Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of reducing the size of the peripheral area in display devices is hindered by the increasing area occupied by driving units in high-resolution and high-speed driving processes, limiting the expansion of the display area.
Innovation Solution
A display device design that includes a substrate with intersecting scan lines, a first and second display area, and a driving circuit unit partially disposed in the second display area, allowing for expanded display area by overlapping the second light-emitting element with the driving circuit unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the driving unit area is increased to support high-resolution and high-speed driving, then the driving performance is improved, but the display area is reduced
Solution Approach 1:
The scan lines are configured to intersect each other at angles other than parallel arrangement, creating a crisscross pattern that allows driving circuits to be positioned in the intersecting regions. This spatial reorganization enables the display area to extend into regions previously occupied by peripheral driving circuits, effectively increasing display area while maintaining high-resolution driving capability.
Solution Approach 2:
The intersecting scan line structure serves multiple functions: it provides signal transmission pathways, defines pixel boundaries, and creates spatial zones for integrating driving circuits within the display region. This multi-functional design allows the same structural elements to support both high-speed driving operations and expanded display coverage.
2Area of stationary object
If the peripheral area is reduced to enlarge the display area, then the display area is expanded, but the driving unit becomes insufficient
Solution Approach 1:
By transitioning from parallel scan lines to intersecting scan lines at angles, the patent creates a crisscross pattern that generates additional spatial zones within the display region. These intersecting regions serve as new locations for placing driving circuits, effectively moving driving functionality from the peripheral area into the display area without compromising driving capability.
3Device complexity
If scan lines are arranged in a traditional parallel manner, then the layout is simple, but the display area cannot be expanded
Solution Approach 1:
The patent introduces intersecting scan lines that cross at various angles, transforming the traditional two-dimensional parallel grid into a more complex multi-directional pattern. This angular arrangement creates additional spatial zones and allows driving circuits to be positioned within the intersecting regions, thereby expanding the display area beyond the limitations of parallel scan line configurations.
