Abstract:
A color filter includes a transparent substrate, a black matrix formed on the transparent substrate, a plurality of banks superposed on the black matrix, and a color layer formed of R, G and B color portions. The black matrix defines a plurality of sub-pixels of the color filter. The banks and the black matrix enclose a plurality of spaces for respectively accommodating the R, G and B color portions. Wherein, a plurality of groups is defined, each group includes a plurality of sub-pixels of concolorous color portions, at least one channel is formed on the bank between adjacent sub-pixels of concolorous color portions in the group. In a manufacturing method for the color filter, the ink can flow over between the adjacent sub-pixels in a defined group and level through the channel, thus the uniformity of the color portions can be improved.

This invention relates to a control method and structure of electrode device of a direct electrostatic printing apparatus which enables multi-leveled print depth on recording medium. By utilizing the electrode device with multiple electrode layers having at least an aperture passing through and corresponding to every print dot, as different level of print depth is needed, different voltage value is applied to the electrode device, thereby establishing a different magnitude of electric field and driving varied amounts of charged colorants passing through the aperture on the electrode device from the cartridge device and being attached onto the recording medium.

Abstract:
A substrate structure includes a substrate and a number of banks formed on the substrate. The banks and the substrate cooperatively define a number of accommodating rooms. The accommodating rooms are configured for accommodating ink. A spread-control layer is formed on the substrate beneath the accommodating rooms. The spread-control layer enables the ink applied on the spread-control layer to spread at a lower spreading rate than the rate on the substrate without the spread-control layer formed thereon.
Abstract:
An ink composition includes a colorant, a solvent, and at least one component selected from the group consisting of monomer, oligomer, and macromolecule resin. The vapor pressure of the solvent is smaller than 0.33 mmHg at 20° C., but when the temperature of the solvent is between 60° C. and 90° C., the vapor pressure thereof increases at least five times than that of the solvent at 20° C. and/or the evaporation rate is larger than one tenth of that of butyl acetate at 20° C. The ink composition has excellent practicability. A manufacturing method of color filter using the ink composition includes the steps of: providing a transparent substrate; forming a black matrix on the transparent substrate; forming a plurality of banks on the black matrix; ejecting the ink composition into spaces defined by the banks via an ink jet device; and solidifying the ink composition.

Abstract:
The invention discloses a manufacturing processing of making a flexible printed circuit for inkjet printheads. Through the change of the flexible printed circuit structure, residual stress at the bent part can be reduced and the efficiency and precision of subsequent processes can be increased. The disclosed process is thus able to make products with high reliability and quality. The process involves the steps of: (1) preparing a flexible printed circuit substrate and making a window at a predetermined bent part; (2) coating the substrate with a metal layer so that the substrate become conductive; (3) etching the metal layer through a photolithography process to produce a conductive circuit on the flexible printed circuit; and (4) forming a cover layer (solder mask materials such as epoxy or acrylic resins) at the window. A flexible printed circuit thus produced is pre-bent, easy to attach and align, and has less residual stress and a cover layer or film at the bent part.
