DISPLAY APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17938746 titled 'DISPLAY APPARATUS

Simplified Explanation

The patent application describes a display apparatus that uses organic light emitting diode (OLED) technology and color conversion layers to produce light of a predetermined color. The apparatus includes blue and green light-emitting units stacked in the OLED structure, and quantum dot-based color conversion layers on certain pixels.

• The display apparatus includes an OLED structure with blue and green light-emitting units.
• Color conversion layers, containing quantum dots, are placed on specific pixels to convert mixed incident light into a predetermined color.
• Color filters are also used on the pixels to absorb or block light of specific wavelengths.
• The patent application specifies a conversion value for the green incident light, based on the difference between the wavelength at maximum transmittance of the second color filter and the medial wavelength of the incident green light.

Potential applications of this technology:

• High-quality displays for electronic devices such as smartphones, tablets, and televisions.
• Improved color accuracy and vibrancy in OLED displays.
• Enhanced viewing experience for users.

Problems solved by this technology:

• OLED displays often struggle with color accuracy and vibrancy, which this technology aims to address.
• The use of color conversion layers and filters helps to achieve more precise and vibrant colors.

Benefits of this technology:

• Improved color accuracy and vibrancy in OLED displays.
• Enhanced viewing experience for users, with more realistic and vibrant colors.
• Potential for more energy-efficient displays due to the use of OLED technology.

Original Abstract Submitted

A display apparatus includes: an organic light emitting diode (OLED) structure including in which at least one blue light-emitting unit and at least one green light-emitting unit are stacked to provide incident light in which the blue incident light and the green incident light are mixed; a first pixel, a second pixel, and a third pixel disposed on the OLED structure; color conversion layers disposed on at least two of the first, the second, or the third pixels, and including quantum dots for converting the mixed incident from the OLED structure into light of a predetermined color; and first, second, and third color filters disposed on the first, the second, and the third pixels, respectively, to absorb or block light of a predetermined wavelength band, wherein a conversion value of an area of a spectrum in a wavelength region of 380 nanometers to 780 nanometers of the green incident light with respect to a difference between a wavelength at the maximum transmittance of the second color filter and the medial wavelength of the incident green light (Δλ) may be 3.6 or greater and 13 or less.
