Patent ID: 7215390

Claim:
A back-lit liquid crystal display, comprising: a frame having spring noses; a circuit board having conductor tracks; a liquid crystal cell disposed under said frame and electrically and mechanically connected to said circuit board; a light-guide panel having a light passing there-through transversely with respect to a viewing direction and disposed under said liquid crystal cell; a trough-shaped reflector member accommodating said light-guide panel and at a small spacing above said light-guide panel carrying said liquid crystal cell, said trough-shaped reflector member having a bottom with a slot-shaped aperture formed therein; a light source, electrically and mechanically connected to said conductor tracks of said circuit board, radiates the light laterally into said light-guide panel; said frame, said circuit board, said liquid crystal cell, said light-guide panel, said light source, and said trough-shaped reflector member forming a modular structure defining a display module for use behind an operating panel of a domestic appliance; said trough-shaped reflector member resting in an elastically supported relationship on said circuit board; said frame being a cover-shaped frame determining a structural height of the display module; said light-guide panel having an angularly extending limb engaging into said slot-shaped aperture; said circuit board having at least one aperture formed therein beneath said slot-shaped aperture, said light source being disposed in or under said aperture and radiating the light into said angularly extending limb, said light source connected to said conductor tracks on a rear side of said circuit board, remote from said frame; and said frame rigidly latched with said spring noses in opposite relationship to elastic support of said trough-shaped reflector member.
