Display Panel Antenna Layout for Thin 5G High Screen-to-Body Designs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of antennas required for 5G communication in mobile devices, combined with the trend towards thinner and smaller designs, leads to insufficient space for antennas, resulting in reduced communication efficiency and interference issues.
Innovation Solution
A display panel design with separate first and second display areas, where the first area houses a first antenna and the second area integrates a second antenna and touch electrodes, allowing for efficient antenna integration without interference, and a high screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of antennas is increased to support 5G communication, then communication efficiency is improved, but the internal space is consumed and the device becomes thicker
Solution Approach 1:
The patent merges the antenna function with the display panel by integrating antennas into the display area. The display panel serves dual purposes: displaying visual information and housing communication antennas, thereby eliminating the need for separate antenna spaces and reducing overall device volume.
Solution Approach 2:
The display panel is designed to perform multiple functions simultaneously: it acts as both a display device and an antenna carrier. This multi-functionality allows the same structural component to support both visual output and wireless communication, optimizing space utilization.
2Volume of moving object
If antennas are placed in the display area, then space is saved, but the risk of mis-touch interference increases
Solution Approach 1:
The display area is segmented into distinct functional zones: a first area dedicated to antenna placement and a second area for touch-sensitive display elements. This spatial segmentation allows both antenna and touch functions to coexist without interference, as each zone operates independently.
Solution Approach 2:
Different regions of the display panel are assigned different functional qualities: the first area is optimized for antenna performance with appropriate electromagnetic characteristics, while the second area maintains full touch sensitivity. This local differentiation ensures that antenna placement does not compromise touch functionality.
3Shape
If the frame is made narrower to achieve a thinner design, then aesthetic appearance is improved, but the space for antennas is reduced
Solution Approach 1:
The patent transitions antenna placement from the traditional side-frame dimension to the display area dimension. By utilizing the display region for antenna housing, the design achieves narrow frames without compromising antenna space, as antennas are now accommodated within the display matrix rather than in peripheral frames.

AI summary
A display panel and a display apparatus. The display panel includes a first display area and a second display area including a first area and at least one second area, a first antenna is arranged in the first area, a second antenna is arranged in the at least one second area. The display panel further includes a plurality of touch electrodes arranged in the first display area and the at least one second area. In the display panel and the display apparatus, first antennas and second antennas are integrated in the second display area of the display panel, so that both a display function and an antenna function can be achieved for the second display area, which is beneficial for making a product light and thin and making a product have a high screen-to-body ratio.
