Abstract:
A optical element covering member includes one or more optical elements, a support medium for supporting the one or more optical elements, and a cover material for covering the one or more optical elements and the support medium. The cover material includes a layer of block copolymer of vinyl aromatic hydrocarbon and conjugate diene, and a mass ratio of the vinyl aromatic hydrocarbon to the conjugate diene stands at 95:5 to 5:95.
Abstract:
An optical element comprises at least one optical film wherein at least a portion of the optical film is maintained dimensionally stable by the presence of a mechanism for application of a controlled tensile force to the film wherein the tensile force is applied through a tensioning mechanism protruding through holes or slots in the optical film.
Abstract:
A backlight assembly having improved strength and a display device having the backlight assembly are provided. The backlight assembly includes a light source supplying light and a fixing member receiving the light source. A deflection preventing portion having a predetermined width is formed on a surface of the fixing member in a direction crossing a diagonal on the surface of the fixing member.
Abstract:
The backlight module in the flat panel display (FPD) includes a frame that resides between the backlight module and the cover of FPD display, and has an inclined plane with an angle between the optical film. The inclined plane causes the touching area broader than the parallel plane does, thus it will absorb more stress force and avoid displaying defects in the FPD panel. Using this structure, the pressure transformed from the FPD cover stresses the inclined plane and forces it to contact the FPD's back light module on broader area in reducing the pressure per unit's area.
Abstract:
A liquid crystal module includes an annular casing molded from resin, a diffuser panel attached to a front side of the casing, a liquid crystal cell disposed on the front side of the casing so as to close a front side of the diffuser panel, and a substrate attached to a rear side of the casing. The casing has a through hole that is formed on an outer peripheral portion of the casing, and a catch formed at a front end of the through hole. The diffuser panel closes the through hole from the front side of the casing. The substrate is attached to the rear side of the casing to close the through hole from the rear side. It is possible to prevent outside dust from entering into the space between the liquid crystal panel and the diffuser plate through the through hole.
Abstract:
A portable display device is provided. The portable display device includes a liquid crystal display panel for displaying an image, a back light assembly having a light source for supplying light to the liquid crystal display panel, and a bottom chassis for supporting the back light assembly. The sides of the bottom chassis have an I-beam shaped or C-beam shaped cross-section.
Abstract:
A polarizer used for an image display such as a liquid crystal display, a plasma display, and an electroluminescence display, and the polarizer suppresses coloring of transmitted light. The polarizer includes a polymer film having a difference of 10% or less between the maximum and the minimum of a first transmittance in a wavelength ranging from 400 nm to 700 nm.
Abstract:
A liquid crystal display panel device has a backlight unit for illuminating the reverse surface of a liquid crystal display panel, and the backlight unit includes a diffusion plate, a diffusion sheet adhered to one of the major surfaces of the diffusion plate, a lamp house and a moisture-proof sheet inserted between the other surface of the diffusion plate and the lamp house; the moisture-proof sheet prevents the diffusion plate from vaporization of water contained in the diffusion plate, and the diffusion plate is not warped; the diffusion plate maintains the initial shape immediately after the assemblage into the backlight unit so that the liquid crystal display panel is continuously uniformly illuminated by the backlight unit.
Abstract:
A liquid crystal display device includes a liquid crystal panel, at least one optical sheet substantially rectangular in shape, where first and second openings are formed on the end edges of one side of the optical sheet at a predetermined interval, a main frame in which the optical sheet(s) are placed, and a sub-frame arranged above the main frame, in which the main frame is provided with first small protrusions jutting upward corresponding to the first openings at the top surface, while the rear surface of the sub-frame is provided with second small protrusions jutting downward corresponding to the second openings, thereupon the first small protrusions are inserted into the first openings of the optical sheet(s) and the second small protrusions are inserted into the second openings to connect and install the sub-frame to the main frame, and the optical sheet(s) are then aligned and fixed. Accordingly, the optical sheets are aligned better and firmly fixed to achieve larger display screens and thinner liquid crystal display devices.
Abstract:
The present invention provides a polarizing film or a polarizer that has an elastic modulus of at most about 3500 N/mm2 and suppresses occurrence of warping, the polarizing film is obtained by adsorbing a dichroic material in a polyvinyl alcohol-based film 20 μm in thickness and stretching the tilin. The polarizing film has a transmittance of at least 43% and a polarization degree of at least 98%. A transparent protective layer is laminated on at least one surface of the polarizing film to form a polarizing plate.
