Abstract
Official abstract text for this publication.
Provided is a display device. The display device includes a display panel including a folding area and non-folding areas on both sides of the folding area. The display device also includes a support substrate disposed under the display panel. The support substrate includes a plurality of openings disposed in the folding area, and a plurality of press structures disposed in the non-folding areas. Therefore, it is possible to implement a display device that provides a tactile feedback for each touch input area.
First claim
Opening claim text (preview).
What is claimed is: 1. A display device, comprising: a display panel including a folding area and non-folding areas on both sides of the folding area; and a support substrate disposed under the display panel, wherein the support substrate includes: a plurality of press structures disposed in the non-folding areas, wherein each of the plurality of press structures includes: a planar portion to be moved down when a touch pressure is applied; and a hole surrounding a part of the planar portion and forming elasticity to restore to the planar portion original state when the touch pressure is removed. 2. The display device according to claim 1 , wherein the hole has a spiral shape surrounding the planar portion. 3. The display device according to claim 1 , wherein the hole includes a zigzag shape. 4. The display device according to claim 1 , further comprising: a touch panel configured to receive a user's touch input; and an actuator disposed under the support substrate, wherein the actuator transfers a tactile feedback in response to the user's touch input. 5. The display device according to claim 4 , wherein the actuator includes: an electroactive layer; a first electrode disposed under the electroactive layer; and a plurality of second electrodes disposed on the electroactive layer and under the plurality of press structures. 6. The display device according to claim 1 , further comprising: a spacer disposed under the support substrate; an electroactive layer disposed under the spacer; and a first electrode disposed under the electroactive layer. 7. The display device according to claim 6 , wherein the plurality of press structures, the electroactive layer and the first electrode constitute an actuator.
