A kind of LED backlight light source of ultra-thin high photosynthetic efficiency includes mainly flourescent sheet, and the upper surface of the flourescent sheet is pasted with
The upper surface edge placement of LED chip, the flourescent sheet is machined with default route；The upper surface of the flourescent sheet and be located at LED
Envelope has guide-lighting insulation glue-line between chip；The surface of the guide-lighting insulation glue-line and LED core plate electrode is machined with a plurality of parallel wire
The electrode on road, LED chip is electrically connected by parallel line and default route；The side of the flourescent sheet, flourescent sheet bottom surface
And the electroplating surface of parallel line has nonconducting reflective layer.
A kind of LED backlight light source of ultra-thin high photosynthetic efficiency, specifically includes the following steps:
S1, selection and chip portfolio can export the flourescent sheet of specified colour temperature light, and such as exporting colour temperature is chip colour temperature itself
It is then slide；
S2, designated position mounts fixed LED chip on flourescent sheet；
S3, route is preset in flourescent sheet two sides or designated position；
S4, the guide-lighting insulating cement of slightly below LED chip thickness is enclosed in the upper surface of flourescent sheet；
S5, using PVD perhaps CVD chip electrode superficial layer growth conductive film reuse laser engraving or photoresist
The mode combined with etching removes extra conductive film, is left the parallel line of connection LED core plate electrode and default route；
S6, using PVD or CVD or be plating mode make on four sides and parallel line surface layer it is non-conductive
Reflective membrane.
As a further solution of the present invention: the thickness of guide-lighting insulation glue-line is lower than the height of LED chip.
The utility model has the beneficial effects that the utility model is whole face self-emissive light source, the authenticity and contrast of color
There is 25% or more promotion, it is more energy efficient under equivalent brightness output；When flourescent sheet uses flexible material, this light source is rollable.
