An electronic device includes a device body and a stand supporting the device body. The stand includes: a base; a suction member facing the lower surface of base, including a suction surface that adheres to the placement surface by negative pressure generated in a gap between the placement surface and the suction surface, and including a ventilation hole in fluid communication with the gap; and a slide valve, located between the base and the suction member, that slides along the lower surface of the base between opened and closed positions where the ventilation hole is opened and closed to let and interrupt air into the gap, respectively.

The present invention relates to a multi-vision having a daisy chain type, capable of automatically setting an ID of each multi-vision set in a multi-vision where a plurality of sets are connected to each other in a daisy chain form, and an ID allocating method thereof. The multi-vision having a daisy chain type includes: a plurality of multi-vision sets; a first off switch provided at an IR communication line output port of each of the multi-vision sets, and configured to block an IR signal applied to each multi-vision set; series communication lines connected to the plurality of multi-vision sets in a bypass form; a second off switch provided at an output port of the series communication line of each multi-vision set, and configured to block an ID value which is to be bypassed to a next multi-vision set through the series communication line; and a controller configured to set an ID of a reference multi-vision set by blocking the first and second off switches, and configured to transmit an ID increased value to a next multi-vision set by releasing the blocked output state of the second off switch from the reference multi-vision set.

A lighting device includes LEDs 17, a light guide plate 19 including an edge surface and a pair of plate surfaces, a light reflection sheet 40, and a wavelength conversion sheet 50. A part of the edge surface is a light entrance surface 19B through which light from the LEDs 17 enters, and the pair of plate surfaces are light exit surfaces 19A, 19C through which the light exits. The light guide plate 19 includes second prism portions 65 formed on the light exit surface 19A and configured to collect light in a direction of a normal line of the light exit surface 19A. The light reflection sheet 40 is disposed to cover the light exit surface 19C reflects the light in a direction toward the light guide plate 19. The wavelength conversion sheet 50 is disposed between the light guide plate 19 and the light reflection sheet 40 and converts a wavelength of light transmitting therethrough.

A display control device that displays a video image taken by a camera on a display is disclosed. The display control device disposed in a vehicle, includes a housing configured to house a display on which a video image of surroundings of the vehicle taken by a camera is displayed, and to be able to be displaced independently of the display, a sensor configured to detect a displacement of the housing, and a control unit configured to perform control so that a video image shifted in a direction conforming to a direction of the displacement of the housing detected by the sensor is displayed.
