What's the difference between laser sampling of light guide plate and traditional printed light guide plate?

Long service life. Carving is a physical process, and the service life of light guide plate is mainly related to the quality of plexiglass substrate. Printed circuit boards often cannot be used for a long time. For example, most of the printed boards in ultra-thin light box, which have been used in Beijing subway station for less than two years, have experienced a serious decline in light transmittance. 2, the light guide is more uniform. When the width of the carved light guide plate is 1.2M, the light guide uniformity can still reach above 80%. 3, the light guiding effect is better and the performance is more stable. Under the same thickness, the light guiding effect of the carved light guide plate is obviously better than that of the printed board. Especially large format specifications, better light transmittance and more stable performance. When the width of the carved light guide plate with a thickness of 10MM reaches the target of 1.2M, the surface illumination can reach more than 2000LUX with a light source of 30 weight. 4. Each specification of printed light guide plate should be made separately, and the finished product cannot be cut at will, which has shortcomings in application. Our laser light guide plate can be made as a whole, cut and used at will, or made with special specifications. Adopt flexible technology. For products with large output but many specifications, such as luminous signs, the advantages are obvious. Compared with the traditional engraving light guide plate (precision mechanical scribing method), the laser spot light guide plate produced by our company has obvious and remarkable advantages. 1, the design of light guide spot is more reasonable. Combine different kinds of materials. Different ways of use, using different laser dot scheme. A uniform laser spot layout can be adopted. You can also make dot layouts of different sizes according to different specifications and usage methods. Achieve the perfect unity of generality and particularity. 2, the light guide is more uniform and the uniformity is higher. Different acrylic materials and personalized dot design make the light uniformity higher, reaching more than 90%. The whole is very uniform. 3, personalized dot design, better effect, effective use of the dense reflection of small points around, the edging function of large points in the middle, no dark lines and black holes at all. But also can produce special effects.
