A pattern display apparatus comprising a rotary or stationary display member, to the outer surface of which is mounted a flexible organic electroluminescent device. The EL device is capable of displaying a character, a figure, a mark, an indica, and/or a pattern. In one embodiment the EL device is applied to the spinning reel of a gaming/ gambling/ fruit machine. In another embodiment the device is used in point-of purchase advertising. The EL device can be driven by a low voltage to emit bright light and is also capable of emitting light in multiple colours. Therefore, the problems (over heating, high power use, etc) in the using light bulbs in conventional pattern display apparatus, using light bulbs, do not arise. |
