  • Patent number: 11755141
    Abstract: A display device includes: a display panel configured to display an image; an input sensor on the display panel and configured to operate in a first sensing mode or a second sensing mode different from the first sensing mode; and a sensor controller configured to drive the input sensor, wherein the sensor controller is configured to drive the input sensor under a first driving condition different from a driving condition of the first sensing mode in response to the second sensing mode being entered, and the sensor controller is configured to change the first driving condition to a second driving condition different from the first driving condition according to a specific event which occurs after entering the second sensing mode.

  • Publication number: 20160216828
    Abstract: An image display terminal and a method of controlling a touch for an image display terminal are disclosed. In one aspect, the method includes displaying a first widget in a first area on a touch screen and a second widget in a second area on the touch screen different from the first area. The method also includes extracting a first touch policy of the first widget and a second touch policy of the second widget. The method further includes individually controlling touch driving characteristics of the first and second areas based on the first and second touch policies.

  • Publication number: 20150187338
    Abstract: A display device including a display unit configured to output a base image; a curvature sensing unit configured to sense one of a forward folded state and a reverse folded state of the display unit; and an interface control unit configured to generate an interface image. The interface image may include a forward folded interface image corresponding to the forward folded state of the display unit, or a reverse folded interface image corresponding to the reverse folded state of the display unit. The interface control unit is configured to overlay the interface image on a base image and output the overlaid image.
