摘要： A signal processing device measures an actual luminance of a pixel circuit having a light-emitting device every update period by setting levels of gradation values. A conversion efficiency value is calculated for the light-emitting device to convert a driving current supplied in accordance with a gradation value into a luminance based on the luminance value and a gradation value corresponding to the luminance value. A driving current corresponding to the luminance value is calculated, and a comparison is made of the relationship between the driving current and a gradation value corresponding to the luminance value with the relationship between a driving current and a gradation value when the pixel circuit is in a correction reference state. This is used to calculate a current amount deterioration value of a driving current of the pixel circuit, and generates current amount deterioration characteristic information of the pixel circuit.
