DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18456915 titled 'DISPLAY DEVICE

Simplified Explanation

The patent application describes a display device that includes a first base substrate with a light-emitting area and a non-light-emitting area. It also includes a wavelength conversion pattern on the base substrate in the light-emitting area and a light-emitting element layer on the pattern. The light-emitting element layer consists of a pixel electrode with a first conductive pattern between the wavelength conversion pattern and the base substrate, a second conductive pattern on the wavelength conversion pattern, an organic light-emitting layer on the second conductive pattern, and a common electrode on the organic light-emitting layer.

• The display device has a light-emitting area and a non-light-emitting area.
• A wavelength conversion pattern is placed on the light-emitting area of the base substrate.
• A light-emitting element layer is formed on the wavelength conversion pattern.
• The light-emitting element layer includes a pixel electrode with a first conductive pattern between the wavelength conversion pattern and the base substrate.
• The light-emitting element layer also includes a second conductive pattern on the wavelength conversion pattern, an organic light-emitting layer on the second conductive pattern, and a common electrode on the organic light-emitting layer.

Potential Applications

• This display device can be used in various electronic devices such as smartphones, tablets, televisions, and computer monitors.
• It can also be utilized in wearable devices like smartwatches and augmented reality glasses.

Problems Solved
