1. The development process of Acrylic light guide plate
doping
A transparent particle material with scattering function that is
directly injected into the light guide plate during the injection
molding of the light guide plate. By adjusting the concentration of
the transparent particles reasonably, the light output can be
effectively controlled, and finally the high uniformity of the
light output can be achieved. Since the doping process is not easy
to precisely control, the injection molding method is suitable for
the production of small and medium-sized light guide plates, and
the problem of uneven light output will occur for large-sized light
guide plates.
laser engraving
The laser engraving production method is to use a computer to
strictly control the energy emitted by the laser head and the
position of the laser head according to the program requirements,
and to engrave a microstructure array with a certain size on the
back of the light guide plate by gasification. This method can be
very accurate. The depth of the scattering structure is controlled,
but the efficiency is very low and it is not convenient for mass
production.
sandblasting
Use sandblasting to make a mold with a rough distribution surface.
During injection molding, transfer the rough distribution on the
mold to the light guide plate. The more rough surfaces, the
stronger the scattering ability. By adjusting the rough
distribution of the surface reasonably The light reaching the
light-emitting surface is evenly distributed.
Single point diamond machining
Single-point diamond machining is also called nano-machining
technology, and its machining accuracy can reach nano-level surface
roughness. It fixes the workpiece on a precision lathe and uses
natural single crystal diamond tools for fixed-point turning.
First, fix the light guide plate mold core on the rotating shaft to
rotate, and then use the fast piezoelectric feed of the diamond
knife to complete the production. The concave-convex lens of the
light guide plate is processed by the fast tool feeding system and
the ultra-precision single-point diamond equipment.

3. Clear Acrylic Light Guide Plate Laser Dot Advantages
Compared with the traditional engraving light guide plate
(precision mechanical scribing method), it has obvious and
significant advantages.
1. The light guide point design is more reasonable. Combine
different acrylic materials. Different ways of use use different
laser network solutions. Both uniform and uniform laser dot layout
can be used. You can also make network layouts of different sizes
according to different specifications and ways of use. To achieve
the perfect unity of commonality and exclusivity.
2. The light guide is more uniform and the evenness is higher.
Different acrylic materials and personalized dot design make the
light guide even higher, and the light evenness can reach 90% or
more. Overall very uniform.
3. Personalized network design, better effect. Effective use of
dense reflections from surrounding small points.
4. What is the relationship between the acrylic light guide plate
and the acrylic plate?
The light guide plate is made of optical-grade acrylic sheet, and
then uses high-tech materials with extremely high reflectivity and
no light absorption to print light-guiding points on the bottom
surface of the optical-grade acrylic sheet with UV screen printing
technology.
The main material of the acrylic light guide plate is optical
acrylic plate. The quality of the acrylic light guide plates
currently produced is also different due to the different processes
of different manufacturers. In particular, although the price of
the recycled board is cheap, it is easy to yellow and the light
transmittance is also poor. The production of acrylic light guide
plate should not be easy to yellow and transmit light. Transparent
board with a rate of 92%-93%.
At present, the light guide plates on the market are made of two
materials: acrylic sheet and PC sheet. However, the most common
light guide plate is made of acrylic board material. There are
fewer light guide plates made of PC board material, and they have
to be specially customized, and not every manufacturer of light
guide plates does it.
