Abstract
A touch display apparatus is provided. In the touch display apparatus, a touch structure may be disposed on an encapsulating element covering a light-emitting device. A touch insulating layer may be disposed between a touch electrode and a bridge electrode of the touch structure. The touch insulating layer may include a guide opening on a path of light emitted from the light-emitting device. A side of the guide opening may be covered by the touch electrode. Thus, in the touch display apparatus, the front luminance may be improved.
Claims16
A touch display apparatus, comprising:
- a light-emitting device on a substrate;
- an encapsulating element on the substrate, the encapsulating element at least partially covering the light-emitting device;
- a touch structure on the encapsulating element, the touch structure including touch electrodes and at least one bridge electrode electrically connecting adjacent touch electrodes;
- a touch insulating layer between the touch electrodes and the bridge electrode;
- and
- a guide opening in the touch insulating layer, wherein the guide opening overlaps the light-emitting device, and wherein a side of the guide opening is at least partially covered by one of the touch electrodes.

A touch display apparatus, comprising:
- a light-emitting device including a first emission electrode, a light-emitting layer, and a second emission electrode, which are sequentially stacked on a substrate;
- an encapsulating element on the second emission electrode of the light-emitting device;
- a touch insulating layer on the encapsulating element;
- a guide opening in the touch insulating layer, the guide opening overlapping with the light-emitting device;
- a bridge electrode between the encapsulating element and the touch insulating layer, the bridge electrode spaced apart from the guide opening of the touch insulating layer;
- and
- a touch electrode on an upper surface of the touch insulating layer opposite to the substrate, the touch electrode electrically connected to the bridge electrode,
- wherein the touch electrode extends onto a side of the guide opening.
