Free-Shape Display Region via Segmented Substrate and Compensation Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with rectangular shapes cannot achieve desirable circular or ellipse-like display regions due to limitations in driving unit dispositions, failing to meet consumer requirements for creative and free-shape displays.
Innovation Solution
A display device comprising a first substrate, a second substrate with arc edges, and a compensation panel with corresponding arc edges and sides, allowing the formation of a display region close to a circular shape by aligning and assembling these components to create a free-shape display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional display panels use rectangular shapes with standard driving unit dispositions, then the manufacturing process is simple and driving units are easily arranged, but the display region cannot achieve desirable circular or ellipse-like free shapes
Solution Approach 1:
The display device is divided into multiple substrates (first substrate, second substrate, compensation panel) with different functions. The driving units are disposed only on the first substrate while the second substrate and compensation panel form the free-shape display region without driving units, segmenting the functional areas to achieve both simple driving unit arrangement and free-shape display region
Solution Approach 2:
The driving units are extracted from the free-shape display region and placed only on the first substrate. This extraction allows the second substrate and compensation panel to form a complete free-shape display region without the complexity of arranging driving units in curved or circular patterns
2Shape
If display panels undergo free-shape cutting process to achieve arc edges, then the display region can have curved edges, but the driving unit dispositions still limit the display region from forming complete circular or ellipse shapes
Solution Approach 1:
The display device is segmented into multiple substrates where the free-shape cutting is applied only to the second substrate and compensation panel, while the first substrate maintains a standard shape for easy manufacturing of driving units. This segmentation allows free-shape display region without complicating the manufacturing of driving unit substrates
Solution Approach 2:
The first substrate acts as an intermediary that carries the driving units and connects to the second substrate and compensation panel. This intermediary structure allows the driving units to be manufactured on a standard substrate while the final assembly achieves the free-shape display region
