Portable computer - Figure 2 (U.S. Patent 6504707)
For decades, IBM was a pioneer in the portable computer market, introducing the venerable ThinkPad laptop brand–sold to Lenovo in 2005. And when Big Blue was still designing laptops, its engineers and designers came up with some pretty strange ideas.
The U.S. patent drawings in this gallery showcase four of those ideas:
A telescoping display designed for frequent fliers
A self-contained, pop-up magnifier to make the display larger
A scissor-hinge lid for the ultimate in display flexibility
A collapsible glare shield that looked like a giant, square ice cream cone.
While none of these ideas made it to market in their original form, they illustrate the creativity of IBM employees. They also provide a glimpse of current technologies that were being toyed with years ago–such flippable displays (found in many convertible, tablet laptops).
U.S. Patent number: 6,504,707
Filed: May 11, 2001
Issued: Jan. 7, 2003
Inventors: Hiroaki Agata, Kenshin Yonemochi, Takehiko Noguchi, Hisashi Shima, and John Peter Karidis
Assignee: International Business Machines Corporation (IBM)
In 2001, inventors from IBM designed a very unique laptop with a telescoping display.
According to the patent document:
“In consideration of the above described facts, it is an object of the present invention to provide a portable computer which is intended to be capable of adjusting the display’s height and angle without deteriorating the keyboard’s operability, and to make the operability be more favorable for a user in the adjustment of the display’s height even when the place for installing the portable computer is restricted int eh rear space or the upper space. ”
Figure 2 of the patent document illustrates how the display screen would extend up from the laptop’s lid.

What type of user did IBM think would want such a strange display? Thanks to Figure 11 we know. As shown here, the designers thought their innovation would make it easier to use a laptop in cramped spaces–such as those found on the seat-back trays on an airplane.

Self deploying magnifier for a portable computer display screen - Figure 1 (U.S. Patent 5991150)
U.S. Patent number: 5,991,150
Filed: Sep. 9, 1997
Issued: Nov. 23, 1999
Inventors: George Liang-Tai Chiu, Thomas Mario Cipolla, Fuad Elias Doany, John Peter Karidis, Rama Nand Singh
Assignee: International Business Machines Corporation (IBM)
In 1997, inventors from IBM designed a magnifier for people who have trouble seeing the information shown on laptop screens. What made this device unique? It was built into the laptop’s lid and “popped out” when the user opened the lid.
According to the patent document:
“The invention positions a flat optical magnifier such as a lens of the fresnel type in an optically enhancing position between the operator of the portable computer and the display screen so that th eimage at the computer operator side of the elens is greater than that present on the display screen.”
Figure 1 of the patent document illustrates how the magnifier would look with the display screen open.

Flexible monitor/display on mobile device - Figure 1 (U.S. Patent 6532147)
U.S. Patent number: 6,532,147
Filed: Sep. 24, 1999
Issued: Mar. 11, 2003
Inventor: Arthur R. Christ, Jr.
Assignee: International Business Machines Corporation (IBM)
In 1999, inventor Arthur Christ designed a laptop with a very interesting lid. Using two different hinge configurations, Christ’s design allowed the lid to flip completely around. This meant you could use the screen with the lid closed.
According to the patent document:
“A portable computer is provided which has a display screen mounted to a base by one or more flexible hinges, such as scissors type hinges or telescoping hinges, to provide flexibility of the operable positions of the display screen in relation to the base.”
Although Christ’s scissor hinges were impractical, the concept would eventually catch on. Convertible tablet/laptops would eventually adopt a rotating display lid that let people use the screen with the lid closed. And in September 2010, Dell introduced a Netbook with a touch-screen display that flips within traditionally hinged lid–like a picture in a frame.

Issued: May 28, 2002
Inventors: David Wayne Hill, David Andrew Sawin, and Tomoyuki Takahashi
Assignee: International Business Machines Corporation (IBM)
In 2002, inventors from IBM designed a “collapsible-light shield” for laptops.
According to the patent document:
“The light shield has four flexible panels that form a tubular shape when in use. One end of the light shield has a contoured viewing port through which the user may view the screen. The other end of the light shield has a ring-like elastic fastener that detachably secures to three sides of the computer display. Each panel has two bisecting fold lines about which the tubular light shield may be collapsed into a substantially flat profile that is a small fraction of its original size.”
Figure 1 of the patent document, shown here, illustrates how someone would typically use a laptop in a “brightly let environment.”
