2018 Update - Please don't use this info !

I'm leaving the below post for reference purposes.

Please read Apple's documentation Human Interface Guidelines - Launch Screens for details on launch screens and recommendations.

Thanks

Yes. In iPhone/iPad development the Default.png file is displayed by the device automatically so you don't have to program it which is really useful. I don't have it with me, but you need different PNGs for the iPad with specific names. I googled iPad default png and got this info from the phunkwerks site:

iPad Launch Image Orientations

To deal with various orientation options, a new naming convention has been created for iPad launch images. The screen size of the iPad is 768×1024, notice in the dimensions that follow the height takes into account a 20 pixel status bar.

Filename Dimensions

• Default-Portrait.png * — 768w x 1024h
• Default-PortraitUpsideDown.png — 768w x 1024h
• Default-Landscape.png ** — 1024w x 748h
• Default-LandscapeLeft.png — 1024w x 748h
• Default-LandscapeRight.png — 1024w x 748h
• iPad-Retina–Portrait.png — 1536w x 2048h
• iPad-Retina–Landscape.png — 2048w x 1496h
• Default.png — Not recommended

*—If you have not specified a Default-PortraitUpsideDown.png file, this file will take precedence.

**—If you have not specified a Default-LandscapeLeft.png or Default-LandscapeRight.png image file, this file will take precedence.

This link to "Apple's Developer Library" is useful, too.
