Display Panel Adhesive Positioning for Polarizer Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in downsizing due to the configuration of the backlight frame surrounding the display panel, which can lead to damage of the rear polarizing plate during assembly.
Innovation Solution
A display apparatus configuration where the display panel is bonded to the backlight frame using an adhesive member, with the polarizing plate positioned on the inner side of the frame, reducing the risk of damage and allowing for downsizing by minimizing the space between the adhesive member and the polarizing plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the backlight frame surrounds the display panel, then the display device structure is stable, but the device size cannot be reduced
Solution Approach 1:
The backlight frame is divided into a first backlight frame portion and a second backlight frame portion that are positioned at different depths relative to the display panel. This segmentation allows the frame to provide structural support while reducing the overall device volume by eliminating the need for a single large surrounding frame.
2Ease of manufacture
If the rear polarizing plate is exposed from the fixing member, then the assembly process is simple, but the polarizing plate may be damaged
Solution Approach 1:
A protective film is introduced as an intermediary layer between the second backlight frame portion and the rear polarizing plate. This protective film prevents direct contact and potential damage to the polarizing plate during assembly, while still allowing the assembly process to proceed efficiently.
3Volume of moving object
If the adhesive member is positioned closer to the polarizing plate, then the device can be downsized, but the risk of polarizing plate damage increases
Solution Approach 1:
The protective film serves as a mediator between the adhesive member and the rear polarizing plate, enabling the adhesive to be positioned closer to the polarizing plate for downsizing while preventing direct harmful contact that could cause damage during the bonding process.
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 suppresses damage to the polarizing plate during assembly, enables downsizing of the display apparatus, and simplifies the assembly process by reducing the number of parts and improving positional accuracy of the adhesive member.
Implementation Method 1
a backlight frame (60), and a display panel (200). The display panel (200) is bonded to a top portion of the backlight frame (60) through an adhesive member (70)
