“…Usually, these small devices require the production of micro and nano-scale patterns with different shapes and geometry. For instance, microfluidic devices with micro to nanopattern structures had been used to maximize the sensitivity in detecting analytes [7][8][9]. On the other hands, micro lenses are utilized to enhance camera image quality [10] and light guide plate (LGP) also contain microstructure pattern on the surface of the material to distribute light evenly [11,12].…”

Light guide plates (LGPs) are an integral component that help distribute illumination from the light source in a variety of applications. Therefore, the design and quality of the microstructure pattern in LGPs play a significant role in achieving high luminous efficiency and light uniformity. This study investigates the relationship between laser power and laser scanning speed to the formation of micro-dots by using CO2 direct laser structuring on PMMA. Furthermore, the effect of different micro-dots pitch to the luminance was also evaluated using the luminance meter. Our finding shows that increase of laser power and decrease of laser scanning speed resulted in larger micro-dots diameter and deeper micro-dots. The results also showed that the smaller the pitch, the higher the luminance reading. Overall, the low-cost CO2 direct laser structuring demonstrated in the study able to produce consistent micro-dots pattern diameter and height which is suitable for fabrication of LGPs in the mass production.

The full‐screen mobile phone can be fabricated by integrating the camera beneath the screen, which needs the nanocomposite light guide plate (nano‐LGP) with exceptional transparency and light‐guiding properties simultaneously. Choosing an appropriate nanoparticle with a high refractive index and exceptional compatibility within the polymer matrix is crucial for producing the nano‐LGP. In this study, the high refractive index carbonized polymer dots (HRI‐CPDs) are synthesized through the solvothermal treatment, achieving a refractive index value of 1.7220 at 450 nm. Subsequently, the modified HRI‐CPDs (mHRI‐CPDs)/polymethyl methacrylate (PMMA) nanocomposites are fabricated by copolymerizing the mHRI‐CPDs with methyl methacrylate . Due to the high visible light transmittance and Rayleigh scattering characteristics when light passes through the nanocomposites, this kind of nanocomposites is suitable for serving as nano‐LGPs. The potential of carbonized polymer dots as light‐scattering unit is originally explored to improve surface illuminance and uniformity of nano‐LGPs. The best‐performing 4.3‐inch LGP with 1.0 wt.% doping content shows 15.8 times higher surface illuminance and 2.1 times higher uniformity than pure PMMA. This new type of LGP based on mHRI‐CPDs/PMMA nanocomposite holds tremendous promise in conjunction with advanced liquid crystal display technology.
