    摘要: A polarizer (2) for a liquid crystal display device includes a polarizer base (21), a first protective layer (20) and a second protective layer (22) on two sides of the polarizer base for protecting the polarizer base, and an anti-reflection layer (25) on the first protective layer. The anti-reflection layer includes a first layer (26), a second layer (27), a third layer (28) and a fourth layer (29) stacked in order. The anti-reflection layer of the polarizer can reduce the reflection of the light irradiated on the polarizer, and the loss of light can be reduced and higher light transmission rate can be achieved.

    摘要: A light-emitting diode (LED) (110) includes a chip body (113), an encapsulation can (115) surrounding the chip body, and a base (111) supporting the encapsulation can and the chip body thereon. A diffraction grating (117) is provided at a surface of the encapsulation can, and the encapsulation can is made of a piezoelectric material for widening radiation angles of light beams emitted from the chip body. With the diffraction grating and the piezoelectric encapsulation can, light beams from the chip body are diffracted and attain wider radiation angles. A backlight system (100) includes a light guide plate (120), and a number of the above-described LEDs disposed adjacent to the light guide plate. Light beams having wide radiation angles are emitted from the LEDs and enter the light guide plate. This enables a light-emitting surface (122) of the light guide plate to have highly uniform brightness.

    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 (20) has a light incidence surface (221) for receiving light, a light emitting surface (223) for emitting light, and a bottom surface (222). The light emitting surface has a plurality of diffraction grating units. Each diffraction grating unit has a strong diffractive portion and a weak diffractive portion. In each diffraction grating unit, grating directions of the strong and weak diffractive portions are orthogonal to each other. Area ratios of the strong diffractive portions in the diffraction grating units progressively increase with increasing distance away from the light incidence surface. The grating directions of the strong diffractive portions may vary according to the locations of the diffraction grating units relative to a light source. These features improve the overall efficiency of utilization of light, and enable the light emitting surface to output highly uniform light.

    摘要: A lithium ion battery includes a cathode (10) having a plurality of nanoparticles of lithium doped transition metal alloy oxides represented by the formula LixCoyNizO2, an anode (20) having at least one carbon nanotube array (22), an electrolyte, and a membrane (30) separating the anode from the cathode. The carbon nanotube array includes a plurality of multi-walled carbon nanotubes (23). Preferably, an average diameter of an outermost wall of the multi-walled carbon nanotubes is in the range from 10 to 100 nanometers, and a pitch between adjacent multi-walled carbon nanotubes is in the range from 20 to 500 nanometers. In the carbon nanotube array, the lithium ions are able to intercalate not only inside the multi-walled carbon nanotubes, but also in the interstices between adjacent multi-walled carbon nanotubes. Thus a density of intercalation of the carbon nanotube array is significantly higher than that of graphite.

    摘要: A surface light source (3, 4, 5) includes a light guide plate (32, 42, 52), which defines an incident surface (321, 421, 521), an emitting surface and a bottom surface (323, 423, 523) opposite to the emitting surface; and a light source (31, 41, 51) adjacent to the incident surface of the light guide plate for radiating light beams into the light guide plate through the incident surface. A multiplicity of generally rectangular dots (328, 428, 528) and generally circular dots (329, 429, 529) is formed on the bottom surface of the light guide plate. The rectangular and circular dots reflect and scatter the light beams in directions toward the emitting surface. The rectangular dots are distributed on the bottom surface corresponding to lower luminance areas of the light guide plate, so that the luminance over the whole emitting surface of the light guide plate is uniform.
