    • Methods and apparatus are provided for a combined image on a head-up display. A data image display provides a first part of a combined image. An optical input provides a second part of the combined image, e.g., the background scene. A combiner superimposes the first and second parts to provide the combined image to the viewer. The data image display preferentially delivers s-polarized light to the combiner, which has a selective reflectance region for preferentially reflecting s-polarized light in a wavelength region of interest. In a preferred embodiment, the data image display comprises a backlight, a liquid crystal layer and two polarizers oriented so that the data images directed toward the combiner are s-polarized with respect to the selective reflectance region. A polarization rotation element may also be used in the data image display to facilitate s-polarization orientation.
    • 为平视显示器上的组合图像提供方法和装置。 数据图像显示提供组合图像的第一部分。 光学输入提供组合图像的第二部分,例如背景场景。 组合器叠加第一和第二部分以向观看者提供组合的图像。 数据图像显示优先将s偏振光传递到组合器,组合器具有用于优先反射感兴趣的波长区域中的s偏振光的选择性反射区域。 在优选实施例中,数据图像显示器包括背光源,液晶层和定向的两个偏振器,使得朝向组合器的数据图像相对于选择性反射率区域是s偏振的。 在数据图像显示器中也可以使用偏振旋转元件以便于s偏振取向。

    • Method and apparatus are provided for displaying an image to a viewer with reduced visual artifacts. The apparatus comprises a display panel for forming the image using an array of pixels with distributed active regions, and a viewing arrangement optically situated between the display panel and the viewer for transferring the image formed on the display panel to the viewer with limited angular pixel subtense. The distributed active regions of the pixels are desirably divided into at least two simultaneously switched portions at least partly separated by or surrounding a significant portion of the non-switchable region. First order spatial harmonics and associated artifacts are reduced by the distributed apertures and second order and higher harmonics are reduced by limiting the pixel subtense angle seen by the viewer. A significant reduction in visual artifacts arising from the periodic structure of the display panel is obtained.
    • 提供了一种方法和装置,用于以减少的视觉瑕疵向观看者显示图像。 该装置包括用于使用具有分布式有源区域的像素阵列形成图像的显示面板,以及光学地位于显示面板和观看者之间的观看布置器,用于将形成在显示面板上的图像以有限的角度像素折射 。 像素的分布式有源区域希望被分成至少两个同时切换的部分,至少部分地与不可切换区域的显着部分分开或围绕。 第一阶空间谐波和相关的伪影通过分布式孔径和二阶降低,并且通过限制观察者所看到的像素底角来减小高次谐波。 获得由显示面板的周期性结构引起的视觉伪影的显着减少。

    • An electronic dimming system for use in projection displays is provided. In a first embodiment, the dimming system comprises a first non-absorbing polarizer, a variable polarization rotator, a second non-absorbing polarizer and a heat absorber. The first non-absorbing polarizer receives light from a light source and passes the light of a selected polarization to the variable polarization rotator. The variable polarization rotator selectively rotates the polarization of the received light. The light passes from the variable polarization rotator to the second non-absorbing polarizer. The second non-absorbing polarizer passes only light of a second selected polarization. The light that passes the second non-absorbing polarizer is passed to the display, where it is used to illuminate the display. The system provides the ability to control the amount of light passed to the display by selectively rotating the polarization of the light with the variable polarization rotator.

    • A screen assembly that combines an angle re-distributing prescreen with a conventional diffusion screen is disclosed. The prescreen minimizes or eliminates the sensitivity of the screen assembly to projector location. The diffusion screen provides other desirable screen characteristics. The prescreen is preferably formed by a collection of light transmitting and refracting elements, preferably spheres 80, partially embedded in a light blocking layer. Toward the back of the spheres 80 are effective apertures 82 where the light blocking layer 81 is absent or at least thinner than in other regions toward the side of the spheres. The projected image enters spheres 80 through the effective apertures 82, and exits the spheres 80 centered orientationally about the normal to the lens axis. The re-oriented light rays then enter the diffusion screen for viewing.

    • Methods and apparatus are provided for color correction and contrast enhancement of projection displays. A visual display system includes a projector having a light source with a fixed spectral output, a display screen receiving the output of the projector and emitting a diffused output, and a color correction contrast enhancement filter positioned between the diffusing screen and a viewer. The filter differentially attenuates primary colors of the emission from the diffusing screen. The method includes projecting a light output from a light source having a fixed spectral output onto a diffusing screen, and attenuating primary colors of the emission from the diffusing screen with a light filter positioned adjacent to the diffusing screen.
