  • Patent number: 10871653
    Abstract: A system included in a wearable viewing device (10) prevents reduction in legibility of a near-eye image display for observation in combination with an observer's visual exterior view. The system includes a near-eye image source (14) from which emanates near-eye image-carrying light and which is positioned out of the observer's direct visual exterior view. A dimming matrix display (12) including multiple pixels is positioned so that the observer (22) can see though them a scene (30, 32) in an exterior view. A partly transparent optical element (20) is positioned so that the observer can see the scene in the exterior view and reflect the near-eye image-carrying light to provide an image for observation by the observer. A dimming controller (34) controls amounts of scene-carrying light propagating through the multiple pixels from the locations in the scene and thereby prevents wash-out of the near-eye image when outside illumination is very bright.

  • Patent number: 10859879
    Abstract: The present disclosure provides a liquid crystal grating, a method for driving the liquid crystal grating, and a display device. In the embodiments of the present disclosure, by applying the second voltage and the third voltage that are mutually inverted with respect to the common electrode voltage, the situation in which a single phase voltage is applied to all grating electrodes corresponding to the power-on optical state can be avoided. Due to the capacitance of liquid crystal, the influence of the second voltage on the common electrode voltage and the influence of the third voltage on the common electrode voltage cancel each other out. Therefore, the fluctuation of the common electrode voltage caused by the capacitance of liquid crystal can be effectively reduced or eliminated, thereby avoiding the failure of the liquid crystal grating.

  • Patent number: 10616564
    Abstract: A display device has a display panel (70) and a color filter layer (72) spaced from the display panel, comprising an array of color filter portions. In a privacy mode (narrow viewing angle mode), the display panel produces output regions of different light output color, which regions are aligned with corresponding color portions of the color filter layer. In a public mode (wide viewing angle mode) the display panel produces light containing all of the output colors to all of the output regions. By providing a color filter layer spaced from the display panel, color filtering is used to control the range of angles over which an image is output. The color filter layer is in essence moved away from the display panel. The spacing between the two and the width of the color filter portions determines the extent by which the light output is angularly limited.

    Abstract: A display panel and a method for fabricating the same are disclosed. The display panel includes a first substrate, a second substrate which is arranged oppositely to the first substrate, a frame sealant which is arranged between the first substrate and the second substrate, and a black matrix which is arranged on the second substrate. A projection of the black matrix on the first substrate does not overlap a projection of the frame sealant on the first substrate. This facilitates completely exposing the frame sealant to a curing UV light. This improves a curing efficiency of the frame sealant, increases the adhesiveness of the frame sealant, and avoids the problem of liquid crystal leakage due to breakage of the frame sealant.
