Description
Technical field
The invention belongs to display technology field, particularly relate to the manufacture device of a kind of electric wet-type display, the manufacture method of electric wet-type display and electric wet-type display.
Background technology
Electricity is moistening, has another name called electrowetting, and English name is electro-wetting.nullRefer to Fig. 1 to Fig. 4，Electric wet-type display part includes the upper substrate 1 ' and the infrabasal plate 2 ' that are oppositely arranged，Described upper substrate 1 ' includes and infrabasal plate 2 ' is oppositely arranged upper conductive plate 11 ' and the packaging adhesive frame 12 ' being arranged between conductive plate 11 ' and infrabasal plate 2 '，Described infrabasal plate 2 ' includes the lower conducting plate 21 ' being oppositely arranged with upper substrate 1 '、It is arranged at described lower conducting plate 21 ' surface and is positioned at the water-repellent layer 22 ' between described lower conducting plate 21 ' and upper conductive plate 11 ' and is arranged at described water-repellent layer 22 ' surface and is positioned at the pixel wall 23 ' between described water-repellent layer 22 ' and described upper substrate 1 '，Wherein，Described lower conducting plate 21 ' is ITO electro-conductive glass or TFT electrically-conductive backing plate，Described water-repellent layer 22 ' is generally made up of fluorinated polymer，Additionally，Insulating barrier can also be set between lower conducting plate 21 ' and water-repellent layer 22 '，The pattern of pixel wall 23 ' defines the pixel of display device，Region between pixel wall 23 ' is viewing area 24 '，Ink 3 ' and 4 ' two kinds of immiscible fluids of electrolyte solution it are filled with in pixel wall 23 '，Display effect is produced by the motion of two kinds of fluids.Such as RobertA.Hayes etc. are at the display device described in article, and in time not executing alive, ink spreading, on the surface of water-repellent layer, shows the color of ink.Upon application of a voltage, ink shrinks, the color of display infrabasal plate.
Particularity due to electric wet-type display structure, current existing fill method is mainly by the water-repellent layer with hydrophobicity performance being coated in pixel wall bottom surface, ink and electrolyte solution do not dissolve each other, when the ink in electrolyte solution and water-repellent layer contact, ink can spread over water-repellent layer surface, is covered by electrolyte solution above ink simultaneously.Common mode mainly has following several:
(document number is the patent of invention of Liquavista company: WO2009/065909A1) discloses a kind of separatory fill method and has the equipment of liquid separation structure, equipment is made up of hard pmma material, length is determined according to display floater length, width is generally 2 millimeters, the wide 0.1-0.2 millimeter of liquor separator mouth.Middle fluted, groove connects ink injection device.During filling, liquor separator is near subsurface substrate, and during distance 1 micron, injection ink forms oil droplet at its groove, and oil droplet, in substrate process, is filled in pixel, reaches to fill uniform purpose by the back and forth movement of liquor separator.The optimal movement speed of liquor separator is 1 μm/s.Due to the shortcoming of equipment self, limiting the method and be only used for small-area display part, and filling speed is slow, difficulty or ease are produced in batches.
Disclosed in certain paper, a kind of vertical immersion fills method for packing, the method is mainly through adding electrolyte solution and ink in a reservoir, owing to ink density is less than electrolyte solution density, ink can swim in electrolyte solution surface and form one layer of oil film, and the ink adding q.s makes the thickness of oil film reach the thickness more than several pixels.Vertically the substrate being fixed on dip coater is immersed in container with certain with speed, owing to ink spreads in pixel compartments prior to electrolyte solution contacts to fluororesin layer, it is isolated through the ink in the pixel of oil film and comes because of the hydrophilic of pixel wall and covered by electrolyte solution.The ink that the method is fixing because of to form a layer thickness in a reservoir, therefore relatively big and quantity of ink the control of the demand of ink needs very accurate, simultaneously because the volatility of printing ink solvent, it does not have the concentration of way guarantee ink concordance in the filling process.
The patent of invention (document number is US2012/0127555A1) of Liquavista company discloses a kind of method manufacturing optical display, wherein the fill method of disclosed display is similar to vertical immersion, be also one equipped with the container of electrolyte solution in carry out.The difference is that, the method electrolyte surface need not form one layer of ink layer again, but is expelled to by ink in the groove that three phase boundary line place electrolyte surface is formed, and is filled with by the uphill process of electrolysis liquid surface.When the fluoride coating of ink contact to hydrophobic, can automatically be filled in pixel, block continuous print ink and prevent ink residue in pixel wall.Although the method as the vertical substantial amounts of ink of immersion completion method, but need not need also exist for being accurately controlled the amount of ink, otherwise the ink of display device zones of different can be caused to fill inhomogeneities because of the difference of quantity of ink in filling.
The fill method of above-mentioned common electric wet-type display part all requires to carry out in electrolyte solution, and manufacturing process is more complicated.And these existing electric wet-type display parts mainly face problems with when filling: filling speed is slow, lack of homogeneity, waste ink are many, fill requirement is filled with in electrolyte solution environment, operating difficulties is unfavorable for a large amount of production.
