    • A full color display is disclosed having a high efficiency light source optically coupled by a light coupling lens array to the active matrix of pixel elements of an image forming means such as a transmissive liquid crystal light valve. The light source is comprised of a patterned matrix of individual, primary colored visible radiation emitters, such as individual phosphor elements, arranged in a manner suitable for the human eye to integrate the individual primary colored lights into a single mixture color. The light coupling lens array collects substantially all of the light rays emitted from each primary colored light emitter and focuses them on a respective one of the transparent electrodes in the active matrix, as a real image smaller than the size of the electrode. A suitable light coupling lens array is a gradient index lens array, a multiple layer, two dimensional array of microlenses functionally analogous to an array of strip lenses, or a microlens array. A twisted nematic liquid crystal cell may be used in the image forming means to achieve a high contrast display. Use of the light coupling lens array to collect and focus the light rays from the light source permits the focused light to pass through an entrance polarizer with minimal scattering or divergence, and then through the respective transparent electrode in the active matrix unobscured by the opaque pixel interconnect elements. More efficient use of a larger percentage of the light from the light source in this manner results in the formation of a bright, high contrast, full color image.
    • 公开了一种全色显示器,其具有通过光耦合透镜阵列光耦合到诸如透射型液晶光阀的图像形成装置的像素元件的有源矩阵的高效光源。 光源包括单独的初级着色可见辐射发射器(例如单独的磷光体元件)的图案化矩阵,其以适于人眼的方式布置,以将单独的主要着色光整合为单一混合颜色。 光耦合透镜阵列基本上收集从每个主要着色光发射器发射的所有光线,并将其聚焦在有源矩阵中的相应一个透明电极上,作为小于电极尺寸的实像。 合适的光耦合透镜阵列是梯度折射率透镜阵列,多层,微透镜的二维阵列,功能上类似于带状透镜阵列,或微透镜阵列。 可以在图像形成装置中使用扭转向列型液晶单元,以实现高对比度显示。 使用光耦合透镜阵列来收集和聚焦来自光源的光线允许聚焦光以最小的散射或发散方式通过入射偏振器,然后通过由不透明像素遮挡的有源矩阵中的相应透明电极 互连元件。 以这种方式更有效地利用来自光源的更大百分比的光导致形成明亮的高对比度全色图像。
