Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-view display devices face challenges in providing individualized images to viewers due to misalignment issues during manufacturing, leading to decreased yield and image quality, as well as increased costs and damage to the display panel during the attachment process of the barrier substrate.
Innovation Solution
A liquid crystal display device with a barrier pattern on the outer side of the display panel, which adjusts the optical path for multiple viewing angles, and a protection member to prevent damage, along with a method of fabricating the device that forms the barrier pattern on the first substrate, reducing the need for additional substrates and adhesive materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an additional barrier substrate is manufactured and attached to the display panel, then the multi-view display function is achieved, but the manufacturing complexity and cost increase
Solution Approach 1:
The barrier substrate and color filter substrate are merged into a single integrated substrate. The barrier pattern is formed directly on the color filter substrate during the same manufacturing process, eliminating the need for a separate barrier substrate and its attachment process. This integration reduces manufacturing steps, complexity, and potential misalignment issues.
Solution Approach 2:
The color filter substrate serves dual functions: it provides color filtering for the display and simultaneously acts as the barrier substrate for controlling light paths in multi-view directions. This multi-functionality eliminates the need for a dedicated barrier substrate, simplifying the overall device structure and manufacturing process.
2Adaptability or versatility
If the barrier substrate is attached to the display panel, then the multi-view display function is achieved, but misalignment occurs between the display panel and barrier substrate
Solution Approach 1:
By integrating the barrier substrate and color filter substrate into one substrate, the alignment issue between two separate components is completely eliminated. The barrier pattern and color filter pattern are formed on the same substrate during the same manufacturing process, ensuring perfect alignment without requiring additional alignment procedures or adhesive materials.
3Ease of manufacture
If the display panel is etched or grinded before attaching the barrier substrate, then the barrier substrate can be attached, but the display panel is damaged and yield decreases
Solution Approach 1:
The integrated substrate structure eliminates the need for etching or grinding operations on the display panel. Since the barrier pattern is formed directly on the color filter substrate using standard photolithography and etching processes during manufacturing, no post-manufacturing mechanical processing is required, thus preventing damage to the display panel and maintaining high yield.
4Adaptability or versatility
If an attaching material is used to attach the display panel to the barrier substrate, then the components are joined, but additional materials and costs are required
Solution Approach 1:
The barrier substrate and color filter substrate are integrated into a single substrate, completely eliminating the need for attaching materials such as adhesives. This integration removes the associated material costs, additional manufacturing steps, and potential quality issues related to adhesive application and curing.
