20080291228 | METHODS AND APPARATUS FOR INKJET PRINTING WITH MULTIPLE ROWS OF PRINT HEADS - According to the present invention, multiple rows of nozzles within a print head may be arranged proximal to and offset from each other to facilitate inkjet printing. Print heads may comprise a single row of nozzles or may comprise a plurality of rows of nozzles. Each row of nozzles may be situated such that the immediately adjacent row of nozzles may be offset by a predetermined distance. In some embodiments, adjacent rows of nozzles may each print with the same color. In this way, adjacent offset rows of nozzles may be used in combination to dispense ink drops into sub-pixel wells in improved patterns and with improved ink distribution within the sub-pixel well. These offset print techniques may also enable tighter grouping of ink drops within a sub-pixel well and enable faster printing operations. | 11-27-2008 |
20080309715 | METHODS AND APPARATUS FOR DEPOSITING INK ONTO SUBSTRATES - Embodiments of an ink jet printing system include a motion stage adapted to move a substrate having a display object in a printing direction and a first printing assembly mounted over the motion stage including a set of print heads aligned and arranged consecutively in the printing direction such that the display object moves under the print heads sequentially. Embodiments of a method of ink jet printing include moving a substrate under the print heads of printing assembly sequentially in a printing direction, activating alternate ink jetting channels within each print head of the first printing assembly, activating corresponding channels within adjacent print heads in the first printing assembly alternately, and depositing ink in alternating sub-pixels within one or more pixels on the substrate. | 12-18-2008 |
20090141218 | METHODS AND APPARATUS FOR CURING PIXEL MATRIX FILTER MATERIALS - In the formation of color filters for flat panel displays, the invention includes concurrently curing and shrinking a pixel matrix and a color material on a substrate to achieve a substantially co-planar top surface. The invention includes applying a first activation energy to a pixel matrix material to render the material partially cured, minimally shrunk, hardened, and chemically ready for the application of a color material; applying the color material; and concurrently shrinking the color material and pixel material by the application of at least an additional activation energy wherein the additional activation energy is greater than the first activation energy. Numerous other aspects are provided. | 06-04-2009 |
20090184990 | METHODS AND APPARATUS FOR MEASURING DEPOSITED INK IN PIXEL WELLS ON A SUBSTRATE USING A LINE SCAN CAMERA - Systems and methods for measuring deposited ink in a substrate are provided. The invention includes a light source adapted to transmit light through a deposited ink on a substrate, and a camera having a CCD sensor array wherein the camera is adapted to measure the amount of light that is transmitted through the deposited ink. Numerous other aspects are provided. | 07-23-2009 |
20090185186 | SYSTEMS AND METHODS FOR IMPROVING MEASUREMENT OF LIGHT TRANSMITTANCE THROUGH INK DEPOSITED ON A SUBSTRATE - Systems, methods and apparatus for manufacturing color filters for flat panel displays are provided that include an inkjet printing system integrated with a light transmittance measurement system. The inkjet printing system includes a stage for supporting and moving a substrate past inkjet print heads adapted to deposit ink in pixel wells on the substrate. The light transmittance measurement system includes a sensor and a light source disposed on opposite sides of the substrate and adapted to determine the thickness of the ink deposited on the substrate. The light source is adapted to move with the sensor to allow different pixel wells containing deposited ink to be measured, and the stage includes at least one optical path to allow light from the light source to pass through the deposited ink to the sensor. | 07-23-2009 |

20110045170 | IN-SITU DEPOSITION OF BATTERY ACTIVE LITHIUM MATERIALS BY THERMAL SPRAYING - A method and apparatus for forming an electrochemical layer of a thin film battery is provided. A precursor mixture comprising electrochemically active precursor particles dispersed in a carrying medium is provided to a processing chamber and thermally treated using a combustible gas mixture also provided to the chamber. The precursor is converted to nanocrystals by the thermal energy, and the nanocrystals are deposited on a substrate. A second precursor may be blended with the nanocrystals as they deposit on the surface to enhance adhesion and conductivity. | 02-24-2011 |
20110045206 | IN-SITU DEPOSITION OF BATTERY ACTIVE LITHIUM MATERIALS BY PLASMA SPRAYING - A method and apparatus for forming an electrochemical layer of a thin film battery is provided. A precursor mixture comprising precursor particles dispersed in a carrying medium is activated in an activation chamber by application of an electric field to ionize at least a portion of the precursor mixture. The activated precursor mixture is then mixed with a combustible gas mixture to add thermal energy to the precursor particles, converting them to nanocrystals, which deposit on a substrate. A second precursor may be blended with the nanocrystals as they deposit on the surface to enhance adhesion and conductivity. | 02-24-2011 |
20110111181 | METHODS AND APPARATUS FOR BALANCING IMAGE BRIGHTNESS ACROSS A FLAT PANEL DISPLAY USING VARIABLE INK THICKNESS - The present invention provides methods, apparatus and systems for balancing the brightness of a flat panel display using varying thicknesses of ink in a display object. The invention includes a display object for a flat panel display which includes a substrate, a pixel matrix on the substrate, and ink deposited into the pixel matrix. The ink deposited in a central area of the pixel matrix has a thickness that is greater than ink deposited in an edge/corner area of the pixel matrix.
