A double-sided display device includes a pair of substrates, on which self-emitting elements are formed respectively, being bonded to each other. The device can use a standard transport protocol such as PCI-E, SAS, SATA, eMMC, SCSI, and so on. The control circuit can be configured to control the energy emitter, to compare the first proximity information with second proximity information, and to modulate a delay between the first pulse of energy and a subsequent pulse of energy using the comparison. A further upper stowage space is covered by a second lid which is designed as a further part of the armrest and can be pivoted about a pivot axis.
