Display Pixel Antenna Integration for Thinner Bezel Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern computing devices face a tradeoff between antenna performance and design aesthetics due to the space requirements of external antennas, which can be bulky and obstructive, and existing media playback systems consume excessive power and require complex ecosystems for offloading media operations.
Innovation Solution
Integrating multiple antennas and media playback components into the display pixels within the display area, allowing for a thinner bezel design and reduced power consumption by offloading media processing to the display, which includes a radio circuitry, wireless communication controller, memory, and media processing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external antennas are used for wireless communication, then antenna performance is improved, but device aesthetics deteriorate due to bulky and obstructive appearance
Solution Approach 1:
The patent combines multiple antennas and media playback components into the display pixels, integrating wireless communication functionality directly into the display structure. This merging eliminates the need for separate external antennas while maintaining communication performance and improving device aesthetics.
Solution Approach 2:
The patent transitions from traditional external antenna placement to integrating antennas within the display pixel structure, utilizing the two-dimensional pixel array space. This dimensional reorganization allows multiple antennas to be embedded without increasing external device volume or compromising aesthetics.
2Use of energy by moving object
If media playback operations are offloaded to external devices, then power consumption is reduced, but system complexity increases due to required ecosystem compatibility
Solution Approach 1:
The patent merges media playback components (decoder, renderer) directly into the display device, combining wireless communication and media processing functionalities in a single integrated system. This eliminates the need for external media dongles and reduces ecosystem compatibility requirements while enabling local media playback with reduced power consumption.
3Productivity
If multiple antennas are integrated into display pixels, then throughput is enhanced and RF interference is reduced, but manufacturing complexity increases
Solution Approach 1:
The patent makes the display pixels universal by enabling them to serve dual functions: displaying visual information and housing wireless communication antennas. Each pixel structure is designed to accommodate both display elements and antenna elements, allowing the same manufacturing process to produce both functions simultaneously.
Solution Approach 2:
The patent utilizes the unused space within pixel structures (black matrix areas) to position antenna elements, changing the spatial parameters of pixel utilization. This approach integrates antennas without requiring additional pixel area or increasing overall display dimensions, thereby simplifying manufacturing.
4Reliability
If antennas are placed in the display bezel, then wireless communication is enabled, but bezel width must be increased
Solution Approach 1:
The patent moves antenna placement from the one-dimensional bezel boundary to the two-dimensional pixel array area. By utilizing the extensive surface area of display pixels, multiple antennas can be distributed across the display without requiring increased bezel width, thereby maintaining compact device dimensions.
