Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Phase film substrates used in 3D display technology often experience deformation and display distortion due to the flexible nature of their base film, leading to misalignment with pixel units on display panels, which affects the quality of the 3D image.
Innovation Solution
A phase film substrate with a liquid crystal polymer layer comprising strip-shaped sub-layers that gradually decrease in width from the center to the edges, aligned to match the pixel units on the display panel, reducing deformation and improving alignment during attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the base film is made flexible to enable attachment to display panels, then ease of operation is improved, but deformation occurs leading to misalignment with pixel units
Solution Approach 1:
The liquid crystal polymer layer is designed with non-uniform strip widths that vary across different regions of the base film. The strip width at any position is specifically engineered to correspond to the width of pixel units at that location, creating local adaptation to the display panel's pixel structure. This local quality variation compensates for the deformation caused by the flexible base film during attachment.
Solution Approach 2:
The liquid crystal polymer layer is pre-formed with varying strip widths before the attachment process. This preliminary configuration of different strip widths across the base film surface prepares the phase film substrate to maintain proper alignment with pixel units even after deformation occurs during attachment to the display panel.
2Ease of manufacture
If the liquid crystal polymer layer uses uniform strip widths, then ease of manufacture is improved, but alignment with pixel units deteriorates due to base film deformation
Solution Approach 1:
Instead of using uniform strip widths throughout the liquid crystal polymer layer, the invention implements varying strip widths that are tailored to different regions of the base film. This local variation in strip width ensures that each region of the liquid crystal polymer layer maintains proper alignment with the corresponding pixel units on the display panel, compensating for the deformation that occurs during attachment.
3Manufacturing precision
If the phase film substrate is designed with varying strip widths, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The invention changes the geometric parameter of the liquid crystal polymer layer, specifically the strip width, as a function of position on the base film. By making the strip width a variable parameter rather than a constant, the phase film substrate can adapt to the deformation of the flexible base film during attachment, maintaining alignment precision with pixel units across the entire display surface.

AI summary
Embodiments of the present disclosure provide a phase film substrate, a manufacturing method thereof, and a display device. The phase film substrate includes a base film and a liquid crystal polymer layer on the base film. The liquid crystal polymer layer includes a plurality of strip-shaped liquid crystal sub-layers arranged in parallel in a first direction of the base film. Widths of the plurality of strip-shaped liquid crystal sub-layers in the first direction gradually decrease from a center of the base film to edges of the base film in the first direction, and the first direction is a direction in which the phase film substrate receives force and extends when it is attached to a display panel.
