Abstract: A head-mounted display including a device body, an assembly and a projection device is provided. The assembly includes a reflective surface, and is pivoted on the device body. The projection device includes a liquid crystal lens element, and is disposed inside the device body. The projection device is used to project an image beam on the assembly, and the assembly reflects the image beam to a projection target. The projection device uses the liquid crystal lens element to calibrate an aberration generated from the reflective surface of the assembly.

Abstract: A head-mounted device including a main body, a projection device and a beam combiner is provided. The main body has an upper shade portion and a lower shade portion, wherein the upper shade portion and the lower shade portion have an opening defined therebetween. The projection device is disposed within the lower shade portion and adapted to generate a projection beam, and the projection beam is adapted to be transmitted from the lower shade portion to the opening. The beam combiner is connected to the upper shade portion and located in the opening, wherein the beam combiner is located at a transmission path of the projection beam to be adapted to reflect the projection beam into the main body.

Abstract: An image display apparatus adapted to dispose in front of at least one eye of a user and including a frame, a projecting optical system, at least one waveguide and at least one lens is provided. The projecting optical system is configured to provide an image beam and disposed on the frame. The waveguide and the lens are disposed on the transmission path of the image beam. The waveguide has a side surface and the side surface has a first curvature. The waveguide is disposed on a surface of the lens. The surface has a second curvature and the first curvature is the same as the second curvature to bond the side surface and the surface with each other. The image beam is transmitted to the eye through the lens to display a virtual image after being transmitted to the lens through the waveguide.

Abstract: A prism system and method for eliminating color aberration in an illumination system of a micro projector is disclosed. A light beam enters into a first prism through a light incident surface thereof and is further emitted through a light-emitting surface of the first prism. The light beam then enters into a second prism through a first interface thereof, passes through a second interface of the second prism and reaches a digital micromirror device (DMD). The light beam is reflected by the DMD so as to pass through the second interface and reach the first interface. The light beam is totally reflected by the first interface so as to be emitted through a third interface of the second prism. Therefore, the invention eliminates lateral color aberration that occurs in an active area of the DMD, reduces costs of illumination equipment and achieves a preferred projection effect.

Abstract: A wide-angle illumination light-emitting diode (LED) light bulb includes a light base formed of a heat dissipation module having an end to which a circuit board is mounted. The circuit board carries at least one LED that is mounted to the circuit board in a chip-on-board fashion. A global cover is arranged above and covers the LED of the light base heat dissipation module. Intense white light generated by the LED is allowed to emit from the global cover with a wide angle of illumination similar to a conventional light bulb thereby realizing wide and uniform illumination.

Abstract: The illuminating device structure contains a heat-dissipating base, a circuit board on a top side of the heat-dissipating base, and at least a naked, high-powered LED die on the circuit board. A hollow cover is configured on the heat-dissipating base to cover the LED die. A phosphor layer is coated on an interior wall of the cover and a space is thereby reserved between the phosphor layer and the LED die. As such, the phosphor layer is protected against the heat and high temperature from the LED die by the space and therefore would enjoy an extended operation life.

Abstract: A heat/electricity discrete metal core-chip on board Module includes a heat dissipation substrate, which has a surface that is recessed to form a carriage zone and a relatively elevated engagement section; a dielectric layer, which is formed of a compound that is formed on the heat dissipation substrate through conversion coating and covers the carriage zone of the heat dissipation substrate, the dielectric layer defining a window like heat conduction zone at a location corresponding to the engagement section of the heat dissipation substrate, so that the heat conduction zone corresponds exactly to the engagement section of the heat dissipation substrate; and an electrical connection layer, which is formed on the dielectric layer. A chip is set on the heat conduction zone and is connected to the electrical connection layer through wire bonding, whereby the paths for heat transfer and electricity transmission are separated.

Abstract: A conductive slice structure includes a substrate, a carbon nanotube (CNT) layer, and a first function layer. The conductive slice structure may further include a second function layer and a third function layer. The first function layer, the second function layer, and the third function layer each of which can be a refraction layer, an anti-smudge layer, an anti-fingerprint layer, an anti-glare layer, an anti-Newton rings layer, an anti-static layer, or an anti-scratch layer.

Abstract: A multi-function, multi-layer optical film is disclosed herein. The most basic structure of the optical film contains a first hard coat layer on a front surface of a transparent substrate. The first hard coat layer can integrate in itself the anti-glare, anti-smudge, anti-UV, and anti-static functions by blending appropriate amount of specific chemicals into the acrylate resin of the first hard coat layer. The first hard coat layer is made of acrylate resin containing an appropriate amount of polyoxetane polymers with pendant side chain having at least a fluorocarbon (C—F) bond. The constituent fluorine modifies the surface energy of the first hard coat layer so that additional function-enhancing layers can be developed from the front surface of the basic structure reliably.

Abstract: Provided is an LGA socket of rectangle comprising four side walls wherein at least one of the walls is not fixed, a plastic housing provided on an enclosed space of the socket and comprising a plurality of apertures arranged in rows and columns, and a plurality of conductors each substantially concealed in the aperture and having a head being in contact with one of bottom contacts of a CPU in a vertical manner. Each unfixed wall comprises one or more latches on its inner surface such that pressing the CPU onto the space will cause the CPU to pass the latches until top of the CPU is fastened by the latches. The invention is advantageous for increasing contact reliability by causing no lateral displacement to heads of the conductors.
