Abstract: A color backlight device and fabrication method thereof is provided. A surface conduction emitter display with more than one color serves as the color backlight device. The color backlight device can be used in a liquid crystal display (LCD) to obviate the use of a color filter. The invention also provides a color display control method of the LCD and a pixel arrangement method of the color backlight device.

Abstract: An apparatus for roll-to-roll processing includes a first roller for converting the transmission of a roll of flexible material from a first direction to a second direction substantially orthogonal to the first direction, a second roller spaced apart from the first roller and extending transversely with respect to the first roller for converting the transmission of the roll of flexible material from the second direction to a third direction substantially orthogonal to the first direction and the second direction, and a third roller spaced apart from the second roller and extending perpendicularly with respect to the first roller for converting the transmission of the roll of flexible material from the third direction to a fourth direction, wherein the roll of flexible material includes a first side and a second side, and wherein the first roller, the second roller and the third roller contact the same one of the first side and the second side of the roll of flexible material.

Abstract: An active array color filter structure and a fabricating method therefor are provided, wherein the difference between the surface properties of lipophilicity and lipophobicity is utilized. When inks are coated on the active array substrate, ink at the lipophobic areas on the active array substrate will be naturally repelled, so that the color filter pixels formed on the active array substrate naturally have contact vias, which facilitates the electrical coupling of pixel electrodes and switch elements. Since there is no aligning or laminating process required for the color filter substrate and the active array substrate during fabrication, no aligning errors will occur. Also, as the pixel electrode can extend to cover above the corresponding switch element, the aggravation of the switch element is reduced.

Abstract: A cleaning device is mounted on either of the sides of an ink-jet printer. The cleaning device uses the power source of a paper delivering motor to transmit power to the cleaning units so that the cleaning units rotate to perform cleaning and scrubbing operations for an ink-jet print head. When the printer performs printing operations, the paper delivering motor is used to deliver paper without causing an interference with the ink-jet print head during the printing operation. When the ink-jet print head needs to be cleaned, an ink carriage moves to be opposed to the cleaning device under the ink carriage, then, the paper delivering motor supplies power to drive an external transmission device set. The external transmission device set drives the cleaning device on the revolving seat to rotate so as to clean the ink-jet print head of the ink carriage.

Abstract: A method for patching element defects by ink-jet printing includes steps of identifying all defects of the element by image analysis and obtaining an optimal ink-jet printing path of the ink-jet head. The ink-jet head repairs all defects of the element with the shortest distance along the optimal patching path. Moreover, the ink-jet head repairs all defects of the element in a stable manner so as to increase the yield rate.

Abstract: A method for forming metal wires by microdispensing a pattern is disclosed. The method includes the steps of microdispensing a catalyst pattern on the substrate and forming metal wires by electroless plating. Before the step of microdispensing catalyst pattern, the surface properties of the substrate have been improved by a surface modification treatment.

Abstract: A thin film-forming method and apparatus for forming flat films on a substrate utilizes micro-dispensing inkjet printing. Physical vibration is induced on the substrate to destroy the surface tension of droplets adhering on the substrate. The physical force influence the surface tension and holds the solute in position and prevent them moving by capillary force to the rim of droplet and accumulating there so as to get a flat thin film during the volatilization of the droplet. The vibration also regulates the droplet shape into nearly true round.

Abstract: A disc clamping device with self lock elements particularly for DVD-ROM or CD-ROM fixedly maintained on a turntable when disc is rotating in high speed. The device comprises a turntable having a boss on the center for putting disc thereon, and a disc clamping member tightly sleeved on boss having protuberances on periphery wherein protuberances are deformed inwards when biased by disc such that disc can insert through disc clamping member, and then protuberances return to original forms by elastically energized force for clamping disc on turntable. By utilizing this, the purposes of decreasing the umber of parts, easy assembly, and high precision positioning of disc are achieved.

Abstract: A disc clamp mechanism for preventing a disc (e.g., DVD-ROM or CD-ROM) from slipping and/or loosening in a high speed rotation comprises a positioning member sized to the center hole of the disc having a hole for being mounted on a turntable, and an inclined surface; a helical spring within the positioning member; a disc-clamping member sized to the center hole of the compact disc having circumferential raised portions, recessed portions each extending from the raised portion, and flexible V-shaped members surrounded by two recessed portions and a raised portion; and an elastic plane-like member mounted on the positioning member. As such, the disc is secured by the raised portions, the inclined surface, and the turntable when loaded onto the disc-clamping member. This mechanism finds applications in the DVD-ROM or CD-ROM products. Further, a thinner construction, an easy assembly, and a high positioning precision are realized by this mechanism.
