Input/output device and driving method thereof |
摘要 |
An input/output device includes a pixel area; a light emission circuit provided in the pixel area and configured to emit light; and a photodetection circuit provided in the pixel area and configured to generate a voltage having a value corresponding to an intensity of incident light. The light emission circuit includes a drive transistor and a light emitting element. The light emitting element includes a first current terminal electrically connected to the source or the drain of the drive transistor and a second current terminal to which a first voltage is input, and emits light in accordance with a current flowing between the first and second current terminals. The light emission circuit includes a switching element including a first terminal to which a second voltage is input, and a second terminal electrically connected to the first current terminal of the light emitting element. |
