摘要： In order to minimize light diffraction along the direction of switching and more particularly light diffraction into the acceptance cone of the projection optics, in the present invention, mirrors are provided which are not rectangular. Also, in order to minimize the cost of the illumination optics and the size of the display unit of the present invention, the light source is placed orthogonal to the rows (or columns) of the array, and/or the light source is placed orthogonal to a side of the frame defining the active area of the array. The incident light beam, though orthogonal to the sides of the active area, are not however, orthogonal to any substantial portion of sides of the individual mirrors in the array. Orthogonal sides cause incident light to diffract along the direction of mirror switching, and result in light ‘leakage’ into the on-state even if the mirror is in the off-state. This light diffraction decreases the contrast ratio of the mirror. The mirrors of the present invention result in an improved contrast ratio, and the arrangement of the light source to mirror array in the present invention results in a more compact system.

摘要： A touch sensor pattern with a secondary sensor formed substantially as part of the touch sensor pattern is provided. By forming the secondary sensor substantially as part of the touch sensor pattern, where the secondary sensor can be held at a steady state or ground during a touch scan cycle of the touch sensor, an overall thickness of the stackup at the area of the touch sensor where the secondary sensor is formed can be significantly reduced. The reduction in the thickness can allow more space for other hardware such as a device battery, for example. Moreover, grounding the secondary sensor can shield the touch sensor pattern at the area of the touch sensor pattern where the secondary sensor is formed, during a touch scan cycle.

摘要： The present invention provides a method and apparatus of converting a stream of pixel data in space and time into a stream of bitplane data. In particular, the present invention converts the pixel data stream according to a predetermined output format. The apparatus of the present invention receives the pixel data in a “real-time” fashion, and dynamically performs predefined permutations so as to accomplish the predefined transpose operation. Alternatively, the pixel data are stored in a storage medium, and the apparatus of the present invention retrieves the pixel data and performs the predefined permutation to accomplish the predefined transpose operation. The methods and apparatus disclosed herein are especially useful for processing a high-speed stream of digital data in a flow-through manner and suitable for implementation in a hardware video pipeline. The control signal fanout and gate count of this invention are reduced compared to currently available similar techniques for converting pixel data into bitplane data.

摘要： Methods and apparatus for selectively updating memory cells of a memory cell array are provided. The memory cells of each row of the memory cell array are provided with a plurality of wordlines. Memory cells of the row are activated and updated by separated wordlines. In an application of display systems using memory cell arrays for controlling the pixels of the display system and pulse-width-modulation (PWM) technique for displaying grayscales, the pixels can be modulated by different PWM waveforms. The perceived dynamic-false-contouring artifacts are reduced thereby. In another application, the provision of multiple wordlines enables precise measurements of voltages maintained by memory cells of the memory cell array.

摘要： A voltage storage cell circuit includes an access transistor and a storage capacitor, wherein the source of said access transistor is connected to a bitline, the gate of said access transistor is connected to a wordline, and wherein the drain of said access transistor is connected to a first plate of said storage capacitor forming a storage node, and wherein the second plate of said storage capacitor is connected to a pump signal. This arrangement allows for a novel pixel circuit design with area requirements comparable to that of a 1T1C DRAM-like pixel cell, but with the advantage of an output voltage swing of the full range allowed by the breakdown voltage of the pass transistor. A spatial light modulator such as a micromirror array can comprise such a voltage storage cell.
