Abstract: A curve-shaped display module, a manufacture method thereof, and a manufacture apparatus for manufacturing the same are provided. The manufacture apparatus includes a curve-forming mold, a curable material-dispensing device, and a curing device. The manufacture method includes the following steps: pressing the display panel to make the display panel have a curved shape and a first curved surface by using the curve-forming mold; distributing a curable material on the first curved surface by using the dispensing device; and curing the curable material to form a cured casing by using the curing device. The display module has the display panel having the first curved surface and the cured casing formed from the curing of the curable material. The cured casing covers and is closely attached to the first curved surface with an adhesion force therebetween to sustain the curved shape of the display panel.

Abstract: A liquid crystal panel module, a backlight module and a liquid crystal display (LCD) are provided. The liquid crystal panel module includes a liquid crystal panel and a diffraction grating layer. The liquid crystal panel has a plurality of pixels. The diffraction grating layer is disposed on the liquid crystal panel, and a maximum period of a grating of the diffraction grating layer is smaller than 1/10 of a size of the pixels. The backlight module includes a light guide plate, a light emitting element and a diffraction grating film. A light provided by the light emitting element emits from a light emitting surface of the light guide plate and is bended towards the light emitting element after passing through the diffraction grating film. The liquid crystal panel module and the backlight module can be applied to the LCD together or individually.

Abstract: A shower head with water-powered vibrating function wherein a diverting member is disposed in the water diversion chamber which is operable by a diverting member actuating means between a normal shower position and a massage shower position. At the normal shower position the diverting member diverts water flow received from the water diversion chamber inlet to leave the water diversion chamber through the first water diversion chamber outlet for exiting the shower head through a first water outlet; and at the massage shower position, the diverting member diverts water flow received from the water diversion chamber inlet to leave the water diversion chamber through the second water diversion chamber outlet for entering the turbine chamber for rotating the turbine and thereafter leaving the turbine chamber to exit the shower head through a second water outlet.

Abstract: Techniques and devices are disclosed to enhance or increase the viewing angle of liquid crystal display (LCD) device through the use of one or more types of optical films. Such optical films can include arrays of prism structures and/or diffractive elements that redirect light that has passed through an LCD panel. The prism structures and/or diffractive elements can be spaced on an optical film to enable at least a portion of the light travelling through the LCD panel to pass through the optical film without being redirected. Various types of prism structures and/or diffractive elements can be used, and they can be configured on the optical film differently to enable different functionality.

Abstract: An assembly structure and method for an integrated laser/detector device with a mirror at an angle to redirect the laser beam to a medium. The mirror is not attached to the circuit board with the laser/detector as in the prior art, but rather is mounted separately in the housing immediately above the circuit board. This allows the circuit board to be moved laterally toward and away from the mirror during assembly to adjust the reflected beam along a first direction so that it contacts the photodetector. A hologram lens is mounted above the mirror, and can be rotated to adjust the reflected beam to hit the photodetector along a second, orthogonal direction. In one embodiment, two laser beams are generated, and two hologram lenses are used to separately adjust the two beams.
