Folded Display Module NFC Layout for Stronger Signal Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display modules with near field communication structures suffer from insufficient signal quantity, leading to poor short-range wireless communication performance.
Innovation Solution
The display module design includes a near field communication structure located on the backlight side of the display portion, with overlapping orthographic projections with the bonding portion, and utilizes a composite film and double-sided adhesive to enhance the area and performance of the near field communication structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the near field communication structure is placed on the display module, then short-range wireless communication function is provided, but the signal quantity is insufficient
Solution Approach 1:
The patent extends the near field communication structure from a two-dimensional planar configuration to a three-dimensional configuration by making it overlap with the bonding portion in the vertical direction. This dimensional extension increases the effective area of the near field communication structure, thereby improving signal quantity while maintaining communication functionality
2Quantity of substance
If the area of near field communication structure is increased, then signal quantity is improved, but the device structure becomes more complex
Solution Approach 1:
The patent merges the near field communication structure with the bonding portion by positioning them to overlap. This integration allows the bonding portion to serve dual purposes: structural bonding function and near field communication function, thereby increasing signal quantity without adding separate components or increasing device complexity

AI summary
A display module and a display device. The display module comprises a display panel (5) and a near field communication structure (9); the display panel (5) comprises a display portion (13), a bent portion (14), and a binding potion (15) which are connected in sequence; the bent portion (14) is bent to a backlight side (23) of the display portion (13); the near field communication structure (9) is located on the backlight side (23) of the display potion (13); the display portion (13), the near field communication structure (9), and the binding portion (15) are sequentially arranged in a direction perpendicular to the display portion (13); and the orthographic projection (B) of the near field communication structure (9) on the display portion (13) at least partially overlaps the orthographic projection (A) of the binding portion (15) on the display portion (13). By increasing the area of the near field communication structure (9), the semaphore of the near field communication structure (9) is improved, and the near field communication performance of the display module is ensured.
