Display Panel Microphone Layout for Slim Bezel Voice Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices face challenges in integrating microphones due to slim and bezel-less designs, leading to degraded sound collecting performance as the microphone's height or location differs from the user's utterance point.
Innovation Solution
The display panel is equipped with a microphone installed at the user's utterance level, eliminating the need for additional space or structure by incorporating it behind the image display area, utilizing micro electro mechanical system (MEMS) microphones and strategically placed holes in the substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the microphone is arranged in the bezel or as a separate module on the outer edge, then the device structure is simple, but the sound collecting performance is degraded due to height or location difference from user's utterance point
Solution Approach 1:
The patent merges the microphone with the display panel by installing it behind the image display area at the user's utterance level. This integration eliminates the need for separate microphone modules or bezel arrangements, achieving both improved sound collection (microphone is at optimal height) and simplified device structure (no extra components needed)
Solution Approach 2:
The patent moves the microphone from traditional horizontal placement (in bezel or on outer edge) to a vertical dimension behind the display panel at the user's utterance level. This dimensional change allows the microphone to be positioned at the optimal height for sound collection while being integrated into the panel structure
2Reliability
If the microphone is installed in the bezel of a large display device, then the device can accommodate the microphone, but the sound collecting performance is degraded due to location difference from user's utterance point
Solution Approach 1:
The patent relocates the microphone from the horizontal bezel dimension to the vertical dimension behind the display panel. By positioning it at the user's utterance level in the depth direction, the microphone achieves optimal sound collection without requiring any increase in bezel width
3Shape
If the display device is designed with slim and narrow bezels, then the device achieves a modern aesthetic design, but there is no space to arrange the microphone in the bezel
Solution Approach 1:
The patent relocates the microphone from the horizontal bezel dimension to the vertical dimension behind the display panel at the user's utterance level. This allows the bezel to remain slim and narrow while providing adequate space for microphone installation through the depth dimension of the panel
Solution Approach 2:
The patent integrates the microphone installation into the display panel structure itself, combining the panel and microphone into a single unified structure. This eliminates the need for separate bezel space while maintaining slim bezel design
