Abstract
A structure is formed by putting glass plates between a luminescence generating device and an electron emitting device so that a vacuum is formed in between. After in putting a high-voltage, an electron beam is emitted from the electron emitting device using low power. In the end, silicon quantum dots in the luminescence generating device are excited to generate a white light. The present invention has a good optoelectronic transformation efficiency.
