An information processing device for processing various kinds of information such as a mobile phone that allows an operator facing the device and other persons to view images on display screens in an easy manner. If a CPU determines that a mobile phone has entered a two-screen state in accordance with an ON signal from an opening sensor, the CPU then determines whether “split-screen display” is preset by a user. If the CPU determines that “split-screen display” is set, a display control part sends image signals to a liquid crystal display and a liquid crystal display in accordance with this determination. Accordingly, a previously displayed image is displayed upside down on a first display screen, and the same image is displayed in a normal state (not upside down) on a second display screen.

Optical and electronic means of addressing are combined to flash bit-sliced images rapidly in a sequential manner to achieve enormous reduction in circuit as well as cost of data drivers in display devices. Also, light source i.e. backlight or front light switching scheme is used to reduce power consumption of light source in display devices for both static and dynamic images with high contrast. Bit slice addressing (BSA) preserves colour purity of images at all angles in fast responding liquid crystal displays with simple data drivers. Colour purity of images is also preserved at all angles of view due to a viewing angle characteristic of bit slice addressing that is independent of gray shades.

The occurrence of crosstalk in a display device which performs 3D display is suppressed. When 3D display is performed, part of a plurality of pixels perform desired color display and the other part of the plurality of pixels perform black display. Thus, as compared to the case where all of a plurality of pixels perform desired color display, the occurrence of crosstalk can be suppressed. A plurality of pixels which perform desired color display are changed depending on the display state. Therefore, as compared to the case where a plurality of pixels which perform desired color display are fixed when 3D display is performed, the display device can have a longer period until display change in a pixel becomes obvious (a longer lifetime) and variations in display among the plurality of pixels can be reduced.
