A computer includes a motherboard, a heat-generating device mounted on the motherboard, a heat-conducting device attached to the heat-generating device for absorbing heat energy generated from the heat-generating device, and a thermoelectric converter coupled to the heat-dissipating device for converting the heat energy into electric energy for recycling use. The heat-conducting device includes a heatpipe. The heatpipe contains a working fluid, which has nano-sized particles therein. The nano-sized particles may be composed of carbon and/or a metallic material. The computer may include a heat-conducting plate interposed between the heatpipe and the heat-generating device. The thermoelectric converter may include a circuit with two strips connected in series, the strips each being formed of a different kind of thermoelectric metal. Corresponding ends of the two strips would be coupled to the heat-conducting device so as to receive heat energy therefrom.

The present invention provides a surface light source (6) using a light guide plate (2) to illuminate a liquid crystal display. The light guide plate comprises a light incident surface (21), a light-emitting surface (22) perpendicular to the light incident surface, a bottom surface (23) opposite to the light-emitting surface, and a plurality of side surfaces. An anti-reflective coating is formed on the light incident surface and the light-emitting surface. A reflective coating is formed on the bottom surface and at least one of the side surfaces. The light guide plate provides a high luminace output for the liquid crystal display.

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.

A method of for fabricating a stamper includes the following steps: (a) providing a substrate (30); (b) coating a photo-resist layer (50) on the substrate; (c) exposing and developing the photo-resist layer to form a photo-resist pattern (52); (d) etching the substrate; and (e) removing the photo-resist pattern to thereby provide the stamper. The method of the present invention does not require an electroforming step or create an electroformed layer. The formed stamper only includes a derivative of the substrate, which is made of nickel or steel. The substrate can have a large thickness, in order that the substrate has a high rigidity. Thus, the stamper resists distortion and has a long service life.

A method for fabricating a mold core (30) includes the following steps: mixing a silicone elastomer with a curing agent (S901); defoaming bubbles of the mixture (S902); forming a layer (10) of the mixture on a substrate (20) having a predetermined surface structure formed thereon (S903); curing the layer of the mixture (S904); and separating the cured layer from the substrate to provide the mold core (S905). Unlike in the prior art, there is no need for steps of forming a photo-resist pattern, forming a Cu layer, and/or etching the Cu layer off. Thus, the method of the present invention has reduced complexity and costs compared with the method of the prior art. In addition, the obtained structure of the mold core corresponds more closely to the predetermined structure of the substrate. That is, the precision of the mold core is significantly increased.

An injection mold (120) includes a stationary mold (121), a movable mold (122), and a core. The movable mold defines a cavity (126). The core is disposed in the cavity of the movable mold opposite from the stationary mold. The stationary mold includes a curved runner (125), and a flared gate (123) having an opening at least half the size of an opening of the cavity. With the combined runner and gate structure, movement of molten resin is slowed, and different portions of the cavity are filled up with molten resin virtually simultaneously. Accordingly, different portions of the molten resin are cooled at the same time, so that the light guide plate has an even density and low stress concentration. The light guide plate can then provide highly uniform brightness.
