Abstract
The present disclosure provides a display device. The display device includes a gain provider for gradually decreasing a gain value from a first time when a first period elapses from a time at which an enable signal is generated, and a plurality of pixels for receiving data voltages determined by the gain value and the input grayscale values. The gain provider determines a length of the first period according to a first load value based on the input grayscale values at the time at which the enable signal is generated.
Claims20
A display device comprising:
- a gain provider configured to gradually decrease a gain value from a first time when a first period elapses, wherein the first period starts from a time at which an enable signal is generated to the first time;
- and
- a plurality of pixels configured to receive data voltages determined by the gain value and input grayscale values,
- wherein the gain provider determines a length of the first period according to a first load value based on the input grayscale values at the time at which the enable signal is generated.

A display device comprising:
- a plurality of pixels commonly coupled to a first power line;
- and
- a current sensor configured to provide a sensing value of a current flowing in the first power line,
- wherein the pixels gradually decreases a luminance of a still image from a first time while the still image is being displayed,
- wherein the first time is a time when a first period elapses from a time at which the display of the still image is started, and
- wherein a length of the first period is changed depending on the sensing value at the time at which the display of the still image is started.
