    Abstract: A low-power display device is provided. The display device is provided with a plurality of display portions. A data driver circuit and an addition circuit are provided to have a region overlapping with the display portion. First analog data is output from the data driver circuit in the case where first digital data consisting of a first digital value is input to the data driver circuit, whereas second analog data is output from the data driver circuit in the case where second digital data consisting of a second digital value is input to the data driver circuit. The addition circuit generates analog data corresponding to digital data that has a high-order bit that is the first digital value and a low-order bit that is the second digital value, by adding the second analog data to the first analog data. An output terminal of the data driver circuit is directly connected to an input terminal of the addition circuit without through an amplifier circuit.

    Abstract: Common noise is reduced from light-receiving data. A display module includes a display apparatus and a reading circuit. Each of a first pixel and a second pixel adjacent to each other in the display apparatus includes a light-receiving element and a light-emitting element. The reading circuit includes a differential input circuit. Common noise generated when display data is supplied to a light-emitting element, for example, may affect a first light-receiving signal output by the first pixel and a second light-receiving signal output by the second pixel. A first current is generated using the first light-receiving signal and a ramp signal, and a second current is generated using the second light-receiving signal and a first potential. The differential input circuit is controlled so that the first current and the second current have the same current value, whereby common noise can be removed from the first light-receiving signal.

    Abstract: To achieve multifunctionality, a large number of components and the time and effort for implementing the components are required, which leads to an increase in the manufacturing cost and a reduction in yield. A matrix display portion and a matrix optical sensor portion are formed over one substrate. In addition, a driver circuit of the display portion and a driver circuit of the optical sensor portion formed over the same substrate as that for the display portion are built in one chip, whereby the number of components can be reduced. When the optical sensor is formed in a display panel, a barcode reader function or a scanner function can be given to the display panel. Furthermore, a function of authenticating fingerprints or the like or an input/output function of a touch sensor can be given to the display panel.

    Abstract: A display device that achieves both high-accuracy sensing by a touch sensor unit and smooth input using the touch sensor unit is provided. The display device includes a display unit and the touch sensor unit. The touch sensor unit performs touch sensing operation at a different timing from display image rewriting by the display unit, whereby the high-accuracy sensing can be achieved. The display unit has a function of rewriting a display image only in a region that needs to be rewritten. In the case where the entire display region is not necessarily rewritten, the time for the sensing operation by the touch sensor unit can be lengthened, whereby the smooth input can be achieved.
