Side-Mounted Driving Units Reduce Non-Display Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices have a significant non-display area due to the placement of driving units and signal lines on the top or bottom surfaces, which limits the display area and reduces the overall efficiency of the panel.
Innovation Solution
The display device incorporates a structure where the tape carrier package and control signal lines are disposed on the side surfaces of the display panel, reducing the non-display area and increasing the display area by relocating the gate and data driving units and their corresponding signal lines to the side surfaces.

Engineering Contradiction Analysis
1Area of stationary object
If driving units and signal lines are disposed on the top or bottom surfaces of the display panel, then the electrical connection and signal transmission are achieved, but the non-display area increases and the display area decreases
Solution Approach 1:
The patent relocates the driving units and signal lines from the traditional top/bottom surface planes to the side surfaces of the display panel. This dimensional transition moves components from the 2D plane of the display surface to the 3D side edges, effectively utilizing previously unused spatial dimensions to reduce the non-display area on the main surface.
Solution Approach 2:
The driving units and control signal lines are extracted from the main display surface area and relocated to the side surfaces. This extraction removes the problematic elements that consume display area from the primary functional region, allowing the display area to be maximized while maintaining electrical connection functionality.
2Productivity
If driving units are mounted on the display panel surface, then electrical connection is achieved, but the non-display area increases reducing panel efficiency
Solution Approach 1:
The patent utilizes the side surfaces of the display panel as a separate dimensional space for mounting driving units and routing signal lines. This approach transforms the problem from a 2D surface area constraint to a 3D spatial utilization solution, thereby increasing panel efficiency by maximizing the display area on the front surface.
Solution Approach 2:
The patent segments the display panel structure into distinct functional zones: the front surface dedicated to display area and the side surfaces dedicated to driving units and signal routing. This segmentation allows each zone to optimize its specific function without interfering with the other, thereby maximizing overall panel efficiency.
