Abstract
A display device according to an embodiment of the disclosure may comprise a display panel displaying an input image on a screen, a user gaze determiner determining a user gaze on the display panel based on a sensor value obtained from a motion sensor, an area divider dividing the display panel into the user's main field-of-view area, peripheral field-of-view area, and outer area based on the determined user gaze, a scan time determiner determining scan times of scan signals corresponding to the main field-of-view area and the peripheral field-of-view area, and a data driver applying a data voltage to the display panel according to the determined scan time.
Claims19
A display device, comprising:
- a display panel configured to display an input image on a screen;
- a user gaze determiner configured to determine a user gaze on the display panel based on a sensor value obtained from a motion sensor;
- an area divider configured to divide the display panel into a main field-of-view area and a peripheral field-of-view area based on the determined user gaze;
- a scan time determiner configured to determine a scan time of a scan signal corresponding to the main field-of-view area and a scan time of a scan signal corresponding to the peripheral field-of-view area;
- and
- a data driver configured to apply a data voltage to the display panel according to the determined scan time,
- wherein a width of a turn-on level of the scan signal corresponding to the main field-of-view area is different from a width of a turn-on level of the scan signal corresponding to the peripheral field-of-view area,
- wherein in response to it is determined by the user gaze determiner that the user gaze is fixed for a threshold time or more, the scan time determiner is configured to determine scan signals to have a same scan time for the entire display panel.
An image display method, comprising:
- receiving a sensor value of a user movement detected by a motion sensor;
- determining a user gaze on a display panel based on the sensor value;
- dividing the display panel into a main field-of-view area and a peripheral field-of-view area based on the determined user gaze;
- determining a scan time of a scan signal corresponding to the main field-of-view area and a scan time of a scan signal corresponding the peripheral field-of-view area;
- and
- applying a data voltage to the display panel according to the determined scan time,
- wherein in response to it is determined that the user gaze is fixed for a threshold time or more, scan signals are configured to have a same scan time for the entire display panel.
A display device, comprising:
- a display panel including a plurality of sub-pixels;
- a motion sensor configured to determine a movement of a user with respect to the display panel;
- a controller communicatively coupled to the motion sensor, the controller configured to:
- determine a user gaze at the display panel based on movement information of the user detected by the motion sensor;
- and
- divide the display panel into a main field-of-view area and a peripheral field-of-view area based on the determined user gaze,
- wherein the main field-of-view area in which at least one first sub-pixel among the plurality of sub-pixels is disposed is configured to have a first luminance level and the peripheral field-of-view area in which at least one second sub-pixel among the plurality of sub-pixels is disposed is configured to have a second luminance level different from the first luminance level, and
- wherein a first scan pulse width corresponding to the at least one first sub-pixel in the main field-of-view area is different from a second scan pulse width corresponding to the at least one second sub-pixel in the peripheral field-of-view area.
