ABSTRACT:
An assembly for dissipating heat from an active matrix liquid crystal display module while avoiding developing thermally induced mechanical stresses which can adversely affect the electro-optical properties of the liquid crystal material is disclosed. The module is affixed to a circuit board containing electrical leads for connection to drive electronics, in a way such that the substrate containing the active matrix elements is suspended through a window or through-hole in the circuit board and is sunken or nested into a soft elastomeric gel which is electrically non-conductive but thermally conductive. The gel provides the requisite thermal conductivity to dissipate the heat via a heat sink with which the gel is in thermal contact.
