A method for optimizing image quality and a module for optimizing image quality are provided. The method includes: in a gamma adjustment phase, controlling and setting respective actual data voltages corresponding to a grey scale 0 of sub-pixels having different colors, and controlling at least two of the actual data voltages corresponding to the grey scale 0 of the sub-pixels having different colors to be different from each other, to control a gamma curve of the sub-pixels to make an absolute value of a luminance difference between the luminance of the gamma curve corresponding to each grey scale value and the luminance of a standard gamma curve corresponding to the grey scale value less than a predetermined luminance difference; and in a display phase, when a grey scale value provided to sub-pixels having different colors is 0, applying the corresponding actual data voltages to the sub-pixels having different colors.

A directional coupler is disclosed integrated on a single chip and an integrated circuit based on a standard CMOS process and relates to a field of radio frequency communication. In exemplary implementations, by using a standard CMOS process technology, the directional coupler integrated by a CMOS process is formed by a coil wound by a upper layer of metal lines, a coil wound by a lower layer of metal lines, two tuning capacitor array, and a matching resistor. Two terminals of the coil are a direct terminal and an input terminal; two terminals of the coil are a coupled terminal and an isolation terminal; the terminals of the coils and are intersected at 90&#xb0;; the coil is wound by an upper metal layer and the coil is wound by a lower metal layer. Further, the insertion loss is low and the isolation degree is large.
