VynEL™ Panels
How to safely trim VynEL™ panels to size and make electrical connections. Covers the panel's internal construction, where and how to cut, stripping the leads, connecting to an inverter, and critical zones to avoid.
Understanding VynEL™ Panel Construction
Before cutting or connecting, you need to understand what's inside a VynEL™ panel. The panel has several laminated layers: a transparent front electrode, the phosphor-barium titanate dielectric stack that produces the light, a rear electrode (the bus bar layer), and the outer protective laminate.
The bus bar runs along one or more edges of the panel. It is the current-collection conductor that distributes power across the full panel area. The flex cable leads exit the panel from the bus bar zone. These are the two areas you must never cut into or damage.
Do not cut here
Never cut through the bus bar or the flex cable lead area. Cutting the bus bar creates an open circuit in that section of the panel and causes a permanent dark zone that cannot be repaired. The bus bar runs along the edge of the panel — if your cut line is near any panel edge, confirm you are clear of it before cutting.
Can You Cut VynEL™?
Yes, with important constraints. VynEL™ panels can be trimmed to size, but the following rules apply:
- Cuts must be parallel to and clear of the bus bar. A perpendicular cut across a bus bar destroys that edge's power distribution.
- Cut edges must be sealed after trimming. The raw cut edge exposes the internal layer stack to moisture and mechanical contact. Apply waterproof edge sealant or clear silicone along all cut edges.
- For production or complex shapes, do not cut — order to spec. Custom shapes are manufactured at the panel level with correct bus bar placement, sealed edges, and lead routing for your exact geometry. This is almost always the right path for anything beyond a simple trim.
- Do not cut VynEL™ Cling unless you are an experienced installer. The adhesive layer on Cling panels behaves differently when cut and the edge requires different sealing treatment.
Trimming a Panel
01
Mark your cut line and confirm bus bar clearance
Use a straight edge and marker to draw your cut line on the back of the panel. Hold the panel up to a light to see the internal structure. The bus bar will typically be visible as a denser opaque line along the edge where the leads exit. Your cut line must stay at least 5mm away from the bus bar in all directions.
02
Cut with a sharp utility knife or scissors
A sharp utility knife and straight edge gives the cleanest cut. Scissors work on smaller panels. Make the cut in a single clean stroke if possible — multiple passes can delaminate the edge. Avoid tearing or bending the panel at the cut line.
03
Seal the cut edge immediately
Apply clear silicone sealant or panel edge sealant along the full cut edge before the panel is used in any application. Allow full cure time before installing. Unsealed edges are a moisture ingress point that will degrade the panel from the edge inward over time.
Making the Electrical Connection
VynEL™ panels ship with a flex cable lead that terminates in a bare end or a JST connector, depending on configuration. The flex cable has two conductors: a main power lead and a return. Do not reverse polarity — AC-driven EL panels operate on both phases of the AC cycle, but the inverter output polarity still matters for connected indicator circuits and some controller configurations.
01
Prepare the leads
If the flex cable has a JST connector, plug it directly into the inverter — no stripping needed. If the lead is bare-end, strip approximately 5mm of insulation from each conductor using a wire stripper sized for the lead gauge. Do not nick the conductor strands.
02
Slide heat shrink tubing onto the leads before soldering
Before you make any solder joint, slide heat shrink tubing over the leads so it can be moved into position after soldering. Heat shrink cannot be added after the joint is made.
03
Connect to the inverter or splitter
For a single panel, connect the flex leads to the inverter output using the JST connector or by soldering to a pigtail connector. For multiple panels on one inverter, use a splitter rated for the combined panel area. Total panel area drives power draw — size your inverter accordingly. See the Power Guide for inverter sizing calculations.
04
Insulate all connections
Slide the pre-positioned heat shrink tubing over each solder joint and apply heat to shrink. All exposed conductor must be covered. EL panels operate at AC voltages (80 to 200V depending on inverter) — exposed connections inside a garment are a safety hazard.
05
Power on and test before final assembly
Always test the panel before completing any final stitching, bonding, or installation. Confirm the full panel illuminates evenly with no dark zones. Flickering at startup is normal for cold panels — allow the system to run for 30 seconds before evaluating brightness. Persistent dark zones indicate a connection issue or panel damage and must be resolved before the build is completed.
Connecting Multiple Panels in Parallel
Multiple VynEL™ panels connect in parallel to a single inverter, not in series. All panels receive the same AC voltage. Power draw scales with total area. Use a multi-output splitter to connect several panels cleanly without additional soldering. See the Power Guide for total draw calculations before selecting an inverter for multi-panel builds.
Custom shapes
For any complex shape, we strongly recommend ordering to spec rather than cutting. Custom panels are manufactured with bus bar placement, lead routing, and edge sealing optimized for your exact geometry. Contact us with your drawing or dimensions: info@ellumiglow.com
