A display region has a curved surface shape having upper and lower end portions disposed at positions closer to a visual field than a reference plane, and a central portion disposed at a position farther from the visual field than the reference plane. A first convergence angle difference between a convergence angle from the eye position to the upper end portion and a convergence angle from the eye position to a first point on the reference plane through the upper end portion, a second convergence angle difference between a convergence angle to the central portion and a convergence angle to a second point on the reference plane through the central portion, and a third convergence angle difference between a convergence angle to the lower end portion and a convergence angle to a third point on the reference plane through the lower end portion respectively fall within four milliradians.

The present disclosure relates to an apparatus for controlling a multi-image display provided in a vehicle, and a method thereof. According to the present disclosure, a multi-image display device may simultaneously output two or more images separated depending on an output angle or an optical frequency, and a first reflection member provided in an indoor ceiling of the vehicle may reflect one image among the two or more images output from the multi-image display device.

The head-up display apparatus includes a display-light emitting unit having a second inclination angle around the axis parallel to the vertical direction so that the first direction side thereof is closer to the user than the second direction side thereof is, and being configured to emit display light forming a rectangular image corresponding to the rectangular virtual image. The head-up display apparatus includes a reflecting mirror having a third inclination angle around the axis parallel to the vertical direction so that the first direction side thereof is closer to the user than the second direction side thereof is, and being configured to reflect the display light and emit reflected light to the virtual-image display unit.

A mirror device includes: a mirror having a rotation shaft and a reflecting surface that reflects display light; a support portion having a cylindrical shape, having a base end fixed and a tip end being a free end, and configured to rotatably support the rotation shaft; and a motor that pivots the mirror, in which the rotation shaft is inserted into the support portion while spreading the support portion outward in a radial direction, and is slidably supported by the support portion.

A head-up display apparatus is disclosed. The head-up display apparatus according to one embodiment of the present invention comprises: a display panel; a stereoscopic image filter; and a mirror. The display panel includes a first region in which a first image is displayed and a second region in which a second image is displayed, and the stereoscopic image filter is configured to convert the first image into a stereoscopic image. In an embodiment of the present invention, the first image displayed on the display panel is warped and displayed, thereby preventing distortion of the stereoscopic image when projected on a windshield.

An anti-motion sickness device fitted to a motor vehicle including a triaxial accelerometer to detect the vehicle accelerations along three axes and to emit a corresponding acceleration signal; a display component of light markers to form at least one first and second artificial horizon lines at first and second inner surface, respectively of the motor vehicle. The device includes a control unit for receiving the acceleration signals and for driving the display wherein the artificial horizon lines are aligned in a horizontal plane perpendicular or substantially perpendicular to the gravity vector regardless of vehicle accelerations. The control unit is configured to process the acceleration signals, prior to the control of the display to determine in real time an acceleration frequency according to each of the accelerometer axes and to drive the display only when the acceleration frequency is below a threshold frequency, below which the motion sickness likely occurs.
