Abstract:
Disclosed is an optical film having an optical structure, such as a prism film or sheet, which is a constituent of a backlight unit. The optical film includes an optical structure layer having a plurality of optical structures, the surface of which is formed with irregularities, and the irregularities are formed on the surface of the light-collecting optical structure to satisfy predetermined conditions, thus effectively realizing a light-diffusing function, thereby eliminating the need to additionally mount a diffusion film or a protection film. When a particle dispersion layer is further formed on the surface of a transparent substrate opposite the surface having the optical structure layer, damage due to friction to prism films or other sheets may be prevented during the layering of the prism films or transport, thus obviating the use of a plurality of optical films.
Abstract:
Disclosed is an optical sheet having an optical structure, such as a prism film or sheet, which is a constituent of a backlight unit. In the optical sheet, protrusions are formed on the optical structure layer, and thus light-collecting efficiency in a front direction is maintained, and a function of diffusing light to the front or the inclined surface is also exhibited, thus eliminating the need to additionally mount a diffusion film or a protection film, thereby obviating the use of a plurality of optical films, consequently making it possible to economically manufacture a backlight unit with improved productivity.
Abstract:
Disclosed herein are a washing machine and a sound control method thereof that are capable of canceling noise generated during an operation of the washing machine and, at the same time, informing a user of information related to the operation of the washing machine using a sound. The sound control method includes operating the washing machine according to an inputted operation command, sensing noise generated during the operation of the washing machine, reading a sound to cancel the sensed noise, and outputting the read sound in a state in which the read sound is mapped with the noise. Consequently, it is possible mask the noise, thereby minimizing the noise. Also, it is possible to sense a start and an end of each operation and a change of the operation based on the noise pattern, sense a user's access to the washing machine, and output a feedback sound, thereby informing of the progress information of the washing machine.
Abstract:
Disclosed is a liquid crystal display (LCD) device equipped with a resin black matrix, capable of preventing the light leakage phenomenon by improving an OD (optical density) value of the resin black matrix. The LCD device includes an array substrate formed with a thin film transistor and a pixel electrode, a color filter substrate aligned opposite to the array substrate and formed with a resin black matrix and a color filter, a liquid crystal layer aligned between the array substrate and the color filter substrate, and lower and upper polarizing plates attached to outer surfaces of the array substrate and the color substrate and having transmission axes extending in the same direction. The resin black matrix has a transmission axis perpendicular to the transmission axes of the lower and upper polarizing plates so that the resin black matrix has a polarizing function.

Disclosed herein are a plastic microchip used in counting the number of microparticles and including direction indicators and a method for manufacturing the same. The plastic microchip includes a negative microgrid pattern formed on a lower substrate and direction indicators indicating the position of the microgrid pattern and formed in the vicinity of the microgrid pattern. The method for manufacturing the plastic microchip includes injection-molding a lower substrate including a negative microgrid pattern and direction indicators formed in the vicinity of the negative microgrid pattern, and injecting a solvent through solvent inlets so as to fix an upper substrate to the lower substrate. Accordingly, the present invention provides a plastic microchip including the direction indicators indicating the position of the microgrid pattern and formed on the lower substrate so that an observer can readily find the microgrid pattern through a microscope, thus facilitating the observation of a sample.

Abstract:
Golf ball covers incorporate base material compositions including a sound-altering material for selectively enhancing or dampening the acoustic output of a golf ball when it is struck. A ratio in the composition by weight of base material to sound-altering material ranges between 99.9:0.1 and 92:8. The invention allows for the altering of the sound of the golf ball while retaining the mechanical properties of the golf ball cover.

The invention relates to the field of shoes in general, and more specifically to the application of microspheres in shoe material formulations to yield desired shoe properties. Even more specifically, the invention relates to a shoe component prepared from a closed cell foam incorporating microspheres to yield controlled cell size, cell size distribution and expansion characteristics. In another embodiment, the invention also relates to an inner sole for a shoe prepared from the reaction product of a polymer matrix component and a curing agent where the curing agent is incorporated in microspheres to yield a material conformable to the user's foot shape.
Abstract:
A golf ball core incorporates a cobalt-catalyzed polybutadiene rubber falling within particular specifications for various material values. The material allows for manufacture of a core having a desirable coefficient of restitution and compression properties, while also exhibiting ease of processing. The core also can incorporate a high-cis content, high viscosity polybutadiene rubber to further enhance its coefficient of restitution and compression properties, while maintaining good ease of processing.
