Compared with conventional cathode ray display device, liquid crystal display (LCD) uses visible ray light source as a setting, does not produce harmful radiation when use, has environmental protection, the many advantages such as energy-conservation.Therefore along with the development of information technology, LCD has been widely used in various application occasions.For example for the small-scale liquid crystal display screen of mobile communication equipment, human-computer dialogue liquid crystal instrument dish of automatically producing for the LCDs of notebook computer, for the liquid crystal display dish of automobile instrument panel, for the LCD TV of family expenses, for industrialization etc.Along with the large-scale application of the suitability for industrialized production of thin film transistor (TFT) (TFT), liquid crystal display is to high-resolution, large scale and ultrathin future development, its research is quite active, and the every aspect that liquid crystal display is produced is studied quite fully.
At present, the primary structure of TFT-LCD comprises box array base palte and color membrane substrates (CF) together, and wherein color membrane substrates mainly comprises glass substrate, black matrix (Black Matrix is called for short BM), chromatic photoresist and diaphragm.Generally speaking, the Main Function of chromatic photoresist is to utilize the mode filtering to produce red green blue tricolor, then red green blue tricolor is mixed with different strong and weak ratios, thereby presents various colors, TFT-LCD is demonstrated full-color.
The preparation method check and correction of chromatic photoresist, but consider economic benefit, make the functional requirement of stability and chromatic photoresist, as color saturation, resolution ratio etc., conventional chromatic photoresist preparation method comprises decoration method, Pigments method, print process and electric colouring.Wherein, Pigments method is because the advantages such as the high color purity of its made chromatic photoresist, high accuracy, miniaturization become the preparation method of topmost chromatic photoresist.The general principle of Pigments method is that colored photoresist is coated on transparent underlay substrate, then adopts the similar light such as ultraviolet ray to irradiate, and makes colored photoetching adhesive curing form chromatic photoresist.The critical process of the colorful visualization of LCD just colored photoresist on substrate, adhere to processing, and the quality of colored photoresist directly affects the color developing of LCD.
Those skilled in the art know, thereby LCD regulates the transmitance of polarised light to realize corresponding color display effect by the orientation of electric field controls liquid crystal molecule.Pigment liquid is the important component part of colored photoresist, has determined the chroma characteristic of colored photoresist.In the case, the decentralization of pigment liquid is had relatively high expectations, and whether what pigment liquid disperseed in colored photoresist evenly can affect great on colored photoetching colloidality.In prior art, in the process of the colored photoresist of preparation, add the device of pigment liquid as shown in Figure 1.Adopt this kind of device, add the interior pigment liquid of material container (2) and can reinforced passage (21) exit region in agitating device (1) form concentrating to a certain degree, time that need to be longer by its uniform dispersion, dispersion efficiency is not high.
Therefore, need innovation ground to propose a kind of dispersed with stirring device, make it improve the dispersion efficiency of pigment liquid, to reach the requirement of LCD manufacturing technology to effective Pigments stablizing effect, thereby meet the needs of practical application.
Utility model content
Outside the deficiencies in the prior art, the purpose of this utility model is to provide a kind of dispersed with stirring device, makes it improve Pigments efficiency.
In order to address the above problem, the utility model provides a kind of dispersed with stirring device, and wherein, shaft is hollow, and one end and reinforced channel connection, and the other end is communicated with stirring-head, on described stirring-head, discharging opening is set.The utility model on the basis of existing technology, creatively change the addition manner of pigment liquid, take the mode that the reinforced passage of pigment liquid is communicated with the shaft of hollow, make the discharging opening of pigment liquid from stirring-head enter colored photoresist, and the centrifugal force producing while being rotated by stirring-head is scattered in pigment liquid rapidly in colored photoresist, greatly improve the dispersion efficiency of pigment liquid in colored photoresist, greatly shortened the man-hour of this operation.
Preferably, described stirring-head is oar blade type stirring-head.Oar blade type stirring-head is conducive to pigment liquid and more effectively disperses in colored photoresist.
Preferably, described oar blade type stirring-head at least arranges two blades.Two above blades are conducive to pigment liquid and under the rotation of stirring-head, disperse more rapidly from discharging opening enters colored photoresist.
Preferably, each described blade is hollow blade, and is communicated with described shaft, and a side of each described hollow blade is described discharging opening.A side that discharging opening is arranged on to hollow blade contributes to pigment liquid to flow into colored photoresist from the shaft of hollow, and is conducive to rapid dispersion.
Preferably, the opening direction of described discharging opening is the tangential direction of blade operation, and the mixing direction of blade is sealing, and rightabout is opening; Further preferred, the whole openings of the thinner side of blade are discharging opening.The tangential direction that discharging opening is arranged to blade operation is conducive to pigment liquid under the effect of the centrifugal force of stirring-head rotation generation, flows into fast colourama and carves in glue.In the time that the thinner whole openings of a side of blade are discharging opening, the dispersion of pigment liquid is more rapid effectively.
It will be understood by those skilled in the art that, adopt dispersed with stirring device of the present utility model, pigment liquid enters dispersed with stirring device along reinforced passage from adding material container of storing pigment liquid under the effect of pump, pigment liquid pump enters the hollow pipeline of shaft, and the colored photoresist flowing in dispersed with stirring device by the discharging opening being arranged on stirring-head is dispersed.Along with the continuous stirring of stirring-head, the pigment liquid entering is dispersed in colored photoresist continuously, the concentrating to a certain extent that can't occur that pigment liquid forms in reinforced channel outlet region, the situation of the long-time dispersed with stirring of needs.
In addition, the rightabout that the opening of discharging opening is arranged to the mixing direction of stirring-head is conducive to pigment liquid along the direction contrary with mixing direction, under the whipping effect of the centrifugal force producing in stirring-head rotation, enter in the colored photoresist in dispersed with stirring device, contribute to pigment liquid to enter fast in colored photoresist to be disperseed.
The beneficial effects of the utility model:
Dispersed with stirring device of the present utility model is by changing the addition manner of pigment liquid, the technological means that feed in raw material passage and shaft are combined, centrifugal force while simultaneously rotation by stirring-head is scattered in pigment liquid rapidly in colored photoresist, has improved the dispersion efficiency of pigment liquid in colored photoresist.
