Alarm method, inkjet control terminal and inkjet printing equipment

Abstract

The invention relates to an alarm method, an inkjet control terminal and inkjet printing equipment. The alarm method of inkjet printing includes the following steps: obtaining positioning identification of an inkjet substrate; obtaining an actual position corresponding to the positioning identification; and generating alarm information according to distance between the actual position and a set reference position, wherein the alarm information is used for indicating that the position of the inkjet substrate needs to be adjusted. According to the embodiments of the invention, the problem that the positional deviation of the inkjet substrate affects the film thickness uniformity of a material film is avoided, and the quality of an OLED device 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 inkjet control terminal, an inkjet printing device, a computer device 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 each pixel pit on the glass substrate by means of inkjet printing through the inkjet head of the inkjet printing device to form a layer of material film. [0003] The film thickness uniformity of the material thin film is an important indicator for examining the OLED manufacturing process. Poor film thickness uniformity may affect the quality of OLED devices. [0004] During inkjet printing, due to various reasons, the inkjet head may not be ...

Poor film thickness uniformity may affect the quality of OLED devices

[0004] During inkjet printing, due to various reasons, the inkjet head may not be aligned with the pixel pits of the glass substrate, causing the ink ejected from the inkjet head to drop outside the pixel pits, causing each pixel on the glass substrate to be misaligned. The ink material in the pit is uneven, which affects the uniformity of the film thickness of the material film, and accordingly affects the quality of the OLED device

[0005] Therefore, there are problems affecting the quality of OLED devices in the current OLED device manufacturing process.
