Aligning Parallax Separation Sheet with Display Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels with touch screens face challenges in integrating 3D viewing capabilities without compromising touch sensitivity, due to the difficulty in aligning thin and flexible parallax separation sheets with the underlying composite image, which often results in misalignment and reduced touch sensitivity or destroyed touch functions.
Innovation Solution
A method for aligning a parallax separation sheet with a display panel using a rotating and shifting mechanism, combined with cameras and monitors to ensure proper alignment, allowing for the integration of a touch-sensing layer and a parallax separation surface, enabling both 3D viewing and touch sensitivity through the use of lenticular sheets or parallax barriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a parallax separation sheet is integrated with a touch screen display panel to enable 3D viewing, then 3D viewing capability is achieved, but alignment difficulty causes misalignment and reduces touch sensitivity or destroys touch function
Solution Approach 1:
The patent applies preliminary action by pre-forming alignment marks on the parallax separation sheet during its manufacturing process, and pre-defining corresponding alignment marks on the display panel. This preliminary preparation enables automatic alignment through optical detection without requiring manual adjustment during assembly, thereby resolving the alignment precision issue while maintaining 3D viewing capability
Solution Approach 2:
The patent introduces alignment marks as an intermediary element between the parallax separation sheet and the display panel. These marks serve as reference points that facilitate precise alignment through optical detection systems, acting as a mediator that bridges the two components and enables accurate positioning without direct mechanical contact or complex adjustment mechanisms
2Illumination intensity
If a parallax separation sheet is made thin and flexible to maintain display quality, then optical performance is improved, but alignment becomes more difficult and touch sensitivity is compromised
Solution Approach 1:
The patent applies self-service by incorporating alignment marks directly into the parallax separation sheet structure during manufacturing. The sheet itself provides its own alignment references without requiring external fixtures or complex alignment tools, enabling the thin and flexible sheet to self-align with the display panel through optical detection, thus maintaining both optical performance and alignment ease
Solution Approach 2:
The patent replaces mechanical alignment systems with an optical alignment system. Instead of using mechanical fixtures, clamps, or physical adjustment mechanisms to align the thin parallax separation sheet, the invention uses optical detection of alignment marks to determine position and guide alignment, thereby maintaining the sheet's thin and flexible properties while improving alignment ease
