In the timing generating circuit, which is formed on an insulating substrate and generates output pulses SRFF1out to SRFFnout having different frequencies based on a master clock MCK, a clock generating circuit (11) generates an operating clock having a lower frequency than the master clock MCK frequency. Then, a counter section (12) operates based on this operating clock and successively outputs shifted pulses S/R1out to S/Rmount from shift registers (121-1) to (121-m). An output pulse generating section (13) generates output pulses SF1out to SFnout based on combinations of the shifted pulses S/R1out to S/Rmount.

摘要： A power supply generating circuit, a display apparatus incorporating the same, and a portable terminal device using the display apparatus as an output display unit are provided. In a DC-DC converter having a charge pump circuit (31), a voltage dividing circuit (32), and a regulation circuit (33), p-channel MOS transistors (Qp21, Qp22, Qp31) are turned on/off based on an enable pulse enb to make the voltage dividing circuit (32) and a comparator (41) active only for a period of regulation time and inactive otherwise. This can cause a current to flow in voltage-divider resistors (R1, R2) and the comparator (41) only for a certain period of time required for the regulation operation, thus reducing the power consumption loss caused by a constant current flow in the voltage-divider resistors (R1, R2) and the comparator (41).

摘要： A display device is provided and includes a first photosensor that detects the light amount of ambient light of a display area, a second photosensor that detects dark current arising when light is blocked, and changeover switches that select the first photosensor and the second photosensor. The display device further includes a comparator that compares the output of the selected first photosensor or second photosensor with a predetermined reference value, and control means that calculates the difference between the comparison result by the comparator with the first photosensor and the comparison result by the comparator with the second photosensor and controls the amount of light supplied to the display area corresponding to the calculation result. This configuration suppresses the influence of a detection error due to variation in the performance between the photosensors applied to the display device to thereby accurately adjust the amount of light supplied to the display area.
