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.

Abstract: A lens used for a light-emitting diode (LED) includes a body having an axis and a retaining part, wherein the body of the lens is symmetrical about the axis. The lens is mounted onto an LED and further includes a first lens part and a second lens part. When entering into the first lens part, light rays will be totally reflected through the first lens part and the light rays emitted from the first lens part will approximately parallel to the axis. When the light rays emitted from the first lens part enter into the second lens part, they will be totally reflected, and the light rays emitted from the second lens part will be approximately perpendicular to the axis. Thus, the lens has a structure that may control the emitting direction of light emitted from an LED.

Abstract: 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.
