DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240049552 titled 'DISPLAY DEVICE

Simplified Explanation

The abstract describes a display device that includes a display substrate and a color conversion substrate. The color conversion substrate has defined light transmitting areas and a light blocking area between them. It also includes a low refractive index layer covering a bank in the light blocking area. The color conversion substrate further includes wavelength conversion patterns and a light transmission pattern in the light transmitting areas, which are between the low refractive index layer and the display substrate.

• The display device includes a display substrate and a color conversion substrate.
• The color conversion substrate has defined light transmitting areas and a light blocking area.
• A low refractive index layer covers a bank in the light blocking area.
• The color conversion substrate includes wavelength conversion patterns and a light transmission pattern in the light transmitting areas.
• The low refractive index layer has a refractive index lower than at least one of the wavelength conversion patterns.

Potential applications of this technology:

• Display devices with improved color conversion capabilities.
• Enhanced image quality and color accuracy in displays.
• More efficient use of light in display devices.

Problems solved by this technology:

• Improves color conversion efficiency in display devices.
• Reduces light leakage and improves image quality.
• Provides better control over light transmission and color reproduction.

Benefits of this technology:

• Improved color accuracy and image quality in displays.
• Enhanced efficiency and performance of display devices.
• Better control over light transmission and color conversion processes.

Original Abstract Submitted

a display device includes a display substrate and a color conversion substrate. the color conversion substrate includes: a second base substrate in which first to third light transmitting areas, and a light blocking area between adjacent light transmitting areas are defined, a first bank in the light blocking area, a first low refractive index layer between the second base substrate and the display substrate and covering the first bank. the color conversion substrate further includes a first wavelength conversion pattern in the first light transmitting area, a second wavelength conversion pattern in the second light transmitting area, and a light transmission pattern in the third light transmitting area, which are between the first low refractive index layer and the display substrate. the first low refractive index layer has a refractive index lower than at least one of the first wavelength conversion pattern or the second wavelength conversion pattern.
