Abstract

Modular displays and methods of assembling modular displays are disclosed. The displays include a display element and a base element. The base element includes a light source configured to inject light into the display element, and electronics to drive the display element when the display element is attached to the base element. The display element includes a lightguide and a display panel, such as a liquid crystal display (LCD) panel. The base element further includes a receptacle configured to accept the display element and couple the light source to the lightguide, and couple the electronics to the LCD panel. The display element and the base element can be removably attached to each other. The base element and the display element can each be configured so that different display elements can be attached to the same base element, providing flexibility of modular display design.
