Abstract

The invention relates to an ink jetting printing head correction method, apparatus and system, a computer apparatus and a storage medium. The method comprises the steps of controlling nozzles of an ink jetting printing head to drop ink droplets on a test substrate; detecting and obtaining the number of the ink droplets dripping on the test substrate, and determining the actual using number of thenozzles on the ink jetting printing head according to the number of the ink droplets; determining whether the actual using number of the nozzles is the same as the target using number of the nozzles or not; and if the actual using number of the nozzles is not the same as the target using number of the nozzles, correcting the current actual using number of the nozzles of the ink jetting printing head to be the same as the target using number. The above method ensures that the actual using number of the nozzles of the ink jetting printing head is the same as the target using number, the problemthat the current actual using number of the nozzles of the ink jetting printing head is not the same as the target using number due to person operation negligence, and consequently a device for ink jetting printing preparation is abnormal is solved, and the accuracy of the using number of the nozzles in ink jetting printing is improved.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to an inkjet printing head calibration method, device, system, computer equipment and storage medium. Background technique [0002] Inkjet printing technology has been widely used in the device manufacturing process in addition to the printing of traditional paper text patterns. For example, some functional materials in the OLED device manufacturing process can use inkjet printing technology, such as the hole injection layer ( HIL), hole transport layer (HTL), light emitting layer material (EML), etc. That is, in the known pixel pits, the functional layer material ink is injected into the pixel pits by inkjet printing, please refer to figure 1 shown. [0003] When performing inkjet printing, it is generally required that all nozzles that meet the ink droplet parameters participate in the inkjet printing process, but in some cases, before the inkjet printing process, the in...
