Foldable Display Panel Layout for Circuit Board Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices face challenges in providing sufficient space for circuit components due to bending or folding, leading to insufficient space for circuit boards and associated elements.
Innovation Solution
The display device incorporates a display panel with a first portion extending from the non-display area, bent and connected to a circuit board, where the second portion of the display panel is narrower than the first, allowing efficient space utilization and integration of circuit elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is bent or folded to achieve flexible form, then the flexibility and portability are improved, but the space for circuit board and components becomes insufficient
Solution Approach 1:
The display panel is segmented into a first portion and a second portion, where the first portion has a greater width than the second portion. This segmentation allows the narrower second portion to accommodate the circuit board while the broader first portion provides the necessary display area, resolving the space conflict in flexible display devices.
Solution Approach 2:
Different portions of the display panel are given different widths to serve different functions. The first portion is wider to provide display area, while the second portion is narrower to accommodate circuit components. This local differentiation of quality (width) allows both display functionality and circuit integration in a flexible form factor.
2Adaptability or versatility
If the circuit board area is reduced to accommodate bending, then the flexibility is improved, but the space for circuit components becomes insufficient
Solution Approach 1:
The display panel structure is segmented into portions with different widths. The second portion is specifically designed with a narrower width that still provides adequate space for circuit components while enabling the overall flexibility of the display device when bent or folded.
3Ease of manufacture
If the display panel width is uniform, then the manufacturing is simplified, but the space utilization for circuit integration is inefficient
Solution Approach 1:
Rather than using a uniform width throughout, the display panel is segmented into portions with different widths. This segmentation optimizes space utilization by creating a narrower second portion for circuit integration while maintaining adequate display area in the first portion, without significantly complicating the manufacturing process.
Solution Approach 2:
The display panel employs local quality variation where different portions have different widths tailored to their specific functions. This allows efficient space utilization for circuit integration in the second portion while maintaining manufacturing feasibility through a relatively simple width variation.

AI summary
A display device includes a display panel including a display area and a non-display area around the display area, where the display panel includes a display surface on which an image from the display area is displayed, and a rear surface opposite to the display surface, and a circuit board connected to the display panel. The display panel further includes a first portion extending from the non-display area and bent, and a second portion extending from the first portion in a first direction to face the rear surface of the display panel, protruding from the first portion in the first direction, and connected to the circuit board, the first portion of the display panel has a first width in a second direction crossing the first direction, and the second portion of the display panel has a second width less than the first width in the second direction.
