Abstract:
A plasma display panel having improved exhaust efficiency is disclosed. A plasma display panel according to a first embodiment of the invention includes first and second substrates opposing each other; barrier ribs that are located in a space between the first substrate and the second substrate for dividing a plurality of discharge cells in sealed spaces; display electrodes located along the discharge cells; and address electrodes formed in a direction intersecting the display electrodes. The barrier ribs include first barrier ribs having a first height and second barrier ribs having a second height so that the difference in height between the two ribs is provided.
Abstract:
A plasma display panel may include a first substrate and a second substrate arranged opposing each other, band-shaped first and second electrodes disposed between the first and second substrates and third electrodes disposed between the first and second substrates while extending in a first direction. Barrier ribs may be disposed between the first and second substrates. The barrier ribs may be spaced apart from each other in a second direction intersecting the first direction to define column spaces that extend in the first direction, the column spaces having wider portions and narrower portions alternately, the wider portions corresponding to discharge spaces. The first and second electrodes may cross the barrier ribs and protrude inside the discharge spaces such that the first and second electrodes form discharge gaps in each discharge space.
Abstract:
A plasma display panel includes first and second substrates spaced apart from each other, barrier ribs partitioning the space between the first and second substrates into a plurality of discharge cells, at least one first electrode extending in a first direction, and at least one second electrode extending in a second direction crossing the first direction, wherein the second electrode includes a principal electrode and an auxiliary electrode intersecting the principal electrode.
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.
Abstract:
Provided is a waveguide system for an electrodeless lighting device, comprising a waveguide guiding microwave energy outputted from an antenna of a microwave generation means which is fixedly-inserted into an inner surface of the waveguide, and having a slot formed at an inner surface of the waveguide and communicated with a resonator where a bulb is positioned for supplying the microwave energy inside the resonator, a first stub protruded from one inner surface of the waveguide to be placed adjacent to the slot, for an impedance matching with the antenna and tuning with an output frequency of the antenna; and a second stub protruded from an inner surface of the waveguide at a certain interval with the first stub and extending a bandwidth together with the first stub for tuning with the output frequency of the antenna is varied according to an impedance variation of the antenna, thereby enabling a supply of a maximal microwave energy outputted from an antenna to the resonator, and assuring of a resonance stability.
Abstract:
A digital modulation apparatus and method used for a DVD-RAM and a DVD-R/RW and for increasing the margin of an operation of an external device is provided. The digital modulation apparatus includes a 4-stage pipeline and includes a mode selection unit, a field enabling signal generation unit, a data fetch and sync code generating unit, an eight-to-fourteen modulation plus (EFMplus) conversion unit, and a non-return-to-zero inverted (NRZI) conversion unit. The mode selection unit generates a mode selection signal for selecting one from a DVD-RAM operation mode and a DVD-R/RW operation mode in response to a control signal. The field enabling signal generation unit selectively generates recording field enabling signals related to a DVD-RAM, or selectively generates recording field enabling signals related to a DVD-R/RW, in response to a start signal and the mode selection signal and provides the recording field enabling signals to the data fetch and sync code generation unit. The data fetch and sync code generation unit fetches 8-bit data words, generates sync codes, and performs an operation for fetching the data words and an operation for generating first sync codes in parallel. The EFMplus conversion unit converts the 8-bit data words output from the data fetch and sync code generation unit into M-bit (where M is an integer) first code words and then, converts the converted first code words into 16-bit second code words. The NRZI conversion unit converts the second code words into a NRZI signal.
