Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices, such as liquid crystal displays, face challenges in achieving a thin profile and maintaining visibility due to their complex structure, which includes a display panel with a front and back substrate, an optical layer, and a frame, making it difficult to optimize the display's thickness and visibility.
Innovation Solution
The display device incorporates a supporting film attached to the display panel and connected to the frame, with a fastening system that includes a back cover and side cover, and an optical layer with a reflective polarizer, vertical and horizontal prism sheets, and a diffusion plate to enhance light distribution and reduce light leakage, while also using a buffer with elasticity to absorb external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex structure including display panel, optical layer, and frame is used, then the display device can achieve proper functionality, but the thickness cannot be reduced and visibility is compromised
Solution Approach 1:
The patent combines the optical layer with the frame structure by positioning the optical layer between the display panel and the frame, and using the supporting film to attach both components together. This integration reduces the overall thickness while maintaining the functional integrity of both the display and optical components.
Solution Approach 2:
The patent employs a thin supporting film to attach the optical layer to the frame and connect the display panel to the frame. This thin film structure reduces the overall thickness of the display device while maintaining structural integrity and allowing for a more compact design.
2Reliability
If a complex structure with multiple components is used, then the display device achieves proper functionality, but the structural complexity increases
Solution Approach 1:
The frame serves multiple functions: it provides structural support, holds the optical layer in position, and is connected to the display panel through the supporting film. The supporting film also serves dual purposes by attaching the optical layer to the frame and connecting the display panel to the frame, thereby reducing the need for separate components.
Solution Approach 2:
The patent merges the functions of structural support and optical element mounting by integrating the optical layer into the frame structure. This combination reduces the number of separate components and simplifies the overall structure while maintaining proper display functionality.
3Illumination intensity
If the optical layer is positioned between the display panel and frame, then light distribution is improved, but the structural complexity increases
Solution Approach 1:
The optical layer is integrated into the frame structure, combining the light distribution function with the structural support function. This integration improves light distribution while minimizing the increase in structural complexity through the use of the supporting film for attachment.
Solution Approach 2:
The thin supporting film allows the optical layer to be positioned between the display panel and frame without significantly increasing structural complexity. The film provides a simple attachment mechanism that accommodates the optical layer while maintaining a compact overall structure.
