Abstract: An angle adjustment device capable of being kept at a desired angle is provided. The angle adjustment device can fix and keep the relative positions of the first base component and the second base component, and a support with a combination of the angle adjustment device and components such as a flat plate can keep the entire body in a shape opened on a plane, a folded shape, a shape kept at a desired angle, or the like. In addition, the angle adjustment device can make a bending movement in one direction, which prevents bending in a reverse direction. Therefore, it is possible to prevent an accidental bending movement of an apparatus including the angle adjustment device to prevent breakage or the like of the apparatus.

Abstract: When a base film used in a flexible display panel is bonded to a resin member for fixing the base film that is curved, the base film has creases by an environmental change such as temperature due to difference in linear expansion coefficient before and after a thermal shock. A buffer plate that is thin enough to be bent is provided between the base film used in a flexible display panel and the resin member. With the use of heat dissipation effect and heat equalization effect of the buffer plate, a structure around the panel capable of resisting the environmental change can be provided.

Abstract: Damage to a flexible display can be prevented. A display device having improved mechanical strength can be provided. A display device (10) includes a display panel (11) and a protection cover (12). The display panel (11) includes a first portion having flexibility. The protection cover (12) has a light-transmitting property and flexibility and is provided to overlap with a display surface side of the display panel (11). The display device (10) has a function of being reversibly changed in shape to a first mode in which the display panel (11) and the protection cover (12) are each substantially flat and a second mode in which the first portion of the display panel (11) is curved such that the display surface side becomes a concave surface and part of the protection cover (12) is curved in the same direction as the first portion. In the second mode, there is a gap between the first portion and the protection cover.

Abstract: Provided is a novel light adjustment program that can make a human feel at ease. Provided is the light adjustment program that includes the steps of obtaining basic data having 1/f fluctuation characteristics; generating first smoothed data and second smoothed data by performing moving average processing with different periods on the basic data having 1/f fluctuation characteristics; generating light adjustment data by subjecting the first smoothed data and the second smoothed data to arithmetic processing; and changing luminance of a light-emitting device in time series in accordance with the light adjustment data.

Abstract: A novel display panel that is highly convenient, useful, or reliable is provided. The display panel includes a display region, a first support, and a second support, the display region includes a first region, a second region, and a third region, the first region and the second region each have a belt-like shape extending in one direction, and the third region is sandwiched between the first region and the second region. The first support overlaps with the first region and is less likely to be warped than the third region, and the second support overlaps with the second region and is less likely to be warped than the third region. The second support can pivot on an axis extending in the one direction with respect to the first support.

Abstract: The power consumption of a control device or a data processing system is reduced. Safety is enhanced. An electronic device is operated in a simple way. A control device includes an arithmetic circuit, an input unit, and a power management unit. The input unit includes a sensor element. The power management unit has a function of controlling supply and shutdown of power to the arithmetic circuit. The power management unit has a function of supplying power to the arithmetic circuit in response to a detection signal output from the sensor element. The sensor element includes one or more selected from an acceleration sensor, an angular velocity sensor, and a magnetic sensor. The arithmetic circuit includes a register. The register includes a first circuit and a second circuit. The register has a function of storing, in the second circuit, first data stored in the first circuit in a period during which the power management unit supplies power to the arithmetic circuit and retaining the first data, in a period during which the power management unit stops power supply to the arithmetic circuit. The arithmetic circuit has a function of generating second data with use of signal data output from the sensor element and the first data.

Abstract: A plurality of display panels having a curved surface are placed in a limited space. Two, or three or more display panels are combined to form one display region having a T-shaped outer edge as one screen, and a driver can curve part of the display panel as appropriate so that the driver can see the screen easily. A first display panel or a second display panel has flexibility and includes a position adjustment function of curving an end portion. That is, by curving part of the display panel, the user can see the display panel easily. The in-car design can also be varied.
