  • Patent number: 6661399
    Abstract: A liquid crystal display (LCD) device having a digitizer. A liquid crystal panel is supported by a lower frame having a side wall portion. A digitizer is located on the liquid crystal panel. An upper frame having a front surface with an opening region and a side wall portion is located over the digitizer such that the tipper frame pressurizes a peripheral portion of the digitizer. The opening region is formed at a location corresponding to the display region of the liquid crystal panel. The upper and lower frames mate to hold the liquid crystal panel and the digitizer in place. The upper frame is beneficially metallic to provide electrical shielding of conductors on the digitizer. Common electrical circuits are shared by the digitizer and the liquid crystal panel.

  • Publication number: 20020154099
    Abstract: A protector for a wired/wireless data transmitting/receiving terminal and a wired/wireless data transmitting/receiving terminal having the same. The protector prevents a display or a touch screen from getting damaged while maintaining characteristics and commercial value of the terminal employing a digitizer (touch screen) as a display or input device. A data transmitting/receiving terminal comprises a sheet protector installed on a display or a touch screen of a terminal bodyand includes a support band capable of attaching the sheet protector as a complementary structure to one end at regions at least excluding a display area. The protector includes a support band supported or attached to the support band of the terminal body and extends from the support band so as to cover the display and the touch screen. The invention can be applied to a protector for a display.
