Abstract
A unit equivalent value acquiring unit acquires a normal-temperature unit equivalent use time Δtn by using a temperature sensor, first to third LUTs, and a first multiplying unit. An integration unit acquires an equivalent cumulative use time to by integrating the normal-temperature unit equivalent use time Δtn. A maximum value detecting unit detects a maximum equivalent cumulative use time tnmax. A dividing unit acquires a correction coefficient Kcmp by dividing total degradation E(tnmax,Tn) acquired by a fourth LUT by total degradation E(tn,Tn) acquired by a fifth LUT. Accordingly, there is provided a data processing device for a display device capable of preventing burn-in while suppressing time degradation of an electro-optical element and increase in the number of wires.
