Abstract: The present invention relates to a method of controlling unwinder splicing in a gravure processing facility. In an automatic splicing control method, a fabric of a working roll is cut and adheres to a fabric of a standby roll which rotates along with the rotation of the working roll in an unwinder supplying the fabric, without interrupting the operation of the facility. The method of the present invention includes the steps of releasing a back roll pressed against a gravure roll in the process of the automatic splicing due to the consumption of the fabric of the working roller in the unwinder; interrupting surface processing of the fabric in the step of releasing the back roll; operating the automatic splicing in the step of interrupting the surface processing of the fabric, and starting to operate a counter which is in synchronized with the operation of the back roll of the gravure processing facility; and controlling to press the back roll against the fabric and the gravure roll after the preset distance or time of the counter passes from the step of starting to operate the counter. Therefore, since the operation of the back roll is controlled during the automatic splicing of the unwinder, it is possible to prevent contamination of a product and the facility, and minimize volatilization of a coating solution.

Abstract: The present invention relates to a light diffusion sheet for a thin backlight unit having a shielding function capable of preventing hot spots on an LCD backlight unit using LED lamps by regularly diffusing or shielding light from the LED lamps by coating fine particles with a thin film and a manufacturing method thereof. The light diffusion sheet for a thin backlight unit given in the present invention includes: a transparent polyester base film; and a light diffusion layer formed on at least one surface of the film. The light diffusion layer is formed by applying binder resin and a mixture of particles having different diameters and making the particles form a single layer in the binder resin. For the light diffusion sheet for a thin backlight unit described above, binder resin and a mixture of particles having different diameters are applied on the surface of the base film to form a single layer of particles having different diameters. As a result, since the thickness of coating is reduced by 5-7μm compared to the existing light diffusion sheet, the present invention is able to enhance brightness and shielding performance, thereby resolving the problem of the existing light diffusion sheet that the coating layer is too thick to be used for a thin backlight unit.
