Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch panel LCD devices are susceptible to impurity introduction through gaps between the outer protecting layer and the touch panel frame, which can degrade display panel performance.
Innovation Solution
A display device design featuring a transparent protective portion, top and bottom chassis, adhesive members, and a sealing portion formed from a thermally curable liquid resin that fills the gaps between the display panel and the chassis, preventing impurities from entering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If gaps are left between the outer protecting layer and touch panel frame for assembly, then ease of manufacture is improved, but impurity introduction increases
Solution Approach 1:
The patent introduces a sealing portion as an intermediary component between the outer protecting layer and the touch panel frame. This sealing portion fills the gaps that would otherwise allow impurity introduction, while still permitting assembly operations. The sealing portion acts as a mediator that reconciles the need for assembly access with the need to prevent impurity entry.
Solution Approach 2:
The sealing portion is implemented as a flexible sealing structure that can conform to the gaps between components. This flexible sealing film or shell structure allows for assembly tolerance while maintaining impurity barrier functionality, adapting to the spatial relationships between the outer protecting layer and frame.
2Manufacturing precision
If adhesive members are applied at predetermined intervals on the outer periphery, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The adhesive members are segmented and arranged at predetermined intervals along the outer periphery of the display panel rather than being continuously applied. This segmentation approach provides precise positioning and spacing control, ensuring uniform distribution while simplifying the application process compared to continuous adhesive application.
Solution Approach 2:
The adhesive members are strategically positioned at specific locations along the outer periphery where they are most needed for secure attachment. This local quality approach concentrates adhesive application at critical points rather than uniformly across the entire periphery, improving manufacturing precision while reducing overall material usage and complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively seals the gaps between the display panel and the chassis, preventing impurities from entering and maintaining the display panel's performance by using a thermally curable liquid resin to form an adhesive and sealing layer.
Implementation Method 1
a sealing portion formed to fill at least part of the space between i) a sidewall portion of the display panel and ii) the top chassis and bottom chassis... the adhesive layer and the sealing portion may be formed from a thermally curable liquid resin

AI summary
A display device and a method for manufacturing the same are disclosed. In one embodiment, the display device includes: i) a display panel configured to display an image via a display surface; a transparent protective portion formed over the display panel, ii) a top chassis formed between the transparent protective portion and the display panel and iii) a bottom chassis formed below the display panel and coupled to the top chassis so as to protect the display panel. The display device may further include 1) a plurality of adhesive members arranged at predetermined intervals on an outer periphery of the display surface of the display panel so as to attach the display panel to the top chassis, 2) an adhesive layer formed between the display panel and the transparent protective portion and 3) a sealing portion formed to fill at least part of the space between i) a sidewall portion of the display panel and ii) the top chassis and bottom chassis.
