ABSTRACT:
A miniature image source includes a plurality of substrates, one formed of semiconductor material having an active matrix array and being relatively rough and the other being relatively smooth, a sealed space between the substrates containing liquid crystal material, electrically conductive members or terminal pads of the rough substrate being electrically and mechanically connected to electrically conductive members on the smooth substrate and are brought externally of the sealed space for exposure on the smooth substrate for external electrical connection. A method for making a miniature image source includes mechanically and electrically connecting electrical members of respective substrates using electrical material, sealing a space between the substrates for containing liquid crystal material using seal material, and elevating the temperature of the respective materials to activate first said electrical material and subsequently said seal material.
