Problems solved by technology

When the position of the inkjet head deviates, the ink ejected from the inkjet head falls outside the pixel pits, and the ink material in each pixel pit on the glass substrate is uneven, which affects the uniformity of the film thickness of the material film, thereby affecting the OLED. Device quality
[0004] Therefore, there are problems affecting the quality of OLED devices in the current OLED device manufacturing process.

Abstract

The invention relates to a warning method and device for ink-jet printing, computer equipment and a storage medium. The warning method for ink-jet printing comprises the following steps: obtaining a plurality of ink-jet head images for an ink-jet head; determining a location identifier image among the multiple ink-jet head images; obtaining an identifier position which corresponds to the locationidentifier image; and generating warning information according to the identifier position, wherein the warning information is used for prompting that the position of the ink-jet head needs to be regulated. According to the warning method and device for ink-jet printing, the problem that the film thickness uniformity of a material film is affected as the position of the ink-jet head deviates, so that quality of an OLED apparatus is improved.

Description

technical field [0001] The present application relates to the technical field of inkjet printing, in particular to an alarm method for inkjet printing, an alarm device, computer equipment and a storage medium. Background technique [0002] With the development of OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) device manufacturing technology, a manufacturing technology based on inkjet printing appears. More specifically, during the manufacture of OLED devices, ink is injected into the pixel pits of the glass substrate through the inkjet head of the inkjet printing equipment to form a layer of material film on the OLED device. [0003] During long-term inkjet printing, the position of the inkjet head may shift. When the position of the inkjet head deviates, the ink ejected from the inkjet head falls outside the pixel pits, and the ink material in each pixel pit on the glass substrate is uneven, which affects the uniformity of the film thickness of the mater...
