Abstract
A display device includes a pixel array, a driver configured to drive the pixel array, and a controller configured to control the driver. The controller controls the driver such that each unit frame period is formed by a plurality of sub-frame periods, and a duty ratio in each sub-frame period is controlled. The controller controls the driver such that in each unit frame, the duty ratio of a last sub-frame period is smaller than the duty ratio of a first sub-frame period.
Claims10
A display device comprising:
- a pixel array;
- a driver configured to drive the pixel array;
- and
- a controller configured to control the driver,
- wherein the controller controls the driver such that each unit frame period is formed by a plurality of sub-frame periods, and a duty ratio in each sub-frame period is controlled,
- wherein the controller controls the driver such that each sub-frame period is formed by a first non-light-emitting period, a light-emitting period, and a second non-light-emitting period,
- wherein the first non-light-emitting period starts at a start of each sub-frame period, the light-emitting period starts at an end of the first non-light-emitting period, and the second non-light-emitting period starts at the end of the light-emitting period, and
- wherein when lengths of the first non-light-emitting period, the light-emitting period, and the second non-light-emitting period in a kth (k is 1 to n) sub-frame are defined as tDk,1, tLk, and tDk,2, respectively, the controller controls the driver to satisfy
