Bending-Area Display Structure for Dead Space and Static Electricity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in minimizing dead space and reducing static electricity inflow, particularly in bendable or foldable designs, which affect portability and aesthetic appeal.
Innovation Solution
The display device incorporates a display panel with a substrate, a first conductive layer, and a second conductive layer, where the panel upper member protrudes more towards the bending area than the second conductive layer, and includes an insulating layer with a contact hole for connection, along with a panel upper member that covers the display and bending areas with varying adhesive forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the non-display area width is reduced to increase immersion and aesthetic sense, then the display area appears larger and more immersive, but dead space cannot be effectively minimized and static electricity inflow increases
Solution Approach 1:
The patent segments the non-display area into a bending area with multiple layers (substrate, first conductive layer, second conductive layer, insulating layer) and a non-bending area. This segmentation allows the bending area to serve dual purposes: maintaining aesthetic appearance while providing static electricity shielding functionality through the stacked conductive layers, thus reducing dead space without increasing static electricity inflow.
Solution Approach 2:
The patent introduces an intermediary bending area structure between the display area and the external environment. This bending area with stacked conductive layers acts as a mediator that blocks static electricity from the external environment while maintaining the visual aesthetic of the display device, thereby reducing dead space without allowing static electricity inflow.
2Area of stationary object
If the non-display area width is reduced to increase immersion and aesthetic sense, then the display area appears larger and more immersive, but dead space is not minimized
Solution Approach 1:
The patent segments the non-display area into a bending area with multiple layers (substrate, first conductive layer, second conductive layer, insulating layer) and a non-bending area. This segmentation allows the bending area to serve dual purposes: maintaining aesthetic appearance while providing static electricity shielding functionality through the stacked conductive layers, thus reducing dead space without increasing static electricity inflow.
Solution Approach 2:
The patent implements a nested structure where the first conductive layer and second conductive layer are stacked within the bending area, with the insulating layer between them. This nested multi-layer configuration maximizes the utilization of the non-display area, reducing dead space while maintaining aesthetic appearance and providing static electricity shielding functionality.
3Area of stationary object
If conductive layers are extended to minimize dead space, then the structural layout is optimized, but static electricity inflow may increase without proper insulation
Solution Approach 1:
The patent introduces an intermediary insulating layer between the first conductive layer and the second conductive layer in the bending area. This insulating layer acts as a mediator that prevents direct electrical connection between the conductive layers, ensuring static electricity shielding reliability while allowing the conductive layers to extend into the non-display area for dead space reduction.
Solution Approach 2:
The patent applies different properties to different parts of the bending area: the first conductive layer and second conductive layer provide static electricity shielding, while the insulating layer between them provides electrical isolation. This local differentiation of properties ensures both dead space reduction and static electricity shielding reliability.

AI summary
A display device includes: a display panel including a display area, and a bending area at one side of the display area; and a panel upper member on the display panel. The display panel further includes: a substrate; a first conductive layer on the substrate in the bending area; and a second conductive layer on the first conductive layer at one side of the bending area. One end of the panel upper member facing toward the bending area is more protruded toward the bending area than one end of the second conductive layer facing toward the bending area.
