Abstract: A semiconductor device includes a substrate, a semiconductor layer provided on the substrate, a gate electrode, a drain electrode, and a source electrode provided so as to dispose the gate electrode between the drain electrode and the source electrode, wherein via holes are provided in the substrate and the semiconductor layer, the via holes overlap with the source electrode when viewed from a thickness direction of the substrate, penetrate through the semiconductor layer and the substrate, and are arranged in an extending direction of the source electrode, the via holes include a first via hole closest to a first end of the gate electrode to which a signal is inputted, the first via hole is in contact with the source electrode with a first area, and the first area is the smallest of a plurality of areas in which the via holes are in contact with the source electrode.

Abstract: A chroma adjustment method, an electronic device and a non-transitory computer-readable storage medium are provided. The input color data is converted into preset color data in a preset color space. The preset color data is processed to determine a maximum chroma value among multiple chroma values for each of which the number of corresponding pixels is a peak in a chroma statistical graph, and a maximum luminance value of pixels corresponding to the maximum chroma value is determined. A chroma adjustment coefficient is obtained, according to the maximum chroma value, the maximum luminance value and a chroma mapping curve. The input color data is adjusted based on the chroma adjustment coefficient, to obtain output color data.
