SCREEN AND LASER DISPLAY APPARATUS USING THE SAME

摘要

There is disclosed a screen including a first diffusion plate for transmitting a laser light for image display, a second diffusion plate spaced apart a preset distance from the first diffusion plate, and a plurality of optical transmission tubes arranged between the first diffusion plate and the second diffusion plate to transfer the laser light transmitted from the first diffusion plate to the second diffusion plate, wherein the optical transmission tube includes a body portion comprising a first surface facing the first diffusion plate and a second surface facing the second diffusion plate, vided in the body portion to a central region of the second surface provided in the body portion, and at least one optical fiber arranged in the through hole to transfer the laser light, only to reduce speckle noise of laser, and a laser display apparatus using the same.

主权项

1. A screen comprising:
a first diffusion plate configured to transmit a laser light for image display, a bid layer for optical diffusion provided on the first diffusion plate; a second diffusion plate spaced apart a predetermined distance from the first diffusion plate; and a plurality of optical transmission tubes arranged between the first diffusion plate and the second diffusion plate to transfer the laser light from the first diffusion plate to the second diffusion plate, wherein at least one of the optical transmission tubes includes:
a body portion including a first surface facing the first diffusion plate and a second surface facing the second diffusion plate;a through hole penetrated from a central region of the first surface provided in the body portion to a central region of the second surface provided in the body portion; andat least one optical fiber arranged in the through hole to transfer the laser light, wherein the first surface of the body portion provided in the at least one of the optical transmission tubes is spaced apart a first distance from the first diffusion plate such that an adhesion layer is provided between the first surface of the body portion and a first surface of the first diffusion plate, and wherein the bid layer is provided on a second surface of the first diffusion plate opposite the first surface of the first diffusion plate.
