Abstract: To provide a support for supporting a flexible component and a light-emitting device. A first substrate, a second substrate, a rack, a pinion, and a hinge are provided. When the second substrate is moved, the rotational force of the pinion is transmitted to the rack of the first substrate and thus the first substrate is moved in the horizontal direction while being overlapped with one of hinge pieces of the hinge; accordingly, the flexible component can be bent while the flexible component is fixed to the first substrate and the second substrate and the allowable curvature radius is maintained in the vicinity of the hinge.

Abstract: A highly portable and highly browsable light-emitting device is provided. A light-emitting device that is less likely to be broken is provided. The light-emitting device has a strip-like region having high flexibility and a strip-like region having low flexibility that are arranged alternately. In the region having high flexibility, a light-emitting panel and a plurality of spacers overlap with each other. In the region having low flexibility, the light-emitting panel and a support overlap with each other. When the region having high flexibility is bent, the angle between normals of facing planes of the two adjacent spacers changes according to the bending of the light-emitting panel; thus, a neutral plane can be formed in the light-emitting panel or in the vicinity of the light-emitting panel.

Abstract: A novel functional panel, a novel device, or a novel data processor is provided. A structure in which a first plane, a second plane that is opposite the first plane, and a neutral plane between the first plane and the second plane are provided and a portion of a functional layer having a thickness greater than or equal to half of the thickness of the functional layer is in a region between the first plane and the neutral plane was conceived.

Abstract: Provided is an electronic device with high portability and/or high browsability. The electronic device includes first and second support bodies, a first hinge, and a flexible display panel. The first hinge has a first rotation axis and connects the first and second support bodies to each other, and the first and second support bodies are capable of relatively rotating on the first rotation axis. The display panel includes at least first and second portions supported by the first and second support bodies, respectively; the first rotation axis and a first plane including the display surface overlapping with the first portion or a second plane including the display surface overlapping with the second portion are parallel to each other; and each of a distance between the first rotation axis and the first plane or the second plane is greater than zero.

Abstract: A plurality of nodes are connected to one another so as to form a ring network. A pseudo master node blocks relay of user data on one side, and transmits in the ring network a health packet that contains information about a priority order in which the pseudo master node is to be set as a master node. If the pseudo master node receives the health packet transmitted by it, or receives a health packet transmitted by another node, the pseudo master node judges whether the pseudo master node is to be set as a master node based on the priority order contained in the received health packet.
