摘要:
In a PDP back surface plate comprising substrate and a rib pattern layer formed on the substrate and having a rib region that has ribs having a predetermined shape and a predetermined size, and a non-rib region that occupies at least a part of a peripheral portion of the rib region, a thin film made of the same material as that of the ribs is formed to a predetermined thickness in the non-rib region.
摘要:
A flexible mold (10) having a mold layer (11) that is provided on the surface thereof with a groove pattern (4) of specified shape and size, is constructed such that the mold layer contains a lithium salt of an organic fluorine compound as an antistatic agent.
摘要:
This invention relates to a molding technology. More particularly, the invention relates to a flexible mold, its production method and a production method of a fine structure. The invention can be utilized for the production of various fine structures such as barrier ribs of a back plate of a plasma display panel.
摘要:
An article comprising a microstructured surface, wherein the microstructures compris the reaction product of a of a polymerizable composition comprising at least one oligomer or monomer that comprises at least two (meth)acrylate groups and at least one monofunctional (meth)acryl monomer and the reaction product has a glass transition temperature of less than 35° C.
摘要:
A method of producing a substrate (12) for a plasma display panel, which comprises the steps of: contacting a rib precursor composition (32) containing a first photo-setting initiator having a first absorption edge and a first photo-setting component, closely with a base (12); filling a mold (30), obtained by photo-setting of a second photo-setting component in a presence of a second photo-setting initiator having a second absorption edge whose wavelength is shorter than that corresponding to the first absorption edge of the first photo-setting initiator, with the rib precursor composition (32); irradiating the rib precursor composition (32) with light having a wavelength longer than that corresponding to the second absorption edge to set the rib precursor composition (32), thereby forming a rib (34) on the base (12); and removing the mold (30) from the resulting base (12) on which the rib (34) is formed.
摘要:
A method of forming microstructures on a substrate is disclosed. A microstructured assembly that may be used in the method for forming microstructures on a substrate is also disclosed. The methods and assemblies of the present disclosure can reduce the amount of air entrapped in barrier ribs formed on substrates used in Plasma Display devices.
摘要:
A method and master mold (10) comprising a metal support layer (1) and a fine structure pattern (4) comprised of a glass or ceramic material, wherein the pattern support layer is formed of a first material having a relatively low grinding speed, and the fine structure pattern is formed of a layer of a second material having a grinding speed higher than that of the material of the pattern support layer.
摘要:
A method of producing barrier ribs for a plasma display panel substrate, which comprises the steps of: (a) partially filling a groove portion of a mold with a first photosensitive glass-ceramic paste selected from a photosensitive black glass-ceramic paste and a photosensitive white glass-ceramic paste, and curing the paste by irradiating with radiation; (b) supplying a second photosensitive glass-ceramic paste, which is different from the first photosensitive glass-ceramic paste, selected from the photosensitive black glass-ceramic paste and the photosensitive white glass-ceramic paste, on a glass base, and laminating the mold with the glass base through the second paste to form a laminate; (c) irradiating the laminate with radiation to form a rib precursor molded article composed of two white and black layers; (d) removing the mold from the glass base and the rib precursor molded article to transfer the rib precursor molded article to the glass base; and (e) sintering the rib precursor molded article to form a rib formed integrally on the glass base.
摘要:
An apparatus is provided for producing a substrate for PDP, which can easily reduce ununiformity of a dielectric layer and defects of ribs. The apparatus is so constituted that it comprises: a table for the plate, a rib precursor supplying portion for providing a precusor of the ribs on the plate, a pliable mold having at least groove portions provided in parallel with each other at a fixed distance, which is disposed on the precursor of the ribs provided on the plate, a mold pressing portion for applying a pressure to the mold, thereby to contact the mold closely with the plate via the precursor of the ribs, and a driving portion for moving the mold pressing portion along the groove portions of the mold.
