Transparent Display Panel Pixel Segmentation for Resolution and Transparency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transparent display panels face a trade-off between high resolution, transparency, and luminance, where increasing the number of light-emitting elements or resolution leads to decreased transparency and luminance due to the larger non-transparent region and smaller transparent region.
Innovation Solution
A transparent display panel design where each unit pixel includes a non-transparent region with two light-emitting elements and a transparent region with a third light-emitting element, optimizing the area distribution to maintain high transparency and luminance, with the third light-emitting element being equal to or larger than the transparent region and using organic light-emitting diodes with transparent electrodes in the transparent region and various electrode types in the non-transparent region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of light-emitting elements is increased to improve resolution, then the resolution is improved, but the transparency and luminance deteriorate due to increased non-transparent region area
Solution Approach 1:
The display panel is segmented into transparent regions and non-transparent regions within each pixel. The transparent region contains a transparent light-emitting element that allows light transmission, while the non-transparent region contains conventional light-emitting elements. This segmentation enables different parts of the same display to serve different functions (transparency vs. light emission), resolving the contradiction between resolution and transparency.
Solution Approach 2:
Different regions of the display panel are assigned different optical properties. The transparent region uses transparent electrodes and materials optimized for light transmission, while the non-transparent region uses conventional materials optimized for light emission. This local differentiation allows each region to optimize its specific function without compromising the other, achieving both high resolution and maintained transparency.

AI summary
A transparent display panel includes a plurality of unit pixels. Each of the unit pixels includes a non-transparent region in which a first light-emitting element that generates and outputs first color light and a second light-emitting element that generates and outputs second color light are disposed and a transparent region in which a third light-emitting element that generates and outputs third color light is disposed.
