Set the MODE pin condition during output discharge period.
input the horizontal shift clock signal of CK pin by shifting the phase for each line
according to the shift of the pixels connected to the same source bus line.
ff the pixels connected to the same source bus line is shifted by half the pixels, change
the clock phase 180 degrees.
Clock phase must be changed during output discharge period.
