Description

  The present invention relates to a display device mounted on a mobile device such as an automobile or an aircraft, and a mobile device mounted with the display device.

  For example, in mobile devices such as automobiles and airplanes, a rear seat display device is embedded in the upper back side of the front seat. In this way, on the upper back side of the front seat, When a seating device is embedded, the orientation of the display device cannot be changed greatly.

  Therefore, it is conceivable that the display device is attached to the back side of the front seat using the attachment shaft.

  However, if the display device is mounted in an exposed state in this way, the exposed display device may be dangled or dangled by, for example, a child. Therefore, in order to increase the strength of the display device, And the cover that covers the back side must be made of a strong metal case.

  However, if the cover is made of a strong metal case, the weight becomes heavy, and in a mobile device such as an automobile or an aircraft, it is not preferable in view of safety at a sudden stop.

  Therefore, it is conceivable that the cover is made of carbon fiber reinforced plastic (Carbon Fiber Reinforced Plastics).
