Display Apparatus Vertical Circuit Stacking for Expanded Screen Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display apparatuses have a significant non-display area that limits their ability to expand the display area, making it difficult to provide enhanced visual satisfaction and increase user engagement, especially as they become thinner and lighter.
Innovation Solution
The display apparatus is designed with a substrate that includes a first and second area, where gate driving circuit units and pixel circuit units are strategically arranged to reduce the non-display area, allowing for a more efficient use of space by overlapping certain components and optimizing the layout of data and gate lines, thereby increasing the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If gate driving circuit units and pixel circuit units are arranged in separate areas without overlapping, then the layout is simple and easy to manufacture, but the non-display area increases and display area is reduced
Solution Approach 1:
The patent utilizes vertical stacking to arrange gate driving circuit units and pixel circuit units in different layers (first area and second area) rather than only horizontal placement. This three-dimensional arrangement allows the display area to expand horizontally while circuit units occupy vertical space, effectively resolving the contradiction between display area and layout complexity.
Solution Approach 2:
The patent nests the pixel circuit unit within the vertical space above the gate driving circuit unit. The pixel circuit unit is positioned in the second area directly above the first area containing the gate driving circuit unit, creating a nested configuration that maximizes space utilization and reduces the non-display area.
2Area of stationary object
If the display area is expanded by reducing non-display area, then visual satisfaction is improved, but the arrangement of circuit units becomes more complex
Solution Approach 1:
The patent divides the display device into distinct functional areas: a first area for gate driving circuit units and a second area for pixel circuit units. This segmentation allows each area to be optimized independently for its specific function while maintaining overall manufacturing feasibility through standardized fabrication processes.
Solution Approach 2:
By transitioning from two-dimensional planar arrangement to three-dimensional vertical stacking, the patent expands the display area in the horizontal plane while accommodating circuit units in the vertical dimension. This dimensional change enables larger display areas without proportionally increasing manufacturing complexity.
3Reliability
If gate driving circuit units are spaced apart from each other, then signal interference is reduced, but the non-display area increases
Solution Approach 1:
The patent positions gate driving circuit units in the first area and pixel circuit units in the second area (above them), utilizing the vertical dimension to separate potentially interfering signals. This vertical separation maintains signal integrity while minimizing the horizontal non-display area, as circuit units are stacked rather than spaced apart horizontally.
