Abstract:
A method for aligning a plurality of thin film transistor tiles for constructing a flat panel display. A coverplate is arranged on a coverplate support. A first layer of a bonding material is applied to at least one of a first side of each of the tiles and a surface of the coverplate on which the tiles are to be secured. The tiles are arranged on the coverplate, such that the first layer of bonding material is arranged between the tiles and the coverplate. The tiles are connected to an alignment apparatus. The tiles are aligned relative to each other and the coverplate. The tiles are at least partially secured to the coverplate.
Abstract:
It is an object of the invention to present a disassembling method and disassembling apparatus for disassembling easily an electronic appliance having a housing, and electronic components such as cathode-ray tube accommodated in the housing, classifying without mixing of impurities, and recycling at low cost by automating. An electronic appliance having a housing, a cathode-ray tube, and plural electronic components is put on a conveying pallet, and it is transferred by a conveyor. The conveyed electronic appliance is put on a tiltable work bench, a back plate of the housing is removed, and an opening is formed. Blowing a high pressure air shower to the opening, dust deposits on the electronic components are removed and cleaned. Moreover, other side of the housing is processed into a U-form by end mill, and a further opening is formed, and the cathode-ray tube is taken out through this further opening. The metal band of the dismounted cathode-ray tube is heated by high frequency induction, and the metal band is removed. The adhesive applied on the cathode-ray tube is removed by using a rotary brush having metal wires. Still more, judging whether a safety panel is installed at the front side of the cathode-ray tube or not by using distance sensors, the safety panel is classified. Such disassembling process is executed by using an automated disassembling apparatus.

The invention provides a method for sealing arc tubes while preventing cracking of the tube. The method comprises sealing a pair of electrodes on the arc tube in a furnace. A heat shield structure is used to reduce the thermal gradient generated by the sealing process. The heat shield comprises alternating layers of thermally conducting materials and thermally non-conducting materials.
Abstract:
A light emitting diode device comprises a copper substrate having multiple light emitting regions, multiple dies and encapsulation. Each light emitting region has a die pad and at least one electrode connected together and encapsulant covering the light emitting region. The dies are respectively mounted on the die pads and are wire bonded to the corresponding electrode or electrodes. A step defining a gap is applied to the substrate to form multiple light emitting regions, and each light emitting region has a die pad and electrodes. Therefore, the present invention can simplify the steps for fabricating die pad and electrodes to increase the production rate of LED devices or LED display modules.

Abstract:
An electrode E is manufactured through a series of steps that lend themselves to implementation on a machine tool. Electrode components 100, 158, 190 are joined or welded to other electrode components 62, 100, 158 and then cut to length from a continuous supply of material. Windings of a coil 170 with a relatively narrow inner diameter 174 are opened in a rotating step so that the coil can tightly engage a component 158 having a larger outer diameter 178.
Abstract:
A forming method of spacers in a flat panel display is provided. The method includes the steps of preparing a plurality of spacers in a predetermined shape, preparing a substrate on which the spacers are to be attached in the flat panel display, applying a photosensitive adhesive material on an upper surface of the substrate to a predetermined thickness, aligning the spacers on the substrate to attach the spacers by using the photosensitive adhesive material, radiating light onto the substrate from above the substrate to expose portions of the photosensitive adhesive material without the spacers, and removing the exposed portions of the photosensitive adhesive material. Therefore, the spacers are fixed on the substrate by the photosensitive adhesive material located under the spacers. According to the provided method of forming spacers, the spacers are fixed on the substrate by a mounting process using a jig, a temporary exposing process, and a developing process. In this case, the spacers are simultaneously placed on the substrate by the jig so that the spacers can be precisely aligned. The characteristic of the provided method of forming spacers is very effective in mass production of flat panel displays.
Abstract:
A method for fabricating a flat, light-emitting display panel includes the steps of applying frit seal to the pin electrodes in a state of pressing the rear panel against the front panel to keep them in contact with one another using a flat plate having an opening formed at a position corresponding to each of the pin electrodes; drying the frit seal to fix provisionally the rear panel to the front panel; detaching the flat plate from the both panels; applying frit seal to an end of the front panel and a side face of the rear panel; and burning the whole of components. The sequence of the application of the frit seal to the pin electrode and the application of the frit seal to the end of the front panel and the side face of the rear panel may be altered. The frit seal having flowability less than the frit seal applied to the pin electrode is applied to the end of the front panel and the side face of the rear panel.
