摘要： An LCD imaging device, adapted as a visual display projector, is illuminated by a planar array of light emitting diodes (12) whose wavelength excites a phosphor layer disposed in close proximity with the LCD. A respective miniature lens (13) collimates light emitted from each chip in a forward direction, which collectively act to produce a uniform light field having rays confined within a prescribed angular range. An LCD imaging device (14), placed in the light field, spatially modulates the light field before its rays strike the phosphor layer, which fluoresces in response to the light.

摘要： The present invention relates to devices for displaying information and more precisely to liquid crystal displays (LCD), wherein said invention may be used in indication systems for various purposes as well as in optical modulators, light-modulation matrix systems, etc. The liquid crystal display of the present invention comprises a liquid crystal layer which is located between a front and a rear plate each bearing an electrode and a polariser. The display also comprises a dye-containing layer that includes a dye which is luminescent under the action of UV radiation at a wavelength of between 400 and 700 nm or a mixture of a luminescent dye and an absorbing dye. This invention provides better brightness and colour saturation of the image as well as a greater angle of vision of the LCD display as far as 180° thanks to the more efficient use of the radiation spectrum from a radiation source, particularly in the ultraviolet range.

摘要： The invention belongs to display units, in particular, to liquid crystal (LC) displays, and can be used in display/indicator equipment of various purposes, as well as in optical modulators, matrix systems for light modulation, etc. A liquid crystal display is proposed containing a layer of liquid crystal placed between the front and the back plates, with one electrode and one polarizer located on each of the plates, and a layer containing a dye. As the latter dye, either a single dye emitting luminescence under action of UV radiation in the range of 400-700 nm, or a mixture of one dye emitting luminescence and one absorbing dye, is used. The purpose of the invention is to achieve greater brightness and color saturation of the image, and to increase the viewing angle of LC displays up to 180° by more effectively utilizing the emission spectrum of the radiation source, in particular, its ultra-violet band.

摘要： The PLLCD (photoluminescent LCD) principle is applied to a projection display. A source (11) of largely monochromatic, near-visible UV light directs excitation light through a liquid-crystal (or acousto-optic) modulator (15). The photo-luminescent materials (31) that emit visible light when struck by the excitation light are mounted on a screen (3) and the modulated excitation light is projected onto this screen by a projector (17) in order to form a visible image. The image is controlled by a feedback mechanism involving reflective spots (33) on the screen, a video camera (121) and a controller (23). Alternatively a scanning technique can be used. Since only monochromatic light is required for the projection the system can be considerably simpler than RGB projection displays.
摘要翻译： PLLCD（光致发光LCD）原理应用于投影显示器。主要单色的，近可见的UV光源（11）将激发光引导通过液晶（或声光）调制器（15）。当被激发光照射时发射可见光的光致发光材料（31）被安装在屏幕（3）上，并且调制后的激发光被投影仪（17）投影到该屏幕上以形成可见图像。图像由涉及屏幕上的反射点（33），摄像机（121）和控制器（23）的反馈机构控制。或者可以使用扫描技术。由于投影只需要单色光，所以系统可以比RGB投影显示器简单得多。

摘要： A display device includes a shutter layer of liquid-crystal material arranged in cells to shutter input light selectively, a cover layer (5) on the shutter layer, and a set of phosphors (7) on the cover layer, corresponding to the cells, to be activated by the input light and provide the display image. To prevent crosstalk the active cell areas (10) defined by the electrode overlaps are smaller than the corresponding phosphors. This prevents crosstalk between cells even when input light that is not fully collimated is used and also allows space for thicker and/or broader electrodes (12) leading to the cells, reducing resistance, and for other components such as TFTs.

摘要： A reflection type liquid crystal display device according to the present invention is constructed to include: a light modulation layer having a light scattering state changed when a voltage is applied between electrode faces; at least one kind of color separation layer arranged at the back of the liquid crystal; and a reflection layer arranged at the back of the color separation layer. The light modulation layer is a polymer network type polymer scattered liquid crystal layer or a phase conversion type liquid crystal layer, and the color separation mirror is a cholesteric liquid crystal polymer layer or a dielectric multi-layered thin film characterised to reflect a light within a predetermined wavelength range in the visible light region selectively. A reflection preventing layer and an ultraviolet ray cut-off layer are further arranged on the surfaces of the electrode faces.
