Solution Overview

Problem

Existing touch display devices often experience misoperations due to the lack of control over touch functions, particularly in devices with narrow frames where accidental touches are common, leading to reduced user experience.

Innovation Solution

A touch structure comprising intersecting first and second electrodes with switch units that enable or disable touch functions in specific regions by controlling connection and disconnection between electrodes and signal transmission lines, allowing for selective enablement or disablement of touch functions based on user demand.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the touch function is enabled in the whole touch display panel, then the user can operate the device freely, but accidental touches cause misoperations and reduce user experience

Engineering Contradiction:

Improvetouch function availabilityVSAvoidoperation accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The touch display panel is divided into multiple independent touch control regions, each with its own switch unit. This allows selective enabling or disabling of touch functions in specific regions without affecting other areas, thereby maintaining overall adaptability while preventing accidental touches in unwanted regions.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each touch control region is equipped with a switch unit that can dynamically change the state of electrodes in that region between conductive and non-conductive. This dynamic control allows the touch function to be adaptively enabled or disabled in real-time based on user needs, resolving the contradiction between universal availability and preventing misoperations.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If switch units are added to each touch control region, then touch function can be selectively controlled, but the device structure becomes more complex

Engineering Contradiction:

Improveselective touch controlVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The switch unit integrates multiple functions including signal transmission control and electrode state switching into a single component. By merging these functions, the patent reduces the number of separate components needed, thereby controlling structural complexity while achieving selective touch control capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The switch unit is designed as a multi-functional component that can control multiple electrodes and serve multiple touch control regions. This universal design allows one switch unit to perform multiple functions, reducing overall device complexity while maintaining selective control capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If electrodes are made closable to prevent accidental touches, then misoperations are reduced, but the touch control flexibility is limited

Engineering Contradiction:

Improvemisoperation preventionVSAvoidtouch control flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The electrodes are designed with switch units that can dynamically change their state between conductive and non-conductive. This dynamic capability allows the electrodes to be closable when needed to prevent misoperations, while remaining fully functional when touch control flexibility is required, thus resolving the contradiction between reliability and adaptability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Each touch control region is equipped with its own switch unit that can independently control the state of its electrodes. This self-service design allows each region to autonomously enable or disable touch functions based on local requirements, maintaining overall system flexibility while providing misoperation prevention in specific areas.

Inventive Principle:

Principle #25Self-service

AI summary

A touch structure, touch display panel and touch display device are disclosed. The touch structure comprises multiple first electrodes and multiple second electrodes arranged to intersect with and insulate from the first electrodes. The first and second electrodes are connected with respective signal transmission lines which transmits a touch signal to the corresponding first or second electrode. At least one electrode in a set of the first and second electrodes is a closable electrode, at least a part of which is a closable part. A switch unit is arranged between the closable part and the corresponding signal transmission line to control connection and disconnection therebetween. With the present invention, by arranging the switch unit between the closable part and the corresponding signal transmission line to control the connection and disconnection therebetween, the touch function in the region corresponding to the closable part can be enabled or disabled.
