Outer Structure Spacing in Display Device Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in display device manufacturing is the increasing cost and complexity, particularly in minimizing dead space between the display driving module and the cover window, and reducing damage caused by the pressing of the display driving module during the manufacturing process, while also improving process efficiency.
Innovation Solution
A display device design that includes a display driving module, a cover window with a central and curved portion, and an outer structure positioned between the display driving module and the curved portion, which is spaced apart from the display driving module. This design uses a manufacturing apparatus with molds to form the outer structure by injecting and curing paste, minimizing contact and damage during the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the outer structure is positioned close to the display driving module to minimize dead space, then the area utilization is improved, but the damage risk to the display driving module increases due to pressing during manufacturing
Solution Approach 1:
The outer structure serves as an intermediary element positioned between the curved portion of the cover window and the display driving module. It directly contacts the curved portion while being spaced apart from the display driving module, thereby mediating the mechanical interaction and preventing direct pressing forces from reaching the display driving module during manufacturing and assembly processes.
2Reliability
If the outer structure is spaced apart from the display driving module to reduce damage risk, then the reliability is improved, but the dead space increases reducing area utilization
Solution Approach 1:
The outer structure functions as a protective intermediary that is deliberately spaced apart from the display driving module. This spacing creates a protective gap that prevents direct transmission of pressing forces, while the outer structure itself maintains structural integrity and directly contacts the curved portion of the cover window to provide continuous protection.
Solution Approach 2:
The outer structure extends in the thickness direction of the display device, creating a three-dimensional protective barrier. By utilizing the thickness dimension, it can be positioned to directly contact the curved portion while maintaining spacing from the display driving module in the planar direction, thus reducing dead space while maintaining protection.
3Stability of the object's composition
If the outer structure directly contacts the curved portion to provide support, then the structural stability is improved, but the complexity of the assembly increases
Solution Approach 1:
The outer structure performs multiple functions simultaneously: it directly contacts the curved portion to provide structural support and stability, acts as a protective barrier for the display driving module, and serves as an integral part of the overall device assembly. This multi-functionality reduces the need for separate components and simplifies the overall assembly process.
