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

This abstract first appeared for US patent application 20240099074 titled 'DISPLAY DEVICE AND METHOD OF PROVIDING THE SAME

Simplified Explanation

The display device described in the patent application includes a structure with multiple layers that control the emission of light of different colors. The layers include a bank layer, a wavelength control pattern, a capping layer, and a color absorbing layer. The capping layer covers the wavelength control pattern and the bank layer, while the color absorbing layer blocks light of specific colors.

• First display substrate with light emitting element emitting light of different colors
• Second display substrate with bank layer, wavelength control pattern, capping layer, and color absorbing layer
• Capping layer includes area corresponding to color absorbing layer
• Bank layer includes area corresponding to color absorbing layer
• Color absorbing layer blocks light of specific colors

Potential Applications

The technology described in the patent application could be applied in:

• Display devices
• Lighting systems
• Signage

Problems Solved

This technology helps in:

• Controlling the emission of light of different colors
• Enhancing color accuracy in displays
• Improving contrast in lighting systems

Benefits

The benefits of this technology include:

• Better color reproduction
• Improved image quality
• Enhanced visual experience

Potential Commercial Applications

The technology could be commercially applied in:

• Television displays
• Smartphone screens
• LED lighting systems

Possible Prior Art

One possible prior art for this technology could be the use of color filters in display devices to control the emission of light of different colors.

What are the manufacturing processes involved in creating the layers of the display device?

The manufacturing processes involved in creating the layers of the display device include deposition techniques such as physical vapor deposition (PVD) or chemical vapor deposition (CVD) for applying the different layers onto the substrates. Additionally, photolithography techniques may be used to define the patterns on the layers.

How does the color absorbing layer effectively block light of specific colors?

The color absorbing layer is designed to have specific optical properties that allow it to absorb light of certain wavelengths corresponding to the colors that need to be blocked. This can be achieved through the selection of materials with appropriate absorption characteristics or by incorporating dyes or pigments that selectively absorb specific colors.

Original Abstract Submitted

a display device includes a first display substrate including a light emitting element which emits light of a first color or light of a second color different from the first color, a second display substrate including in order toward the first display substrate, a layer including both a bank layer defining an opening and a wavelength control pattern in the opening, a capping layer covering the wavelength control pattern and the bank layer, and a color absorbing layer which corresponds to the bank layer and blocks the light of the first color and the light of the second color. the capping layer includes a first area corresponding to the color absorbing layer, the bank layer includes a second area corresponding to the color absorbing layer, and the first area of the capping layer is between the color absorbing layer and the second area of the bank layer.
