Patent ID: 7515125

Claim:
An electronic device comprising: a light emitting module comprising: a pixel section over a substrate, and comprising: a current control TFT and a light emitting element comprising first and second electrodes, and a light emitting layer between the first and second electrodes, and over and electrically connected to the current control TFT; and a sensor section over the substrate, and comprising a photodiode; an insulating film covering an end portion of one of the first and second electrodes, covering the sensor section, and below the light emitting layer; a protective film over the insulating film, and covering the pixel section and the sensor section; a correction circuit and a driver circuit mounted in a printed wiring board, electrically connected to the pixel section and the sensor section through wirings; wherein the correction circuit adjusts luminance of the light emitting element according to environmental illuminance sensed by the sensor section and for keeping a ratio of the luminance to the environmental illuminance at a constant value by the correction circuit, wherein the sensor section is disposed outside the pixel section.
