led film

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.
