20130063407 | DISPLAY DEVICE - Disclosed is a display device that can compensate for variations of light-detecting element while securing a wide dynamic range of light sensors. This is a display device equipped with light sensors having operation modes for one frame period, which are: a sensor driving mode for obtaining sensor signals, a first correction data acquisition mode for obtaining a first correction data, and a second correction data acquisition mode for obtaining a second correction data. This display device further includes a memory that stores light sensor signal levels obtained, under a controlled ambient environmental condition, by driving the light sensors in the above-mentioned three modes as offset elimination data. A signal-processing circuit uses the first correction data and the second correction data, and the light sensor signal level corrected with the offset elimination data to correct the light sensor signal obtained in the sensor driving mode. | 03-14-2013 |
