Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies lack the ability to switch seamlessly between a peep-proof state and a shared state, resulting in limited application scenarios and poor user experience.
Innovation Solution
A dimmable panel is introduced, comprising a first and second substrate with strip-shaped electrodes and a liquid crystal layer in between. The electrodes are arranged to create an electric field that controls the scattering of collimated light, allowing for a peep-proof state when no voltage is applied and a shared state when voltage is applied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a peep-proof screen is used to prevent information leakage, then security is improved, but viewing flexibility and shared viewing capability deteriorate
Solution Approach 1:
The patent applies a dynamic switching mechanism that allows the display to transition between peep-proof mode and shared viewing mode. The control circuit receives switching signals and adjusts the liquid crystal layer's state accordingly, enabling the screen to dynamically adapt its optical properties based on viewing requirements rather than being fixed in one state.
Solution Approach 2:
The invention changes the optical parameters of the liquid crystal layer by applying different voltages. When voltage is applied, the liquid crystal molecules reorient to allow light passage for shared viewing; when voltage is removed, they return to their original state for peep-proof operation. This parameter change enables seamless transition between security mode and sharing mode.
2Adaptability or versatility
If a liquid crystal layer with strip-shaped electrodes is used to enable state switching, then adaptability between peep-proof and shared states is improved, but device complexity increases
Solution Approach 1:
The electrode structure is segmented into multiple strip-shaped electrodes arranged in a specific pattern between the liquid crystal layer and the viewer. These segmented electrodes create localized electric fields that efficiently control the liquid crystal orientation without requiring a complex full-coverage electrode system, thus achieving state switching with moderate structural complexity.
3Reliability
If the strip-shaped electrodes are arranged with non-overlapping projections to reduce interference, then signal interference is reduced, but electrode area and manufacturing precision requirements increase
Solution Approach 1:
The strip-shaped electrodes are designed with specific local characteristics including controlled width, spacing, and arrangement patterns. The non-overlapping projection design ensures that each electrode's electric field is localized and does not interfere with adjacent electrodes, while the specific dimensions and spacing are optimized to achieve the desired liquid crystal control with feasible manufacturing tolerances.
