In this paper, we developed saccade-induced line displays including flashing period controllers. The displays speeded up the flashing period of one line using LED drivers and Arduino Uno equipped with AVR microcomputers. It was shown that saccades were easily induced when the observer alternately looks at the two fast flashing line displays apart. Also, we were able to find the optimum flashing period using a controller that can speed up the flashing period and change its speed. We found that the relationship between the viewing angle of the observer and the optimum flashing period is almost proportional.

An RGB-LED driver with a pulse-skipping-modulation boost converter is proposed to fix the reference voltage for lowering down the circuit complexity. A high-voltage LDO and a bandgap reference circuit are built into the chip. The proposed converter outputs a different voltage in response to a different color of LEDs. The output voltages for driving six red, six green, and six blue LEDs in series are 13.5V, 20V, and 21.5V, respectively. The proposed LDO and bandgap reference circuit work with supply voltages from 8V to 12V. The settling time for changing colors is lower than 300µs, better than the unfixed-reference-voltage methods. The proposed circuit was fabricated by using 0.25-µm BCD 60V technology, and the chip area was 1.9 × 1.7mm2.
