Enlargeable Portable Computing Displays

Disclosed is a method of design which involves multiple viewing screens where
subsequent viewing screen(s) can be stored (hidden) or exposed (shown).

Figure 1

     Fig. 1 shows a laptop with the second screen in the "closed" position.
Fig. 2 shows how a user can pull on the top of the screen casing to reveal and
activate the second screen. Once the second screen is pulled to the top, it
turns on and software will re-flow the display to utilize the extra height.

Figure 2

     The example figures show the screen enlarging approximately 2X of the
original screen height. It should be noted that this idea covers the full
range of enlargements to the original screen size, including integer multiples
(1 to N times larger) and fractional amounts (50% larger, etc...). This idea
can also extend to multiple screens all with the ability to become hidden or
shown and once shown, will work with each other to produce a larger viewing
area.

     A button or latch could release the screen and allow it to freely slide
in and out. When fully enlarged or enlarged to a set size, it locks into
place, turns on, and software will re-flow the display. It should also be
noted that the idea could encompass changes to the width of the screen as well
as the height. In addition, the screen doesn't necessarily have to be
rectangular in shape. It could be elliptical or some other shape.

     By making the screen enlarg...
