Abstract
The utility model provides a photodiffusion sheet, comprising a transparent base material plate with one side coated with a resin layer and the other side printed with a printing ink layer; the printing ink forms circles on the surface of the base material plate; an outboard edge of the printing ink layer forms a inclined plane; and the inclined plane of the printing ink invaginates into the back of the side end of the base material plate. According to the photodiffusion sheet provided by the utility model, one side of the base material plate is trimmed to the resin layer to avoid shedding, whitening, unfilled corner and crack caused by protruded printing ink cut corner of a halogen-free printing ink layer, and also to prevent light leakage during usage.
Description
Technical field
The utility model relates to a kind of light diffusing sheet, relates in particular to a kind of light diffusing sheet with printing ink difficult drop-off of inclined-plane and product surface.
Background technology
In the display screen such as LCD or projector, in order to make the observer with wide view image, can produce and use light diffusing sheet.The structure of light diffusing sheet is that a transparent backing material plate surface coverage has synthetic resin layer, and synthetic resin layer is that the pearl with different size granularity forms, and light produces refraction by backing material plate and resin bed, forms diffusion effect.
When reality was used, light diffusing sheet carried out halogen-free ink printing at the periphery on its surface as required, prevents from taking place in use the situation of light leak, bright line.Then by in the one side of backing material plate along the ink printing frame, cut the back as required and use.As shown in Figure 1, cutting knife 4 upwards cuts from resin bed 1, causes ink lay 3 to cut pin 31 at the end formation printing ink of backing material plate 1.Described printing ink is cut the side end face 33 that pin 31 protrudes from described backing material plate 1, is scraped easily in use, forms the unfilled corner of light diffusing sheet or bursts apart, and can cause light leakage phenomena during use, influences the effect of light diffusing sheet.
The utility model content
The purpose of this utility model is to solve above-mentioned technical matters, and a kind of light diffusing sheet and cutting method thereof are provided.
The purpose of this utility model is achieved through the following technical solutions:
Light diffusing sheet, comprise the transparent base plate, the one side of described backing material plate is coated with resin bed, the described another side that is printed in backing material plate is printed with ink lay, described ink lay forms the border on the surface of backing material plate, described ink lay outer ledge forms an inclined-plane, sinks into the rear of the side end face of backing material plate in the inclined-plane of described printing ink.
The cutting method of above-described light diffusing sheet comprises the steps: that the backing material plate of described light diffusing sheet and cutting knife are oppositely arranged, described cutting knife from backing material plate top toward layer side resin to cutting.
The beneficial effects of the utility model are mainly reflected in: avoided the evagination of halogen-free ink lay to go out printing ink and cut pin and cause that coming off of printing ink edge turned white when using, unfilled corner and the phenomenon of bursting apart simultaneously, light leakage phenomena occurs when also having prevented use.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: the structural representation that adopts the light diffusing sheet of prior art cutting method.
Fig. 2: the structural representation that adopts the light diffusing sheet of the utility model cutting method.
Embodiment
The utility model has disclosed a kind of light diffusing sheet, in conjunction with shown in Figure 2, consistent with prior art, 1. light diffusing sheet, comprise transparent base plate 2, the one side of described backing material plate 2 is coated with resin bed 1, and the described another side that is printed in backing material plate 2 is printed with ink lay 3, and described ink lay 3 forms the border on the surface of backing material plate 2.
Different is that described ink lay 3 outer ledges form an inclined-plane 32, sink into the rear of the side end face 33 of backing material plate 2 in the inclined-plane 32 of described printing ink.Concrete, caving in refers to that the inclined-plane tilts to 33 rears, side end face of backing material plate 2.Because the structure on printing ink inclined-plane 31, making can finally not influence the actual usability of light diffusing sheet owing to grazing causes that the unfilled corner of printing ink forms coming off of printing ink and causes turning white when using.
The cutting method of the light diffusing sheet with acute angle that the utility model is related, consistent with existing cutting method, do not repeat them here.Different is, backing material plate 2 and the cutting knife 4 of described light diffusing sheet are oppositely arranged, and described cutting knife 4 cuts from backing material plate 2 tops toward resin bed 1 direction.
The utility model still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
