The trio of units will be LCD, outsourcing operations and next-generation TVs, Reuters reports.
Sony introduced the measure following eight straight years of losses posted by its Bravia arm. The company will make an official announcement about the restructure tomorrow.
"By dividing into three divisions, we will make clearer the mission and responsibilities of these," said Sony spokesperson Ayano Iguchi.
It was previously rumoured that Sony was considering pulling out of the television market following tough competition from Samsung and budget manufacturers. The firm's Brava sets are generally rated as some of the best in the industry.
Sony will announce its quarterly financial results on November 2.
