Abstract
Abstract A portable computer is configured to accept removable modular display panels of different types that plug into a structure hinged to the body of the computer. Each display panel has a sliding engagement means fixed along a lower edge, and the hinged structure has a mating sliding engagement means along an upper edge and parallel to the axis of the hinge, allowing a display panel to engage and disengage in the direction of the axis of the hinge. In another aspect of the invention, in the motion of engaging a display, a two-part, multi-pin electrical connector is also engaged, for conveying control signals to the display. In an embodiment of the invention, display modules adaptable to the computer have a code stored in a memory device that is accessible on start-up by the computer, to identify and load a display driver routine capable of driving the display module assembled to the computer.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
182 words
A general-purpose computer comprising: body structure means for housing and supporting computing elements, memory elements, and input elements of said computer; removable flat-panel display means for providing a display screen for said computer, said flat-panel display means having a first slidable engagement means mounted along a first edge for joining said flat-panel display means to said computer; mating electrical connection means for providing display control signals to said flat-panel display means; and mounting structure means having a horizontal portion pivotally attached to said body structure means along a pivot axis and a second slidable engagement means for engaging said first slidable engagement means mounted to the horizontal portion, the engagement direction for said second slidable engagement means being substantially parallel to the pivot axis, said mounting structure means for receiving and holding said flat-panel display means as a hinged unit closable over said body structure means and openable to provide said display screen to a user; said first and second slidable engagement means configured to engage and disengage by moving said display means in a direction substantially parallel to said pivot axis.
Claim 2
Dependent Claim
182 words
A general-purpose computer comprising: body structure means for housing and supporting computing elements, memory elements, and input elements of said computer; removable flat-panel display means for providing a display screen for said computer, said flat-panel display means having a first slidable engagement means mounted along a first edge for joining said flat-panel display means to said computer; mating electrical connection means for providing display control signals to said flat-panel display means; and mounting structure means having a horizontal portion pivotally attached to said body structure means along a pivot axis and a second slidable engagement means for engaging said first slidable engagement means mounted to the horizontal portion, the engagement direction for said second slidable engagement means being substantially parallel to the pivot axis, said mounting structure means for receiving and holding said flat-panel display means as a hinged unit closable over said body structure means and openable to provide said display screen to a user; said first and second slidable engagement means configured to engage and disengage by moving said display means in a direction substantially parallel to said pivot axis.
Claim 3
Dependent Claim
90 words
A general-purpose computer as in claim 1 wherein said mating electrical connection means comprises a first portion of a multi-pin electrical connector mounted in a second edge of said flat-panel display means, forming substantially a right angle with said first edge, and a second portion of said multi-pin electrical connector mounted in a vertical portion of said mounting structure means at one end of said horizontal portion, said first and second portions of said multi-pin electrical connector engageable by the motion that engages said first and second slidable engagement means.
Claim 4
Dependent Claim
61 words
A general-purpose computer as in claim 1 wherein said first and second slidable engagement means comprise at least two pairs of shafts attached to one of said mounting structure means and said flat-panel display means, and two pairs of bores configured to mate with said shafts and attached to the other of said mounting structure means and said flat-panel display means.
Claim 5
Dependent Claim
70 words
A general-purpose computer as in claim 1 further comprising a snap-in structure extending from one of said flat-panel display and said mounting structure means and an engagement slot in the other of said flat-panel display and said mounting structure means, configured to engage and snap together as said flat-panel display and mounting structure means fully engage, thereby holding said flat-panel display means firmly in engagement with said mounting structure means.
Claim 6
Dependent Claim
28 words
A general-purpose computer as in claim 4 wherein said snap-in structure comprises release means for unlocking to release said flat-panel display from said mounting structure means for removal.
Claim 7
Dependent Claim
