The present invention relates to a diffusion plate used in a direct-type backlight module and a method for making the same. At least one of the surfaces of the diffusion plate has a microstructure constituted by repeated undulation that can refract and diffuse the incident light beams that enter the diffusion plate. Therefore, the paths of the light beams after entering the diffusion plate are changed, which raises the luminance of the backlight module.

Diffusion plate used in direct-type backlight module

A light-mixing module includes a luminous panel having a plurality of red, green, and blue illuminants arranged alternately, at least one corner being formed in an area defined by the arrangement of the illuminants, a predetermined illuminant being located at the corner; at least one mask located above the luminous panel and over the corner for attenuating the light emitted therethrough from the predetermined illuminant thereunder and having a transmittance preferably lower than 90%; and a light-mixing panel located above the luminous panel and the mask. The light emitted from the illuminants passes through the light-mixing panel for mixture to generate required colored light and then to emit outward. Accordingly, the mask prevents the predetermined illuminant from displaying a weighted color, thus attaining the potency of even light mixture.
