Back-lit liquid crystal display, in particular for use as a display module behind the operating panel of a large domestic appliance

摘要

A module of a back-lit liquid crystal display, as is used in particular in the operating panel of a large domestic appliance, is simple from a production procedure point of view, and is spatially compact and has close tolerances in regard to the installation dimensions. Further the module has good illumination of a transmissive liquid crystal cell, when a light guide panel is disposed in a trough-shaped reflector member and the liquid crystal cell is disposed at a small spacing relative to the coupling-out surface of the panel on the side walls of the trough-shaped member. A frame engages over the configuration in a cover-like manner and determines a height of the module in regard to its positively locking anchorage in the circuit board on which the trough-shaped reflector member then resiliently rests.
