[0009] The control module can generate an image of a first size when in the first position, and can generate an image of a second size larger than the first size when in the second position.

[0010] The control module may include a display source; a transmittance module disposed on the cover glass; a reflector that reflects an image generated from the display source to the transmittance module; and an adjuster that varies the reflector to a first position or a second position.

[0011] The first position may be the position of the reflector when the reflector generates an image of the first size in the transmittance module.

[0012] The second position may be the position of the reflector when the reflector creates an image of the second size in the transmittance module.

[0013] The control module may further include a controller for controlling the display source and transmittance module and the regulator.

[0014] The controller drives the display source and drives the transmittance module so that the transmittance module can vary the pattern area.

This mode may be a small screen mode.

[0186] An example of a digestion mode is that the controller (90) can turn on the left display (90A) and the display source (30), turn on the left cell (44A) and the first cell (42), and keep the second cell (43) off.

[0187] Another example of a digestion mode is where the controller (90) can turn on the right display (90B) and display source (30), turn on the right cell (44B) and the first cell (42), and keep the second cell (43) off.
