While I agree with the other comments regarding monitor calibration and laptop use for image editing, I would like to suggest that there may be something else at work here to some degree.
When you review your image on the camera lcd, you are seeing a jpeg preview embedded in the raw file that is applying any image adjustments you might have selected in-camera. These adjustments include color space, picture controls, noise reduction, etc. that will not be automatically applied to the RAW file on import unless you are using the camera manufacturer's own raw converter. Using CS6, you will be applying the adobe standard profile to the raw image by default, and that can often produce a duller/flatter image than what you see on the camera lcd depending on the quality of the profile used by ACR for your camera. This is actually normal behavior to some degree. My experience is Nikon centric and I have no experience with Panasonic so your mileage may vary.
