摘要： A light guide plate includes upper microstructures forming an upper surface. The upper microstructures are distributed in a successive convex-concave alternating arrangement in a direction perpendicular to propagation direction of light in the light guide plate. The light guide plate is divided according to the distance from the light source in the light propagation direction into a proximal side and a remote side. With H indicating height of shape features of the upper microstructures and P indicating spacing between the shape features of the upper microstructures, the shape features of the upper microstructures show a distribution that is variable in the light propagation direction in such a way that the variation satisfies the condition that aspect ratio H/P of the upper microstructures at the proximal side of the light guide plate is less than aspect ratio H/P of the upper microstructures at the remote side of the light guide plate.

摘要： A screening method of a phosphor-based optical film used in a backlight module and a backlight module are proposed. The screening method includes steps of: a) dividing an internal surface of the backlight module without a phosphor-based optical film into multiple measurement zones, and gaining a transmittance spectrum of each of the measurement zones; b) gaining a chromatic value of each of the measurement zones matching the phosphor-based optical film; c) checking the chromatic values gained in b) to be within a range of standard chroma; the process of screening being finished if all of the chromatic values are in the range; matching at least one measurement zone with a new phosphor-based optical film if the chromatic value of the at least one of the measurement zones is not within the range, and returning to b). The present backlight module has higher saturation and penetration and better color uniformity.

摘要： The present invention provides a light guide plate and a backlight module using the light guide plate. The light guide plate has an upper surface forming upper micro-structures and a lower surface forming lower micro-structures. The upper and lower micro-structures are set parallel to propagation direction of the light that emits from a backlight source traveling within the light guide plate. The upper and lower micro-structures each include a plurality of periodically and successively juxtaposed strip-like units. Each of the strip-like units forms a prism. The strip-like units of the upper and lower micro-structures are juxtaposed in the same direction. With the combination and arrangement of the upper micro-structures and lower micro-structures, collimation of light is improved after the light from an LED light source enters the light guide plate so as to improve convergence of the light inside a section.
