Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display panels with glass substrates face challenges in minimizing the bezel region width due to potential short-circuits and increased thickness when substrates overlap, limiting the reduction of the non-active area and overall device thickness.
Innovation Solution
A flexible display panel using a plastic substrate with a non-active area featuring cutout portions to accommodate system modules, reducing the bezel region width by inserting modules into these cutouts, and a method involving ultrasonic, wheel cutting, or punching processes to form these cutouts on the plastic substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If substrates are disposed in an overlapping manner to minimize bezel region width, then the width of the bezel region is reduced, but short-circuits may occur and the overall thickness increases
Solution Approach 1:
The patent extracts the driving unit from the display panel substrate and places it on a separate module substrate. The cutout portion in the non-active area of the display panel allows the module substrate to be positioned without overlapping substrates, thereby eliminating short-circuit risks while maintaining minimized bezel width.
Solution Approach 2:
The module substrate containing the driving unit is nested within the cutout portion of the display panel's non-active area. This nesting arrangement allows compact integration without substrate overlap, reducing bezel width while preventing short-circuits through proper spatial separation.
2Length of stationary object
If substrates are disposed in an overlapping manner to minimize bezel region width, then the width of the bezel region is reduced, but the overall thickness of the terminal unit increases
Solution Approach 1:
By extracting the driving unit to a separate module substrate and positioning it in the cutout portion, the patent eliminates the need for substrate overlap. This results in a thinner overall structure while maintaining the minimized bezel width, as components are arranged in parallel rather than stacked.
3Length of stationary object
If the non-active area is reduced to minimize bezel region width, then the bezel region width is minimized, but driving units require space in the non-active area
Solution Approach 1:
The driving unit is extracted from the display panel's non-active area and placed on a separate module substrate. This allows the non-active area to be minimized for bezel reduction, while the driving unit occupies space in the cutout portion outside the main display area.
Solution Approach 2:
The patent repositions the driving unit from the two-dimensional plane of the display panel to a separate module substrate that extends in another dimension. This allows the non-active area to be minimized while still accommodating the driving unit in the cutout portion, effectively utilizing three-dimensional space arrangement.

AI summary
A flexible display panel, and particularly, to a flexible display panel which is bendable, not an existing glass substrate, a fabrication method thereof, and an image display terminal unit using a flexible display panel are provided.In the case of the flexible display panel, the fabrication method, and the image display terminal unit, the flexible display panel is implemented with a plastic substrate, rather than the conventional glass substrate, and a portion of the non-active area of the display panel is cut to form a cutout portion to insert modules of the image display terminal unit into the cutout portion to thus reduce a receiving space of the lower housing, thereby minimizing a width of the bezel region.
