Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch display panels require separate antenna components integrated in a middle frame, occupying internal space and hindering the reduction of device thickness and increasing assembly complexity and costs.
Innovation Solution
A touch display panel with a functional composite layer that integrates both touch and antenna patterns in the same layer, allowing for electrical insulation and efficient space utilization, eliminating the need for a separate antenna module in the middle frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If antenna components are integrated in a middle frame, then antenna function is achieved, but internal space is occupied and device thickness cannot be reduced
Solution Approach 1:
The patent merges the antenna pattern with the touch pattern into a single functional composite layer. The antenna pattern is formed using the same conductive material and deposition process as the touch pattern, eliminating the need for a separate middle frame structure. This integration achieves both antenna function and space efficiency simultaneously.
Solution Approach 2:
The functional composite layer serves multiple functions: it provides touch sensing capability through the touch pattern while simultaneously providing antenna functionality through the antenna pattern. This multi-functional design eliminates the need for separate dedicated antenna structures, thereby reducing overall device volume.
2Adaptability or versatility
If antenna components are integrated in a middle frame, then antenna function is achieved, but assembly steps and material costs increase
Solution Approach 1:
The patent combines the manufacturing processes for the touch pattern and antenna pattern into a single sequence. Both patterns are formed in the same functional composite layer using the same conductive material deposition steps, eliminating the need for separate assembly operations for antenna components.
Solution Approach 2:
The patent extracts the antenna function from the traditional middle frame structure and integrates it directly into the functional composite layer. This extraction eliminates the need for separate antenna modules and their associated assembly steps, simplifying the overall manufacturing process.
3Adaptability or versatility
If antenna components are integrated in a middle frame, then antenna function is achieved, but device thinness is hindered
Solution Approach 1:
The patent merges the antenna pattern with the touch pattern in the same functional composite layer, eliminating the need for a separate middle frame structure that would add thickness. The antenna pattern is formed as part of the standard layer stacking sequence, maintaining device thinness while providing antenna functionality.

AI summary
The present application provides a touch display panel and a display device. The touch display device includes a functional composite layer. The functional composite layer includes a touch pattern area and an antenna pattern area. A touch pattern is arranged in the touch pattern area, and the antenna pattern is arranged in the antenna pattern area. The antenna pattern and the touch pattern are arranged in a same layer, and the antenna pattern is electrically insulated from the touch pattern, so that the present application avoids placing the antenna pattern in a middle frame of the display device and improves lightness and thinness of the display device.
