Display Screen Connection Layout for Narrow-Bezel Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with display functions have electronic components arranged diffusely around the edges of the display output area, resulting in a large width outside the edges, which is inefficient and may increase manufacturing costs.
Innovation Solution
The display screen and electronic device incorporate deformable connection lines that are arranged to form a smaller width than the data lines, allowing them to be bent towards the backside of the display, reducing the number of components visible from the edge and minimizing the width of the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic components are arranged diffusely around the edges of the display output area, then the display can be fully functional, but the width outside the edges becomes large
Solution Approach 1:
The connection lines are bent towards the backside of the display, transitioning from a two-dimensional arrangement on the front surface to a three-dimensional configuration that extends to the rear surface. This dimensional change allows connection lines to be routed through the thickness of the display assembly, reducing the lateral width required for component arrangement.
Solution Approach 2:
The connection lines are designed with deformable characteristics, allowing them to be bent and flexed during assembly and operation. This dynamic flexibility enables the connection lines to adapt to spatial constraints and be routed efficiently through the display structure, minimizing the overall width while maintaining electrical connectivity.
2Reliability
If more connection lines are used to connect data lines to the connection terminal, then the electrical connection is more reliable, but the width occupied by connection lines increases
Solution Approach 1:
Multiple connection lines are routed towards the backside of the display, utilizing the depth dimension to accommodate multiple conductors without increasing the lateral width. This allows the necessary number of connection lines to be packed efficiently through the thickness of the assembly rather than spreading them out horizontally.
Solution Approach 2:
The connection lines are integrated into the overall display structure by routing them through the body thickness, merging the electrical connection function with the structural framework. This integration allows multiple connection lines to share the space within the display assembly volume rather than occupying additional lateral space.
3Ease of manufacture
If connection lines are arranged on the front surface, then assembly is simpler, but the visible width of the frame increases
Solution Approach 1:
Instead of routing connection lines on the front surface as is conventional, the design inverts the approach by routing connection lines to the backside of the display. This inversion moves the visible components to the rear surface, making them invisible from the front view and thereby reducing the apparent frame width while maintaining assembly feasibility.
Solution Approach 2:
The connection lines are extracted from the front-surface arrangement and relocated to the backside of the display assembly. This extraction removes the visual clutter from the front view, reducing the visible frame width, while the connection terminal remains accessible for external connections.

AI summary
A display screen includes: a body, having a first surface including a display output area; and a connection terminal, where the display screen includes M data lines, each corresponding to a column in N display pixel units forming the display output area; the M data lines are arranged to form a first width; each data line corresponds to a connection line; the M connection lines are arranged to form a second width, the second width being smaller than the first width; the M connection lines are arranged on the display output area; the M connection lines extend from the body at the second width and are connected to the connection terminal; the M connection lines are deformable, and both M and N are greater than or equal to 1.
