摘要： A display device comprising a plurality of pixels (26), a light source (23), and addressing means (24, 25) for coupling a selected pixel to said light source to thereby emit light, wherein the addressing means (24, 25) are arranged to address each pixel using pulse-width modulation (PWM). Further, the display comprises means (20) for amplitude modulating the intensity of said light source (23). The combination of the two modulations generates an exponentially distributed emitted light intensity, enabling proper gray scale rendering for a limited resolution in the time domain.

摘要： A projection system is described for displaying image information, comprising an illumination system for generating a light beam, a scanning device comprising a mirror for scanning the generated light beam to form an image on a screen, and a scan angle enlarger cooperating with the scanning device for enlarging a scan angle of the generated light beam. The scan angle enlarger comprises a reflective polarizer, a quarter-wave plate and a mirror arranged to reflect the light beam at least once between the reflective polarizer and the mirror via the quarter-wave plate. This arrangement allows a compact assembly of the projection system for use in small portable devices such as mobile phones and PDAs.

摘要： The present invention relates to a light valve (40) for reflecting and diffracting incident light, comprising an electrostatically operable foil (42) provided with a reflective surface (60), a reflective grating structure (52) provided on one side of the foil (42), and means (48, 56, 60) for inducing electrostatic forces on the foil (42) for switching it between a first position, in which the foil is separated from said grating structure (52), whereby incident light (64) received by said light valve (40) will be diffracted by said reflective grating structure (52), and a second position, in which the foil is brought into contact with said grating structure (52), whereby incident light (64) received by said light valve (40) will be essentially specularly reflected by said foil electrode (60). A grating structure having no movable parts may thus be used, which makes the light valve easy to manufacture. The invention also relates to an imaging system comprising at least one such light valve.

摘要： A projection device, comprising means (4a, 4b, 5, 6) for directing a plurality of light beams (3a, 3b, 3c) onto a scanning device (13), adapted to scan said beams in order to project an image on a surface. The device has an adjustable lens arranged in the optical path of said beams after said scanner so that the scanner is located between the lens and its focal length. Through this arrangement, the adjustable lens will enable a reduction of the angular spread of the projection, without reducing the resolution of the displayed image. This, in turn, enables a projection of an image at a desired distance, while such a size is maintained that the available light intensity is sufficient.
摘要翻译：一种投影装置，包括用于将多个光束（3a，3b，3c）引导到扫描装置（13）上的装置（4a，4b，5,6），适于扫描所述光束以便在表面上投影图像。该装置具有布置在所述扫描器之后的所述光束的光路中的可调节透镜，使得扫描仪位于透镜和其焦距之间。通过这种布置，可调透镜将能够减小投影的角度扩展，而不会降低显示图像的分辨率。这又可以使图像以期望的距离投射，而这样的尺寸被保持为可用的光强度足够。

摘要： The invention relates to a light pen input system with a light pen which is adapted to generate at least one scanning light line sweep for scanning a surface such as for example a display screen. The time from starting a scan until a light sensing element placed at a known position detects a scanning light line is measured and processed for determining the coordinates of the pointing position of the light pen. Thus, an “inverse” light pen is provided which may be implemented at low costs and which may be used with non-CRT displays. Furthermore, the system is independent of the display screen size.
