Groove-Based Hardware Mounting in Flexible OLED Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible OLED display devices face limitations in achieving a full-screen design due to the need for mounting holes for hardware components like cameras and earpieces, which reduce the effective display area and screen ratio.
Innovation Solution
Incorporating a groove in the display screen body to accommodate these components within the display area, with data and power signal wires extending around the groove to connect to a common power bus, allowing for a narrow frame display effect without reducing the screen ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mounting holes are provided outside the display screen body for hardware components, then hardware components can be accommodated, but the screen ratio is reduced and full-screen display cannot be achieved
Solution Approach 1:
The patent applies nesting by placing mounting holes inside the display screen body rather than outside. The display screen body is designed with internal cavities or recesses that can accommodate hardware components like cameras and sensors, allowing these components to be nested within the display structure itself, thereby maintaining the full display area while providing necessary mounting positions.
Solution Approach 2:
The patent transitions from a two-dimensional surface mounting approach to a three-dimensional internal mounting approach. By utilizing the depth and internal volume of the display screen body, the design accommodates hardware components in the third dimension (depth), allowing full front surface utilization for display purposes while still providing mounting capability for necessary components.
2Adaptability or versatility
If mounting holes are provided outside the display screen body, then hardware components can be mounted, but the frame width increases and narrow frame effect cannot be achieved
Solution Approach 1:
Hardware components are nested within the display screen body's internal structure, eliminating the need for external mounting holes that would increase frame width. The display screen body incorporates recesses or cavities that house components like cameras and sensors internally, maintaining a narrow overall frame profile while providing adequate mounting space.
3Ease of manufacture
If the display screen body is made fully continuous without grooves, then manufacturing is simpler, but mounting positions for hardware components cannot be provided
Solution Approach 1:
The display screen body is segmented into functional zones through strategically placed grooves or recesses. These segments create distinct mounting areas within the otherwise continuous display structure, allowing hardware components to be positioned in specific locations without requiring a completely segmented or complex multi-piece construction. The grooves serve as integrated mounting features within a largely monolithic display screen body.
