Japanese game maker Nintendo Co. is introducing an upgrade of its 3DS handheld machine sporting a screen nearly twice as big as those on sale.

The Kyoto-based maker of the Super Mario games and Wii home console said Friday the Nintendo 3DSW LL goes on sale in Japan and Europe July 28, and in the U.S. from Aug. 19.

It will sell in Japan for 18,900 yen ($236), and $199.99 in the U.S.

The 3DS, which has a touch panel and delivers 3-D imagery without special glasses, has two screens -- one is 3.53 inches and the other is 3.02 inches.

The LL version' screens are 4.88 inches and 4.18 inches, according to the company. Screen inches refer to the diagonal measurement so LL screens are 1.9 times bigger.
