DISPLAY DEVICE AND METHOD OF FABRICATING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18238550 titled 'DISPLAY DEVICE AND METHOD OF FABRICATING THE SAME

Simplified Explanation

The patent application describes a display device with a unique structure involving multiple layers and openings to allow for the connection of various electrodes and power lines. Here are the key points of the innovation:

• Data conductive layer with a first power line, passivation layer, via layer, pixel electrode, connection electrode, pixel-defining film, light-emitting layer, and common electrode.
• Data conductive layer consists of a data base layer, data main metal layer, and data capping layer.
• First power line includes a wire connection structure where the data main metal layer is recessed from the sides of the data capping layer.
• Common electrode is connected to the data main metal layer in the wire connection structure.

Potential Applications

The technology described in this patent application could be applied in various display devices such as smartphones, tablets, TVs, and monitors.

Problems Solved

This technology solves the problem of efficiently connecting different electrodes and power lines in a display device while maintaining a compact and reliable structure.

Benefits

The benefits of this technology include improved display performance, increased durability, and potentially lower production costs due to the optimized structure.

Potential Commercial Applications

The technology could be commercialized by display manufacturers looking to enhance the performance and reliability of their products.

Possible Prior Art

One possible prior art for this technology could be similar display devices with complex electrode and power line structures, but without the specific wire connection structure described in this patent application.

How does this technology compare to existing display device structures in terms of efficiency and reliability?

This article does not provide a direct comparison with existing display device structures, so it is unclear how this technology stands out in terms of efficiency and reliability.

What are the potential challenges in implementing this technology on a large scale for commercial production?

The article does not address the potential challenges in scaling up this technology for commercial production, leaving room for speculation on the practicality and feasibility of mass production.

Original Abstract Submitted

A display device includes a data conductive layer including a first power line, a passivation layer with a first opening exposing the first power line, a via layer with a second opening partially overlapping the first opening, a pixel electrode on the via layer, a connection electrode in the first and second openings, a pixel-defining film with an opening overlapping the second opening, a light-emitting layer on the pixel-defining film, the pixel electrode and the connection electrode, and a common electrode connected to the first power line. The data conductive layer includes a data base layer, a data main metal layer, and a data capping layer, the first power line includes a wire connection structure, in which the data main metal layer is recessed from sides of the data capping layer, and the common electrode is connected to the data main metal layer in the wire connection structure.
