Abstract
Disclosed is a device which includes an oscillation circuit for generating a reference clock signal CLK (osc), a display counter circuit for generating from the reference clock, a frame synchronization signal CLK (frm), a line selection reference clock signal CLK (drv), and a boost operation reference clock obtained on performing frequency multiplication of the line selection reference clock signal CLK (drv), a frequency divider circuit for inputting the frame synchronization signal CLK (frm) as a reset signal thereof and performing frequency division of the boost operation reference clock to output a boost operation clock signal CLK (dcdc), a boost circuit for performing charging and discharging operations according to the boost operation clock signal CLK (dcdc), and a driver circuit supplied with the boosted voltage of the boost circuit for driving a scan line selected the line selection reference clock signal CLK (drv).
