Portable computer having an LCD projection display system

A portable computer comprising:

• a base housing having a top side, opposite front and rear side edge portions, and an opening extending through said top side and positioned forwardly apart from said rear side edge portion;
• a solid, relatively thin screen panel member having a non-mirrored front side surface and being secured to said rear side edge portion of said base housing for pivotal movement relative thereto between an open use orientation in which said screen panel member projects upwardly from said rear side portion of said base housing, with said non-mirrored front side surface of said screen panel member facing forwardly, and a closed storage and transport orientation in which said screen panel member extends across and covers said top side of said base housing with said non-mirrored front side surface of said screen panel member facing said top side of said base housing;
• and
• projection means for projecting a selectively variable image substantially exclusively onto said non-mirrored front side surface of said screen panel member when said screen panel member is in said open use orientation thereof, said projection means including:
• a lens structure supported at said opening in said top side of said base housing for movement, relative to said base housing and said screen structure, through said opening between a use orientation in which said lens structure projects above said opening and a storage and transport orientation in which said lens structure is recessed in said opening, said lens structure having a rear side surface positioned to face said non-mirrored front side surface of said screen panel member when said screen panel member and said lens structure are in said use orientations thereof, and a bottom side surface extending at an angle to said rear side surface of said lens structure,
• an LCD projection panel extending across and against said bottom side surface of said lens structure, said LCD projection panel being operable to create a selectively variable panel image thereon,
• an illumination structure operative to transmit light directly through said LCD projection panel and into said lens structure, wherein said lens structure directs said light substantially exclusively onto said screen panel member forming said selectively variable panel image thereon.
