Abstract

This invention relates to a detachable display 10, in particular to a detachable liquid crystal display for an electronic device. The display 10 has a first plate 12, a second plate 14 parallel to the first plate 12, and a layer of liquid crystal material 16 between the first plate 12 and the second plates 14. So that the liquid crystal material 16 can be addressed, a plurality of X address lines 20 are provided on the first plate 12, and a plurality of Y address lines 22 are provided on the second plate 14. The X address lines 20 and the Y address lines 22 are each respectively connected to X contacts and Y contacts, the X contacts and Y contacts being positioned along a single connecting edge 32 of the display, so that the display can be connected/disconnected to/from a matching connector by simply sliding connecting edge 32 of the display 10 into/out of the connector.
