Abstract
A display device including a display unit including a plurality of light emitting elements, and a control unit that individually controls the plurality of light emitting elements in each of a plurality of main frames according to the gradation data externally input based on output from an external device. The plurality of main frames each include a plurality of sub-frames. The control unit turns on predetermined ones of the plurality of light emitting elements in a predetermined one of the plurality of main frames such that a difference between a gradation value of one or more of the plurality of sub-frames having a maximum gradation value and a gradation value of one or more of the plurality of sub-frames having a minimum gradation value is at least 2.
Claims17
A display device comprising:
- a display unit including a plurality of light emitting elements:
- and
- a control unit that individually controls the plurality of light emitting elements in each of a plurality of main frames according to gradation data externally input based on output from an external device, wherein
- the plurality of main frames each include a plurality of sub-frames of equal duration,
- the control unit is configured to apply, by pulse width modulation, voltage to predetermined ones of the plurality of light emitting elements in a predetermined one of the plurality of main frames such that a difference, with respect to the predetermined main frame, between a maximum gradation value and a minimum gradation value is at least 2, the gradation value being defined per sub-frame and corresponding to a pulse width of the voltage, and
- the longer the pulse width, the higher the gradation value becomes.
