Method for fabricating electric cold light sheet without joint shadow, and electric cold light sheet

Abstract

The invention comprises a transparent electrically-conductive membrane on which a fluorescent layer, a dielectric layer, a under line conducting layer, wire jumper insulation layer, a conducting layer and a back protection layer are sequentially printed. On the transparent electrically-conductive membrane, overlapping a fluorescent layer; on the a group of pattern block on fluorescent layer, overlapping a first dielectric layer having a pattern block in same size with the one on fluorescent layer; on the first dielectric layer, overlapping a first under line conducting layer having a pattern block in same size with the one on the first dielectric layer; on the second group of pattern block separated from the first group of pattern block, overlapping a second dielectric layer with a pattern block in same shape with the second group of pattern block and in larger size than the second group of pattern block; on the second dielectric layer, overlapping a second under line conducting layer, a wire jumper insulation layer, wires, and back protection layer all being in same size with the pattern block on the second dielectric layer.

Description

technical field [0001] The present invention relates to a method for manufacturing an electroluminescent sheet without seam shadows and the electroluminescent sheet, in order to reduce and eliminate the contrast between the shadow and the visual brightness between the light-emitting block and the boundary of the light-emitting block of the electro-luminescent product . Background technique [0002] Generally, when electroluminescent products run lights in sections, because the circuit must be arranged into multiple light-emitting blocks, the conductive layer between the blocks must be separated, so there will be insulating gaps between the blocks. Existence, if the block needs to be connected with the block, it must rely on the insulating jumper layer and the jumper. The main function of the non-conductive gap existing between the blocks is to separate the light-emitting blocks of the electroluminescent light, and to avoid short-circuiting of the conductive layers of differ...

Problems solved by technology

However, the non-conductive gap between the electroluminescent light-emitting blocks and blocks will form shadows, so that electroluminescent products will no longer need to be divided, and the integrity of a pattern will be lost.
