摘要： This disclosure relates to the field of head-up display (HUD) technology, and more particularly to an HUD system with a transparent nano film for image display. Specifically, an HUD system including ultra-thin glass is provided in the disclosure. The HUD system includes a projection light source, and laminated glass, and a transparent nano film. The transparent nano film includes at least two metal layers. The projection light source is configured to generate P-polarized light. The laminated glass provided with the transparent nano film has a maximum reflectivity Rmax and a minimum reflectivity Rmin for the P-polarized light that has the incident angle ranging from 45° to 72°, where Rmax/Rmin ranges from 1.0 to 2.0.

摘要： An object is to provide an optical system capable of improving the brightness of a main image while eliminating a ghost image. In an optical system including: an image display device that emits an image; a linear polarizer through which light associated with the image passes; a first quarter wavelength plate which receives the light from the linear polarizer; a half mirror; a reflective polarizer; and a second quarter wavelength plate provided between the reflective polarizer and the half mirror, retardance of the first quarter wavelength plate and retardance of the second quarter wavelength plate are equal, and thus the object is achieved.

摘要： The optical system introduces light from a display element displaying an image to an observer. The optical system includes in order from the display element toward the observer, a first phase plate, a semi-transmissive reflective surface, a lens, a second phase plate, and a polarization beam splitter configured to reflect a first linearly polarized light and transmit a second linearly polarized light whose polarization direction is orthogonal to that of the first linearly polarized light. The semi-transmissive reflective surface has a transmittance smaller than a reflectance thereof.

摘要： An annular optical element includes an outer annular surface, an inner annular surface, a first side surface, a second side surface and a plurality of strip-shaped wedge structures. The outer annular surface surrounds a central axis of the annular optical element and includes at least two shrunk portions. The first side surface connects the outer annular surface and the inner annular surface. The second side surface connects the outer annular surface and the inner annular surface, wherein the second side surface is disposed correspondingly to the first side surface. The strip-shaped wedge structures are disposed on the inner annular surface, wherein each of the strip-shaped wedge structures is disposed along a direction from the first side surface towards the second side surface and includes an acute end and a tapered portion connecting the inner annular surface and the acute end.

摘要： A method operates a visual field display device, in particular for a motor vehicle, which is designed to produce a projection light beam with a display content and to project the display content onto a partially transparent reflecting projection screen, in particular a front window of the motor vehicle, such that a virtual display image which is superimposed into a field of vision of a user is generated behind it. The method determines image element edges having vertical or a vertical component in the virtual display image to be superimposed and tilts the image element edges thus determined to a respectively adapted tilt angle with respect to the vertical, such that double images of the respective image element edges in the virtual display image are offset with respect to each other in the horizontal direct for the user due to double reflections of the projection light beam on two optical boundaries of the projection screen and appear substantially sharp.

摘要： An annular light trapping component includes an inner surface, an outer surface, an object-side surface and an image-side surface. The inner surface includes multiple L-shaped annular grooves. The annular light trapping component includes multiple stripe-shaped structures in the L-shaped annular grooves. The L-shaped annular grooves include an object-side L-shaped annular groove closest to the object-side surface and an image-side L-shaped annular groove closest to the image-side surface. A bottom diameter of the image-side L-shaped annular groove is larger than a bottom diameter of the object-side L-shaped annular groove. Each L-shaped annular groove includes a first side and a second side located between the object-side surface and the image-side surface. The stripe-shaped structures are disposed on the first side or the second side. A degree of inclination between the first side and the central axis is larger than a degree of inclination between the second side and the central axis.
