Abstract

This electronic device comprises: a window comprising a first region; a display panel comprising a first opening; an adhesive member comprising an adhesive material and comprising a second opening; an opaque member comprising an opaque material disposed along the boundary of the first region; a sensor disposed under the window and visible through the first and second openings; and a display driving circuit configured to activate some first pixels among the pixels of the display panel disposed in a region where the display panel overlaps the opaque member.

First claim

What is claimed is:

1. An electronic device comprising:
a window comprising a first region;
a display panel facing one surface of the window, and comprising a first opening;
an adhesive member comprising an adhesive material interposed between the window and the display panel, and comprising a second opening;
an opaque member comprising an opaque material disposed along a periphery of the first region when viewed from above the window;
a sensor disposed under the window and at least partially visible through the first opening and the second opening; and
a display driving circuit operably coupled with the display panel,
wherein the display driving circuit is configured to activate some first pixels among the pixels of the display panel disposed in a region where the display panel overlaps the opaque member when viewed from above the window.

2. The electronic device of claim 1 , wherein remaining second pixels other that the first pixels are configured to be inactivated while the first pixels are activated.

3. The electronic device of claim 2 , wherein the first pixels are disposed substantially surrounding the second pixels.

4. The electronic device of claim 3 , wherein the display driving circuit is configured to activate the first pixels to display a gradation effect.

5. The electronic device of claim 4 , wherein the first pixels display the gradation effect together with third pixels among other pixels of the display panel that surround the opaque member when viewed from above the window.

6. The electronic device of claim 5 , wherein the third pixels of the other pixels are located within a specified distance from the center of the first region.

7. The electronic device of claim 6 , wherein fourth pixels other than the third pixels among the other pixels display a screen independent of the gradation effect.

8. The electronic device of claim 1 , wherein a size of the second opening is less than a size of the first opening.

9. The electronic device of claim 1 , wherein the sensor comprises at least one of a sensor configured to emit light towards an outside of the electronic device, a sensor configured to receive light from the outside, a sensor configured to output a sound towards the outside, or a sensor configured to receive a sound from the outside.

10. The electronic device of claim 1 , wherein the adhesive material of the adhesive member comprises an optical clear adhesive (OCA).

11. The electronic device of claim 1 , wherein the opaque member is interposed between the window and the display panel to hide a wire for driving the display panel.

12. The electronic device of claim 11 , wherein the opaque material of the opaque member comprises an opaque resin or an opaque ink.

13. The electronic device of claim 1 , further comprising a transparent touch panel interposed between the window and the adhesive member,
wherein the opaque member is interposed between the touch panel and the window.

14. The electronic device of claim 13 , wherein touch patterns of the touch panel disposed over some of the pixels are inactivated while some first pixels among the pixels are activated.

15. The electronic device of claim 1 , further comprising a support disposed opposite the window of the display panel, the support comprising a third opening, and supporting at least one of the display panel, the adhesive member, or the opaque member.

16. An electronic device comprising:
a window comprising a first region;
a display panel facing one surface of the window, and comprising a first opening;
an adhesive member comprising an adhesive material interposed between the window and the display panel, and comprising a second opening;
an opaque member comprising an opaque material disposed along a periphery of the first region when viewed from above the window;
a sensor disposed under the window and at least partially visible through the first opening and the second opening; and
a display driving circuit operably coupled with the display panel,
wherein the display driving circuit is configured to:
activate at least one pixel disposed within a projection of the opaque member when viewed from above the window among pixels of the display panel, and
inactivate at least one other pixel disposed outside the projection of the opaque member when viewed from above the window among the pixels, based on an image of a second region of the display panel having a shape corresponding to an outer periphery of the opaque member and partially overlapping the opaque member when viewed from above, in a state of vertically facing another surface of the window.

17. The electronic device of claim 16 , wherein the image can include a vector image.

18. The electronic device of claim 16 , wherein the electronic device can further include a memory external to the display driving circuit configured to store the image.

19. The electronic device of claim 16 , wherein the electronic device can further include a memory within the display driving circuit configured to store the image.

20. The electronic device of claim 16 , wherein the display driving circuit can be configured to activate the at least one pixel and inactivate the at least one another pixel based on synthesizing the image and an image of a screen to be displayed.
