Here’s PatSnap Eureka !
Summary
Problems
Conventional capacitive touch panels have high manufacturing costs and increased thickness due to complex processes and the use of double-board structures with expensive transparent conductive substrates, which are difficult to recycle and result in material waste.
Innovation solutions
A capacitive touch panel design featuring a single conductive layer coated on a transparent substrate with a protection layer, reducing material waste and manufacturing complexity, and incorporating a flexible circuit board to simplify the structure and lower costs.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If double-board touch panel structure with multiple transparent conductive substrates is used, then touch control functionality is achieved, but manufacturing cost increases and thickness increases
Why choose this principle:
The patent merges multiple separate transparent conductive substrates into a single integrated substrate structure. Instead of using multiple separate boards that require complex assembly, the invention integrates all conductive layers and functional elements onto one substrate, thereby simplifying the manufacturing process and reducing overall device complexity while maintaining touch control functionality.
Principle concept:
If double-board touch panel structure with multiple transparent conductive substrates is used, then touch control functionality is achieved, but manufacturing cost increases and thickness increases
Why choose this principle:
The patent segments the touch panel into distinct functional layers (conductive layer, insulating layer, protective layer) on a single substrate. This segmentation allows each layer to be optimized independently for its specific function while avoiding the complexity of assembling multiple separate substrates. The layered structure enables simplified manufacturing compared to the double-board approach.

Abstract
A capacitive touch panel unit includes a transparent substrate, a conductive layer and a protection layer. The transparent substrate has a first side and a second side opposite to the first side. The conductive layer is disposed on the second side. The protection layer is correspondingly attached to one side of the conductive layer, which side is opposite to the transparent substrate. By means of the design of the capacitive touch panel unit, the number of the conductive layer is reduced to lower the manufacturing cost and reduce the total thickness.
