What is the name of the led display? Don't you have a Chinese name?

Light-emitting diode is called led for short. Diodes made of compounds of gallium (Ga) with arsenic (As), phosphorus (P), nitrogen (N) and indium (In) can emit visible light when electrons and holes recombine, so they can be used to make light-emitting diodes. Used as an indicator light in circuits and instruments, or as a text or digital display. Gallium arsenide phosphorescent diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and indium gallium nitride diodes emit blue light.
