Display Device with Bendable Area and Support Film Gap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in reducing thickness and manufacturing costs while maintaining environmental reliability and preventing defects such as cracks and driving chip issues.
Innovation Solution
The display device incorporates a display panel with a first area for the display, a second area for non-display components, and a bendable third area with a gap between the panel bottom cover and the support film. This configuration reduces stacked structures in the display area, lowers manufacturing costs, and enhances environmental reliability by positioning the support film in the non-display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a support film is disposed in the first area (display area) to protect the display panel, then environmental reliability is improved, but the overall thickness increases due to stacked structures
Solution Approach 1:
The patent divides the display panel into three distinct areas: a first area (display area), a second area (non-display area), and a bendable third area. The support film is selectively disposed only in the second area, separating the protective function from the display area to reduce thickness while maintaining reliability where needed.
Solution Approach 2:
The support film is repositioned from the traditional display area to the non-display area, utilizing unused spatial dimension. This dimensional relocation allows the protective function to be maintained without adding thickness to the critical display region.
2Reliability
If multiple stacked structures are used in the first area to enhance protection, then reliability is improved, but manufacturing complexity and costs increase
Solution Approach 1:
The support film structure is extracted from the first area and relocated to the second area. This extraction eliminates the need for complex stacked structures in the display area, simplifying manufacturing processes and reducing costs while maintaining protective functionality in the non-display area.
Solution Approach 2:
The patent applies different structural qualities to different areas: the first area maintains a simplified structure for display purposes, while the second area contains the support film for protection. This localized quality assignment optimizes both manufacturing simplicity and reliability where needed.
3Length of stationary object
If the display panel is made thinner to reduce device thickness, then portability is improved, but structural stability and resistance to defects decrease
Solution Approach 1:
The support film acts as an intermediary structural element positioned in the second area. It provides the necessary structural stability and protection against defects without being located in the thin display area, thus maintaining overall thinness while ensuring structural integrity through the intermediary support structure.

Function Achieved in This Case
The solution effectively reduces the overall thickness of the display device, lowers manufacturing costs, and improves environmental reliability by preventing defects and ensuring stable support for the display panel.
Implementation Method 1
the adhesive member may comprise a light absorbing material that bonds the heat dissipation member to the lower surface of the display panel and to absorb light irradiated from outside
Implementation Method 2
a bonding layer bonding the support film to the lower surface of the display panel
Implementation Method 3
a heat dissipation member bonded to the lower surface of the display panel in the first area and dissipating heat from the display panel
