Abstract:
1. A self light emission display device comprising: a buffer memory configured to delay the supply of pixel data to a self light emission panel; a lookup table configured to store all gradation values corresponding to a variable range of the pixel data and electric power values to be consumed for light emission respectively at the gradation values, in association with each other; a power consumption calculator configured to add respective power consumption values of all pixels of a frame which are determined by referring to said lookup table to calculate a power consumption value of the frame; and a power consumption transition recognizer configured to generate information representative of a transition of the power consumption value of the frame, wherein said information representative of the transition of the power consumption value of the frame includes the power consumption value, a rate of change of the power consumption value, an average power consumption value, and a total power consumption value.
