    摘要： A multi-view autostereoscopic display device comprises: a backlight having a plurality of backlight areas arranged in a width direction of the display device; a spatial light modulator arranged over and in registration with the backlight, the spatial light modulator having an array of display forming elements arranged in rows and columns for modulating light received from the backlight; and a view forming layer arranged over and in registration with the spatial light modulator, the view forming layer having a plurality of view forming elements arranged in the width direction of the display device, each view forming element being configured to focus modulated light from adjacent groups of the display forming elements into a plurality of views for projection towards a user in different directions. The backlight is switchable to activate different ones of the backlight areas in different portions of a driving cycle of the display device so that, in the different portions of the driving cycle, modulated light from the active backlight areas is incident on each view forming element with respective different angles of incidence. In this way, the overall viewing angle or the effective three dimensional display resolution may be increased.

    摘要： An optical system that can add an optical depth information to a two-dimensional image (72) represented by substantially collimated light, e.g. by using a collimated light source in front of a LCD display. The optical system includes a first array of optical lenses (70) arranged at a first distance in front of the two-dimensional image (72), and a second array of optical lenses (71) arranged at a second distance in front of the two-dimensional image (72), the second distance being larger than the first distance. Optical properties, e.g. focal length, can be adjusted for the optical lenses of the first and second array of optical lenses (70, 71) in response to the optical depth information. The optical system can serve as an optical front for 3D multiview displays. Depending on embodiment, both horizontal and vertical angular resolution can be obtained, and the front end exhibits only a small brightness loss. Preferably one lens per pixel is used in case of a pixelized image. In one embodiment, a stack of several arrays of on/off switchable optical lenses are arranged at different distances in front of the two-dimensional image, wherein a depth is applied by turning on one lens corresponding to the desired depth distance. In another preferred embodiment two arrays of continuously adjustable lenses are used to generate a depth by adjusting the lenses so as to provide an apparent position in between the two arrays. Preferably, a diffuser is positioned in front of the second array of lenses. Different shapes of lenses may be used such as spherical lenses, lenticular lenses, Fresnel type lenses or “horse-saddle” shaped lenses. The arrays of lenses may be implemented using GRIN lenses or fluid-focus lenses. Preferably, the lenses of each array of lenses are individually adjustable.

    摘要： A method and apparatus for increasing the brightness of a color-sequential matrix display, in which the matrix display is addressed on a line-by-line basis, includes dividing a frame period of said matrix display into sub-fields corresponding to the number of light colors being used to sequentially illuminate said matrix display illuminating the display sequentially with said light colors, each for the duration of the corresponding sub-field, and pre-processing the video signal to compensate for errors due to illuminating the display during the addressing time and LC response time. The pre-processing includes determining a direction and an amount of gray scale level change from a preceding sub-field to a current sub-field, and increasing or decreasing the video signal in the current sub-field in dependence on the determined direction of the gray scale level change from the preceding sub-field and by an amount corresponding to a predetermined factor of said determined amount of gray scale level change.

    摘要： A color cathode ray tube (CRT) has an electron-optical system (1) for generating three electron beams (EBR, EBG, EBB), deflection means (2) and a screen (3). In operation, the deflection means (2) deflect the electron beams (EBR, EBG, EBB), so as to change a landing position of the beams on the screen (3). However, by deflecting the beams, the beams are defocused and the spot on the screen (3) changes. In a color cathode ray tube with a relatively large screen, the electron beam defocusing can be observed to be different in strength for each beam (EBR, EBG, EBB). The invention provides a solution to this problem by providing a modified DAF section (40) in the electron-optical system (1). The DAF section (40) comprises at least two electron lenses (L1, L2) having different strengths for each electron beam (EBR, EBG, EBB).
