Abstract
A liquid crystal display module defines a housing of essentially C-shaped cross-section for improved economy and for connection, protection, and support of the liquid crystal display and backlighting elements. Additionally, the drivers for the LCD may be so located by this invention, as to make room for a more intense light source to illuminate the LCD display. Also, the LCD module may exhibit a software variable color display through the use of one or more white or different color light sources and color polarizers. The invention also includes an improvement to the conventional means of applying printed circuitry to the unique housing.
