Abstract

The invention discloses an ink-jet printing method, a printing substrate and an ink-jet printing device.The ink-jet printing method comprises the steps that before formal printing, a nozzle in a spray head is controlled to conduct ink-jet printing on an opening area of a first pixel in a pre-printing area at a preset printing ink volume so as to obtain a pre-printing pattern; the first pixels in the pre-printing area and the second pixels on the printing substrate are correspondingly arranged and are the same in size; and after printing, the ink volume of the first pixel is calculated according to the collected pre-printing pattern, the preset printing ink volume of the nozzle is finely adjusted according to the ink volume of the first pixel, and the nozzle is controlled to perform ink-jet printing on the opening area of the second pixel on the printing substrate according to the target printing ink volume. Therefore, the influence of crosstalk in the printing process can be eliminated, and the volume uniformity of ink-jet printing ink among pixels can be improved.

Description

technical field [0001] The invention relates to the field of display technology, and in particular, to an inkjet printing method, a printing substrate and an inkjet printing device. Background technique [0002] In the current inkjet printing equipment, there is a piezoelectric ceramic material in the printing nozzle. When a voltage is applied to the piezoelectric ceramic material, the piezoelectric ceramic material will deform, and the microcavity where the nozzle is located will produce a pressure change, and the ink will be squeezed out. However, based on the fluidity characteristics of the fluid, the currently active nozzle will have a crosstalk effect on the adjacent nozzles, resulting in the difference between the ink discharge volume of the adjacent nozzles and the independent discharge volume, and in the actual printing process, the calling timing of different nozzles Different crosstalk will affect the results, resulting in differences in ink volume between pixels, ...
