Offset correction method, device and system for glass substrate

Abstract

The invention relates to a glass substrate offset correction method, a glass substrate offset correction device, a glass substrate offset correction system, computer equipment, and a computer-readable storage medium, wherein the method includes: detecting and acquiring the offset set on the glass substrate Mark the measured position coordinates in the original coordinate system; correct the original coordinate system according to the measured position coordinates and the expected position coordinates marked in the original coordinate system, and obtain the corrected corrected coordinate system; use the corrected coordinate system as the inkjet Printed coordinate system, corrected for glass substrate offset. The above method corrects the original coordinate system to the corrected coordinate system as the inkjet printing coordinate system through the detected position coordinates and estimated position coordinates of the logo on the glass substrate in the original coordinate system, so as to realize the offset of the glass substrate Compensation correction to improve the accuracy of the position of ink droplets falling on the glass substrate.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a glass substrate offset correction method, a glass substrate offset correction device, a glass substrate offset correction system, computer equipment and a computer-readable 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. According to the characteristics of the inkjet printing process, the uniformity of the film thickness of the ink material filled in th...

Problems solved by technology

[0003] In the existing inkjet printing process, due to the operating habits of the personnel and the lack of equipment functions, when the glass substrate is placed on the inkjet printing platform, the position of the glass substrate is prone to shift, resulting in During the process, if the ink droplet deviates from the pixel pit on the glass substrate, please refer to figure 2 shown

Under such circumstances, the OLED device produced by the inkjet printing process will be less effective due to the uneven film thickness of the ink material.
