Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent display devices face challenges in achieving high transparency and efficient repair of defective pixels due to the lack of suitable repair structures and methods for transparent pixel structures, which are not addressed by existing technologies designed for opaque display devices.
Innovation Solution
A transparent display panel and device with a novel pixel structure comprising subpixels of different colors arranged in specific patterns, allowing for repair through overlapping repair lines that can connect or disconnect subpixels, enabling effective repair of defective pixels without reducing transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If transparent display panels use traditional opaque repair structures and methods, then defective pixels can be repaired in opaque displays, but the repair structures block light and reduce transparency in transparent displays
Solution Approach 1:
The patent uses transparent thin film structures for repair lines that allow light to pass through while providing repair functionality. The repair lines are formed as thin transparent conductive layers that maintain display transparency unlike traditional opaque repair structures
Solution Approach 2:
The patent employs transparent conductive materials with optical properties matched to the display substrate, making the repair lines invisible or minimally visible. The repair structures are designed to have optical characteristics similar to the surrounding transparent display areas
2Illumination intensity
If transparent display panels implement high transparency by using transparent elements, then transparency is improved, but the ability to repair defective pixels is lost because traditional repair methods are not suitable
Solution Approach 1:
The patent divides the display into modular pixel structures with independent transparent conductive layers that can be selectively repaired. The repair lines are segmented to connect specific subpixels independently, allowing localized repair without affecting the entire display
Solution Approach 2:
The patent introduces transparent conductive layers as intermediary elements between defective pixels and functional pixels. These intermediary transparent conductors enable electrical connection for repair purposes while maintaining optical transparency
3Ease of repair
If transparent display panels use repair lines to connect adjacent pixels, then defective pixels can be repaired, but the repair lines may reduce the overall transparency of the display
Solution Approach 1:
The patent optimizes the optical parameters of repair lines by using transparent conductive materials with minimal absorption and scattering coefficients. The repair lines are designed with controlled thickness and material composition to minimize their impact on light transmission while maintaining electrical functionality

AI summary
Disclosed are a transparent display panel and a transparent display device, which each include a plurality of data lines, a plurality of gate lines, and a plurality of transparent pixels each including a plurality of subpixels which display different colors and are disposed adjacent to each other in a first direction and a transparent area disposed adjacent to a corresponding subpixel in a second direction, thereby enabling a pixel defect such as a dark spot or a hot spot to be repaired and enabling normal driving. To this end, the transparent display panel and the transparent display device each include a repair line overlapping a first transparent pixel and a second transparent pixel adjacent to each other in the second direction in the plurality of transparent pixels.
