LCD module with separate display and electronics - uses two circuit boards linked by printed circuit board connecting into flexible multi-conductor connectors on boards

摘要

The module is formed from two readily separable parts, one being the display panel incorporating the liquid crystal cells and the other the electronic circuit which controls and drives the display. The electrical connections between the two parts use a system of separable connections having a flexible joint with multiple conductors. The flexible joints connect to a printed circuit board which connects the electronic control circuit to the display cells. The assembly is mounted in a box, having a rectangular window in one end, with the liquid crystals facing the window. The opposite end of the box is closed by the printed circuit board which couples the two parts of the unit. A light source is placed behind the liquid crystals for display in low ambient light conditions.
