DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17837708 titled 'DISPLAY DEVICE

Simplified Explanation

The patent application describes a display device that includes sub-pixels, a bank, a wavelength control layer, a color filter layer, and light emitting element layers.

The display device has sub-pixels and a bank that separates them.
A wavelength control layer is placed within the bank and includes wavelength conversion layers and a light transmitting layer.
A color filter layer is placed on top of the wavelength control layer.
Light emitting element layers are positioned between the substrate and the wavelength control layer.
The light emitting element layers contain a light emitting element in one of the sub-pixels and connection electrodes connected to the ends of the light emitting element.
Each of the wavelength conversion layers makes contact with at least one of the connection electrodes.

Potential applications of this technology:

Display devices such as televisions, computer monitors, and smartphones could benefit from this technology.
The improved color accuracy and efficiency of the display could enhance the viewing experience for users.

Problems solved by this technology:

The wavelength control layer and color filter layer help to improve color accuracy and reduce color bleeding in the display.
The connection electrodes ensure proper functioning of the light emitting element.

Benefits of this technology:

Enhanced color accuracy and reduced color bleeding result in improved image quality.
The use of connection electrodes ensures reliable operation of the light emitting element.
The overall design of the display device allows for efficient and effective control of light emission.
