Abstract:
A liquid crystal display device is disclosed utilizing two or more display panels stacked on top of each other. In a dual panel configuration, the first display panel may be comprised of color pixels and the second display panel may be comprised of contrast pixels. The color pixel in the first display panel has a corresponding contrast pixel in the second display panel wherein said contrast pixel is larger in terms of length and in size than the corresponding color pixel. The liquid crystal display device may also switch to a mode that uses an expansion method of contrast pixels to reduce image displacement. Further disclosed is a configuration where the relative position of the first display panel and the second display panel may be adjusted to align the corresponding color and contrast pixels when viewing the display in oblique angles.
