Abstract:
A process for producing an article with a microstructure includes the steps of forming a primary relief structure on a surface of a substrate, applying a photo resist on the substrate, exposing part of the photo resist using a photo mask so as to form a microstructure pattern, developing the microstructure pattern in the exposed photo resist, thereby allowing access to a part of the primary relief structure from the photo resist, and thereby forming a patterned surface with a microstructure relief that is bounded by the exposed part of the primary relief structure and by remainder of the photo resist on the substrate, and forming a metal layer on the patterned surface to form the article having the microstructure with a profile corresponding to the microstructure relief on the patterned surface.
Abstract:
A lighting apparatus is disclosed. The lighting apparatus comprises a casing, at least one light source and a microstructure cover. The light source is disposed on one side of the casing. The microstructure cover is mounted on the casing opposite to the reflective face thereof. The microstructure cover has a plurality of guiding micro-structures to guide light and a plurality of dispersing micro-structures to disperse light.
Abstract:
The light guide plate has a flat body. At least one of the light emission plane and the light reflection plane of the light guide plate has a number of linear reflection structures arranged in parallel along the surface. The reflection structures have a V-shaped cross section pointing outward from or inward into the surface. Each reflection structure further has at least one of its end surfaces slanting towards the other end. It is the reflection structures' slant end surfaces that provide additional collimation and enhancement to the light beams traveling through the light guide plate.

A color cathode-ray tube having a good quality of display screen in which a fluorescent dot pattern is formed to have good configuration and positional accuracies. A method for manufacturing the display screen for the cathode-ray tube wherein a correction lens is formed with a plurality of fine adjacent planar or curved faces to cause uniform generation of a line width of latticed light/dark lines and a contrast thereof generated by level differences between the adjacent planar or curved faces when subjected to irradiation of exposure light all over a light exposure surface, the exposure light passed through the correction lens during vibration of the correction lens is directed through a shadow mask on a fluorescent film of an inner surface of a face panel of the cathode-ray tube for uniform irradiation thereof of the fluorescent film, the fluorescent dot pattern is formed on the inner surface of the face panel with the light-exposed fluorescent film used as a mask, whereby the fluorescent dot pattern having good configuration and positional accuracies is formed on the inner surface of the face panel, the display screen is formed with the fluorescent dot pattern having pixels of 1,000,000 or more and has a luminosity fluctuation factor of .+-.0.15% or less.
Abstract:
A frame structure for backlight modules is provided herein. A backlight module according to the present invention mainly contains a frame structure, a reflection plate, a light guide plate, optical films, and a light source unit. The frame structure contains a plate member and a frame member. There are a number of hook elements and clasp elements configured at corresponding locations along the edges of the plate member and the frame member respectively. Also along the edges of the plate member and frame member, there are a number of grooves and stopping blades configured at corresponding locations on the plate member and frame member respectively. When the frame member is joined to the plate member, their corresponding clasp elements and hook elements would interact to fixedly join together, and the stopping blades would stick into the corresponding grooves to prevent the frame member from deformation and escape under heavy pressure or strong impact.
Abstract:
A light guide plate (LGP) and LGP-based flat fluorescent panel (FFP) provides consistent light source for FFP to output consistent and high luminance light source for upgrading general light emitting efficacy to facilitate subsequent use of the light source by expanding incident angle for creating a scattering belt to destroy the total reflection of the light source passing through the scattering belt thus to avail better deflection to reduce light and shade stripes created in subsequent reflection.
