Blocking Member Controls Resin Flow in Portable Display Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable display devices face challenges in controlling resin flows during assembly, leading to potential resin spillage and increased manufacturing costs due to the complexity of the process and the high cost of resin barriers.
Innovation Solution
A portable display device design that incorporates a blocking member, such as a double-sided adhesive tape or resin with higher viscosity, strategically placed between the display region and the drive circuit region to prevent resin infiltration, along with a method of annealing the attaching member using ultraviolet light for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a resin is used as an attaching member to attach the display panel to the window, then the attachment strength is improved, but the resin may flow and infiltrate into the drive circuit region causing manufacturing defects
Solution Approach 1:
A blocking member is preliminarily arranged on the boundary line between the drive circuit region and display region before the attaching member is applied. This blocking member creates a physical barrier that prevents the attaching member from infiltrating into the drive circuit region, thereby solving the resin flow control issue while maintaining attachment strength
2Manufacturing precision
If complex barrier materials are used to control resin flows, then the resin infiltration is prevented, but the manufacturing cost and device complexity increase
Solution Approach 1:
Instead of using complex barrier materials throughout the entire structure, the blocking member is strategically placed only at the critical boundary line between the drive circuit region and display region. This localized approach provides effective resin flow control while minimizing device complexity and manufacturing cost
3Area of stationary object
If the attaching member is allowed to flow freely to ensure complete coverage, then the attachment coverage is improved, but the resin spills from the display panel creating defects
Solution Approach 1:
The blocking member acts as an intermediary element positioned at the boundary line. It allows the attaching member to flow freely and achieve complete coverage within the display region while simultaneously preventing the attaching member from spilling into the drive circuit region, thus resolving the contradiction between coverage and spillage prevention

AI summary
A portable display device may include a display panel, a window, an attaching member and a blocking member. The display panel may have a drive circuit region and a display region. The window may be positioned facing to the display panel. The attaching member may be interposed between the display region of the display panel and the window to attach the display panel to the window. The blocking member may be arranged on a boundary line between the drive circuit region and the display region to prevent the attaching member from infiltrating into the drive circuit region. Thus, flows of the attaching member may be readily controlled using the blocking member having a simple structure to prevent the infiltration of the attaching member into the drive circuit region. As a result, the portable display device may be assembled by a simple process and a low cost.
