Electronic device, and methods of the electronic device for generating feedback related to an interaction with a touch input arrangement

1 . A method, performed by an electronic device, for generating feedback related to an interaction with a touch input arrangement, wherein the electronic device comprises:

a display comprising a display area, wherein the display area comprises a sub-display area which is smaller than the display area;

a display driver configured to control a respective one of one or more pixels of the display area including one or more pixels of the sub-display area; and

a sub-display driver configured to control the respective one of the one or more pixels of the sub-display area;

wherein the touch input arrangement is arranged outside the display area of the display,

and wherein the method comprises:

in response to a sensed proximity of an object relative to the touch input arrangement, controlling, by the sub-display driver, the one or more pixels of the sub-display area to display information related to the touch input arrangement, and

activating the sub-display area, independently of the remainder of the display area, in response to the sensed proximity of the object relative to the touch input arrangement.

2 . The method according to claim 1 , further comprising activating the touch input arrangement in response to the sensed proximity of the object relative to the touch input arrangement.

3 . The method according to claim 1 , further comprising de-activating the sub-display and/or the touch input arrangement in response to a sensed removal of the object from the proximity of the touch input arrangement.

4 . The method according to claim 1 , wherein the electronic device comprises a memory, integrated or in close proximity of the touch input arrangement, comprising the information related to the touch input arrangement and configured for use only for the sub-display area.

5 . The method according to claim 1 , wherein the touch input arrangement comprises a proximity sensor configured to sense proximity of the object relative to the touch input arrangement.

6 . The method according to claim 1 , wherein the electronic device comprises the touch input arrangement and the proximity sensor, the method further comprising sensing proximity of the object relative to the touch input arrangement with the proximity sensor.

7 . The method according to claim 1 , wherein the information related to the touch input arrangement comprises a graphical representation of the touch input arrangement and a position of the object relative to the touch input arrangement.

8 . The method according to claim 1 , wherein the display is arranged on a first surface of the electronic device and the touch input arrangement is arranged on a second surface which differs from the first surface.

9 . The method according to claim 1 , wherein the touch input arrangement is arranged on the electronic device such that it is not visible when the display is viewed.

10 . The method according to claim 1 , wherein the touch input arrangement comprises a capacitive sensor.

11 . The method according to claim 1 , wherein the touch input arrangement comprises multiple touch input arrangements, and wherein the information related to the touch input arrangement comprises information related to a first touch input arrangement out of the multiple touch input arrangements for which first touch input arrangement proximity is sensed.

12 . The method according to claim 1 , wherein the touch input arrangement and a proximity sensor configured to sense proximity of the object relative to the touch input arrangement are comprised in a second electronic device.

13 . The method according to claim 1 , wherein the touch input arrangement comprises a button.

14 . The method according to claim 1 , wherein the sub-display driver controls the one or more pixels of the sub-display area to display information related to the touch input arrangement while the display driver is off.

15 . An electronic device for generating feedback related to an interaction with a touch input arrangement, wherein the electronic device comprises:

a display comprising a display area, wherein the display area comprises a sub-display area which is smaller than the display area;

a display driver configured to control a respective one of one or more pixels of the display area including one or more pixels of the sub-display area; and

a sub-display driver configured to control the respective one of the one or more pixels of the sub-display area;

and wherein the touch input arrangement is arranged outside the display area of the display, wherein the electronic device is configured to:

in response to a sensed proximity of an object relative to the touch input arrangement, control, by the sub-display driver, the one or more pixels of the sub-display area to display information related to the touch input arrangement, and

activate the sub-display area, independently of the remainder of the display area, in response to the sensed proximity of the object relative to the touch input arrangement.

16 . The electronic device according to claim 15 , wherein the electronic device is any of a mobile phone, a tablet, a TV, a monitor, electronic eyewear, a headset, an alarm clock, a car, and a music player.

17 . A non-transitory computer readable medium having stored therein a computer program, comprising computer readable code that when, executed on an electronic device, causes the electronic device to perform a method, wherein the electronic device is for generating feedback related to an interaction with a touch input arrangement, wherein the electronic device comprises:

a display comprising a display area, wherein the display area comprises a sub-display area which is smaller than the display area;

a display driver configured to control a respective one of one or more pixels of the display area including one or more pixels of the sub-display area; and

a sub-display driver configured to control the respective one of the one or more pixels of the sub-display area;

wherein the touch input arrangement is arranged outside a display area of the display, and wherein the method comprises:

in response to a sensed proximity of an object relative to the touch input arrangement, controlling, by the sub-display driver, the one or more pixels of the sub-display area to display information related to the touch input arrangement, and

activating the sub-display area, independently of the remainder of the display area, in response to the sensed proximity of the object relative to the touch input arrangement.
