Description

  The present invention relates to a protective plate used for a display unit of various portable terminals and a portable terminal using the protective plate.

In recent years, a large amount of various mobile terminals such as mobile phones and PDAs have been on the market, and these mobile terminals have been decorated with a wide variety of decorations on their outer casings for product differentiation. Furthermore, various decorations are similarly applied to the protective plate used in the display portion of the outer casing. As these decorated protective plates, for example, when a protective plate is manufactured by injection molding, a transfer foil on which a pattern or the like is printed is adhered in advance to the surface of the injection mold, and then in the mold. A protective plate formed by injection-extruding a resin from a predetermined position and transferring and decorating a transfer foil pattern on the surface of the protective plate at the same time as molding, or a sheet having a thickness of 0.5 to 1.2 mm There are products that have been subjected to partial vapor deposition processing in the post process and decorated, etc., but these products have unstable product quality after decorating and the yield of good products is bad, or the manufacturing process becomes large There are various problems such as high cost.
