The purpose of this study is to solve the problems of current Web display technology, i.e., a single user can only work collaboratively with a single remote user through remote video conferencing and desktop mirroring, which does not meet the requirements of multi-user massive information sharing display, and does not support the high-resolution display of massive images, and so on. This work studies the technology of ultra-high resolution display on the splicing display screen of users of large-scale images based on Web clusters, according to the characteristics of multi-user massive information sharing display and the difficulty of display. The experimental results show that the proposed Web cluster parallel splicing massive image display technology is effective, and it can provide a feasible solution for the high-resolution display of massive images of multiple remote users on the splicing display.
