Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple LED transparent screens are spliced into one large display apparatus, then the display area is increased, but the connection between adjacent screens has poor transparency
Solution Approach 1:
The patent extracts the connecting structure from the traditional opaque frame and relocates it to the edges of the circuit board, using transparent connecting columns instead of opaque frames. This separation allows the majority of the screen area to remain transparent while providing dedicated connection points at the edges.
Solution Approach 2:
The patent applies different transparency properties to different parts of the screen: the circuit board has transparent portions for light transmission and mounting portions with LED lamp beads for display, while the connecting columns provide structural connection with minimal visual obstruction. This local differentiation resolves the contradiction between connection strength and overall transparency.
2Strength
If connecting structures are added to join adjacent screens, then the mechanical strength is improved, but the transparency is reduced
Solution Approach 1:
The patent uses thin, transparent connecting columns made of transparent material that provide mechanical connection while minimizing visual obstruction. These thin film-like structures maintain structural integrity without significantly reducing light transmission through the assembly.
Solution Approach 2:
The patent moves the connecting structures from the face of the display to the edges and sides of the circuit board. By placing connecting columns at the edges and using limiting plates on the rear side, the connection structures occupy a different spatial dimension that does not interfere with the light transmission path through the main display area.
3Ease of manufacture
If traditional splicing methods are used, then the connection is simple, but the transparency at connection points is poor
Solution Approach 1:
The patent segments the connection function into separate components: connecting columns for vertical connection, limiting protrusions for positioning, and limiting plates for lateral connection. This modular segmentation allows each component to be optimized for its specific function while maintaining overall transparency, and simplifies the assembly process through standardized interfaces.

AI summary
The present application discloses a transparent screen, including a first circuit board, an LED lamp bead and a plurality of first connecting columns. The first circuit board has a first surface and a second surface opposite to the first surface; the first circuit board includes a transparent portion provided with several first through holes and a mounting portion without through holes, and the LED lamp bead is mounted on the mounting portion of the first surface; and a first connecting column, mounted on the mounting portion of the second surface; where the first connecting column has a first limiting protrusion. The first connecting column is mounted on the mounting portion of the second surface which does not affect the transparency of the transparent screen.
