Abstract: In an LCD assembly, a foldable support frame includes an upright stand member with one end pivoted to a base member and another end pivoted to a rear side wall of an LCD unit. A positioning unit is mounted on the stand member, and engages releasably the base member for positioning the base member at an unfolded position relative to the stand member. The positioning unit is operable for disengaging from the base member so as to permit turning of the base member for folding on the stand member. The stand member is turnable forwardly for folding on the LCD unit.
