Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex and costly stacked structure of traditional anti-peep films in display panels poses a technical challenge, as it complicates the manufacturing process and increases costs.
Innovation Solution
A display panel design incorporating a first substrate, a second substrate with liquid crystal molecules, a light-shielding layer with patterns, a color film layer, and an anti-peep structure that uses liquid crystal molecules and a control member to block or deflect light based on the viewing angle, eliminating the need for an external anti-peep film by integrating the anti-peep function into the panel's internal structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional anti-peep film with ultra-fine louver structure is hung on the display panel, then privacy protection is achieved, but the stack structure becomes complicated and costly
Solution Approach 1:
The patent merges the anti-peep function with the display panel's internal structure by integrating a light-shielding layer with light-shielding patterns directly into the panel. This eliminates the need for a separate external anti-peep film, thereby simplifying the overall stack structure while maintaining privacy protection functionality.
Solution Approach 2:
The light-shielding layer serves multiple functions: it provides privacy protection through its light-shielding patterns, and it is integrated into the display panel structure itself. This multi-functional design reduces the number of separate components needed, simplifying the overall structure.
2Object-affected harmful factors
If a traditional anti-peep film with ultra-fine louver structure is hung on the display panel, then privacy protection is achieved, but manufacturing cost increases
Solution Approach 1:
By combining the anti-peep functionality into the display panel's existing light-shielding layer, the patent eliminates the need to manufacture and assemble a separate anti-peep film. This integration reduces material costs and manufacturing complexity, making the overall production more cost-effective.
Solution Approach 2:
The display panel's own light-shielding layer is utilized to provide anti-peep functionality, rather than requiring an additional external component. This self-service approach leverages existing structures to achieve multiple functions, reducing overall manufacturing costs.
3Adaptability or versatility
If the viewing angle is increased to close to 180 degrees, then viewing experience without blind spots is achieved, but privacy protection becomes compromised
Solution Approach 1:
The patent implements a switchable anti-peep mode that can be activated or deactivated. When activated, the light-shielding patterns block oblique viewing angles to protect privacy, while when deactivated, the full 180-degree viewing angle is maintained. This dynamic switching allows the system to adapt to different usage scenarios.
Solution Approach 2:
The patent changes the optical parameters of the display panel by introducing light-shielding patterns that can selectively block light at different angles. By adjusting the presence or absence of these patterns' effect, the system can switch between wide viewing angle mode and privacy protection mode.

Function Achieved in This Case
This solution allows for cost-effective and simplified manufacturing by eliminating the need for external anti-peep films, while enabling free switching between non-anti-peep and anti-peep modes, effectively addressing the issue of privacy protection without the complexity of traditional anti-peep film structures.
Implementation Method 1
the control member is configured to control the liquid crystal molecules in the anti-peep structure to deflect at a predetermined angle
