Apple is expected to take the wraps off a new version of its iPhone later on Wednesday.
Some analysts also think Apple plans to announce a smaller iPad to safeguard its market share as rivals including Samsung Electronics and Amazon.com Inc begin selling cheaper, seven-inch tablets.
AU Optronics, the world's No.4 LCD maker, will ship about 400,000 to 500,000 panels in September for Apple's reported small-sized iPad, Taiwan's DigiTimes said, citing industry supply chain sources. http://link.reuters.com/haj62t
LG Display will supply as many as 600,000 panels to Apple, the website reported.
DigiTimes, quoting sources, said supplies for a 7.85-inch iPad began in June, with a monthly volume of several hundred thousand.
The latest generation iPad has a 9.7 inch screen.
AU Optronics and LG Display could not be immediately reached for comment.
The report comes on the day that the U.S. government asked a federal court to impose a $1 billion fine on AU Optronics over its role in a cartel that fixed the prices of LCD panels over a number of years.
AU Optronics shares were up 3 percent at $3.74 on the New York Stock Exchange. LG Display shares closed up 1.5 percent in trading in Seoul.
