Abstract:
A plasma display panel. A first substrate and a second substrate are provided at a predetermined distance from the first substrate and form a vacuum assembly with the first substrate. Barrier ribs form pixels between the first substrate and the second substrate such that subpixels forming one grouping of pixels are arranged in a triangular configuration. A plurality of address electrodes is formed on a surface of the first substrate facing the second substrate and along a first direction of the first substrate. A plurality of discharge sustain electrodes is formed on a surface of the second substrate facing the first substrate and along a first direction of the second substrate. A phosphor layer and a discharge gas are provided between the first substrate and the second substrate. If a length of a line passing through a center of the subpixels and interconnecting two opposing corners of the subpixels is (c), and if a length of a line extending between two adjacent corners is (b), the subpixels are formed such that a (b) to (c) ratio is between 1:1.5 and 1:5.

The photography apparatus includes an image sensor, and a control unit which divides an area of the image into a first area and a second area using brightness information of the acquired image, and controls so that a first row group and a second row group of the second area have different exposure times. As a result, an image with a wider dynamic range is provided.
Abstract:
An X-ray device is disclosed. In one embodiment, the device includes an X-ray detector and a power contactor which includes a contact terminal. The device may further include an X-ray table that provides a space into which the X-ray detector is inserted and that includes a push pin pressing the power contactor, wherein the power contactor selectively protrudes from the inside to the outside of the X-ray detector due to a pressure applied by the push pin, and the contact terminal is electrically connected to a power terminal of the X-ray table. The X-ray detector prevents exposure of the power contactor to the outside thereof when the X-ray detector is carried or transported and thus prevents a malfunction of the X-ray detector.

Abstract:
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. Some embodiments also include an intermediate electrode disposed between the scanning and sustain electrodes. Embodiments of the disclosed plasma display panel exhibit a reduced voltage drop over the transparent electrodes of the sustain electrodes and scanning electrodes, thereby permitting the generation of a sustain discharge at a lower voltage, and a reduced time for generating an address discharge light.
Abstract:
A plasma display panel (PDP) with improved bright room contrast while achieving a high opening ratio and high luminance. The PDP includes display electrodes that includes auxiliary electrodes that suppress reflection of incident light off the discharge cells. With address electrodes formed on the rear substrate and the display electrodes formed on the front substrate, auxiliary electrodes connect pairs of display electrodes together. The auxiliary electrodes and the main bus electrodes extend into the discharge cells and reflect the external light. The opaque main bus and auxiliary electrodes are combined with a transparent electrode portion that overlies the main bus and the auxiliary portions to form the display electrodes.
