Three-dimensional display device for manufacturing e.g. indicator instrument, has LEDs, whose turning on and off are controlled based on position angle of column relative to rotational axis, where angle is detected by detection circuit

摘要

#CMT# #/CMT# The device has a color LED column (1) rotating along a rotational axis (4) of a motor (5) due to an action of the motor, where the rotational axis defines a rotating surface (6). The axis projects a stable image determined by rotation of the column, and by turning on and turning off different LEDs forming the column. The turning on and turning off are controlled by an electronic circuit (2) based on a position angle of the column with respect to the rotational axis, where the angle is detected by a detection circuit (3). #CMT#USE : #/CMT# Device for three-dimensional displaying of information e.g. text/message or image/graphics, in manufacturing of an indicator instrument and an image or sound recording transmitting and reproducing apparatus. #CMT#ADVANTAGE : #/CMT# The configuration of the color LED column presents improved radiation characteristics for generating a series of graphical symbols displaced in a circular manner with visibility angle of 360 degree without any support, thus authorizing projection of three-dimensional image in a circular manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of an object in relation with a method and device for displaying information. 1 : Color LED column 2 : Electronic circuit 3 : Detection circuit 4 : Rotational axis 5 : Motor 6 : Rotating surface.
