Display Module Positioning Elements for Touch Panel Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly process of touch panels and display modules is complex and costly due to the need for dedicated assembly fixtures that must match the size of the touch display, leading to inefficiencies and increased costs.
Innovation Solution
Incorporating first and second positioning elements on the display module, which serve as reference points for aligning the touch panel, allowing for accurate alignment and attachment without the need for additional assembly fixtures, thereby simplifying the assembly process and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a dedicated assembly fixture is used for each touch display size, then alignment precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts the alignment reference function from the complex assembly fixture and concentrates it into simple positioning protrusions integrated into the display module. This eliminates the need for separate, size-matched assembly fixtures while maintaining alignment precision through the positioning protrusions that engage with corresponding recesses in the touch panel.
Solution Approach 2:
The display module body serves multiple functions: it acts as both the structural housing and the alignment reference through its integrated positioning protrusions. This universal design allows the same display module structure to be used across different touch display sizes without requiring dedicated assembly fixtures for each size.
2Manufacturing precision
If a dedicated assembly fixture is used for each touch display size, then alignment precision is improved, but manufacturing cost increases
Solution Approach 1:
The alignment reference function is extracted from expensive, size-specific assembly fixtures and implemented through simple positioning protrusions that are integral to the display module. This dramatically reduces manufacturing cost while maintaining alignment precision.
Solution Approach 2:
The positioning protrusions are simple, inexpensive features integrated into the display module that replace costly, dedicated assembly fixtures. These positioning features are easy to manufacture and eliminate the need for expensive, size-matched tooling.
3Manufacturing precision
If an assembly fixture is used, then alignment is improved, but assembly process complexity increases
Solution Approach 1:
The alignment reference function is extracted from the assembly fixture and integrated directly into the display module through positioning protrusions. This simplifies the assembly process by eliminating the need for separate fixtures while maintaining precise alignment through the engaging positioning features.
Solution Approach 2:
The display module provides its own alignment reference through integrated positioning protrusions, eliminating the need for external assembly fixtures. The positioning protrusions and recesses work together to automatically ensure proper alignment during assembly.
4Manufacturing precision
If size-matched assembly fixtures are used, then alignment precision is improved, but productivity decreases
Solution Approach 1:
The display module body serves as a universal alignment reference through its positioning protrusions, eliminating the need for size-matched assembly fixtures. This universal design speeds up the assembly process while maintaining precision across different touch display sizes.
Solution Approach 2:
The alignment reference function is extracted from time-consuming, size-specific fixtures and implemented through simple, integrated positioning protrusions. This reduces assembly time and increases productivity while maintaining alignment precision.

AI summary
An electro-optical apparatus including a display module and a touch panel is provided. The display module includes a body, at least a first positioning element, and at least a second positioning element. The body has a display surface and a bottom surface opposite to the display surface. The first positioning element and the second positioning element are connected to the body. The first positioning element is disposed on a first side of the body and the second positioning element is disposed on a second side of the body that is adjacent to the first side. The first positioning element and the second positioning element protrude from the display surface in a direction away from the bottom surface. The touch panel is disposed on the display surface of the body, and edges of the touch panel abut against the first positioning element and the second positioning element.
