  • Patent number: 7619243
    Abstract: A method of fabricating a color organic electroluminescent display involves forming cathode electrodes on a substrate, and forming a first organic semiconductor layer having an electron-injection transporting property on the cathode electrodes. Solutions containing organic light-emitting material that can dissolve portions of the first organic semiconductor layer are patterned on the first organic semiconductor layer. Then, a solvent in the solutions is removed to form regions having second organic semiconductor layers and mixed organic semiconductor layers, wherein the second organic semiconductor layers are formed on the first organic semiconductor layer and are mostly composed of the organic light-emitting material, and the mixed organic semiconductor layers, composed of the organic light-emitting material and material constituting the first organic semiconductor layer, are embedded in the first organic semiconductor layer. Anode electrodes are formed over the first and second organic semiconductor layers.

  • Patent number: 7560314
    Abstract: A method of fabricating an active array color filter structure utilizes the difference between the surface properties of lipophilicity and lipophobicity. When inks are coated on an active array substrate, ink at the lipophobic areas on the active array substrate will be repelled naturally, 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, because the pixel electrode can extend to cover over the corresponding switch element, aggravation of the switch element is reduced.

  • Publication number: 20070151845
    Abstract: An apparatus for metal plating on a substrate with through-holes includes a chamber that the substrate is disposed inside the chamber to be divided into two sections. A pressure generator and a pressure controller are connected to this and correspond to two sides of the substrate respectively. The pressure generator is used for pumping a electrolyte flowed parallel to the surface of the substrate into the chamber. The pressure controller is used for channeling the electrolyte off the chamber and controlling the pressure differences between the two sides of the substrate. So that the electrolyte flowed parallel to the surface of the substrate is pumped by the pressure generator and it passes several through-holes to control the thickness of metal plating on the.substrate and inner walls of the through-holes.

  • Patent number: 7071662
    Abstract: In prior arts, additional pulse-width modulators and more costs are needed for increasing the current output. The invention provides a synchronized parallel running power converter. The power converter includes multiple power converters controlled by single-phase or double-phase pulse-width modulators. Each power converter includes a first pulse input port, a second pulse input port and a current output port. Each first pulse input ports are coupled, and each second pulse input ports are coupled also, so that each power converter is controlled by the same pulse signal and provide a same output current to be added as several times of current output.

  • Publication number: 20050140706
    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.
