MODULAR FRONT-LIT DISPLAY PANEL

摘要

A front-lit display panel includes a pixels units (10) attached to an assembly board at a plurality of pixel receiving positions arranged in a two-dimensional array. Each pixel unit has a layered structure including a sequence of a transparent conductor (20), an active layer (22) containing liquid-crystal-type molecules, and a rear conductive layer (24). Parts of the pixel unit (10) which lie on a side of the rear conductive layer (24) remote from the active layer (22) are designated as the "rear portion" of the pixel unit (10). Each pixel unit (10) also includes a first electrical connector (26) in electrical contact with the rear conductive layer (24) and a second electrical connector (28) in electrical contact with the transparent conductor (20). Both conductors (20, 24) extend to the rear portion of the pixel unit (10). Each pixel receiving position on the assembly board is provided with a pair of contacts adapted for making electrical contact with the first and second electrical connectors (26, 28) of one of the pixel units (10).
