LIGHT-EMITTING DEVICE |
| 摘要 |
A light-emitting device in which variation in luminance among pixels is suppressed. The light-emitting device includes a pixel; a first circuit configured to generate a signal containing information on a value of current extracted from the pixel; and a second circuit configured to correct an image signal in accordance with the signal. The pixel includes a light-emitting element; a transistor for controlling supply of the current to the light-emitting element in accordance with the image signal; a first switch configured to control connection between a gate and a drain of the transistor or between the gate of the transistor and a wiring; and a second switch configured to control extraction of the current from the pixel. |
