DISPLAY APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18076197 titled 'DISPLAY APPARATUS

Simplified Explanation

The patent application describes a display apparatus that includes a first pixel electrode, an emission layer, and an opposite electrode. It also includes a second substrate with a bank and a first quantum dot layer. The first substrate and the second substrate are bonded together using a bonding member.

• A display apparatus with improved pixel structure and color emission capabilities is disclosed.
• The apparatus includes a first pixel electrode, an emission layer, and an opposite electrode.
• A second substrate is used, with a bank and a first quantum dot layer, to enhance the display performance.
• The first substrate and the second substrate are bonded together using a bonding member.

Potential Applications

This technology can be applied in various display devices, such as:

• Televisions
• Computer monitors
• Mobile devices
• Virtual reality headsets

Problems Solved

The display apparatus addresses the following problems:

• Limited color emission capabilities of traditional display devices
• Inefficient light emission and color reproduction
• Complex pixel structures and manufacturing processes

Benefits

The display apparatus offers the following benefits:

• Improved color emission in a specific wavelength band
• Enhanced light emission efficiency and color reproduction
• Simplified pixel structure and manufacturing process

Original Abstract Submitted

A display apparatus includes: a first pixel electrode in a display area; a pixel defining layer with a first pixel opening defined in the pixel defining layer exposing a center of the first pixel electrode; an emission layer over the first pixel electrode and configured to emit light in a first wavelength band; an opposite electrode over the emission layer; a second substrate over the first substrate such that the opposite electrode is between the first substrate and the second substrate; a bank over a bottom surface of the second substrate in a direction to the first substrate, a first opening defined in the bank overlapping with the first pixel opening and a first additional opening defined in the bank overlapping with the peripheral area, a first quantum dot layer in the first opening; and a bonding member bonding the first substrate and the second substrate to each other.
