Detailed description of the invention

Below in conjunction with accompanying drawing the present invention done and further explain.

Improve a method for printing precision by surperficial imbibition characteristic, in the present embodiment, the method is used for typographical display field.First, prepare easy wetted area and non-infiltration regional graphics according to printing information at substrate surface, the wellability difference in two regions is mainly reflected in the contact angle size of printing ink in these two regions; In tradition, the contact angle of material surface is less than 90 ° for having easy imbibition characteristic, and the contact angle of material surface is greater than 90 ° for having non-infiltration characteristic.Due to the difference of contact angle, printing ink is easy to contact with easy wetted area, and extremely low in non-infiltration region adhesion.Region outside pixel cell, for a certain pixel cell, is prepared into non-infiltration region, and pixel cell is prepared into wetted area by the present embodiment.When individual layer printing only need be carried out, in order to realize the automatic correction of spraying dot placement error in electronic printing, the contact angle difference of non-infiltration region and easy wetted area meets the scope of 30 °-170 °, its contact angle difference is larger, wellability difference is more remarkable, and the effect of automatically correcting is better.

Carry out electronic printing step in easy wetted area, when spraying ink droplet and contact with easy wetted area with non-infiltration region simultaneously, under surface tension effects, spray ink droplet automatically leave non-infiltration region and cover wetted area, realize the automatic correction of electronic printing error.Automatic correction procedure as shown in Figure 1, 2, printing zone corresponds to easy wetted area 10, its surrounding is non-infiltration region 11, when ink jet printing device sprays ink droplet 12 to this pixel, due to typography equipment error cause spray ink droplet 12 with the substrate contacts initial stage time, spray ink droplet 12 and can be in non-infiltration region 11 and easy wetted area 10 intersection, as shown in Fig. 1 (a).There is infiltration difference in two regions contacted owing to spraying ink droplet 12, spray ink droplet 12 and can automatically leave non-infiltration region 11 and cover wetted area 10 under surface tension effects, film forming of finally volatilizing, as shown in Fig. 1 (b).As shown in Fig. 2 (a), in this enforcement, spray ink droplet 12 and substrate contacts moment, being 110 ° with the contact angle in non-infiltration region 11, is 50 ° with the contact angle of easy wetted area 10, forms asymmetric configuration; Under surface tension effects, spray ink droplet 12 and automatically move away non-infiltration region 11, cover easy wetted area 10, as shown in Fig. 2 (b).

Further, prepare in non-infiltration region 11 in advance rule or irregular micron scale construction or nanoscale structures or micro-nano dual structure, can adopt organic material or inorganic material preparation, its preparation method can be: chemically grown method, laser ablation method, chemical etching method, electrochemical growth method, physical deposition methods and other micro-nano technological method for processing.The dual structure prepared by said method makes non-infiltration region 11 realize superhydrophobic characteristic or super two thin characteristic, namely superhydrophobic characteristic refers to that water-base ink is greater than 150 ° at the contact angle in this region, and namely super two thin characteristic refers to that solvent-based inks and water-base ink infiltrate angle and be all greater than 150 °.When non-infiltration region 11 possesses superhydrophobic characteristic or super two thin characteristic, easy wetted area 10 is applicable to carrying out multilayer electronic printing, for above-mentioned pixel cell, after carrying out ground floor printing, printing ink drying forms smooth film afterwards, when the second layer prints, the contact angle of printing ink on this film is generally less than 90 °.Because printing ink is greater than 150 ° at the contact angle in the non-infiltration region of superhydrophobic characteristic or super two thin characteristic, the film formed at ground floor by printing ink and the contact angle difference in this non-infiltration region, the automatic correction that ink droplet also can complete position is sprayed when making to print the second layer, repeatedly accurately locating when completing multi-sheet printed by that analogy, thus realize the accurate deposition of multilayer luminescent material in pixel.

In this method, by the easy wetted area 10 of design and non-infiltration region 11 at the relative position figure of substrate surface, the corresponding printing information in easy wetted area 10 surface can be realized.Because printing ink only realizes deposition in easy wetted area 10, therefore easily the shape of wetted area 10 just determines last printed pattern.

The above is only the preferred embodiment of the present invention, any printing images realized according to the inventive method, printed electronic device and thus method develop other realize Method and Technology of accurately printing all within the inventive method protection domain by wellability difference.
