摘要： A system for maintaining a substantially constant display white point over an extended period of operation of a color display formed by an array of multiple pixels in which each of the pixels includes multiple subpixels having different colors, and each of the subpixels includes a light emissive device. The display is generated by energizing the subpixels of successively selected pixels, and the color of each selected pixel is controlled by the relatives levels of energization of the subpixels in the selected pixel. The degradation behavior of the subpixels in each pixel is determined, and the relative levels of energization of the subpixels in each pixel are adjusted to adjust the brightness shares of the subpixels to compensate for the degradation behavior of the subpixels. The brightness shares are preferably adjusted to maintain a substantially constant display white point.

摘要： Methods and systems to provide baseline measurements for aging compensation for a display device are disclosed. An example display system has a plurality of active pixels and a reference pixel. Common input signals are provided to the reference pixel and the plurality of active pixels. The outputs of the reference pixel is measured and compared to the output of the active pixels to determine aging effects. The display system may also be tested applying a first known reference current to a current comparator with a second variable reference current and the output of a device under test such as one of the pixels. The variable reference current is adjusted until the second current and the output of the device under test is equivalent of the first current. The resulting current of the device under test is stored in a look up table for a baseline for aging measurements during the display system operation. The display system may also be tested to determine production flaws by determining anomalies such as short circuits in pixel components such as OLEDs and drive transistors.

摘要： In embodiments, a hybrid wafer or substrate dicing process involving an initial laser scribe and subsequent plasma etch is implemented for die singulation. The laser scribe process may be used to cleanly remove a mask layer, organic and inorganic dielectric layers, and device layers. The laser etch process may then be terminated upon exposure of, or partial etch of, the wafer or substrate. In embodiments, a hybrid plasma etching approach is employed to dice the wafers where an isotropic etch is employed to improve the die sidewall following an anisotropic etch with a plasma based on a combination of NF3 and CF4. The isotropic etch removes anisotropic etch byproducts, roughness, and/or scalloping from the anisotropically etched die sidewalls after die singulation.

摘要： A method and apparatus is disclosed for determining the central ray of scanning an object on a detector in a computer tomography system. The method comprises producing a fan beam of x-rays at a fixed x-ray source and detecting the x-rays at the detector. The scanning projection data of the object under examination is received and the object is rotated under examination using a manipulator. After calculating the opposite projection pixel position and projection angle for each pixel, a mismatching is measured between the grey levels of all pixels and their calculated opposite projection pixels with a set of assumed central ray, and identifying the minimum of the measurement as the true central ray.

摘要： A method and apparatus for converting a high precision digital word into a high precision analog value is disclosed. A sigma delta modulator applies a digital input signal to a dither signal to generate a combined signal for sampling. A digital-to-analog converter quantizes the combined signal. An analog filter provides a cutoff at a bandwidth of interest to remove out of band quantization noise and signals. An I transfer function and a Q transfer function can be coupled between the sigma delta modulator and the digital-to-analog converter for mapping of the combined signal. The apparatus can also include a phase interpolator for receiving the output signal and outputting a clock recovery phase.

摘要： A technique determines whether configured logical bandwidth allotments for logical channels are supported by maximum available physical bandwidths of physical channels assigned to those logical channels. The technique establishes a bandwidth-constraint directed acyclic graph (DAG) or “BCD” based on novel relationship rules between vertexes of the BCD that represent logical channels or unions of logical channels as well as the underlying physical channels and their maximum available bandwidth constraints. Once the BCD is established, the vertexes of the BCD may be traversed (e.g., from in-neighbor vertexes to out-neighbor vertexes) to determine whether their constraints are met.
