The raw material of the hot-pressed light guide plate is mainly divided into a flat plate and a plate with a structure on one side.
Flat panel applications are more common, and the newly developed models need to use a structural plate to meet the optical and picture requirements, but the structural shape and depth of the one-side structural plate are greatly affected, and the accuracy is currently difficult to achieve.
At the same time, it is difficult to adjust the optics and screen during the secondary printing of one side of the structural plate, and the structural surface is prone to damage, which will cause damage during printing and turnover transportation, and the production line yield rate at the customer end will be greatly affected. Based on ongoing costs and energy consumption reduce the requirements and therefore provide a light guide plate with double-sided thermocompression to improve brightness and uniformity。
The hot-pressed light guide plate adopts a flat plate, which meets the technical development requirements of low cost and low energy consumption; through the hot-pressing model of different shapes up and down, the double-sided light guide plate utilizes the structural surface of the second layer of the light-emitting surface to realize the enhancement of light refraction; The dot surface of the first layer makes the light fully reflected, and the dots are scattered, so that the light can be fully reflected and utilized, and the brightness and uniformity are comprehensively improved; wherein, the annular dots have the same diameter and dense hot pressure distribution, which further improves the light output. Hotspot on the screen and light incident side; the diameter of the annular dots is 10 μm-100 μm, and the distance between adjacent annular dots is 50 μm-200 μm.
It is suitable for the application requirements of mobile terminal backlight light guide plates; the diameter of the annular dots is 10 μm-100 μm; the distance between adjacent annular dots is 50 μm-200 μm, which is suitable for the application requirements of notebook display backlight light guide plates. The annular dots are designed with grooves. The light is fully reflected, and the dots are scattered, so that the light can be fully reflected and utilized, and the brightness and uniformity are further improved; arc convex strips or triangular convex strips are selected to meet the requirements of different customers, and the depth of the convex strips is 20 ～50μm, the peak spacing is 100～200μm, which is suitable for all kinds of backlight light guide plate application requirements, and this value further improves the brightness and uniformity.
