Transparent Display Peripheral Wiring Layout for Uniform Transparency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices that allow the back to be visible while displaying an image often have a difference in transparency between the display region and the peripheral region due to the arrangement of pixels and wiring, affecting the overall appearance.
Innovation Solution
A display device design featuring a first wiring pattern connecting scanning signal lines diagonally and a second wiring pattern with common voltage applied, both overlaid with a light shielding layer to maintain uniform transparency across the display and peripheral regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wiring patterns are arranged in the peripheral region to connect driver circuits and signal lines, then electrical connectivity is achieved, but transparency uniformity deteriorates due to visible wiring structures
Solution Approach 1:
The patent applies a light shielding layer with a stripe pattern that matches the wiring pattern configuration. This layer absorbs or blocks light passing through the wiring regions, making the wiring structures invisible or significantly less visible. The stripe pattern is specifically designed to align with the first and second wiring patterns, effectively camouflaging them while maintaining electrical connectivity functionality.
Solution Approach 2:
The patent employs a composite structure combining the light shielding layer with the underlying wiring patterns and liquid crystal layer. The light shielding layer acts as an optical filter that modifies the appearance of the peripheral region, creating a composite effect where the wiring structures are functionally present but optically hidden, thus achieving both connectivity and appearance uniformity.
2Stability of the object's composition
If the peripheral region is made transparent to enhance design, then aesthetic appearance is improved, but wiring visibility increases causing visual discomfort
Solution Approach 1:
The light shielding layer introduces optical absorption properties to specific regions where wiring patterns exist. By applying this layer with a stripe pattern aligned to the wiring, the peripheral region maintains its transparency for aesthetic purposes while the wiring areas become optically dark or invisible, eliminating the harmful effect of visible wiring.
Solution Approach 2:
The light shielding layer serves as an intermediary element between the transparent peripheral region and the underlying wiring structures. It selectively blocks light in wiring regions while allowing light transmission in non-wiring areas, thus mediating between the desire for transparency and the need to hide wiring.
