Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The sensing modules detect the proximity and orientation of adjacent display devices, providing feedback signals to the control circuits. This enables automatic adjustment of display patterns and alignment, ensuring reliable integration and communication between spliced devices without manual intervention.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Each display device autonomously detects its position relative to adjacent devices using onboard sensing modules and automatically configures its display pattern accordingly. The devices self-align and establish communication without requiring external configuration, improving integration effectiveness.

Inventive Principle:
Principle #25Self-service

2Reliability

If sensing modules are added to detect proximity of adjacent displays, then the alignment and communication capability are improved, but the device complexity increases

Engineering Contradiction:

Solution Approach 1:

The sensing modules serve multiple functions: detecting proximity, determining orientation, and triggering appropriate display patterns. This multi-functionality reduces the need for separate components and minimizes overall device complexity while improving alignment and communication capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The sensing modules and control circuits are integrated within each display device, combining detection and control functions into a unified system. This merging reduces the number of external components and simplifies the overall device architecture while enhancing alignment capability.

AI summary

A multi-screen splicing structure (10) has a plurality of display devices (100A, 100B). Each display device (100A, 100B) has a display panel (110A, 100B), a sensing module (120A, 120B), and a control circuit (130A, 130B). When the sensing module (120A, 120B) of a display device (100A, 100B) senses the sensing module (120B, 120C) of another display device (100B, 100A), the control circuit (130A, 130B) determines which side of the display panel (110A, 100B) is adjacent to the proximate display device (100B, 100A) according to the sensing states of a plurality of sensors (122A, 122B) of the sensing module (120A, 120B). The control circuit (130A, 130B) controls a portion of pixels (112A, 112B) adjacent to the proximate display device (100B, 100A) to display a pattern (160A, 160B).
