An atom scanning system was established in order to improve scanning efficiency and achieve resolution better than 2K for flat-panel displays. The atom scanning strategy was analyzed using mathematical matrices based on fractal geometry. First, the existing PWM scanning strategies were analyzed. Next, we performed a comparative study of the performances of different scanning strategies, and illustrated that the atom scanning method exhibits the best performance. Our experimental results indicate that linearity is preferred when the weight value of 8 bits is converted to 128∶64∶32∶16∶9∶4∶2∶1 for 256 level gray-scale images. For a resolution of 1600×1600 with a clock frequency of 50 MHz, the scanning frame frequency reaches 90 Hz, while the linearity and transmission efficiency are 99.8% and 100%, respectively. Thus, the requirements of extremely high resolution and frame frequency, low clock frequency, and high linearity are satisfied.
