  • Publication number: 20070290068
    Abstract: A micro-pump used for atomizing liquid is provided. The micro-pump includes a main-housing, a nozzle plate, and at least one actuator. The main-housing has a liquid inlet. The nozzle plate is assembled to the main-housing and has at least one nozzle. A first chamber is formed between the main-housing and the nozzle plate, and the nozzle and the liquid inlet are communicated with the first chamber. The actuator is disposed on the main-housing and/or the nozzle plate. The actuator drives the nozzle plate, so that liquid is filled into the first chamber and sprayed out through the nozzle. A micro-pump system can be formed by many micro-pumps.

  • Publication number: 20070158477
    Abstract: A spraying device for atomizing a liquid is proposed. The spraying device includes a nozzle plate and an actuator. The nozzle plate is provided with a plurality of nozzle apertures. Each of the nozzle apertures includes an entry end for the liquid to enter and an exit end for the liquid to exit. The entry end and the exit end of at least one of the nozzle apertures are asymmetrical structures. The actuator is integrated with the nozzle plate to actuate atomization of the liquid. The spraying direction of a liquid droplet after the liquid is atomized can be controlled by modifying the shape of the exit end of the nozzle aperture.

  • Publication number: 20070120898
    Abstract: A droplet ejecting head includes a first substrate, a nozzle plate, a second substrate, an annular symmetrically channel plate and an actuator device. The nozzle plate with a nozzle is disposed on a first surface of the first substrate. The second substrate with a liquid inlet is disposed over the first substrate. The annular symmetrically channel plate with a fluid channel is disposed between the first substrate and the second substrate so that a pressure chamber is formed between the second substrate and the annular symmetrically channel plate. The liquid to be ejected flows to the fluid channel from the liquid inlet and overflows to the pressure chamber from the fluid channel. The actuator device is disposed on the second substrate. The second substrate is deformed by the actuator device for changing volume of the pressure chamber, and then the liquid in the pressure chamber is ejected via the nozzle.

  • Publication number: 20070040870
    Abstract: A nozzle plate suited for a droplet generator is provided. The nozzle plate includes a nozzle layer and at least one filler. The nozzle layer has a nozzle and at least one trench. The nozzle passes through the nozzle layer. The trenches apart from the nozzle are formed on a surface of the nozzle layer around the nozzle. The filler is filled in the trench. The wetting angle of the surface of the filler is different from the wetting angle of the surface of the nozzle layer. The nozzle plate has higher surface wear resistance and lower probability of jamming at the nozzle.

  • Patent number: 7108360
    Abstract: A structure of the stacked inkjet head is composed of a stacked fluid structure and an actuator. At least one of the several plates in the stacked fluid structure has a junction with a tuning hole for enhancing the connection strength of the junction, accommodating overflown adhesive, and reducing structural deformation resulted from the temperature. The invention also avoids the troubles of inhomogeneous etching speeds when making nozzles or channels.

  • Publication number: 20050074546
    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.

  • Patent number: 6844120
    Abstract: A micro-fluidic manufacturing method of forming a color filter. First, a transparent substrate is provided with a plurality of black matrixes. Then, a plurality of ribs are formed on the black matrixes respectively, wherein the width of the rib is not larger than the width of the black matrix. Next, a plurality of micro fluids is injected within a plurality of predetermined areas separated by the ribs, wherein the micro fluids within each predetermined area are mixed to serve as an ink. Next, each ink within each predetermined area is dried to form a plurality of color layers of different colors. Finally, after removing the ribs, a transparent conductive layer is formed on the transparent substrate to cover the black matrixes and the color layers.

  • Patent number: 6703173
    Abstract: A color filter for liquid crystal display panels. The filter includes a transparent substrate with a metal layer formed thereon, and a first color layer, a second colour layer and a third color layer are integrally formed with the same metal layer. The invention also provides a method for producing the color filter described above. The method applies the theory of oxidizing metal layers by repeatedly exposing and oxidizing to form a color filter having multiple integrally formed colors. Depending on requirements, the color filter of the invention also includes the black matrix that is often included in liquid crystal display panels.
