Disclosed is a correction method executed by a control unit (20) in an organic EL display (10) including a volatile memory (MV) which stores a cumulative value, a nonvolatile memory (MNV) having a slower writing speed than the volatile memory (MV), and said control unit (20), the method comprising: executing a cumulation process in which the cumulative value of the volatile memory (MV) is repeatedly updated every first period; executing a transfer process in which the cumulative value is transferred from the volatile memory (MV) to the nonvolatile memory (MNV) every second period which is longer than the first period; and delaying the timing of the transfer process for a portion of display pixels in accordance with the writing speed of a second memory and delaying the timing for starting the cumulation process for the portion of display pixels in accordance with the timing of the transfer process, or switching the order for transferring the cumulative value in the transfer process between a first order and a second order which is the reverse of the first order. |
