Tap "Settings."
Tap "Brightness."
Touch the brightness slider and drag it to the right to increase the backlight brightness.
If the iPod touch backlight isn't bright enough for you, adjust the settings and brighten the screen. Increasing the brightness makes it easier to see pictures, read email and text messages, see Web pages in Safari, watch movies and much more. There is no physical switch on the iPod touch to control brightness, so you'll need to change the device's brightness settings in the Settings app.
