In　response　to　the　high　hardware　requirements　of　traditional　touch　input　systems,　this　paper　proposes　a　new　system　for　touch　input　based　on　In-Graphic　recognition.　Unlike　In-Cell,　On-Cell　and　other　hardware-based　touch　input　systems,　this　system　uses　the　method　of　hiding　the　input　information　in　the　graphic　(In-Graphic),　and　then　uses　an　algorithm　to　identify　the　content　with　the　logo　in　the　display　image　and　complete　the　input　function,　which　is　a　touch　input　system　that　relies　on　software　algorithms.　The　system　can　make　a　medium　to　large　size　screen　into　a　smart　screen　with　touch　input　function　with　little　increase　in　hardware　cost,　and　realize　a　multi-purpose　screen,　greatly　enhancing　the　user　experience.　©　2022,　John　Wiley　and　Sons　Inc.　All　rights　reserved.
