    摘要: A method of controlling the capacitance of the TFT-LCD storage capacitor is provided. The gate dielectric layer of the TFT is composed of a silicon nitride layer, a dielectric layer and a silicon nitride layer, and the etching selectivity of the amorphous silicon layer over the dielectric layer is not less than about 5.0. Therefore, the dielectric layer can be an etching stop layer when a doped and an undoped amorphous silicon layers are etched to form source/drain stacked layers or a conductive layer is etched to form a gate on the gate dielectric layer. Hence, the dielectric layer thickness can be controlled; thereby the capacitance of the storage capacitor can be controlled.

    摘要: Techniques and tools for selecting search ranges and/or motion vector ranges during motion estimation are described. For example, a video encoder performs motion estimation constrained by a first search range, which results in multiple motion vectors. The encoder computes motion vector distribution information for the motion vectors. To compute the distribution information, the encoder can track the motion vectors in a histogram and count how many of the motion vectors fall within each of multiple intervals for the distribution information. The encoder then selects a second search range and performs motion estimation constrained by the second search range. Selecting the second search range can include selecting a motion vector range, which in some cases in effect determines the second search range.
