  • Publication number: 20060214873
    Abstract: A multi-display (e.g., dual-display) driving circuit includes a first display driving circuit configured to receive a first display signal and a second display signal from an external source (e.g., CPU) through a first interface, and to drive a first display panel in response to the first display signal and to output the second display signal through a second interface of the first display driving circuit. The second display signal is transmitted via the second interface to a second driving circuit configured to drive a second display panel. Therefore, the complexity of the wiring (e.g., through a hinge of a folding phone, and between a CPU and first and second displays) of the multi-display device may be reduced, and the electromagnetic interference (EMI) characteristics of the multi-display device may be enhanced.

  • Publication number: 20040213445
    Abstract: An object separating method separates a target object from an ultrasound image. Specifically, first of all, a set of two dimensional (2D) ultrasound images are combined to provide volume data. Then, a rotational axis to rotate the volume data and two points as reference points are set, wherein the two points are points where the rotational axis and the target object intersect. Thereafter, the volume data is rotated by a predetermined angle around the rotational axis to generate a 2D ultrasound image for each rotated angle, wherein the rotating process is repeatedly performed until the volume data is rotated by a preset angle. A contour of each 2D ultrasound image is extracted and vertices on the contour are set to thereby provide contours with vertices. The vertices of each of the contours are wired and processed to provide a 3D image of the target object.

  • Patent number: 6483162
    Abstract: A semiconductor device having improved metal line structure has a first dielectric layer formed on a semiconductor substrate, a metal film pattern formed on the first dielectric layer, an interface protection layer on the metal film pattern, and a second dielectric layer on the interface protection layer, wherein the second dielectric layer contains a reactive material, e.g., fluorine, which is prevented by the interface protection layer from diffusing to the metal film pattern and reacting with the metal in the metal film pattern to form a damage film, e.g., metal fluoride, which is a highly resistive material that, if formed on the semiconductor device, would reduce the reliability of the metal film pattern and thus reduce the reliability of the semiconductor device as a whole.
