TOKYO, Jan 31 (Reuters) - Japan's Toshiba Corp (6502.T: اقتباس) is expected to report a five-fold rise in October-December operating profit on Monday on robust sales of NAND flash memory used in smartphones and tablets.
Sales of small to mid-sized liquid-crystal display panels are also expected to have benefited from the boom in high-end mobile devices led by Apple's (AAPL.O: اقتباس) iPad and iPhone.
Toshiba, which makes everything from nuclear power plants to household appliances, also competes with Hewlett-Packard (HPQ.N: اقتباس) and Dell DELL.O in personal computers.
Toshiba is the world's second largest supplier of NAND chips after South Korea's Samsung Electronics (005930.KS: اقتباس), which reported its weakest profit in six quarters, but is expected to post an improvement in results this year as the smartphone market expands further. يتبع
