Display Module Backplane Segmentation for Structural Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monolithic display panels cannot meet the requirements of large display areas, and combining multiple panels poses challenges that affect the overall display effect due to instability in the structure.
Innovation Solution
The use of communication holes in a first backplane and glue filling holes in a second backplane ensures stable fixing of display panels, with air extraction and glue injection through these holes to adhere the panels securely, maintaining structural stability and enhancing the display effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display panels are combined to form a large display area, then the display area is increased, but the structural stability deteriorates
Solution Approach 1:
The backplane is segmented with multiple through-holes (communication holes and glue filling holes) distributed across its surface. This segmentation allows for localized functions (air extraction and glue injection) while maintaining overall structural integrity. The holes are strategically positioned to provide both structural support and functional capabilities without compromising the stability of the combined display panel structure.
Solution Approach 2:
Glue is introduced as an intermediary substance that fills the glue filling holes and bonds the display panels to the backplane structure. This intermediary material provides strong adhesion between the panels and the backplane, ensuring structural stability. The glue acts as a mediator that transfers and distributes mechanical stresses across the joint interfaces, preventing structural failure.

If display panels are fixed using traditional methods, then the structure is simple, but the fixing stability deteriorates
Solution Approach 1:
The backplane is segmented with multiple through-holes (communication holes and glue filling holes) distributed across its surface. This segmentation allows for localized functions (air extraction and glue injection) while maintaining overall structural integrity. The holes are strategically positioned to provide both structural support and functional capabilities without compromising the stability of the combined display panel structure.
Solution Approach 2:
Air extraction is performed through the communication holes to create negative pressure that temporarily holds the display panels against the backplane. This pneumatic mechanism provides stable fixing during the glue injection process and initial bonding phase. The air extraction system uses pressure differentials to achieve reliable panel positioning without complex mechanical clamping structures.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows for the creation of a stable display module with a large display area by securely fixing multiple display panels, ensuring a better overall display effect and structural integrity.
Implementation Method 1
Air extraction is performed on the backplanes at a first air extraction rate through at least part of the communication holes so that the display panels are fixed on the surface of the second backplane
Implementation Method 2
Glue injection is performed on the backplanes through at least part of the communication holes to fill the glue between the first backplane and the second backplane and in the glue filling holes so that the display panels are adhered to the second backplane by the glue in the glue filling holes

AI summary
A display module includes backplanes and at least two display panels disposed on a side of the backplanes. The backplanes include a first backplane and a second backplane disposed opposite to each other and glue between the two. The first backplane includes communication holes extending through the first backplane. The second backplane includes glue filling holes extending through the second backplane. The glue fills the glue filling holes. The display panels are located on the side of the second backplane facing away from the first backplane, overlap the glue filling holes in the thickness direction of the display module, and are adhered to the second backplane by the glue in the glue filling holes.
