Problems solved by technology
For such a large-sized light guide plate, due to the above-mentioned light scattering, the intensity of light reaching the far end area of the light guide plate is significantly reduced, so that the brightness of this area is also significantly reduced
This reduces light output efficiency and also reduces brightness uniformity across the LGP

The invention discloses a light guide plate having a reinforcing surface optical structure and a technological method therefor. The light guide plate having the reinforcing surface optical structure comprises at least one reflection interface, wherein a light guide dot matrix or light guide strips are arranged on the reflection interface, and an inkjet layer is sprayed on the reflection interface or a spraying sand mark layer is formed on the reflection layer via spraying operation. The technological method for the light guide plate having the reinforcing surface optical structure comprises the following steps: an ink jet machine is arranged above the light guide plate, a spraying nozzle of the ink jet machine faces the light guide dot matrix or the light guide stripes of the light guide plate, and ink is sprayed on the light guide plate via the spray nozzle, and therefore the inkjet layer is formed. According to the light guide plate having the reinforcing surface optical structure and the technological method therefor, ink dots are sprayed on the light guide plate which has a reflection surface optical structure or the spraying sand mark layer is formed on the light guide plate via the spraying operation, and brightness uniformity of the light guide plate and light output efficiency can be improved in light guiding processes. Defects of the light guide plate and specifically a large-sized light guide plate that are uneven in brightness and poor in lighting efficiency can be overcome. The technological method is advantaged by simplicity, high efficiency, and capability of saving huge mold cost and greatly improving production yield of the light guide plate.
Description
technical field [0001] The invention relates to the technical field of optical transmission devices, in particular to a light guide plate with a reinforced surface optical structure and a process method thereof. Background technique [0002] The light guide plate in the prior art uses optical-grade acrylic / PC board, PS board and glass, and uses UV screen printing technology to print light-guiding dot matrix or stripes (micro-grooves) on the bottom surface of the optical-grade acrylic plate. ) or use laser engraving technology to engrave a light guide dot matrix or stripes (micro grooves). The optical grade acrylic sheet absorbs the light emitted from the lamp. Destroying reflection conditions are emitted from the front of the light guide plate. The scattering angle of the light scattering structure determined by the light guide lattice or stripes is inversely proportional to the propagation distance of light in the light guide plate (the actual travel distance of light from...
