Problems solved by technology

[0003] If the transparency of the transparent display device is too low, the user will obviously observe the existence of the display device itself, but cannot clearly observe the background behind the display device
In addition, if the transparent display device is to have a touch sensing function, the transparency of the transparent display device is likely to be deteriorated due to the arrangement of electrodes and wiring for touch sensing.
There is still much room for improvement in transparent display devices

Abstract

The invention relates to a transparent display device comprising a substrate, a light-emitting element, a first barrier wall structure, a first top conductive pattern and a barrier encapsulation multilayer structure. The substrate has a light-emitting area and a light-transmitting area. The light emitting element is located in the light emitting area. The first retaining wall structure has undercut sidewalls. The first barrier structure is the junction of the light-transmitting area and the light-emitting area, and the light-emitting element is located in the light-emitting area surrounded by the first barrier structure. The first top conductive pattern is configured on the top surface of the first retaining wall structure. The barrier encapsulation multilayer structure is configured on the light emitting element. The barrier encapsulation multilayer structure includes a first barrier layer and a second barrier layer. A portion where the first barrier layer and the second barrier layer overlap each other is located in the light emitting area surrounded by the first retaining wall structure.

Description

technical field [0001] The invention relates to a transparent display device. Background technique [0002] The transparent display device itself has a certain degree of transparency, which can not only display information or pictures, but also allow users to clearly see the background behind the display. Transparent display devices can be used in various applications such as building windows, automobile windows, and shop windows, and thus attract market attention. [0003] If the transparency of the transparent display device is too low, the user will obviously observe the existence of the display device itself, but cannot clearly observe the background behind the display device. In addition, if the transparent display device is to have a touch sensing function, the transparency of the transparent display device will be easily deteriorated due to the arrangement of electrodes and wires for touch sensing. There is still much room for improvement in transparent display devi...
