The first light-emitting element includes a first pixel electrode, a first organic layer, and a common electrode, and the second light-emitting element includes a second pixel electrode, a second organic layer, and the common electrode. In a top view of the substrate, the first light-emitting element includes a first side and a second side that is shorter than the first side.

A projection of the first direction onto the substrate is parallel to the first side, and a projection of the second direction onto the substrate is parallel to the second side. An angle formed by the first direction and a normal direction of a surface of the substrate is 70°, and an angle formed by the second direction and the normal direction of the surface of the substrate is 70°.

摘要： A display unit having a function of sensing light is provided. The display unit includes a first and second light-emitting devices, a light-receiving device, and a light-blocking layer. The first and second light-emitting devices emit a first color. The light enters the light-receiving device through a first opening of the light-blocking layer. In a top view, |a−b| of a difference between the shortest distance a from the first light-emitting device to the light-receiving device and the shortest distance b from the second light-emitting device to the light-receiving device is smaller than |c−d| of a difference between the shortest distance c from the first light-emitting device to the first opening and the shortest distance d from the second light-emitting device to the first opening. In the top view, c is shorter than d. Alternatively, a light-emitting and light-receiving device can be used.

摘要： A display apparatus capable of performing authentication in a short time is provided. The display apparatus includes a first display portion where first pixels are arranged in a matrix, a second display portion where second pixels are arranged in a matrix, first and second row driver circuits, and a control circuit. Each of the first and the second pixels includes a light-receiving element. The first and the second pixels each have a function of acquiring imaging data by using the light-receiving element. The first and the second row driver circuits each have a function of selecting the first and the second pixels which read out the imaging data. The control circuit has a function of sequentially driving the first and the second row driver circuits in a first mode, and has a function of driving one of the first and the second row driver circuits on the basis of the imaging data in the second mode. Each of the scan rates of the first and the second row driver circuits in the first mode is higher than the scan rate of the first or the second row driver circuit in the second mode.

摘要： The cost of hardware and the cost of calculation are reduced in the case where a plurality of assembled batteries are used. The amount of change in the voltage of each battery constituting an assembled battery is sequentially measured with a voltage monitor and abnormality is detected from the correlation between the amounts of changes in the voltages of batteries at the same period. Furthermore, abnormality is detected on the basis of the amounts of changes up to the previous step. Inference is made by a reference parameter acquisition system using an IIR filter or an FIR filter.
