A display provides increased contrast and resolution via first LCD panel energized to generate an image and a second LCD panel configured to increase contrast of the image. The second panel is an LCD panel without color filters and is configured to increase contrast by decreasing black levels of dark portions of images using polarization rotation and filtration. The second LCD panel may have higher resolution than the first LCD panel. A half wave plate and/or film is placed in between the first and the second panel. The panels may be directly illuminated or edge lit, and may be globally or locally dimmed lights that may also include individual control of color intensities for each image or frame displayed.

The present invention provides a data processing device connected with an intermission driving. The data processing device achieves a satisfactory power saving while ensuring a high level of display quality of the display device. Upon detection of non-data update in a frame buffer, the host calculates a next refreshing timing based on driving information obtained from a liquid crystal display device (LCD), sets a timer for a timeout after a length of time representing the calculated result, and then the host and the LCD shift to Intermission State 1. Thereafter, when the timer times out to bring the host back to Normal State and a data update at the frame buffer is detected, data for refreshing an display image in the LCD is transferred from the host to the LCD. If the amount of time representing the calculated result is longer than a predetermined baseline, a shift is made to Intermission State 2 which provides greater power saving than Intermission State 1.
