to control amplitudes of the respective analog R, G, B, and X input signals by controlling a reference voltage supplied to the D/A converter based on the accumulated power consumption value, and to supply the respective amplitudeaontrolled analog R, G, B, and X input signals to the self light-emitting display.
