LIGHT-EMITTING MODULE AND DRIVING METHOD THEREFOR, AND OPTICAL SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a low power consuming light-emitting module excellent in visibility. SOLUTION: This is a light-emitting module comprising a light-emitting device including at least a pixel part 101 and a sensor part 104 on the same insulating body, and comprises means for detecting illuminance of a use environment by the sensor part 104, adjusting the emitted light intensity of the light- emitting element according to the illuminance, and keeping a ratio of the emitted light intensity to the outside environment constant. Thus, it is possible to obtain a light-emitting module permitting a display with proper brightness even if illuminance of the outside environment changes.
