摘要:
A backlight module includes a frame, a plurality of lamps in the frame, and an optical plate including a main body having a light input surface, and a light output surface opposite to the light input surface. The light input surface is adjacent to the lamps, and at least one bracket extension is integral with one end of the main body for fixing the optical plate to the frame. The at least one bracket extension includes a top surface for supporting a liquid crystal display panel, a side surface connecting with the top surface and being farthest from the main body, and a protecting protrusion located on the side surface for protecting a drive circuit connected to the liquid crystal display panel.

An exemplary optical plate includes a first transparent layer, a second transparent layer and a light diffusion layer. The light diffusion layer is between the first and second transparent layers. The light diffusion layer, the first transparent layer, and the second transparent layer are integrally formed. The light diffusion layer includes a transparent matrix resin, and diffusion particles dispersed in the transparent matrix resin. The first transparent layer defines first spherical depressions at an outer surface thereof that is farthest from the second transparent layer. The second transparent layer defines second spherical depressions at an outer surface thereof that is farthest from the first transparent layer. A backlight module using the optical plate is also provided.

An exemplary prism sheet includes a transparent main body. The transparent main body has a surface. A plurality of first elongated micro-protrusions and second elongated micro-protrusions protrude from the surface of the main body. Each of the first elongated micro-protrusions extends along a first direction. Widths and heights of each of the first elongated micro-protrusions vary along the first direction. Each of the second elongated micro-protrusions extends along a second direction that intersects with the first direction. Widths and heights of each of the second elongated micro-protrusions vary along the second direction. A method for making the prism sheet and a liquid crystal display device using the prism sheet are also provided.

An exemplary optical plate includes a first transparent layer (21), a second transparent layer (23) and a light diffusion layer (22). The first transparent layer includes an outer surface (210) and a plurality of semi-spherical depressions (211) protruding out from the outer surface. The second transparent layer includes an outer surface (230) and a plurality of conical frustum-shaped depressions (231) defined at the outer surface. The first transparent, the light diffusion layer, and the second transparent are integrally formed, with the first transparent layer in immediate contact with the light diffusion layer, and the second transparent layer in immediate contact with the light diffusion layer. The light diffusion layer includes a transparent matrix resin (221) and a plurality of diffusion particles (222) dispersed in the transparent matrix resin.
