<p>A display for extensive playing/recording, includes LEDs mounted on plastic tubes with diffusers in a matrix arrangement, in which each LED/diffuser/tube unit provides an image point. The length of the tubes and the spacing between them is variable and the tubes are internally hollow and in them the cabling (power supply etc.) are accommodated. The LEDs are mounted at the ends of the plastic tubes together with a rounded adjustable diffuser (like a sealing cap), so the light point can also radiate laterally. The playing/recording is controlled by a central appliance and according to the LEDs which are used, both monochrome and color films videos etc. can be shown.</p> |
