Print light guide Plate£º
In the past, light guide Plate printing had been done by means of the frequently used method
i.e. evenly distributing light source using high light emitting substances (such as SiO2 and
TiO2) printing materials.They are appropriately distributed on the base of the light guide Plate.
The light absorbant and diffusive property of the printing material are then utilized to destroy
the internal diffusion caused by total reflection .so that light is emitted from the front side and
is evenly distributed in the light emitting area.
Injection
Etch method(imprint pattern) :
directly transfer printing point design into model; replace the traditional printing method with
actual brightness expressions; etched light guide plate is less ideal than printed light guide
sheet
Cutting processing :
Produce a long slender structure by cutting the front of the light guide plate; the mirror design
is similar to the prism structure to produce brighter results. However, in terms of uniform
expressions, it is less ideal than the printed light guide plate structure.

Printing point is printed using high-reflective or high-refractive material mixed ink at the
reflective side of the light guide Plate, light path is altered to form diffuse reflection results
