[0036] The applicant has found that the existing LCD screen inkjet printing sequence recognition has long been done manually. There are certain uncertainties in manual recognition, such as the decrease in sensitivity caused by repetitive work, which leads to recognition errors, and the recognition history is difficult to store and save formally. In addition, due to the small screen size and unclear inkjet printing, recognition accuracy has always been a difficult problem to solve. In addition, since the production is based on screens of different sizes, it is difficult for fixed positioning molds to meet the universal requirements of production.

[0037] In order to solve the above problems, the utility model provides a more general inkjet printing sequence recognition device and system applicable to various screen sizes. Embodiment 1
