  • Patent number: 12216305
    Abstract: A front light module includes a light guide sheet and a light bar. The light guide sheet has two light receiving laterals, a fold line, a first pattern area, and a second pattern area respectively located on two sides of the fold line. One light receiving lateral is protruded to form first taper sets, and the other is protruded to form second taper sets. The second pattern area is superimposed on the first pattern area, and the first and second tapers set are engaged and coplanar to form a light incident surface after folding along the fold line. The light bar provides light toward the light incident surface, the first pattern area is lit by the odd positions of the light bar via the first taper sets, and the second pattern area is lit by the even positions of the light bar via the second taper sets.

  • Patent number: 10775900
    Abstract: A light guide plate provided for a luminous keyboard is disclosed. The light guide plate includes a main body, a first bump pair, a second bump pair, and many microstructure patterns. The main body has a light output surface and many press button installation areas defined thereon, each of the press button installation areas is arranged to fix a press key structure. The first bump pair and the second bump pair are integrally and seamlessly protruded from the main body. Each of the first bump pair has a first recess, and each of the second bump pair has a second recess. The first recess and the second recess are configured opposite to each other, and provided for assembling the press key structure. The microstructure patterns are formed next to the first and second bump pairs to abstract light by destructing the total reflection in the main body.

  • Publication number: 20120195550
    Abstract: The present invention discloses a method of making an optical microstructure patterns on a light guide plate, a light guide plate thereof and a imprinting mold. The method of making the optical microstructure patterns on the light guide plate includes a step of bombarding the surface of a substrate to form a micro notch thereon by laser, in which the periphery of the micro notch has as at least a protrusion, and a step of bombarding the protrusion to at least downsize the protrusion by another laser.

  • Publication number: 20120113013
    Abstract: A keyboard comprises a key module and a backlight module in which the key module comprises a light-transmissive key part and an electric circuit substrate, and the backlight module comprises a light guide plate, a reflection unit and at least one light source. The backlight module is disposed between the key part and the electric circuit substrate. Thus, lights emitted by the light source are projected into the light guide plate from the lateral side of the light guide plate, and the lights are reflected by the reflection unit for directly passing through the light output surface of the light guide plate and the key part.

  • Publication number: 20120081920
    Abstract: A backlight module provided includes a light source, a first light-guided plate, and a second light-guided plate stacked on the first light-guided plate. The first light-guided plate includes a plate body and an extension disposed on an edge of the plate body and extending towards the second light-guided plate aside a lateral side of the second light-guided plate. The plate body and the extension form a seamless light incident surface. The extension has a reflection surface. The reflection surface connects the light incident surface or the surface of the plate body. The light source is disposed at a light incident surface of the first light-guided plate for projecting light into the light-guided plate.

  • Publication number: 20120020055
    Abstract: A backlight module comprises a light emitting element and a light guide panel having a light output surface in which the light output surface is with a first side, a second side, a through hole, a recess and plural microstructure rows. The microstructure rows are arranged on the light output surface, and the extending direction thereof is parallel to the extending direction of the first side. The through hole is installed between any two adjacent microstructure rows. The light emitting element is disposed in the recess in a central zone of the light output surface, and arranged to emit lights towards the second side. One major light emitting axis of the light emitting element deviates from the through hole.
