摘要： A display includes a layer of NCPT liquid crystal material (1) capable of modulating both internal UV radiation (20) and ambient light (30) impinging on the device from the viewing side, in order to combine an emissive function with a reflective function. For emission the UV radiation is selectively applied to phosphors (11) on the viewing side, while for reflection the ambient light is selectively reflected by the liquid crystal. The two functions operate together as each display cell is switched between an 'off' state in which ambient light penetrates the display, being absorbed in a black background (25), while the input radiation is prevented from reaching the phosphors and hence from causing output, and an 'on' state in which the ambient light is scattered from the liquid-crystal layer (thus being visible in daylight) and the input radiation (20), likewise scattered, reaches the phosphor (11) and causes it to emit (thus being visible in the dark).

摘要： An image-forming device includes a source of radiation (20), e.g. UV, a means such as a liquid-crystal cell (1) for modulating this radiation according to the image to be formed, and an output means (11) towards which the modulated radiation is directed and whose reflective or absorptive properties are altered when it receives the radiation. A suitable material for the output means is a photochromic material which changes colour under the influence of UV. Such a display can be made easily visible in strong ambient light. The output means can also be made removable, the device then acting as a printer.

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： 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.
