Abstract:
A tiled flat-panel modular display system includes an array of display modules which contain thin seal liquid crystal displays. Each one of a plurality of module alignment devices attach a respective display module to a large base plate. A frame is connected to the base plate and surrounds the base plate and display modules. A global cover glass assembly disposed above the display modules encloses and protects the display modules. Included in each of the display modules is a light source configuration of a light box and a light box cover which utilizes global light sources that provide efficient uniform backlighting of the corresponding display. The alignment devices permit alignment of the display modules with respect to each other and to a global black mask disposed in the global cover glass assembly to achieve a display system that is seamless in appearance. The tiled display system further utilizes compensation electronics to achieve uniform contrast and transmission characteristics in each of the thin seal displays. In addition, the display system utilizes display circuitry that achieves an improvement in optical performance over conventional displays.
