Abstract:
In a light-guide module, a method of manufacturing the light-guide module and a backlight assembly having the light-guide module, the light-guide module includes a light-guide plate (“LGP”) and a thin-film layer. The LGP has a light-incident surface into which lights are incident and a light-exiting surface through which lights exit. The thin-film layer is formed on the LGP. The thin-film layer has a concavo-convex pattern formed on an opposite surface of a surface contacting the LGP. Accordingly, a thin-film layer having a concavo-convex pattern is formed on a light-incident surface of an LGP, so that a reflectance of light incident into the LGP may be decreased. Moreover, a light amount transmitted through the LGP is increased in accordance with a decreasing of reflectance, so that a light transmittance may be increased in total.

A C+N austenitic stainless steel with high mechanical strength and excellent corrosion resistance and a fabrication method thereof are provided. The C+N austenitic stainless steel consists of: 8 to 12 wt. % manganese; 15 to 20 wt. % chromium; 2 wt. % or less nickel; 4 wt. % or less tungsten; 2 wt. % or less molybdenum; 0.6 to 1.0 wt. % of total C+N content; a balance of iron; and unavoidable impurities. The austenitic stainless steel fabricated provides mechanical properties of a tensile strength of 850 MPa or higher and an uniform elongation of 45% or higher, obtained through controlling the contents of the interstitial elements and those of the substitutional elements. The alloy also provides corrosion resistance and a biocompatibility due to the minimized content of nickel which causes allergic reaction to the human body. Therefore, the C+N austenitic stainless steel is applicable in the fabrication of a variety of functional components and structural fields.

A plasma display panel including address electrodes extending in a first direction, and scanning and sustain electrodes extending in a second direction, the electrodes corresponding to discharge cells. Each of the scanning and sustain electrodes includes a transparent electrode that extends toward the other of the scanning and sustain electrode, and over the discharge cell; a main bus electrode positioned adjacent to and parallel with a barrier rib member; and a sub-bus electrode disposed between the main bus electrode and the other of the scanning and sustain electrode.
