Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antenna layouts in terminal devices face challenges with insufficient clearance space, leading to poor communication quality due to the increasing screen-to-body ratio, which affects the performance and efficiency of signal reception and transmission.
Innovation Solution
An array substrate is integrated with an antenna, where the antenna is positioned above the screen, allowing for increased clearance space and improved communication quality by isolating it from the component layer using a gap or baffle plate, and utilizing multiple metal and dielectric laminates to form thin film transistors and enhance signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the antenna is integrated into the array substrate with the component layer, then the terminal device achieves miniaturization and high integration degree, but the antenna clearance space is reduced leading to poor communication quality
Solution Approach 1:
The array substrate is divided into distinct functional regions: a first region for the component layer containing thin film transistors and a second region for the antenna. This spatial segmentation allows both the display control components and antenna to coexist on the same substrate without interfering with each other, achieving high integration while maintaining adequate antenna clearance space for reliable communication
Solution Approach 2:
The patent utilizes the planar dimension of the substrate to separate components rather than stacking them vertically. By arranging the component layer and antenna in adjacent planar regions rather than overlapping layers, the design achieves high integration density while preserving the antenna's required clearance space in the vertical dimension, thus maintaining communication quality
2Reliability
If the antenna is positioned away from the component layer with a gap, then the communication quality is improved by reducing interference, but the device size increases reducing miniaturization
Solution Approach 1:
The antenna and component layer are merged onto the same array substrate rather than being separate components. This consolidation reduces the overall device footprint while the strategic positioning creates sufficient clearance between them, achieving both miniaturization and maintained communication quality through reduced interference
3Adaptability or versatility
If multiple metal and dielectric laminates are used to form thin film transistors, then the component layer functionality is enhanced, but the manufacturing process complexity increases
Solution Approach 1:
The same array substrate serves multiple functions: it acts as both the base for the component layer with thin film transistors (formed through multiple metal and dielectric laminates) and as the mounting substrate for the antenna. This multi-functionality enhances component layer capabilities while avoiding the need for separate manufacturing processes, thus not increasing overall manufacturing complexity
