A laptop computer display module (28) for use in a clamshell type laptop computer includes a telescoping rail assembly (100) that enables the display module (28) to be extended upwardly from a keyboard module (24) of the laptop computer when the display module is rotated to an open position. A computer display panel (28) is rotatably mounted to a display support member (120) of the display module adjacent a top margin of the display panel (70) so that the display panel (70) can be manually swung away from the display support member (120) and toward a user of the laptop computer (20). The invention enables the display panel (70) to be positioned at a comfortable viewing angle without blocking access to the keyboard module (24) for typing and is particularly useful in depth-constrained workspaces such as airplane passenger seats, where the display support member (120) must be positioned at an acute angle relative to the keyboard module (24).

1. A laptop computer, comprising:a base unit having a generally tabular shape adapted for placement on a support surface, the base unit including a manual input device; and a display module rotatably connected to the base unit, the display module being openable and closeable by rotation of the display module relative to the base unit, the display module including: (a) a rail assembly, (b) a display support member mounted to the rail assembly for movement outwardly from the base unit, and (c) a display panel bordered by a top margin and a bottom margin, the display panel supported on the display support member for rotation of the display panel so that the bottom margin of display panel can be manually swung away from the display support member toward a user of the laptop computer after opening of the display module. 2. The laptop computer of claim 1 in which the display support member is movable along the rail assembly to a height above the base unit that is sufficient to allow the display panel to rotate to a comfortable viewing angle without blocking the manual input device of the base unit and to thereby allow a user to comfortably view the display panel while manually inputting data via the manual input device when using the laptop computer in a depth-constrained workspace.3. The laptop computer of claim 1, further comprising an articulating joint connecting the display panel to the display support member, and in which the articulating joint includes a torque joint that adjustably maintains an angular position of the display panel relative to the display support member.4. The laptop computer of claim 1 in which:the rail assembly includes first and second rails spaced apart in parallel relation; and the display support member includes a first slot and a second slot spaced apart from the first slot, the first and second slots sized and positioned to receive the first and second rails, respectively. 5. The laptop computer of claim 1 in which:the rail assembly includes a first rail and a second rail, the first and second rails spaced apart in parallel relation and rigidly attached to the display support member; and the rail assembly further includes first and second slots spaced apart in parallel relation, the first and second slots sized and positioned to receive the first and second rails, respectively. 6. The laptop computer of claim 1 in which the display module includes an articulating joint that rotatably interconnects the top margin of the display panel to the display support member.7. The laptop computer of claim 1 in which:the base unit includes a rear margin; and the display module is rotatably connected to the base unit along the rear margin. 8. The laptop computer of claim 1 in which the manual input device includes a keypad.9. The laptop computer of claim 1 in which the manual input device includes a pen tablet.10. The laptop computer of claim 1 in which the manual input device includes a pointing device.11. The laptop computer of claim 1, further comprising a latching device for releasably latching the display module to the base unit and preventing movement of the display support member along the rail assembly when the display module is closed.12. The laptop computer of claim 2 in which the display panel is manually rotatable to the comfortable viewing angle without blocking the manual input device when the display support member is rotated to a depth-reduction angle of greater than 30 degrees and less than 120 degrees relative to the base unit.13. The laptop computer of claim 4, further comprising an anti-skew mechanism that mechanically couples movement of the display support member along the first rail to movement of the display support member along the second rail, thereby preventing binding of the display support member and the rail assembly.14. The laptop computer of claim 5, further comprising an anti-skew mechanism that mechanically couples movement of the first rail within the first slot to movement of the second rail within the second slot, thereby preventing binding of the display support member and the rail assembly.15. The laptop computer of claim 12 in which the comfortable viewing angle is greater than 90 degrees and less than 150 degrees relative to the base unit.16. A laptop computer display module, comprising:a rail assembly including a hinge end adapted to be rotatably mounted to a base unit of a laptop computer so that the rail assembly extends outwardly from the base unit and so that the display module can be opened and closed by rotating the display module about the hinge end, the display module rotatable to a closed position in which the display module is folded against the base unit and an open position in which the display module extends from the base unit; a display support member attached to the rail assembly for movement away from the hinge end of the rail assembly when the display module is opened; a computer display panel having top and bottom margins; and an articulating joint connecting the computer display panel to the display support member adjacent the top margin of the computer display panel so that the bottom margin of the computer display panel can be manually swung away from the display support member and toward a user of the laptop computer when the display module is mounted to the base unit and opened. 17. The laptop computer display module of claim 16 in which the display support member is movable away from the hinge end of the rail assembly a distance sufficient to allow the computer display panel to rotate about the articulating joint to a comfortable viewing angle when the display module is installed on a base unit, without interfering with manual operation of a manual input device of the base unit, and to thereby allow a user to comfortably view the display panel while manually operating the manual input device in a depth-constrained workspace.18. The laptop computer display module of claim 16 in which the comfortable viewing angle is greater than 90 degrees and less than 150 degrees relative to the base unit.19. The laptop computer display module of claim 16 in which:the base unit is bordered by a rear margin that terminates in left and right ends; the rail assembly includes first and second elongate rails spaced apart and rotatably mountable to the base unit proximal of the respective left and right ends of the rear margin; and the display support member includes a first slot and a second slot spaced apart from the first slot, the first and second slots sized to receive the first and second rails, respectively. 20. The laptop computer of claim 16 in which:the rail assembly includes a first rail and a second rail, the first and second rails spaced apart in parallel relation and rigidly attached to the display support member; and the rail assembly further includes first and second slots spaced apart in parallel relation, the first and second slots sized and positioned to receive the first and second rails, respectively. 21.
