Abstract: A package structure and a method of forming the same are provided. The package structure includes a first die, a second die, a first encapsulant, and a buffer layer. The first die and the second die are disposed side by side. The first encapsulant encapsulates the first die and the second die. The second die includes a die stack encapsulated by a second encapsulant encapsulating a die stack. The buffer layer is disposed between the first encapsulant and the second encapsulant and covers at least a sidewall of the second die and disposed between the first encapsulant and the second encapsulant. The buffer layer has a Young's modulus less than a Young's modulus of the first encapsulant and a Young's modulus of the second encapsulant.

Abstract: A backlight unit for an LCD is disclosed. The back light unit includes a light guide plate, a reflector, and a light source. The light guide plate has a light receiving lateral side, a first coupling lateral side, and a second coupling lateral side. The first and second coupling lateral sides include a first and a second coupling member, respectively. The reflector is disposed along the light receiving lateral side of the light guide plate, the reflector has a reflective cover, an opening, a first holder, and a second holder. The opening is positioned toward the light receiving lateral side. The first holder has a first linking member and extending toward the first coupling lateral side. The second holder has a second linking member and extending toward the second coupling lateral side. The light source is installed in the reflector, the light emitted from the light source is reflected by the reflective cover and then transmitted into the light guide plate.

Abstract: A backlight unit for a liquid crystal display is disclosed. The unit includes a light guide plate, a reflector, a light source and a frame. The light guide plate further includes a protrusion located on the side surface of the light guide plate, and the frame further includes a first groove, a second groove and a fixing portion. The first groove is connected with the fixing portion, and the second groove is also connected with the fixing portion. The light guide plate is combined with the frame by gliding and inserting the protrusions into the fixing portion through the first and second grooves.

Abstract: A uniform illumination device satisfies the demands of having a short optic path, a smaller beam size, and desired parallel beams. The uniform illumination device has a beam splitting device for converting light from a light source into a plurality of parallel beams, and a beam condenser for condensing the parallel beams to form a more uniform condensed light. The beam condenser has a first condensing lens made of a convex lens, and a second condensing lens made of a concave lens. When the parallel beams transmitted from the beam splitting device pass through the first condensing lens of the beam condenser, the parallel beams converge to the central axis. When the parallel beams pass through the second condensing lens, the parallel beams converge towards axes that are parallel with the central axis. The parallel beams transmitted from the beam splitting device are mixed to form the more uniform condensed light.
