[Problem] To provide a life prediction method and device that can predict the life of a display device considering the differences between temperatures at measurements of the luminance of the display device. [Solving Means] A monitor 1 measures the luminance of the display screen using an optical sensor 19 and measures the temperature around the display screen using a temperature sensor 20. A terminal device 3 stores the measured luminances and temperatures in such a manner that the luminance and temperature are associated with each other. On the basis of the measured luminances and temperatures obtained by repeated measurements, the terminal device 3 predicts the trend of changes in the luminance assuming that the temperatures at the measurements have been approximately constant, and predicts the life of the monitor 1 on the basis of the predicted change trend. The terminal device 3 calculates the time when the luminance of the monitor 1 will fall below the critical luminance, on the basis of the predicted luminance change trend and regards this time as the time when the life of the monitor 1 will be reached. |
