  • Publication number: 20170285771
    Abstract: An active stylus pen is insensitive to external noise and has enhanced sensing performance with respect to an uplink signal input from a touch screen. The active stylus pen includes a housing connected to a ground, a conductive tip protruding outwardly from one side of the housing and brought into contact with a touch screen, a conductor layer surrounding an outer surface of the housing with an insulator interposed therebetween, a pen driving circuit connected to the conductor layer, and a switch connecting the conductor layer and the pen driving circuit. The pen driving circuit is cased by the housing, receives an uplink signal and a touch sensor driving signal from the touch screen, generates a pen driving signal synchronized with the touch sensor driving signal and outputs the generated pen driving signal to the touch screen through the conductive tip.

  • Patent number: 9543371
    Abstract: A transparent organic light-emitting display device is described herein. The transparent substrate includes a display area and non-display area adjacent to the display area. An organic light-emitting element is disposed on the display area of the transparent substrate. A first power line is disposed on the display area of the transparent substrate. The first power line supplies power to the organic light-emitting element. A first circuit board comprises a first power supply provided on a first side of the transparent substrate and a second circuit board comprises a second power supply provided on a second side of the transparent substrate. The first power supply is configured to receive power from the second power supply via the first power line. An additional interconnection film to supply power to the first power supply is not required, and thus the width of the bezel can be reduced.
