Description of the embodiments
In order to better understand the technical solutions of the present disclosure, an inkjet printing apparatus and an inkjet printing method provided by the present disclosure are described in detail below with reference to the accompanying drawings.
In the related art, since the number of heads in the inkjet printing apparatus is limited, printing of the entire substrate cannot be completed by one printing, and thus it is necessary to perform division printing on the substrate, which has a problem that: because of the difference between the ink drop concentration and the drying atmosphere of each printing area on the substrate, the volatilization speed of the solvent is different when the ink drops are dried, the volatilization speed of the first printing area is faster than that of the later printing area, and the volatilization speed of the printing edge area is faster than that of the inner area, so that the film thicknesses of different printing areas of the substrate are uneven, and printing defects are formed.
In order to solve the technical problems, the technical scheme of the present disclosure provides a corresponding solution.

In the embodiment of the present disclosure, the temperature of the substrate 3 to be processed may be set by the temperature control structure 101 before performing the inkjet print job, according to factors such as physical properties, chemical properties, dry film forming properties, and the like of the ink. The main component of the printing ink material is a solvent, the saturated vapor pressures of the solvent at different temperatures are different, and the saturated vapor pressures directly influence the volatilization rate of the solvent. The boiling point, saturated vapor pressure and volatility of the solvents of different ink materials are different, so that before the ink-jet printing operation, the proper temperature of the substrate 3 to be treated can be set according to the physical, chemical and drying film-forming characteristics of the ink, the volatilization rate of the solvents of the ink is regulated and controlled, the printing process is optimized, and the uniformity of drying film-forming of the printing ink is improved.
For an ink system capable of being dried quickly and formed into a film uniformly, the temperature of the substrate 3 to be processed is raised through the temperature control structure 101, printing and drying are realized, a subsequent drying process is omitted, and printing efficiency is improved; for an ink system which is uniformly formed into a film through a slow and proper vacuum degree drying process, the temperature of the substrate 3 to be processed is reduced through the temperature control structure 101, so that the volatilization rate of ink drop solvents on the substrate 3 to be processed is reduced, the uniformity of ink drops in each pixel pit on the whole substrate 3 to be processed is maintained, the next drying process is carried out after printing is finished, and the uniformity of film thickness after drying can be ensured.

In some embodiments, the heat exchange fluid comprises: water or ethanol. Water and ethanol are common fluids and are relatively low cost. In addition, the specific heat capacity of water and ethanol is relatively small, so that the temperature change speed is high, and the rapid temperature adjustment of the temperature control structure 101 is facilitated.

For an ink system capable of being dried rapidly and formed into a film uniformly, the temperature of a substrate to be processed is increased through a temperature control structure, printing and drying are realized, a subsequent drying process is omitted, and printing efficiency is improved; for an ink system which is uniformly formed into a film through a slow and proper vacuum degree drying process, the temperature of a substrate to be processed is reduced through a temperature control structure, so that the volatilization rate of ink drops on the substrate to be processed is reduced, the uniformity of the ink drops in each pixel pit on the whole substrate to be processed is maintained, the next drying process is carried out after printing is finished, and the uniformity of film thickness after drying can be ensured. The technical scheme of the disclosure can effectively improve the overall film forming uniformity of the ink in the printing pixel pits of the whole substrate, reduce printing defects and further improve the performance of the final product.
Fig. 6 is a schematic diagram of ink in pixel pits in different areas on a substrate to be processed at the end of an inkjet printing process in the related art, as shown in fig. 6, taking printing alcohol ink as an example, part (a) in fig. 6 is a case of ink 4 in pixel pits in a first printing partition on the substrate to be processed at the end of the inkjet printing process, and part (b) in fig. 6 is a case of ink 4 in pixel pits in a last printing partition on the substrate to be processed at the end of the inkjet printing process. As can be seen from fig. 6, the ink 4 in the pixel pit in the first printing partition is seriously volatilized, the ink 4 in the pixel pit in the last printing partition is kept full, and the ink 4 in the pixel pit in different printing partitions is inconsistent; after drying treatment, the appearance of the thin film obtained in the pixel pits in different printing areas is inconsistent. In addition, the film thickness of the thin film in the pixel pits in the printing partition where the ink-jet printing is finished is also uneven, and the appearance of thin middle and thick edge is generally presented.

As can be seen from fig. 7, since the substrate to be processed is subjected to the temperature lowering treatment so that the ink 4 in the pixel pit in the first printing partition is substantially non-volatile, the ink 4 in the pixel pit is kept full; meanwhile, the ink 4 in the pixel pit in the last printing partition is kept in a full state, and the states of the ink 4 in the pixel pits in different printing partitions are consistent; after drying treatment, the appearance of the thin film obtained in the pixel pits in different printing areas is consistent.
