Abstract

Suppresses flicker. [Solution] The display device 100 comprises a display unit 3 on which multiple light-emitting elements are arranged, and a control unit 2 for controlling the lighting of each light-emitting element based on display data input at a predetermined display update cycle. When the control unit 2 performs subframe modulation, which divides a frame, which is a display unit corresponding to the display data, into multiple subframes for display, it allocates multiple subframes and multiple periods of no illumination within one display update cycle. Each period of no illumination is shorter than one subframe and is divided and arranged to have a constant period of no illumination TN1.

Claims

1. A display unit with multiple light-emitting elements, A control unit for controlling the illumination of each light-emitting element based on display data input at a predetermined display update cycle, A display device comprising, When the control unit performs subframe modulation, which divides a frame, which is a display unit corresponding to the display data, into multiple subframes for display, within one display update cycle, Multiple subframes, Multiple periods of non-illumination, Assign, A display device configured such that each non-illumination period is shorter than one subframe and is divided and arranged to form a constant non-illumination cycle.

2. A display device according to claim 1, The control unit is a display device that provides the non-illumination period for each frame.

3. A display device according to claim 1, The control unit is a display device that provides the non-illumination period for each subframe.

4. A display device according to claim 1, The control unit controls the illumination of the display unit using dynamic scanning, and the display device is configured to have a non-illumination period for each scan of the scanning line.

5. A display device according to any one of claims 1 to 4, The control unit controls the illumination of the display device so that each non-illumination period is added after the scan of each frame, each subframe, or each scan line.

6. A lighting control circuit for a display device, connected to a display unit having multiple light-emitting elements, for controlling the lighting of each light-emitting element based on display data input at a predetermined display update cycle, When performing subframe modulation, which divides a single frame (the display unit corresponding to the displayed data) into multiple subframes for display, within one display update cycle, Multiple subframes, Multiple periods of non-illumination, Assign, A lighting control circuit for a display device, wherein each non-illumination period is shorter than one subframe and is configured to be divided and arranged to form a constant non-illumination cycle.

7. A display unit with multiple light-emitting elements, A control unit for controlling the illumination of each light-emitting element based on display data input at a predetermined display update cycle, A method for controlling the illumination of a display device, comprising: The control unit performs subframe modulation, dividing a frame, which is a display unit corresponding to the display data, into multiple subframes for display, and within one display update cycle, it divides and arranges multiple subframes and multiple blackout periods such that each blackout period is shorter than one subframe, resulting in a constant blackout cycle. When new display data is input from an external source at the display update cycle, the control unit performs subframe modulation on the new display data and repeats the process of dividing and arranging multiple periods of no illumination within one display update cycle. A method for controlling the illumination of a display device, including the display device itself.
