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. 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： The invention provides a method for attaching a flip chip to an electrical substrate such as a printed wiring board. A bumped flip chip is provided, the flip chip including an active surface and a plurality of connective bumps extending from the active surface, each connective bump including a side region. A thin layer of an underfill material is applied to the active surface of the flip chip and to a portion of the side regions of the connective bumps. The flip chip is positioned on the electrical substrate, the electrical substrate including a thick layer of a solder mask disposed on the electrical substrate. The flip chip is heated to electrically connect the flip chip to the electrical substrate, wherein the underfill material and the solder mask combine to form a stress-relief layer when the flip chip is electrically connected to the electrical substrate.
