OLED may replace VLC for optical wireless communication
Visible light communication (VLC) system is an alternative to radio based wireless network. It has dual purposes: providing indoor lighting and using light waves for data transmission. VLC uses modulated light as the data carrier, while the visible spectrum provides light. Using VLC for data transmission has some advantages. It provides good bandwidth; It provides […]
LED display P several good
P in the LED display generally represents the pixel spacing, and the value behind P mainly refers to the distance between two LED beads, which is often referred to as the point spacing. If the value of point spacing is smaller, the higher the unit pixel, the clearer the image quality and the more expensive […]
