Flexible Display Sound Hole Positioning via Bezel Housing Boundary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User terminal apparatuses with flexible displays face challenges in accurately transferring sound during calls and in positioning sound output and input holes without interfering with the flexible display, particularly in securing proximity sensors, camera holes, and light sensors.
Innovation Solution
A user terminal apparatus design featuring a flexible display with a main area and a sub-area that curves to the side, along with a housing that encloses the display, includes strategically positioned sound output holes between the bezel and housing, and a sound input hole, allowing for optimal placement without interfering with the flexible display, ensuring accurate sound transfer during calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the upper surface of the user terminal apparatus is secured as a display area by using the flexible display, then the display area is expanded, but the positioning of sound output holes and other components becomes more difficult
Solution Approach 1:
The patent positions sound output holes at the boundary between the bezel and housing, utilizing the vertical dimension and side surfaces of the device rather than the horizontal display surface. This dimensional shift allows sound holes to be placed in locations that do not interfere with the flexible display's curved surface while still providing effective sound output during calls.
2Measurement precision
If sound output holes are positioned on the upper surface, then sound transfer accuracy is improved, but interference with the flexible display occurs
Solution Approach 1:
The patent introduces the boundary region between the bezel and housing as an intermediary location for sound output holes. This intermediary position serves as a compromise that maintains sound transfer effectiveness while avoiding direct interference with the flexible display's curved surface, as the holes are placed in the transition zone rather than on the display surface itself.
3Adaptability or versatility
If multiple components (proximity sensor, camera hole, light sensor) are positioned on the upper surface, then device functionality is enhanced, but the flexible display design is compromised
Solution Approach 1:
The patent segments the device components into different spatial zones: the flexible display occupies the front and upper curved surfaces for visual interaction, while sound output holes are segregated to the boundary between bezel and housing. This segmentation allows each component type to occupy its optimal location without compromising the flexible display's shape or functionality.
