Solution Overview

Problem

Conventional touch panels lack the capability to integrate an antenna function, limiting their ability to transmit or receive wireless signals, which is essential for modern electronic devices with touch-controlled functions.

Innovation Solution

A touch panel structure comprising a touch-controlled unit, a substrate unit with transparent and nontransparent portions, and an antenna unit with an antenna radiation structure disposed on or embedded within the transparent substrate, allowing for the combination of touch functionality with wireless signal transmission and reception capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional touch panels are used, then touch control function is achieved, but antenna function for wireless signal transmission is lacking

Engineering Contradiction:

ImprovefunctionalityVSAvoidstructure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the antenna radiation structure with the transparent substrate of the touch panel, integrating two separate functions (touch control and wireless communication) into a single unified structure. The antenna radiation structure is disposed on or embedded in the transparent substrate, eliminating the need for separate antenna components and achieving functional integration.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The transparent substrate serves dual purposes: it acts as the structural base for the touch panel while simultaneously functioning as the antenna radiation structure for wireless signal transmission. This multi-functional design allows the same component to perform both touch control support and antenna functions, enhancing versatility without adding device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If antenna radiation structure is disposed on transparent substrate, then antenna function is achieved, but transparency and touch sensitivity may be affected

Engineering Contradiction:

Improveantenna functionVSAvoidtransparency

Core Design Contradiction:

Adaptability or versatilityVSIllumination intensity

Solution Approach 1:

The antenna radiation structure is strategically disposed on or embedded in specific regions of the transparent substrate, allowing different areas to have different functions. The transparent portion maintains its optical properties for display visibility, while the antenna radiation structure provides wireless communication functionality in specific zones without compromising overall transparency.

Inventive Principle:

Principle #3Local quality

AI summary

A touch structure having an antenna function includes a substrate unit and an antenna unit. The substrate unit has a touch surface on the top surface thereof for an external object to touch in order to operate a touch-controlled module. The substrate unit includes at least one transparent substrate having at least one transparent portion and at least one nontransparent portion disposed around the transparent portion and combined with the transparent portion, the transparent portion has an image-viewing area on the top surface thereof, and the nontransparent portion has a non-image-viewing area on the top surface thereof. The antenna unit includes at least one antenna radiation structure disposed on the transparent substrate or embedded in the transparent substrate, and the layout of the antenna radiation structure shows an antenna radiation pattern having a predetermined operation band.
