摘要： An article and a method for testing the assembly of that article are disclosed. The article includes a plurality of modules, at least two of the modules are capable of being placed in two different positions in the article, each module having a correct position in the article. Each module includes an aperture at a location determined by the desired position for that module in the article. The apertures are placed such that the apertures will be aligned to form a transparent channel when the modules are arranged in a predetermined pattern with respect to one another, but not when arranged in any of the possible incorrect orders. The article can be tested for assembly errors by transmitting a test light signal into the first end and testing for light that traversed all of said first transparent channel.

摘要： A combination of light source types is used to form a dynamically adjusted backlighted display with the particular combination dependant upon the desired light output at a given point in time. In one embodiment, RGB diodes are used for low brightness situations and as the brightness requirement increases white light sources are added. In another embodiment, different light source types are used to produce the different color components and optical feedback is used to control the power levels of the various diode types.

摘要： In LED back-lighted display systems where the LED driving signals are pulse width modulated, brightness of the LED is determined by the duty cycle (length of the “on” pulse). In such systems, it is possible to, from time to time, skip an LED driving pulse without the human eye detecting the absence of (or change in) color during the “skipped” LED pulse. Using this approach, it is possible to measure the intensity of the light output from each LED of a multi-color LED display. Thus, in an embodiment having three colors, such as red, green and blue, it is possible to determine the light intensity from one of the LEDs (for example, the red LED) by skipping (blanking) the input driving pulses to the green and blue LEDs at a particular point in time. During that point in time the only light coming from the display would come from the unblanked LED which, in this case would be the red LED. It is then possible to measure the intensity of the red LED light using a photosensor without use of a filter. In similar manner, and at some later point in time, the light intensity from each of the other color LEDs can be measured using the same photosensor without using a filter. By spacing the blanking periods properly, the resulting change in color of the display will not be perceived by the human eye.
摘要翻译：在LED驱动信号被脉宽调制的LED背光显示系统中，LED的亮度由占空比（“on”脉冲的长度）决定。在这样的系统中，可以不时地跳过LED驱动脉冲，而不会在“跳过”LED脉冲期间人眼检测到颜色不存在（或改变）。使用这种方法，可以测量从多个LED显示器的每个LED输出的光的强度。因此，在具有红色，绿色和蓝色三种颜色的实施例中，可以通过将输入驱动脉冲跳过（消隐）到绿色来确定来自一个LED（例如，红色LED）的光强度和蓝色LED在特定的时间点。在这个时间点，来自显示屏的唯一光将来自未曝光的LED，在这种情况下，LED将是红色LED。然后可以使用光电传感器来测量红色LED灯的强度，而不使用滤光片。以类似的方式，并且在稍后的时间点，来自每个其它颜色LED的光强度可以使用相同的光电传感器测量而不使用滤光器。通过适当地隔开消隐期，显示器的颜色变化将不被人眼察觉。

摘要： A field-sequential color light system has a light source that includes multiple color light emitting diodes (LEDs) and a spectral feedback control system that is configured to drive the color LEDs, to detect light from the color LEDs, and to adjust color-sequential drive signals in response to the light detection system. Detecting the emitted light and adjusting the color-sequential drive signals in response to the light detection allows luminance and chrominance characteristics of the emitted light from the field-sequential color light system to be maintained at desired levels as the performance of the LEDs change over time.
