Display Panel Recess Structure for Narrow Bezel Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in reducing the bezel size and improving rigidity during the manufacturing process, which affects the overall design and functionality.
Innovation Solution
The display device incorporates a display panel with a circuit element layer featuring recessed portions and protruding portions, a flexible circuit board connecting to a printed circuit board, and a hinge member that overlaps these recessed portions, allowing for a reduced bezel and enhanced rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the bezel size is reduced to achieve a larger display area, then the display area increases, but the structural rigidity and stability during manufacturing deteriorate
Solution Approach 1:
The circuit element layer is segmented into multiple regions including recessed portions and protruding portions. The recessed portions create localized depression areas while protruding portions extend outward, dividing the structure into functional segments that collectively enhance rigidity without increasing overall bezel size
Solution Approach 2:
The invention introduces vertical dimensionality through recessed portions (depressions into the layer) and protruding portions (extensions beyond the layer). This three-dimensional structuring adds structural complexity in the vertical dimension while maintaining a compact horizontal footprint, thereby improving rigidity without expanding the bezel area
2Strength
If recessed portions are added to the circuit element layer to improve rigidity, then structural integrity improves, but device complexity increases
Solution Approach 1:
Recessed portions are strategically positioned at specific locations within the circuit element layer where structural reinforcement is most needed. Rather than uniformly modifying the entire layer, the recesses are localized to critical areas, providing targeted structural support while minimizing overall structural complexity
Solution Approach 2:
The recessed portions and protruding portions are integrated into a single circuit element layer structure, combining multiple structural features into one unified component. This merging approach consolidates what could be separate elements into a single layer, reducing overall device complexity while maintaining structural integrity

AI summary
An electronic apparatus includes a display device to display an image, and an input device unit to output a signal to the display device. The display device includes a display panel including a circuit element layer and defining a display region and a non-display region adjacent to the display region, a printed circuit board including an electronic component, and a flexible circuit board between the display panel and the printed circuit board and electrically connecting the display panel to the printed circuit board, and wherein at least two recessed portions are defined in one side surface of the circuit element layer.
