Abstract:
A plasma display panel (PDP) has an exhaust pipe protruding from a panel assembly, a chassis base mounted on one side of the panel assembly to support the panel assembly such that the exhaust pipe protrudes through a hole formed in the chassis base. A reinforcement structure is mounted on the chassis base to fortify the chassis base and to prevent torque and bending of the panel assembly. A protection structure is designed to form a space to enclose the exhaust pipe to prevent damage to the exhaust pipe. The protection structure is formed to be integral with the reinforcement structure.
Abstract:
A display device is provided including a display panel for displaying an image, the display panel having substrates and electrodes located between the substrates. The display device also includes a chassis base supporting the display panel and a plurality of printed circuit board assemblies mounted in the chassis base for driving the display panel. One of the printed circuit board assemblies is an address buffer board assembly driving an address electrode, the address buffer board assembly including a flexible printed circuit connected to the address electrode. The flexible printed circuit has a terminal surface corresponding to a width of a terminal drawn from the address buffer board assembly.
Abstract:
An external light blocking film includes a base transmitting external light, and an external light blocking pattern which blocks the external light and is formed at the base. A refraction index of the base is larger than a refraction index of air by more than 0 and not more than 0.56. The base satisfies the following equation: 0°
Abstract:
A method for manufacturing plasma display panels (PDP) is disclosed. The method appropriately controls conditions in an evaporating room during the process of forming film on a substrate of the PDP, thereby obtaining quality film. The method includes a deposition step where film is formed on front substrate (3) held by substrate holder (30), which is repeatedly used in the deposition step. Substrate holder (30) attached with the film due to repeated use co-exist in evaporating room (21) with another substrate holder (30), from which the film attached is removed, so that the conditions such as a degree of vacuum changes only a little.
Abstract:
Electromagnetic Interference (EMI) shields for a direct-view display having a direct-view display panel and an outer panel that provides an outer surface for the direct-view display. These EMI shields include a conductive mesh having an array of gaps therein. The conductive mesh is configured to shield at least some of the EMI that is emitted by the direct-view display panel. An optical redirecting structure is also included, that is configured to redirect at least some optical radiation that is emitted from the direct-view display panel that would strike the conductive mesh, through the gaps in the conductive mesh. The EMI shield is configured to mount between the direct-view display panel and the outer panel such that the optical redirecting structure is adjacent the direct-view display panel and the conductive mesh is remote from the direct-view display panel.
Abstract:
An optical sheet and a display optical filter which can increase a contrast ratio in a bright room are provided. The optical sheet for the display optical filter includes a transparent substrate including a plurality of pattern grooves formed thereon; and a light shielding pattern formed of a light absorbent material filled in the plurality of pattern grooves. The light shielding pattern may be formed of a material for either absorbing or shielding light filled in the plurality of pattern grooves. In particular, when an external illuminance increases from 0 Lux to 250 Lux, a reduction rate of a color gamut in CIE color coordinates may be 9% or less with respect to NTSC, and the reduction rate of the color gamut is relatively less in comparison with the case where the optical sheet of the present invention is not used.
Abstract:
A plasma display panel and the manufacturing method thereof. Forming partition wall structures on the back substrate of the paste display panel and forming the column-shaped protrusions at the positions corresponding to the cuts on the rib on the front substrate of the plasma display panel. The manufacturing process is simple and the alignment of the front and back substrate is easy. In addition, the size of the opening of the rib and the size of the cut can be easily adjusted according to the needs of the application during the manufacturing process.
