摘要： A light guide plate (30) has a light incident surface (305) for receiving light, a light emitting surface (301) for emitting light, a bottom surface (303) opposite to the light emitting surface, and side surfaces (307, 309, 311). A subwavelength grating (302) is formed on the light incident surface for diffracting the light. The subwavelength grating is a zeroth-order grating which covers a wide wavelength band and diffracts the light into zeroth-order waves. So that the light guide plate has a high light utilization efficiency and yields high uniformity of outgoing light.

摘要： A backlight module (20) includes a light guide plate (22), a light source (21), and a reflection plate (23). The light guide plate includes a light incidence surface (221) for receiving light, a light emitting surface (223) for emitting light, and a bottom surface (222). The light source is disposed adjacent the light incidence surface. The reflection plate disposed under the bottom surface includes a base (232), and a reflection layer (233) formed on the base. The reflection layer defines a number of diffraction grating units (231) at an outer surface thereof. Grating constants of the diffraction grating units progressively decrease with increasing distance away from the light incidence surface. This enables the light emitting surface to output highly uniform light. Further, if the process of fabrication of the diffraction grating units fails, only the reflection plate need be discarded. Thus the backlight module has a low mass manufacturing cost.

摘要： A surface light source (4) includes a light guide plate (2) and a light source (5). The light guide plate has an incident surface (21) and an emitting surface (22). The light source is adjacent to the incident surface of the light guide plate for radiating light beams into the light guide plate through the incident surface. The emitting surface defines a large number of prisms (221), in which the distance (L) separating each two adjacent prisms changes according to an intensity of the light beams received from the light source. In particular, the pitch between two prisms decreases with increasing distance away from the light source. By the cooperation of the prisms and the light source, the surface light source has uniform illumination over the whole emitting surface.

摘要： A back light system (2) includes a light guide plate (50). The light guide plate includes an array of prisms (55) formed thereon, and a nano-particle layer (80) formed on the prisms for diffusing light beams propagating therethrough. The nano-particle layer contains a mass of transparent nano-particles with diameters preferably in the range from 30˜100 nm. A material of the particles may be TiO2 (titanium oxide), SiO2 (silicon dioxide), or Al2O3 (aluminum oxide). Each light beam passing through the nano-particle layer is scattered, and most of the scattering occurs over a limited range of angles. The scattered light beams exit the nano-particle layer mostly over the limited range of angles, with a medial direction of propagation in the range of angles being substantially parallel to a viewing direction. The back light system can yield high brightness and uniform luminescence, and is relatively simple in construction and inexpensive.

摘要： A light guide plate mold core (1) includes a main body (13) having a molding surface (12) and a plurality of concavities (13a) formed at the molding surface. The main body is made of a material whose thermal conductivity is limited in the range from 0.002 cal/cm.s.K. (calories/centimeter.second.Kelvin) to 0.009 cal/cm.s.K. The thermal conductivity of the material for the light guide plate mold core is less than that of stainless steel. Therefore the rate of spreading of heat in the light guide plate mold core is lower than that of a conventional light guide plate mold core, so that stresses within a formed light guide plate can be released more. Thus by using the light guide plate mold core, a light guide plate having a highly even bottom surface can be manufactured. A method for manufacturing the light guide plate mold core is also provided.
摘要翻译：导光板模芯（1）包括具有模制表面（12）的主体（13）和在模制表面形成的多个凹部（13a）。主体由导热系数限制在0.002cal / cm.s.K范围内的材料制成。（卡路里/厘米。开尔文）至0.009cal / cm.s.K。导光板模芯材料的导热系数小于不锈钢。因此，导光板模芯中的热扩散速度比常规的导光板模芯的散热速度低，从而可以更多地释放形成的导光板内的应力。因此，通过使用导光板模芯，可以制造具有高度均匀的底面的导光板。还提供了一种制造导光板模芯的方法。
