Solution Overview
Problem
Current electronic display modules face challenges in optimizing the internal space of portable devices, as existing designs do not adequately accommodate a driving unit and test pads within the limited space, affecting the external appearance and functionality of these devices.
Innovation Solution
A display panel design featuring a non-rectangular extended area with a specific shape that allows for the mounting of a driving unit and test pads, where the extended area has a bottom edge and lateral edges that are curved or straight, providing additional space for components while maintaining a compact form factor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a rectangular extended area is used in conventional display panel designs, then the structure is simple and easy to manufacture, but insufficient space is available for mounting driving units and test pads
Solution Approach 1:
The patent applies asymmetry by changing the extended area from a conventional rectangular shape to a non-rectangular shape with curved lateral edges. This asymmetric design optimizes the distribution of space within the extended area, creating sufficient room for mounting driving units and test pads while maintaining overall structural simplicity and manufacturability.
Solution Approach 2:
The patent utilizes the curvature of lateral edges to effectively expand the usable area within the extended region. By introducing curved boundaries instead of straight lines, the design maximizes the two-dimensional space available for component placement without increasing the overall panel dimensions, thereby accommodating more components in the same footprint.
2Quantity of substance
If the extended area is enlarged to accommodate more components, then more driving units and test pads can be mounted, but the overall display panel size increases
Solution Approach 1:
The patent employs curved lateral edges in the extended area to efficiently utilize available space. The curvature allows for optimized packing of driving units and test pads within the existing panel boundaries, effectively increasing component capacity without expanding the overall display panel area.
Solution Approach 2:
The patent applies local quality by concentrating the non-rectangular curved design specifically in the extended area where components are mounted, while keeping the display area and other critical regions unchanged. This localized modification maximizes component accommodation space without affecting the overall panel dimensions or display quality.
3Area of stationary object
If curved lateral edges are introduced in the extended area, then more space is available for component mounting, but manufacturing complexity increases
Solution Approach 1:
The patent introduces controlled asymmetry through curved lateral edges in the extended area. While the curvature increases design complexity, the asymmetry is applied only to the non-critical extended region, allowing for optimized component placement while maintaining relative simplicity in the manufacturing process for the critical display area.
Solution Approach 2:
The patent applies the curved design locally only to the lateral edges of the extended area, leaving the display area and other critical regions with conventional rectangular boundaries. This localized application of curvature minimizes the impact on manufacturing processes while still achieving the goal of increased component mounting space.

AI summary
A display panel includes a first substrate, a second substrate, a display layer, and a driving unit. The first substrate has a display area, an extended area, and an edge area located between the display area and the extended area. The display layer is positioned between the first and second substrates. The length of a boundary line of the edge area and the extended area is greater than the length of a bottom edge of the extended area that is away from the edge area.
