Assembly for the display of at least one piece of information for a portable object, this display assembly (1) including a first, at least partially transparent, display device (2) which is located on the side of an observer (4) and arranged to display at least a first piece of information, a second, at least partially transparent, display device (6) for displaying at least a second piece of information and a solar cell (10) being disposed in that order underneath the first display device (2), the first and second display devices (2, 6) being capable of switching between an active state in which they display information and a passive state in which they do not display information.

The invention relates to the display technology field, and particularly to a wire grid polarizer, a manufacturing method thereof, a display panel and a display device. The wire grid polarizer comprises a substrate, in which wire grid structures are arranged at intervals in an array, to allow light to penetrate from the grid pitches thereof, with the other area except the wire grid structures of the substrate being a continuous opaque area. Due to the wire grid polarizer being provided with the wire grid structures arranged at intervals in a array, local light transmitting areas can be formed, and light emergence can be controlled more flexibly. A display panel using the wire grid polarizer can effectively lower the light absorption rate, also avoid peripheral light leakage in a non-subpixel area, and prevent the light leakage of the pixels themselves; correspondingly, a display device using the display panel can improve the light utilization rate, and achieve a good display effect.

A LCD includes a liquid crystal panel, a backlight module opposite to the liquid crystal panel, at least one quantum rod film and at least one wavelength film. The quantum rod film is between the liquid crystal panel and the backlight module, and the wavelength film is between the quantum rod film and the liquid crystal panel. Light beams generated by the backlight module pass through the quantum rod film and the wavelength film in sequence to arrive the liquid crystal panel. By adopting the quantum rod film, the saturation of the LCD may be greatly enhanced.

A liquid crystal display comprises a backlight module comprising a reflective polarizing film, a light control film and a liquid crystal panel disposed between the backlight module and the light control film. The light control film comprises a light input surface and a light output surface opposite the light input surface and alternating transmissive and absorptive regions disposed between the light input surface and the light output surface. The absorptive regions have an aspect ratio of at least 30.

Provided is an image display device with a see-through type display capable of inhibiting the reduction of the visibility of a background seen through a screen due to light emission from bright spots resulting from scratches and stains on a light guiding plate. In this image display device, a liquid crystal panel 30, a light guiding plate 45 with a light source 40 attached thereto, and a transparent plate 20 are disposed, from the display surface (front) side to the rear side, so as to be parallel to one another, and therefore, the surface of the light guiding plate 45 is inhibited from being scratched or stained by the transparent plate 20. Thus, the visibility of the image display device 100 is prevented from being reduced by bright spots.

Ghost image formation due to reflections of image light by a display panel to an ocular lens may be suppressed by ensuring that the image light reflected by the lens does not get reflected by the display panel back towards the lens. To that end, the display panel may include a quarter-wave birefringent layer between the top polarizer of the display panel and a layer inside the display panel that the image light reflects from, such as a black grid layer or an active matrix layer.

An optical lens assembly and a head-mounted display (HMD) is provided. The optical lens assembly includes a first optical element including a partial reflector and a quarter-wave plate, a second optical element including a reflective polarizer, and a varifocal lens disposed inside a cavity formed by the first optical element and the second optical element. The varifocal lens is a liquid crystal (LC) lens stack including a plurality of LC lenses. An LC lens of the plurality of the LC lenses has a plurality of optical states including an additive state that adds optical power to the varifocal lens and a subtractive state that removes optical power from the varifocal lens. The plurality of optical states provides a range of adjustment of optical power for the optical lens assembly.

A display comprises a polarised output spatial light modulator, switchable liquid crystal retarder, absorbing polarizer and touch panel electrodes. The switchable liquid crystal layer is stabilised by a cured reactive mesogen material during application of an applied voltage. Light scatter in privacy mode is reduced and visual security level enhanced. Visibility of disclinations during application of applied pressure, for example from a finger on a touch screen is minimised.

Provided are a light source unit, a display device, and a film. The light source unit has a light source and a film, the light source has a light-emitting band in the 450-650 nm wavelength range, the film has a mean transmittance of 70% or higher for light in the 450-650 nm wavelength range from the light source and incident at an angle of 0° to the normal to the film surface, the film satisfies the relationship Rp20≤Rp40<Rp70 with Rp70 being 30% or greater when Rp20, Rp40, and Rp70 represent the mean reflectance (%) for P waves in the 450-650 nm wavelength range for light from the light source incident at angles of 20°, 40°, and 70° to the normal to the film surface, and the light source and the film satisfy specific relationships.

A heads-up display includes a thin-film transistor (TFT) panel, along with at least one reflective polarizer subassembly. Each of the at least one reflective polarizer subassembly includes a clear substrate having opposing first and second surfaces. The first surface is connected to the TFT panel, and the second surface has a polarizing film laminated thereto. The first surface of the clear substrate is textured, frosted, or the like such that when it is attached to the TFT panel it inhibits bonding between the clear substrate and the TFT panel that would cause optical defects.
