Abstract: A transparent touch display apparatus including a device substrate, a touch electrode and a routing line. The device substrate may include an emission area and a transmission area. The touch electrode may be disposed on the transmission area of the device substrate. The routing line may be disposed outside the emission area and the transmission area of the device substrate. A transmittance of the touch electrode may be higher than a transmittance of the routing line. Thus, in the transparent touch display apparatus, the reliability of the touch detection may be improved.

Abstract: A touch display apparatus senses a touch of a user, a tool or both. In the touch display apparatus, an upper electrode of a light-emitting device includes a first electrode portion overlapping an emission area, and a second electrode region spaced away from the first electrode region. A touch wire is disposed on an encapsulating element covering the light-emitting device. The touch wire includes a portion overlapping the second electrode region. Thus, in the touch display apparatus, a process of forming components for sensing the touch may be simplified.

Abstract: A touch display apparatus senses a touch of a user and/or a tool. In the touch display apparatus, an upper electrode of each light-emitting device may include a first electrode region overlapping with an emission area and a second electrode region being spaced away from the first electrode region. The second electrode region may be connected to a link wire different from the first electrode region. Thus, in the touch display apparatus, at least one of the first electrode region and the second electrode region of each upper electrode may be used for sensing the touch of the user and/or the tool. Therefore, in the touch display apparatus, a process of forming components for sensing the touch may be simplified.

Abstract: A transparent touch display apparatus includes a light-emitting device on an emission area of a device substrate and a touch electrode on a transmission area of the device substrate. The light-emitting device includes a first electrode, a light-emitting layer and a second electrode. The touch electrode includes the same material as the second electrode. An encapsulating element is disposed on the light-emitting device and the touch electrode. An over-coat layer is disposed between the device substrate and the light-emitting device, and between the device substrate and the touch electrode. A first link wire electrically connected to the second electrode of the light-emitting device and a second link wire electrically connected to the touch electrode are disposed between the device substrate and the over-coat layer.
