| 7282848 | Fluorescent lamp having phosphor layer that is substantially free from calcium carbonate A mercury vapor discharge fluorescent lamp is provided having a phosphor layer that has a yttria-based red emitting rare earth phosphor. The phosphor layer is prepared from an aqueous phosphor slurry that is coated onto the inner surface of the glass envelope of the... | 10/16/2007 |
| 7256541 | Organic light-emitting diode (OLED) and method for the production thereof An organic layer (1) is applied to a transparent carrier (2) in such a way that different partial regions with different refractive indices are formed in the layer. Owing to deflection at the phase boundaries within the layer, fewer photons remain trap... | 08/14/2007 |
| 7161297 | Electron emission thin-film, plasma display panel comprising it and method of manufacturing them An electron emission thin-film with improved secondary electron emission characteristics compared with conventional ones, a plasma display panel including the electron emission thin-film, and their manufacturing methods. Using a vacuum deposition system, a protectiv... | 01/09/2007 |
| 7112113 | Manufacturing method of display device A method for manufacturing a display device of the present invention includes the steps of forming insulating barriers which surround electrode and project upward from the surface of the electrode, and bringing the whole substrate into contact with water after apply... | 09/26/2006 |
| 6969292 | Method for forming phosphor layer of gas discharge tube and method for fabricating phosphor layer supporting member A phosphor layer is formed efficiently in a gas discharge tube by drawing a mother material to fabricate a supporting member which is insertable in a small glass tube used for a gas discharge tube, forming a phosphor layer on the supporting member, and inserting and... | 11/29/2005 |
| 4896074 | Process for marking a glass object and article A process of manufacture and an article produced by the process in the form of a lead glass substrate. The substrate is discretely marked during the manufacturing process by directing a flame upon it that is deficient in oxygen to provide a darkened or bl... | 01/23/1990 |
| 4745329 | Front assembly for an ultra-high resolution color cathode ray tube having an improved shadow mask compensated for diffraction and process therefor A color cathode ray tube is disclosed having a front assembly with a shadow mask characterized by having circular apertures at the mask center, and apertures at least in the mask periphery increasingly elongated radially outwardly as a function of distanc... | 05/17/1988 |
| 4534744 | Display panel and method of making it The method of making a display panel 10 comprising forming an assembly of a glass base plate having a set of longitudinal first slots in which anode electrodes are secured and having an array of cathode electrodes seated on the top surface of the base pla... | 08/13/1985 |
| 4407857 | Method for processing a lithium-sodium-antimony photocathode A method is provided for making a lithium-sodium-antimony photocathode including the step of forming a base layer including antimony on a substrate. Sodium is then deposited onto the base layer at an elevated temperature to a first peak value of responsiv... | 10/04/1983 |
| 4198106 | Method of manufacturing a photocathode for an image intensifier tube A photocathode internally processed image intensifier inverter tube includes a cathode housing having an outer side wall forming a cylindrical opening for connection to the photocathode of the inverter tube. The side wall forms a cylindrical cavity in whi... | 04/15/1980 |
