  • Publication number: 20220208862
    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.
