Abstract
PURPOSE: To obtain a small-sized voltage display element whose operating method is simple, by applying the p-n junction of a semiconductor light emitting element with a forward voltage, and then forming a light emission area which expands linearly corresponding the variation of the applied voltage.
CONSTITUTION: A voltage display element consists of metallic electrodes 1 and 2, a p-GaAs layer 3, an n-GaAs layer 4, a p-n junction 5, and an infrared/visible conversion fluorescent material layer 6. When a voltage V to be measured is applied between metallic electrodes 1 and 2, the diffusion length of a small number of carriers in the p type layer varies in a direction (x) corresponding to the level of the forward voltage applied to the p-n junction 5, and a recombination light emission area varies corresponding to the level variation of the voltage. Light emitted by recombination whose center is 9,400Å in wavelength is converted into visible light through the infrared/visible conversion fluorescent material layer 6. Consequently, a small-sized voltage display element whose operating method is simple is obtained.
