ORGANIC LIGHT EMITTING DISPLAY APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240224759 titled 'ORGANIC LIGHT EMITTING DISPLAY APPARATUS
The abstract discusses an organic light-emitting display apparatus with multiple pixels on a substrate, each containing subpixels with emission regions, a planarization layer with a light extraction pattern, and a light emitting device layer.
- Each subpixel has a light extraction pattern with concave portions and a rotation angle with respect to a reference point.
- The emission region of each subpixel includes a reference point located at a concave portion of the light extraction pattern.
- The light emitting device layer is on the light extraction pattern of each subpixel.
Potential Applications: - This technology can be used in high-resolution displays for smartphones, tablets, and TVs. - It can also be applied in augmented reality and virtual reality devices for enhanced visual experiences.
Problems Solved: - Enhances light extraction efficiency from subpixels, leading to brighter and more vibrant displays. - Improves overall display quality and color accuracy.
Benefits: - Increased brightness and color accuracy in display screens. - Enhanced visual experience for users in various applications.
Commercial Applications: Organic light-emitting display technology can revolutionize the consumer electronics market by providing high-quality displays for a range of devices, from smartphones to TVs.
Questions about Organic Light-Emitting Display Technology: 1. How does the light extraction pattern improve the efficiency of subpixels in organic light-emitting displays? 2. What are the key advantages of using organic light-emitting display technology in consumer electronics?
Original Abstract Submitted
discussed in an organic light emitting display apparatus, which can include a plurality of pixels on a substrate, each pixel including a plurality of subpixels, and each of the plurality of subpixels having an emission region, a planarization layer including a light extraction pattern, the light extraction pattern disposed at the emission region of each of the plurality of subpixels and including a plurality of concave portions; and a light emitting device layer on the light extraction pattern of each of the plurality of subpixels. the emission region of each of the plurality of subpixels includes a reference point disposed at a concave portion of the plurality of concave portions. the light extraction pattern of each of the plurality of subpixels has a rotation angle with respect to the reference point.
