LIGHT DETECTION MODULE, LIGHT DETECTION CIRCUIT, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2019/041814

A1

A light detection module comprises a detection sub-circuit (110), a comparison sub-circuit (120), and a shielding layer. The shielding layer comprises at least one shielding element (121). The detection sub-circuit (110) comprises a first photosensitive element, and is configured to output a detection signal according to light received by the first photosensitive element and an input signal of the detection sub-circuit (110). The comparison sub-circuit (120) comprises a second photosensitive element, and at least one shielding element (121) in the shielding layer covers at least the second photosensitive element. The comparison sub-circuit (120) is configured to output a comparison signal according to an input signal of the comparison sub-circuit (120). The structure of the first photosensitive element is the same as that of the second photosensitive element, such that the two photosensitive elements have the same response to light and the same response to the environment.
