Necklace worn device for displaying short moving or static images

Abstract

A necklace worn device for displaying short moving or static images in continuous loop based on the detection of the motion of wearers comprises a housing and a circuit board assembly. The housing is provided with a transparent window on one side thereof. The circuit board assembly provided detachably in the housing includes a pixelated display for displaying images, a non-volatile flash memory for storing images and other additional data, a microprocessor for processing the stored images and setting parameters, at least a motion detection switch activating the necklace worn device, a wireless transmitting and receiving unit for sending or receiving images, at least a rechargeable battery for power supply, and at least a control button for controlling the wireless transmitting and receiving unit and setting the parameters. The pixelated display is preferably an organic light emitting diode display and is provided under the transparent window of the housing.
