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

This abstract first appeared for US patent application 18229225 titled 'DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME

Simplified Explanation

The patent application describes a display device with a circuit layer and a display element layer, which includes a light-emitting element and a pixel-defining film.

• The display element layer has a pixel opening defined by the pixel-defining film.
• The light-emitting element includes a first electrode exposed through the pixel opening, a second electrode opposite to the first electrode, and a light-emitting layer between them.
• The first electrode consists of a metal layer and a graphene layer on top, both with a hexagonal closed packed structure.

• • Potential Applications:**

• Consumer electronics such as smartphones, tablets, and TVs.
• Automotive displays.
• Wearable technology like smartwatches and fitness trackers.

• • Problems Solved:**

• Improved display quality and efficiency.
• Enhanced durability and longevity of the display device.
• Reduction in power consumption.

• • Benefits:**

• Higher resolution and brightness in displays.
• Thinner and lighter display devices.
• Increased energy efficiency and longer battery life.

Original Abstract Submitted

A display device includes a circuit layer and a display element layer on the circuit layer. The display element layer includes a light-emitting element and a pixel-defining film, through which a pixel opening is defined, and the light-emitting element includes a first electrode exposed through the pixel opening, a second electrode disposed opposite to the first electrode, and a light-emitting layer disposed between the first electrode and the second electrode. The first electrode includes a metal layer and a graphene layer disposed on an upper surface of the metal layer, and the metal layer and the graphene layer each have a hexagonal closed packed structure.
