Abstract:
A control device includes a data storing unit, a synchronization control unit, a light emission control unit, and a luminance adjustment unit. The light emission control unit derives a luminance adjustment parameter for adjusting a light emission luminance of light emitting elements when a video image is displayed with a total number of vertical lines in a current frame such that a total light emission amount of the light emitting elements during one frame period when the video image is displayed with the total number of vertical lines in the current frame is equal to a total light emission amount of the light emitting elements during one frame period when a video image is displayed with a pre-set minimum number of vertical lines. The luminance adjustment unit adjusts, based on the luminance adjustment parameter, the light emission luminance of the light emitting elements.

Claim (Index 11):
A method for driving a display panel in which a plurality of pixel circuits that include light emitting elements are arranged in rows and columns, the method comprising:\n starting a frame period when a vertical synchronization signal is received or a start timing of a video image signal is detected, the frame period including a video image period and an extended period, the video image period being a period from after start of the frame period to end of supply of the video image signal to the pixel circuits, and the extended period being a period from after end of the video image period to next reception of the vertical synchronization signal or next detection of the start timing of the video image signal; deriving, by a light emission control unit, a luminance adjustment parameter based on a total number of vertical lines in a current frame notified after the reception of the vertical synchronization signal or detection of a start timing of a video image signal, the luminance adjustment parameter being a parameter for adjusting a light emission luminance of the light emitting elements when a video image is displayed with the total number of vertical lines in the current frame; initializing the pixel circuits within a predetermined period after the reception of the vertical synchronization signal or the detection of the start timing of the video image signal; temporarily storing the video image signal in a data storing unit after the reception of the vertical synchronization signal or the detection of the start timing of the video image signal; adjusting, by a luminance adjustment unit, the light emission luminance of the light emitting elements by performing calculation using the video image signal read out from the data storing unit and the luminance adjustment parameter; and after the initializing of the pixel circuits and during the video image period, causing the light emitting elements to emit light at the adjusted light emission luminance to display the video image signal, wherein in the deriving of the luminance adjustment parameter, the luminance adjustment parameter is derived such that a total light emission amount of the light emitting elements during one frame period when the video image is displayed with the total number of vertical lines in the current frame is equal to a total light emission amount of the light emitting elements during one frame period when a video image is displayed with a pre-set minimum number of vertical lines.
