Head-up display glass and a head-up display system are provided. The head-up display glass includes laminated glass and a reflective coating. The laminated glass includes outer glass, a polymer interlayer, and inner glass. The reflective coating includes an inner barrier layer, an improvement layer, and at least one laminated structure that are stacked. The at least one laminated structure each includes a high refractive-index layer and a low refractive-index layer that are stacked in sequence in a direction away from the inner barrier layer. The high refractive-index layer has a refractive index greater than or equal to 1.8. The low refractive-index layer has a refractive index less than 1.7. The improvement layer is disposed between the inner barrier layer and the at least one laminated structure, or between the high refractive-index layer and the low refractive-index layer.

A display device includes an image display element, a collimator, a first light guide formed of a flat plate transparent to light, a second light guide formed of a plate member transparent to the light and having one surface that is a flat surface in contact with one of surfaces of the first light guide and the other surface that is a sawtooth surface, and a beam splitter formed on an interface between the first and second light guides to transmit a part of the light and reflect the remainder thereof. The sawtooth surface is configured by alternately combining a first surface non-parallel to a propagating direction of the light propagating through the second light guide after passing through the interface and configured to transmit the light and a second surface substantially parallel to the propagating direction.

Provided is a head-up display apparatus capable of preventing damage due to sunlight and ensuring user convenience. A reflection mirror M1 reflects an image created by a display panel and projects it onto a display region. A solar radiation sensor detects a sunlight intensity when a position of sun exists within a predetermined detection range. A blocking mechanism forms a projected light path of an image between the display region and the display panel when being turned off, and blocks the projected light path of the image and an incident light path of the sunlight which is direction opposite thereto when being turned on. A protection processor controls ON/OFF of the blocking mechanism based on an estimated temperature of the display panel, which is estimated by using a sunlight intensity from the solar radiation sensor, luminance of a light source, and an ambient temperature.

Discussed is a head-up display including a housing having an inner space, an imaging device in the inner space and to emit a first linearly polarized light in a first direction; an inner mirror spaced apart from the imaging device in the inner space and to reflect the first linearly polarized light emitted from the imaging device in the first direction; a polarization film to transmit the first linearly polarized light reflected from the inner mirror and reflect a second linearly polarized light in a second direction orthogonal to the first direction; and a phase delay mirror disposed outside the inner space and to phase-convert the first linearly polarized light transmitted through the polarization film after being reflected from the inner mirror into the second linearly polarized light so as to emit the second linearly polarized light to the polarization film.

Provided is a mirror unit capable of maintaining good vibration proof. A mirror unit comprises a reflecting mirror, and a holder that holds the reflecting mirror from a back surface thereof. The mirror unit rotates about an axis by the holder being pressed by a linearly moving slider, and is provided in a head-up display device. The holder comprises a part to be pressed, a first support part, and a second support part. The part to be pressed is located at a position that deviates from a center of the reflecting mirror toward a first end of the reflecting mirror, and is pressed by the slider. The first support part is located at a position corresponding to the part to be pressed, and is affixed to the back surface. The second support part is located closer to a second end of the reflecting mirror than the first support part, has a larger outer shape than the first support part, and is affixed to the back surface.
