摘要： Disclosed are a system and method for microprojection that uses multiple imagers to produce a high resolution output image. Each of a set of imagers produces a portion of the final image. Relay lenses then tile the individual image portions together into a combined image. Because the height of the individual imagers is smaller than the height of a monolithic imager, they can fit into a very thin device. The combined image has a resolution equal to the sum of the resolutions of the individual imagers. The individual images are tiled together within the microprojector itself rather than on a projection screen. This allows the tiling to be adjusted once at the factory and set forever. In some embodiments, the light created for use by the microprojector is split by a polarizing beamsplitter. Each resultant polarized beam is then sent to an imager. Another polarizing beamsplitter combines the individual images.

摘要： Disclosed are a system and method for microprojection that uses a “reduced-height” imager to sequentially display a series of partial images within one frame time. The partial images visually combine on a projection surface (e.g., a screen or a wall) into one high-resolution projected image. As a result, the microprojector projects an image with a resolution equal to the sum of the resolutions of the individual partial images while avoiding the use of very small imager optics with their lowered efficiency. For example, one embodiment projects exactly two partial images during each frame. During a first state of operation, a “half-height” imager displays the odd-numbered lines of the projected image. During a second state of operation, the imager displays the even-numbered lines of the projected image. By quickly cycling through these two states, no image flickering between phases is visible, and the combined image appears as a seamless whole.
摘要翻译：公开了一种使用“降低高度”成像器在一帧时间内顺序显示一系列部分图像的微喷射系统和方法。部分图像在投影表面（例如，屏幕或墙壁）上可视地组合成一个高分辨率投影图像。结果，微型投影仪以等于各个部分图像的分辨率的总和的分辨率来投影图像，同时避免使用非常小的成像器光学器件，其效率降低。例如，一个实施例在每个帧期间准确地投影两个部分图像。在第一操作状态下，“半高”成像器显示投影图像的奇数行。在第二种操作状态下，成像器显示投影图像的偶数行。通过快速循环通过这两个状态，阶段之间没有可见的图像闪烁，并且组合的图像显示为无缝整体。

摘要： A method and apparatus for controlling light intensity from two or more light sources. A timing scheme is used to modulate the light sources. Light from the light sources is combined to form a beam and a photo-sensor senses the beam. In a time interval when only one of the light sources is activated, the signal from the photo-sensor is monitored and used in a feedback control circuit to control the active light source.

摘要： A laser image projector display system (200) includes laser operating electronics (208, 210, 212, 400, 500, 700) that selectively operates a laser diode at a bias that is low enough to save energy based on analysis pixel brightness values. The laser bias may be high enough that laser can be transitioned to a lasing state in time to display a pixel, or the system can “look ahead” into a stream of pixels and adjust the bias in advance.

摘要： Disclosed are a system and method for microprojection that uses multiple imagers to produce a high resolution output image. Light created for use by the microprojector is split by a polarization-sensitive element into a number of beams. Each polarized beam is then sent to an imager. Each imager modulates the light beam to produce a portion of the final image. Another polarization-sensitive element directs the individual image portions through a projection lens system so that when they are projected, the individual image portions tile together into a seamless projected image. This technique uses essentially all of the original light, doubling the lighting efficiency of previous devices. Because the height of the individual imagers is smaller than the height of a monolithic imager, they can fit into a very thin device. The combined image has a resolution equal to the sum of the resolutions of the individual imagers.
摘要翻译：公开了一种用于微喷射的系统和方法，其使用多个成像器来产生高分辨率输出图像。由微型喷射器使用的光被偏振敏感元件分割成多个光束。然后将每个偏振光束发送到成像器。每个成像器调制光束以产生最终图像的一部分。另一个偏振敏感元件通过投影透镜系统引导各个图像部分，使得当它们被投影时，各个图像部分瓦楞在一起成为无缝的投影图像。这种技术基本上使用所有的原始光，使以前的设备的照明效率提高了一倍。因为单个成像器的高度小于单片成像器的高度，所以它们可以适合于非常薄的器件。组合图像的分辨率等于各个成像器的分辨率的总和。

摘要： Disclosed are image expanding lenses, display devices, and electronic devices incorporating the disclosed image expanding lenses. In accordance with a disclosed image expanding lens, the image viewed by the user is larger than the active area of the LCD panel underneath the lens, so that the border around, for example, the LCD display is hidden from viewing. The image expanding lenses may include a non-uniform transparent substrate, having for example, a wedge shape that may be the top surface of the display. The substrate in combination with prismatic films may bend the light output from an array of pixels so that the image hides the border of the display device. In this way, an electronic device can render an edgeless image to a viewer since the image of the electronic device is projected beyond an edge of the display device of the host electronic device.

摘要： A video projector includes a reduced size spatial light modulator (400) that spatially modulates light from a light source (502) according to only a portion (e.g., ½) of a video frame at a time. A beam steerer (508, 600, 1600) steers spatially modulated light from the spatial light modulator to a correspond region (e.g., upper half, lower half) of a projection screen/surface (512) and one or more lenses (506, 510, 702, 802, 1002, 1008, 1100, 1300, 1502) insure that the spatially light modulator (400) is imaged onto the projection screen/surface (512).
