摘要:
A discharge lamp is disclosed, including a sealed vessel with an inner surface, at least one illuminating gas filled inside the sealed vessel, and a fluorescent layer coated on the inner surface. The composition of the fluorescent layer is adjusted according to a colored light emitted by the illuminating gas during a discharge process within the sealed vessel, such that the colored light is converted into a visible light after passing through the fluorescent layer.

An AC plasma display panel of the present invention changes the conventional disposition of three electrodes. Either the scanning electrode or sustaining electrode is disposed in the rib or on the sidewall of the rib. Also, two scanning electrodes both use the same sustaining electrode disposed on the rib. Thus, a high resolution and high precision AC plasma display panel can be obtained.

Silicon containing copolymers are mixed with diazonaphthoquinone esters to give UV photoresists for use in microlithography on integrated circuits (IC). The copolymer structure has a thermally resistant group, N-(4-hydroxyphenyl)maleimide, and an oxygen plasma resistant group, para-trialkylsilylstyrene.

A plasma display device is disclosed. The plasma display device has a first panel and a second panel parallel to each other. A dielectric layer is formed on the second panel, a plurality of barrier ribs are formed on the dielectric layer, and a plurality of buffer layers are formed opposite to the barrier ribs. The buffer layers have a first softening temperature, the barrier ribs have a second softening temperature, and the first softening temperature is lower than the second softening temperature. The buffer layers can be deformed and compressed at a temperature higher than the first softening temperature during a process for sealing the first and second panels, so as to unify heights of the barrier ribs.

A front plate for a plasma display panel (PDP) and its modified fabricating method are provided using a backside exposure process and an appropriate processing sequence rearrangement to reduce the number of photomasks required and improve the accuracy of exposure and developing process. First, a light-shielding layer is patterned by performing a mesh printing process, or by performing an exposure and developing process using a first photomask, so as to form a light-shielding structure including black stripes and transparent electrodes' gaps. Next, using the light-shielding structure as a mask, a backside exposure and developing process as well as an etching process is performed to form a plurality of pairs of transparent electrodes on the substrate. Then, using a second photomask, another set of exposure, developing and etching processes are performed to form a plurality of pairs of metal electrodes on the corresponding transparent electrodes.
摘要:
For the manufacture of a color screen for a cathode ray tube a process is described which uses a single photolithographic mask for defining multiple patterns, so that said single mask may be used for determining the different areas where several different phosphor layers will be located. Masks used for conventional photolithographic processes normally comprise a pattern of regions that are either fully transparent or fully opaque to the radiation used for exposing the resist. The mask used as part of the present invention includes regions that are neither fully transparent nor fully opaque, having, instead, a grey scale of optical densities. Through careful control of both exposure and development time, selected parts of a layer of a positive photoresist, that were exposed through successively denser regions of the mask, can be successively removed. As each of these parts of the resist is removed, parts of an underlying layer of adhesive are uncovered and then serve as selective sites for the application of phosphor particles. The process may be used with or without the inclusion of a black matrix as part of the structure.
摘要:
A process is described for the manufacture of a luminescent screen that eliminates image distorting or crosstalk effects resulting from secondary and back-scattered electrons that end up in adjoining sub-pixels. An unusually thick (ca. 70 microns) black matrix is first formed on the substrate surface and is given a tapered cross-sectional shape such that it is smaller at its top surface than at the substrate surface. Said tapered profile may be achieved through a screen-on process or by an overetching process. This is followed by the deposition of a transparent conductive layer, such as ITO, onto which the various layers of different phosphors that make up the sub-pixels of the display are deposited by means of electrophoresis.
