transparent led film display

       led transparent film screen There are two types of film screens, one is a hard light bar, or a hollow

PCB, and then a groove in the shape of the PCB is carved into a transparent plastic sheet (such as PC,

acrylic, etc.), and then the PCB is placed in the groove , then cover it with a film, and stick the other

surface to the glass with adhesive, like a layer of LED light film. It is actually relatively thick, and the

relatively thin ones are 2.5mm thick.

Crystal film screens generally use transparent flexible circuit boards. After the conductive circuits are made,

the lamp beads are mounted on the transparent circuit boards and then encapsulated with transparent materials

to make flat surfaces. They are divided into two types. This type is the largest. The problem is that the expansion

coefficients of the metal conductive layer on the surface and the transparent plastic substrate below are different

after being heated, resulting in delamination and deformation. Secondly, the conductivity of the metal conductive

layer is not high and the brightness is very low. Usually the brightness can only be 1500CD/M; There are also

various circuit designs, as long as the transparent effect can be achieved.
