Bent Display Panel with Narrower Section for Circuit Board Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices face challenges in providing sufficient space for circuit boards due to bending or folding, leading to insufficient space for components.
Innovation Solution
A display device design where the display panel includes a first portion extending from the non-display area, bent, and a second portion extending to face the rear surface of the panel, connected to the circuit board, with the second portion having a narrower width than the first, allowing for efficient use of space on the circuit board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is bent to provide flexibility, then the device can be folded or transformed into curve shapes, but the space available for the circuit board and components becomes insufficient
Solution Approach 1:
The display panel is segmented into multiple portions: a first portion extending from the non-display area, a second portion extending in a first direction to face the rear surface, and a third portion extending in a second direction. This segmentation allows the circuit board to be positioned on the third portion while maintaining flexibility through the bent configuration of the first and second portions.
Solution Approach 2:
The display panel is configured to extend in multiple directions (first direction and second direction) from the non-display area, creating a three-dimensional arrangement. This dimensional change allows the circuit board to be positioned in a direction away from the display surface, effectively utilizing space that would otherwise be unavailable in a flat configuration.
2Area of stationary object
If the display panel structure is modified to accommodate the circuit board, then space utilization improves, but the device complexity increases
Solution Approach 1:
The display panel serves multiple functions: it acts as both the display surface and the structural support for the circuit board. The first, second, and third portions of the display panel collectively provide both the necessary flexibility and the space for circuit board mounting, eliminating the need for separate support structures.
Solution Approach 2:
The display panel utilizes its inherent flexibility to create a bent configuration that accommodates the circuit board. By bending the first and second portions of the display panel, the structure naturally creates space for the circuit board without requiring additional rigid support elements, thus avoiding increased device complexity.

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 is 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.
