Problems solved by technology

That is, with the following disadvantages of the gas distributor
[0018] ① Poor stability of coating flow
[0019] ②The end of the continuous line cannot be formed with high quality
As a result, phenomena such as "thinning" or "missing" occur at the starting point of the drawn line

no. 1 Embodiment approach

[0103] figure 1 It is a schematic partial cross-sectional view illustrating a fluid application device for carrying out the fluid application method according to the first embodiment of the present invention.

[0104] 1 is a piston, and 2 is a housing for accommodating the piston 1 . When using a non-conductive coating material, the shell 2 can use any insulating material or conductive material. When the shell 2 uses conductive material as a whole, the front end of the nozzle is closest to the substrate, so the electric field intensity is the largest, which will not affect The function of electric field control. However, when a high voltage is not applied to the entire casing 2 in consideration of safety, if Figure 29 As shown in the specific example, it is also possible to only provide the discharge part of the electrode (in Figure 29 364) uses insulating materials, and other positions use conductive materials. In addition, a conductive material or an insulating materi...

no. 2 Embodiment approach

[0117] figure 2 , Figure 3A and Figure 3B It is a schematic partial cross-sectional view illustrating a fluid application device for implementing a fluid application method according to a second embodiment of the present invention, figure 2 (A), (B), and (C) each show a flow chart from the state of continuous coating to the state of shutoff coating and then to the state of starting coating. The piston shaft of the dispenser used in the fluid application device and method of the second embodiment, such as Figure 10 As shown in the specific example of , it is a structure that can be rotated and linearly moved by a 2-degree-of-freedom driver.

[0118] 101 is a piston, and 102 is a housing for accommodating the piston 101 . The piston 101 is housed in a housing 102 as a fixed side so as to be able to rotate independently and move linearly. When using a non-conductive coating material, the housing 102 can use any insulating material or conductive material. When the whole ...

no. 3 Embodiment approach

[0129] Figure 4A and Figure 4B It is a schematic partial cross-sectional view illustrating a fluid application device capable of implementing the fluid application method according to the third embodiment of the present invention, as the suction force generated to return to the inside of the discharge nozzle: f 2 Another example of the device, showing the use of thrust dynamic pressure seals. The piston shaft of the dispenser used in the fluid application device and method of the third embodiment is the same as the fluid application device and method of the second embodiment, and is driven by a 2-degree-of-freedom driver (specifically, a rotation transmission device) 603A and axial movement device 604A) can simultaneously rotate and linearly move the structure. A thrust dynamic pressure seal is formed between the discharge-side end surface of the piston shaft and its opposing surface.

[0130] 601 is a piston having the same thread groove as that of the piston 101 , and 6...

Abstract

A meniscus of applying fluid is controlled by applying a voltage to a discharge-nozzle side electrode and a counter electrode placed downstream of the discharge nozzle and by increasing or decreasing fluid pressure inside a pump chamber with use of a mechanism for rotational motion or rectilinear motion.

Description

technical field [0001] The present invention relates to a fluid applicator and a fluid applicator with a small flow rate necessary in the fields of information, precision machinery, machine tools, FA (factory automation), etc., or in various production processes such as semiconductors, liquid crystals, displays, and surface mounts. A cloth method, a plasma display panel formed by the fluid coating method, and a pattern forming method thereof. Background technique [0002] Hereinafter, a conventional printing method will be described by taking a method of forming a phosphor layer of a plasma display panel (hereinafter referred to as PDP) as an example. [0003] In a PDP that performs color display, phosphor layers made of phosphor materials that emit light in RGB (red, green, blue) colors are provided on the front panel / rear panel. The phosphor layer is formed in parallel lines between the partition wall and the partition wall (that is, on the address electrode) formed on th...
