OLED pixel layer jet printing drop point position planning and jet printing control method

The invention relates to the technical field of OLED ink-jet printing, and discloses an OLED pixel layer jet printing drop point position planning and jet printing control method. The method comprises the steps of obtaining ink characteristics and printing substrate characteristics; based on ink characteristics and printing substrate characteristics, a printing substrate pixel groove is divided, and divided areas are obtained; printing point locations are generated based on the divided areas; a printing nozzle identifier of the printing point location is determined; and printing according to the printing point position, the printing nozzle identifier of the printing point position and a preset printing direction. According to the whole scheme, the pixel grooves of the printing substrate are divided based on multi-dimensional printing related attributes, the printing point positions are generated based on the divided areas, compared with a traditional printing point position obtained based on the ink droplet v
