Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the cell gap of the lens structural layer is increased to accommodate more lens structures, then the resolution and size increase, but the power consumption increases and the response rate decreases
Solution Approach 1:
The patent introduces a charge-controlling agent that changes the electrical parameters of the liquid-crystal monomers by providing surface charges. This allows the liquid-crystal monomers to be more sensitive to electric fields, enabling faster response and lower power consumption while maintaining the required resolution through the lens structures
Solution Approach 2:
The charge-controlling agent acts as an intermediary between the electric field and the liquid-crystal monomers. It enhances the interaction by providing surface charges that amplify the electric field's influence on the liquid-crystal monomers, allowing for faster switching without increasing power consumption
2Manufacturing precision
If a higher electric field is applied to drive the liquid-crystal monomers for better resolution, then the imaging quality improves, but the power consumption increases
Solution Approach 1:
The charge-controlling agent modifies the electrical parameters of the liquid-crystal monomers by introducing surface charges. This enhances their responsiveness to electric fields, allowing for lower voltage operation while maintaining high imaging quality through improved alignment control
3Speed
If the liquid-crystal monomers are forced to disperse for mode switching, then the switching speed increases, but the stability decreases causing push mura problems
Solution Approach 1:
The charge-controlling agent provides preliminary stabilization by creating surface charges that hold the liquid-crystal monomers in place. This prevents unwanted dispersion during mode switching, maintaining stability while still allowing controlled switching when needed
Solution Approach 2:
The introduction of surface charges on the liquid-crystal monomers changes their interaction parameters with the electric field and with each other. This enhances both their responsiveness to switching signals and their stability in the off state, preventing push mura problems
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus achieves reduced power consumption and increased response rate for mode switching, addressing stability and fatigue issues by using a charge-controlling agent to enhance the alignment and rotation of liquid-crystal monomers, thus improving the overall performance and reducing mura problems.
Implementation Method 1
A charge-controlling agent on a surface of the liquid-crystal monomers such that the influence of the liquid-crystal monomers with respect to the electric field is enhanced
Implementation Method 2
The liquid-crystal monomers are arranged along a direction not refracting light when no electric field is applied, so that each eye of the user can see the images of all the pixels. In addition, the liquid-crystal monomers will be arranged to a direction refracting the light when an electric field is applied
Implementation Method 3
the liquid-crystal monomers will be arranged to a direction refracting the light when an electric field is applied, so that the user's left eye and right eye, respectively, can only see the image of the left-eye pixels and the image right-eye pixels
