摘要:
3D stereoscopic viewing enabled by the use of a fast switching speed LCD panel, dynamic backlight, and low cost glasses. The system utilizes an LCD panel with an LED backlight and wavelength selective glasses to isolate each channel by color. The system is based on alternating left and right image frames on an LCD panel. The left and right frames are illuminated by two slightly different red-green-blue light sources that are synchronized sequentially. The light sources are designed to emit light of different spectral composition. The viewer wears glasses where the left lens or filter passes only the spectrum of light used for the left channel of data, and the right lens or filter passes only the spectrum of light used for the right channel of data.

摘要:
A backlight that includes a front reflector and a back reflector that form a hollow light recycling cavity including an output surface is disclosed. The backlight further includes one or more light sources disposed to emit light into the light recycling cavity. The front reflector includes an on-axis average reflectivity of at least 90% for visible light polarized in a first plane, and an on-axis average reflectivity of at least 25% but less than 90% for visible light polarized in a second plane perpendicular to the first plane.

An illumination device, such as a backlight for electronic display devices, is disclosed. The illumination device includes a viscoelastic lightguide optically coupled to a light source, and a nanovoided polymeric layer is used in conjunction with the lightguide to manage light emitted by the light source. The viscoelastic lightguide may be a pressure sensitive adhesive.
摘要:
Microreplicated light redirecting films suitable for use in autostereoscopic displays and backlights are made to incorporate at least one nanovoided layer whose interface with another layer forms an embedded structured surface of the light redirecting film. The nanovoided layer includes a polymer binder and optional nanoparticles, and may have a refractive index less than 1.35 or 1.3. The light redirecting films may be adapted for attachment to one or more other components of an autostereoscopic display, such as a display panel and/or a light guide of a backlight.

摘要:
A display apparatus includes an autosteroscopic liquid crystal display panel having a frame response time of less than 10 milliseconds, and a backlight positioned to provide light to the autosteroscopic liquid crystal display. The backlight includes a right eye solid state light source and a left eye solid state light source capable of being modulated between the right eye solid state light source and a left eye solid state light source at a rate of at least 90 Hertz.
