1. A display screen unit comprising:
- a first touchscreen component layer disposed on a first side of the display screen unit, the first touchscreen component layer adapted to allow display of a first displayable keyboard embedded within the first touchscreen component layer when the display screen unit is positioned in a first orientation relative to a display device, wherein when in the first orientation, the first touchscreen component layer is located directly over a display area of the display device;
a second touchscreen component layer disposed on a second side of the display screen unit, the second side being opposite to the first side, and the second touchscreen component layer adapted to provide display of a second displayable keyboard embedded within the second touchscreen component layer when the display screen unit is positioned in a second orientation relative to the display device, wherein when in the second orientation, the second touchscreen component layer is not located directly over the display area of the display device; and
a light modulator unit disposed between the first touchscreen component layer and the second touchscreen component layer, the light modulator unit adapted to cause the first displayable keyboard to be displayed by causing opacity in portions of the first touchscreen component layer and to cause the second displayable keyboard to be displayed by causing opacity in portions of the second touchscreen component layer.
