Innovation Solution
A display device with a flexible display panel, driving chip, main flexible circuit board, touch layer, and touch flexible circuit board configuration that includes a spacer to create a larger clearance zone for antenna placement, allowing for improved antenna performance and increased antenna count without altering the phone's overall size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the screen-to-body ratio is increased to achieve a full-screen display, then the visual experience and appearance are improved, but the available space for antenna placement is reduced
Solution Approach 1:
The patent introduces a spacer that creates a thickness direction dimension, allowing antennas to be placed in the Z-direction (above and below the display panel) rather than only in the planar X-Y directions. This vertical dimensionality change provides additional antenna placement space without reducing the screen-to-body ratio in the planar view.
Solution Approach 2:
The patent nests multiple antennas within the thickness of the display device by positioning them at different heights along the Z-axis. The spacer creates layered structures where antennas can be nested above and below the display panel, maximizing space utilization in the vertical dimension.
2Reliability
If multiple antennas are added to support multi-band signal reception, then the antenna performance and signal reception capability are improved, but the device complexity and space requirements increase
Solution Approach 1:
The patent segments the antenna system into multiple independent antenna elements positioned at different locations and orientations. Each antenna can be independently designed and tuned for specific frequency bands, allowing complex multi-band reception to be achieved through modular segmentation rather than a single complex antenna structure.
Solution Approach 2:
By utilizing the thickness direction (Z-axis) for antenna placement, the patent distributes multiple antennas vertically rather than horizontally. This dimensional redistribution reduces planar complexity and allows multiple antennas to coexist without increasing the device's footprint, thereby managing complexity while maintaining signal reception capability.
3Shape
If the antenna design is optimized for full-screen configuration, then the visual appearance is improved, but the antenna performance and signal reception are affected
Solution Approach 1:
The patent moves antenna elements from the planar display surface into the vertical dimension using spacers. This separation allows the display surface to maintain its full-screen appearance without antenna obstructions, while antennas positioned in the Z-direction can operate independently with optimized performance for their specific locations and orientations.
Solution Approach 2:
The patent applies local quality by positioning different antenna elements at specific locations and orientations tailored to their functional requirements. Each antenna can be locally optimized for its intended frequency band and reception pattern, while the overall display maintains its full-screen aesthetic quality.
