要在黑莓解决这个问题，我用code如下：

To solve this problem in blackberry I used code below:

import net.rim.device.api.system.Backlight;
import net.rim.device.api.util.DateTimeUtilities;

int MAX_BACKLIGHT_TIMEOUT_SECS = 255;

....

Backlight.setTimeout(MAX_BACKLIGHT_TIMEOUT_SECS);
Timer timer_ = new Timer();

timer_.scheduleAtFixedRate(new TimerTask() 
{
    public void run() 
    {
        Backlight.enable(true);
    }
}, 
(MAX_BACKLIGHT_TIMEOUT_SECS - 1) * DateTimeUtilities.ONESECOND, 
(MAX_BACKLIGHT_TIMEOUT_SECS - 1) * DateTimeUtilities.ONESECOND);
