REMOTE CONTROLLED VIRTUAL DISPLAY

Conventional methods of displaying images or messages to public are using LCD display and dot-matrix LED board. Remote Controlled Virtual Display is a device that projects an image, time or messages as if the images are floating in the air. The floating image is received because of human eye limitation. Actually the floating images emerge by synchronizing LED'S blink to form an image at particular time and rate. The Remote Controlled Virtual Display is an electronic device which has a series of LEDs on board that rotate with the help of a motor to give an illusion of a watching a clock ( Digital or Analogue ). This requires a DC motor which rotates the PCB connected to it with sufficient speed, so as to create the illusion. The LEDs are connected to a microprocessor, which is so programmed to switch ON and OFF the LEDs in a sequence and with a time delay to approximately match with the rotating speed of the motor. The synchronization of DC motor speed and LED blink cause the image visible to human eyes. So the desired image such as clock, date or symbol can be programmed and displayed.
