Display Device Side Frame Covers Recess for Circuit Board
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat display devices face issues with the strength and planarity of the bonded protection element due to the recess configuration in the frame housing, leading to reduced reliability.
Innovation Solution
A display device design that includes a display module with a frame housing and a side frame, where the connecting circuit board passes through a recess in the frame housing, and the side frame covers the connecting circuit board, recess, and first side, enhancing the bonding surface for the protection element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the frame housing uses a recess configuration to accommodate the connecting circuit board, then the control circuit board can be disposed at the rear side of the display module, but the bonding surface area between the protection element and the frame housing is reduced, resulting in worse strength and planarity
Solution Approach 1:
The side frame extends in a direction perpendicular to the recess, creating an additional dimensional structure that covers the recess area. This allows the protection element to bond to both the frame housing and the side frame, effectively increasing the bonding surface area without compromising the recess configuration needed for circuit board accessibility.
2Ease of operation
If the frame housing uses a recess configuration to accommodate the connecting circuit board, then the control circuit board can be disposed at the rear side of the display module, but the planarity of the bonded protection element deteriorates
Solution Approach 1:
The side frame provides an extended bonding surface that compensates for the non-planar recess area. By covering the recess with the side frame structure, the protection element can maintain planarity across the entire bonding surface, including over the recess region, thus improving overall planarity while preserving circuit board accessibility.
3Ease of operation
If the frame housing uses a recess configuration to accommodate the connecting circuit board, then the control circuit board can be disposed at the rear side of the display module, but the reliability of the display device is reduced
Solution Approach 1:
The side frame creates an additional structural element that enhances the overall reliability by providing extra bonding area and improved mechanical support. This compensates for the potential weakness introduced by the recess configuration, ensuring that the protection element is securely bonded while maintaining circuit board accessibility.
