  • Patent number: 9348160
    Abstract: Display components (e.g., liquid crystal displays (LCDs)) are viewable at different viewing angles, for example, by a first user positioned directly in front of the display and by a second user positioned to one side of the display. Many displays present a consistent display across a wide range of viewing angles, but these displays may consume energy and/or compromise user privacy. Presented herein are configurations of backlights for display devices featuring an adjustable viewing angle, such that a user may select a narrower viewing angle in usage scenarios involving power consumption or privacy, and may select a wider viewing angle in usage scenarios involving plentiful power and fewer privacy concerns. Such configurations may include multiple banks of backlight lamps generating backlight at different viewing angles; an electrowetting electrode as an adjustable collimator; adjustable diffusers that may adjustably scatter light passing therethrough; and/or a combination of such adjustable elements.

    Abstract: A display including an image-generating panel and at least one contrast-enhancing panel, a cross BEF collimator between a backlight and one of the panels, and a polarization-preserving diffuser (e.g., holographic diffuser) between the panels. Typically, the contrast panel is upstream of the image panel, and a reflective polarizer is positioned between the cross BEF collimator or and contrast panel, with the reflective polarizer oriented relative to an initial polarizer of the contrast panel. Polarization of light transmitted by the reflective polarizer matches that transmitted by the initial polarizer. Collimated light propagating from the cross BEF collimator toward the contrast-enhancing panel is given a polarization bias by the reflective polarizer, which reflects incorrectly polarized light back toward the cross BEF collimator.

    Abstract: Disclosed is a display device, comprising: two liquid crystal cells connected together and facing in opposite directions, each liquid crystal cell includes a substrate, a pixel electrode, a common electrode, and a cholesteric liquid crystal layer filled between the pixel electrode and the common electrode, the polarization properties of the filled cholesteric liquid crystals are opposite to each other. In the present invention, the two cholesteric liquid crystal cells are connected together, such that transparent display as well as double-side display can be achieved by using the reflective, polarizing and full stable performance of the cholesteric liquid crystals as well as by controlling voltage to switch two cholesteric liquid crystal cells between a plane orientation and a vertical orientation. In addition, with this technology, no polarizer is used and light absorption is removed, thus, the transmission rate of the display device is improved.

  • Patent number: 9230462
    Abstract: To provide an image display device in which reflection of an image on one display surface onto another display surface is suppressed. In an image display device where an image is displayed on a screen combining the display surfaces of two or more image display elements, a polarizing plate is arranged on the display surface on conditions that extinction takes place between the display surfaces of the image display elements. The extinction conditions are set such that the light entering from a display surface to which the polarizing plate is fixed is passed through and the light entering from other than the above display surface is absorbed by intersecting the polarization directions of the polarizing plates perpendicularly.
