Display Device Bezel Reduction via Nested Support Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual cell panel display devices face challenges in achieving a narrow bezel while maintaining structural stability, as the increased weight and gravity cause peeling forces on adhesive tapes, leading to a higher risk of display panels falling off, especially when tilted or under high temperature conditions.
Innovation Solution
The display device incorporates a panel assembly with a first and second display panel supported by a backlight module, where the first supporting part extends into the accommodation space defined by the panels, overlapping with the side frame to prevent separation and using adhesive layers and buffer layers to secure the panels, thereby reducing the bezel width and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dual cell panel technology is used to improve contrast and control capability, then display performance is improved, but bezel width increases
Solution Approach 1:
The first display panel is nested within the accommodation space formed by the second display panel and the first supporting part. The first supporting part extends into the accommodation space to provide structural support while allowing the first display panel to be positioned closer to the backlight module, thereby reducing the bezel width while maintaining display performance
Solution Approach 2:
The first supporting part extends in a direction towards the middle part of the backlight module, utilizing the depth dimension of the display device. This vertical extension into the accommodation space allows the first display panel to be repositioned, reducing the horizontal bezel width without compromising structural stability
2Ease of manufacture
If adhesive tapes are used to secure display panels, then assembly is simplified, but structural stability deteriorates under tilt and high temperature conditions
Solution Approach 1:
The first supporting part acts as an intermediary structural element between the first display panel and the backlight module. It provides mechanical support and positioning, reducing reliance on adhesive tapes alone to maintain panel stability under various conditions including tilt and high temperature
Solution Approach 2:
The connection layer combines adhesive materials with the first and second display panels to create a composite bonding structure. This composite approach enhances the overall bonding strength and stability while maintaining ease of assembly through a unified connection mechanism
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
This configuration effectively prevents the display panels from falling off when tilted and maintains a narrow bezel by providing a blocking effect with the first supporting part and secure adhesion through the connection layer, while the buffer layers prevent collisions and enhance structural stability.
Implementation Method 1
a first adhesive layer is disposed on a surface of each side frame facing the backlight module, and the backlight module is adhered to each side frame through the first adhesive layer
Implementation Method 2
a second adhesive layer is disposed between the second supporting part and the second display panel
Implementation Method 3
the connection layer includes an adhesive layer
