Title:
ULTRAVIOLET DETECTION DEVICE AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2014/002591
Kind Code:
A1
Abstract:
An ultraviolet detection device comprises: a color change layer (401) which changes color according to the amount of ultraviolet light; a first color detection sensor (102) which detects the color of the color change layer (401); and a second color detection sensor (502) which detects the color of external visible light. By correcting an output value from the first color detection sensor (102) by an output value from the second color detection sensor (502), the amount of ultraviolet light can be accurately obtained as electronic information without being influenced by changes in the color of external incident light.
