Abstract
A display device includes a plurality of light emitting devices included in a pixel, and a control circuit configured to define each of a plurality of subframe periods included in a frame period during which a frame image is displayed as one of an emission period in which the light emitting device is in an emission state and a non-emission period in which the light emitting device is in a non-emission state, and to control emission of the light emitting device, based on a gradation value of the pixel.
Claims15
A display device comprising:
- a plurality of light emitting devices included in a pixel;
- and
- a control circuit configured to define each of a plurality of subframe periods included in a frame period during which a frame image is displayed as one of an emission period in which the light emitting device is in an emission state and a non-emission period in which the light emitting device is in a non-emission state, and to control emission of the light emitting device, based on a gradation value of the pixel, wherein
- the subframe periods are consecutively lined up from a beginning of the frame period, and
- in a case where the gradation value of the pixel corresponds to a first eliminated gradation value corresponding to the frame period that has the subframe period that is the non-emission period on a beginning side of the subframe period that is the emission period in a given subframe period set in advance and the subsequent subframe periods among the subframe periods, the control circuit modifies the gradation value of the pixel to a specific gradation value corresponding to the frame period during which the given subframe period is the emission period and the subframe periods that are the emission periods are consecutively lined up.

- the subframe periods are consecutively lined up from a beginning of the frame period, and
- in a case where the gradation value of the pixel corresponds to a gradation value corresponding to the frame period that has the subframe period that is the non-emission period between two of the subframe periods that are the emission periods, the control circuit modifies the gradation value of the pixel to a gradation value corresponding to the frame period during which the subframe periods that are the emission periods are consecutively lined up.
