The planar light emitter consists of five layers: panel B layer (mainly for identification); cushion layer (mainly for connecting panel B with the circuit layer to achieve sealing and connection effects, with high viscosity and anti-aging properties); control circuit layer (the control circuit layer uses a polyester film with good performance as a carrier, and uses a special process to screen print silver paste to make it conductive, and its thickness is generally within 0.2mm), which is easy to install; interlayer (this layer has a similar function to the cushion layer); back glue layer (the back glue material is 3M waterproof glue, which can be directly attached to the reserved position of the rod body).
