But that deal could be in jeopardy after Sharp claimed that these TVs aren't up to scratch. Sharp's legal papers claim that Hisense has broken US rules on electromagnetic emissions and made fraudulent claims about the picture quality of the TV sets.
Hisense strongly denies the accusations and says that it will "continue to manufacture and sell quality televisions under the Sharp brand", despite Sharp claiming the deal could destroy the Sharp brand.
Sharp signed the deal with Hisense in 2015 when it was in financial difficulty. Since then, the Taiwanese electronics company Foxconn has purchased a controlling stake in the company.
Following a cash injection from Foxconn, it seems Sharp now wants to regain control of the brand name in the United States - and this legal action could be the first step.
Sharp launched more than 50 HD and 4K TV ranges at the IFA trade show in September 2016, though we've yet to see any review samples.
When asked for comment, Sharp said that it will "be suing Hisense and its affiliated companies, but we refrain from commenting further since it is a pending lawsuit. This issue is only related to Sharp’s US TV business.”
Hisense said that "Sharp’s attempt to terminate the agreement is of no effect", and "categorically" denied all Sharp's claims.
