Abstract

We developed a 24-bit color volumetric display based on light emitting diode (LED). This volumetric display consists of 8 × 8 × 8 LEDs array and can represent 24-bit color three-dimensional images. The light intensity of the LEDs is gradated by the pulse width modulation method. We designed a control circuit of the volumetric display with the field programmable gate array. We succeeded in displaying 24-bit color three-dimensional moving image.
