Display Module Antenna Integration for Compact 5G Layouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of antennas in 5G communication devices, such as smartphones, leads to insufficient space for antenna placement, resulting in reduced efficiency and larger device sizes due to the need for long antenna wiring and pads in non-display areas.
Innovation Solution
A display module with a carrier integrated first antennas, allowing additional antennas to be added without increasing volume, by directly connecting them to external antennas through exposed connecting points on the carrier's side surface, reducing the need for wiring and pads in non-display areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of antennas is increased to meet 5G communication requirements, then the antenna coverage and communication capability are improved, but the space inside the mobile phone becomes insufficient and the device complexity increases
Solution Approach 1:
The patent merges the antenna structure with the display module by integrating the antenna into the non-display area of the display panel. This combination allows the antenna to share the display module's space, eliminating the need for separate antenna housing space and resolving the contradiction between increasing antenna count and maintaining compact device volume.
Solution Approach 2:
The patent utilizes the non-display area of the display panel as an additional spatial dimension for antenna placement. By transitioning from traditional side-mounted or bottom-mounted antenna positions to integrating antennas within the display module's non-display area, the design effectively adds a new spatial dimension for antenna arrangement, enabling more antennas without increasing overall device footprint.
2Reliability
If traditional antenna wiring and pads are arranged in the non-display area, then the antennas can be electrically connected, but the non-display area size increases and signal transmission path is lengthened
Solution Approach 1:
The patent merges the antenna wiring and connection pads directly into the non-display area of the display panel, eliminating the need for separate wiring paths. The antenna is electrically connected to the terminal through conductive structures formed within the display panel's non-display area, thereby reducing the required non-display area size while maintaining reliable electrical connection.
Solution Approach 2:
The patent introduces a conductor layer within the display panel structure that serves as an intermediary transmission path for antenna signals. This conductor layer is integrated into the display panel's internal structure, providing a direct and short transmission path between the antenna and terminal connection points, thereby reducing signal loss and eliminating the need for long external wiring paths.

AI summary
A display module and an electronic device. The display module includes a display area and a non-display area arranged around at least a part of the display area. The display module includes: a carrier including a first surface and a second surface arranged oppositely and a side surface located between the first surface and the second surface and in the non-display area; and a first antenna including a first body and at least one connecting point connected with the first body, in which the first body is arranged in the carrier, and the connecting point is exposed on the side surface for being electrically connecting with a second antenna located outside the carrier.
