Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display device assembly methods face challenges in achieving reliable and easy assembly with a reduced bezel region, as the peripheral region is often affected by the coupling of electronic circuits, leading to increased complexity and potential instability.
Innovation Solution
The display device incorporates an inclined surface on the first base substrate, allowing the electronic circuit to be coupled on this surface, which reduces the bezel region and prevents the electronic circuit from contacting external parts, thereby enabling stable and easy assembly by using a pad electrode that extends along the inclined surface to contact the signal lines and the rear surface of the substrate.

1Area of stationary object
If the electronic circuit is coupled on the peripheral region of the display panel, then the display function is achieved, but the bezel region increases and assembly complexity increases
Solution Approach 1:
The patent moves the electronic circuit from the traditional planar peripheral region to a three-dimensional inclined surface on the side of the display panel. This dimensional transition allows the circuit to be positioned on the first side surface that extends in a direction crossing the display panel's main plane, effectively utilizing vertical space and reducing the horizontal bezel area while maintaining circuit functionality and simplifying assembly operations.
Solution Approach 2:
The display panel is divided into distinct functional regions: the main display area and the inclined side surface area. This segmentation allows the electronic circuit to be independently positioned on the inclined surface, separating it from the peripheral region and enabling independent design and assembly of different components, thereby reducing overall assembly complexity.
2Reliability
If the pad electrode extends along the inclined surface to contact signal lines, then electrical connection is achieved, but manufacturing complexity increases
Solution Approach 1:
The pad electrode's geometric parameters are optimized to match the inclined surface's angle and dimensions. By adjusting the electrode's shape, size, and orientation to correspond with the inclined surface parameters, the patent achieves reliable electrical contact while streamlining the manufacturing process through parameter-based design rather than complex structural modifications.
