Lightweight LED Curtain Screen with Puncture-Contact Lamp Modules

The problem

Installing large LED curtain screens on buildings usually involves rigid frames, heavy cable harnesses, and individual soldering at every lamp node. When a single pixel fails, technicians must trace wires and desolder connections to replace it. Rigid structures also struggle to follow curved facades, limiting where the screen can be mounted. The weight of traditional frames increases shipping costs and demands stronger mounting hardware on the building itself.

The solution

This curtain screen addresses those issues with three structural changes:

1. Flexible linking. Horizontal connecting clamping strips (1) carry equidistant limit holes (11). Connecting ropes (12) thread through these holes to tie adjacent strips together. Because the ropes are flexible, the spacing between strips can be adjusted to match a curved building surface.
2. Clip-on lamp modules. Each lamp point monomer (2) is an independent unit. Its lower shell (22) has a second limit groove (36) that slides over a limit column (33) in a first limit groove (34) on the strip. Pressing the module down causes a fixing plate (35) on the shell to lock behind a stop body (32) on parallel second support plates (31), holding it in place without screws.
3. Solder-free wiring. Inside the lower shell, a first support plate (25) carries the LED (21). Below it, an insulating plate (43) holds puncture copper sheets (44) in placement grooves (47). Wires (42) run inside a support body (41) beneath the copper sheets. When the upper shell (23) is pressed down, its fixing columns (48) enter third limit grooves (46) and push the copper sheets through the wire insulation, contacting the conductors directly.

Who it is for

• Outdoor advertising operators who install large-format screens on commercial buildings and need faster setup with fewer wiring errors.
• Event production companies that build temporary stages and trade-show booths where screens must go up and come down repeatedly.
• Architectural lighting integrators working on curved facades or glass walls where rigid panels cannot follow the surface geometry.
• Display hardware brands looking to add a modular, lightweight curtain screen to their product catalog without developing the core structure from scratch.

How it works

The main parts

Assembly steps

1. Link the strips. Thread connecting ropes (12) through the limit holes (11) of adjacent connecting clamping strips (1) and fix them. Adjust the distance between strips to follow the target surface shape.
2. Position the module. Align the second limit groove (36) of a lower shell (22) with the limit column (33) on the strip, and seat the shell into the first limit groove (34).
3. Lock the module. Press the lamp point monomer downward. The fixing plate (35) on the shell passes the stop bodies (32) on the second support plates (31) and snaps behind them.
4. Close and connect. Place the upper shell (23) over the lower shell. As the fixing columns (48) enter the third limit grooves (46), they push the insulating plate (43) so the puncture copper sheets (44) pierce the insulation around the wires (42), contacting the conductors and powering the LED (21).
5. Seal the joint. Insert screws (54) through the through-holes (53) in the connecting blocks (51) into the thread grooves (56) of the connecting bodies (52). This compresses the sealing ring (57), whose mating plate (59) slides in the mating groove (58), closing the lamp point against water.

Applications

Building facade advertising

Media companies mount large screens on commercial towers. The rope-linked strips allow the display to follow curved glass or concrete surfaces without custom metal brackets, reducing installation time.

Stage and event backdrops

Concert and trade-show crews assemble temporary displays. Clip-on modules mean a damaged pixel can be swapped in seconds by unclipping one unit and snapping in another, avoiding rewiring during a live event.

Retail storefront windows

Shop owners hang transparent curtain screens behind glass. The lightweight structure puts less load on window frames, and the independent modules let the screen fit irregular window shapes.

Architectural accent lighting

Designers wrap columns or arches with light. Flexible connecting ropes permit the strips to bend around cylindrical structures while maintaining even module spacing.

Exhibition hall ceilings

Convention centers suspend overhead displays. Lower weight per square meter reduces the rigging requirements compared to solid LED panels.

Where it is less suitable

• Indoor fine-pitch video walls - boardrooms and control rooms that need very tight pixel pitch typically use solid panels rather than curtain structures.
• Permanent highway signage - road signs require specific regulatory approvals and rigid enclosures not addressed by this curtain format.
• Floor-mounted interactive displays - the clip-on housing is designed for suspended or wall-mounted use, not foot traffic loads.
