Integrated Touch Display Electrode Structure for Smaller Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch display devices cannot be reduced in size due to the separation of touch and display functions, which limits their compatibility with the market's demand for smaller and more user-friendly electronic products.
Innovation Solution
Integrating touch and light-emitting components on the same substrate by using a layered structure with conductive parts connected via conductive structures penetrating insulating layers, allowing for the integration of touch and display functions.

Engineering Contradiction Analysis
1Ease of manufacture
If touch panel and display panel are manufactured separately and assembled together, then each component can be optimized independently, but the overall device volume cannot be reduced
Solution Approach 1:
The patent merges the touch panel and display panel into a single integrated structure where the touch sensor components are formed directly on the same substrate as the light-emitting components. The conductive layers, insulating layers, and electrode structures serve dual functions for both touch sensing and display operations, eliminating the need for separate assembly and reducing overall device volume.
Solution Approach 2:
The patent implements multi-functionality by designing conductive layers and electrode structures that simultaneously serve touch sensing functions and display functions. The same substrate, conductive layers, and insulating layers are used for both touch panel operation and light-emitting component operation, allowing one component to perform multiple functions and reducing the number of separate components needed.
2Reliability
If multiple separate components are used for touch and display functions, then functional independence is maintained, but device complexity increases
Solution Approach 1:
The patent combines multiple functional components into a single integrated structure on one substrate. The touch sensor electrodes, conductive layers, and insulating layers are formed simultaneously with the display components, reducing the number of separate parts while maintaining distinct functional zones that preserve operational independence of touch and display functions.
