Provided is a display device capable of adequately displaying in accordance with a condition. In a HUD device including a projector projecting an image that is to be a virtual image, a screen to which an image from the projector is projected, a magnifying optic magnifying the image projected on the screen, the screen is moved by an actuator in a direction parallel to an optical axis of the projector.

A head-up display system and a vehicle system are provided. The head-up display system includes a display and a projection screen. The display is configured to display a first image. The projection screen is disposed adjacent to the display and is configured to let the first image to be projected thereon to form a second image. The display includes a first region adjacent to the projection screen and a second region away from the projection screen. The projection screen includes a third region adjacent to the display and a fourth region away from the display. When the display displays the first image, a brightness difference between the first region and the second region is greater than a brightness difference between the third region and the fourth region.

Provided is a headup display device which is not liable to generate abnormal sound. The headup display device comprises: a liquid crystal display for emitting display light; a concave mirror for reflecting the display light; and a motor device for rotating the concave mirror. The motor device includes: a motor having a motor shaft projecting from a motor body; a worm connected to the motor shaft and having a spiral groove formed on the outer peripheral surface; and a worm wheel provided with teeth engaging with the spiral groove and transmitting a driving force from the motor to the concave mirror. A hole is formed inside the worm extending in the axial direction of the worm from the end face of the worm near the motor body. A compression coil spring is arranged in the hole for biasing the worm in the direction opposite the motor body and biasing the motor shaft toward the motor body.

According to an aspect, a display module includes a display panel that displays an image on a display surface; an optical member; and a housing that supports the display panel and the optical member. The housing includes a first housing, a second housing, and a third housing that is arranged on a side of the second housing opposite to the first housing side. An end of the first housing on a display surface side of the display panel protrudes toward the center of the display surface to face an outer edge of the display surface. An end of the second housing on a side opposite to the display surface side of the display panel protrudes toward the center of the display surface to face an outer edge of a surface opposite to the display surface. The optical member is provided between the second housing and the third housing.

A vehicle safety support system is provided. The vehicle safety support system according to some embodiments of the present disclosure can track and display the location of the object related to the vehicle, thereby assisting objects surrounding the vehicle to recognize the object related to the vehicle. Accordingly, it is possible to support the object related to the vehicle to safely get on and off the vehicle. Further, the vehicle safety support system according to some embodiments of the present disclosure can support the objects around the vehicle to perform safe passage or safe driving by providing various types of information related to the vehicle through an external display.
