Abstract: This disclosure provides implementations of dither-aware image coding processes, devices, apparatus, and systems. In one aspect, a portion of received image data is selected. First spatial domain values in the selected portion of the image data are transformed to first transform domain coefficients. Second spatial domain values in a designated dither matrix are transformed to second transform domain coefficients. A ratio of each of the first transform domain coefficients to a respective second transform domain coefficient is determined. The first transform domain coefficients are selectively coded in accordance with the determined ratios to define coded first transform domain coefficients. A reverse transformation is performed to transform the coded first transform domain coefficients to third spatial domain values defining a coded portion of the image data. By way of example, transformations such as discreet cosine transforms or discreet wavelet transforms can be used.

Abstract: This disclosure provides systems, methods and apparatus for fabricating thin film transistor devices. In one aspect, a substrate having a source region, a drain region, and a channel region between the source region and the drain region is provided. The substrate also includes an oxide semiconductor layer, a first dielectric layer overlying the channel region, and a first metal layer on the dielectric layer. A second metal layer is formed on the oxide semiconductor layer overlying the source region and the drain region. The oxide semiconductor layer and the second metal layer are treated to form a heavily doped n-type oxide semiconductor in the oxide semiconductor layer overlying the source region and the drain region. An oxide in the second metal layer also can be formed.
