Samsung has agreed to invest $110m in Sharp as part of an effort to strengthen its component supply chain.
The electronics giant said that its Japanese branch acquire a three percent share in the Sharp's voting stock.
Once completed, the deal will make Samsung Sharp's fifth-largest shareholder, ahead of, among others, Qualcomm.
Sharp said that the focus of the investment will be LCD displays. The company said that it will be using the money to build large-scale displays for use in Samsung's television sets as well as smaller screen form-factors which will be used for mobile devices and notebooks.
A second piece of the $110m investment will be devoted to the development and construction of new facilities which will handle LCD hardware manufacturing. The plan will play out through the end of 2015.
Sharp has had a long and occasionally rocky history in the LCD market. In 2010 the company was among the firms named in a high-profile price fixing scandal.
For Sharp, the deal will provide a much-needed infusion of capital as the company works to stabilise its position in the market.
In addition to the investment from Samsung, the company announced a corporate shake-up which will see new executives named in its products and devices units as well as a new senior executive managing officer.
