摘要:
A light guide member for guiding light received from a light source unit, the light source unit illuminating light toward the light guide member, the light guide member may include a first groove on a first side of the light guide member, wherein at least one of a first width and a first depth of a first portion of the first groove may be different from a second width and a second depth of a second portion of the first groove based on a respective radiation angle of the light illuminating the first portion and the second portion of the light guide member.
摘要:
A system and method for producing a plurality of controlled surface irregularities, such as wrinkles, is provided. The system includes a polymeric substrate. An irradiation source is positioned to provide a beam on desired areas of the polymeric substrate. The surface irregularities appear on the exposed region by controlling the relative motion of the polymeric substrate and the irradiation source when scanning the exposed region.

Provided is a method of preparing styrene polymers, the method comprising: homogeneously mixing a styrene monomer; a cocatalyst mixture of Group 13 metal-containing organic metal compound cocatalyst and an inert organic solvent; and a catalyst mixture of a metallocene catalyst and the inert organic solvent using a high speed homogenizing mixer to obtain a homogenized mixture; and providing the homogenized mixture to a reactor to initiate polymerization. In this method, catalyst is quickly dispersed among monomers using a high speed homogenizing mixer so that formation of gel, which occurs when a syndiotactic styrene polymer is produced, can be fundamentally prevented. In addition, a styrene polymer prepared using the method has high activity, good stereoregularity, and uniform molecular distribution.
摘要:
A liquid crystal display (LCD) apparatus and method for automatically sensing and compensating a delay time of a gate signal fed to the LCD display panel. The LCD panel includes a signal converter for generating a power clock signal, a delay controller for generating a delay control signal corresponding to the delay value of the gate signal by comparing the power clock signal with a signal derived from the data lines, and a pixel voltage signal generator for supplying a pixel voltage signal to the data lines of the LCD panel in response to the delay control signal.
