    摘要: A timing generating circuit with low power consumption and a small layout area, a display apparatus including the timing generating circuit as one peripheral driving circuit, and a portable terminal including the display apparatus as a display output section are provided. 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 liquid crystal display device enabling a reduction in size and costs associated with the system as a whole, starting to display images without image distortion at power on time, and turning the screen off without image retention at power off time, a method of controlling the liquid crystal display device, and a mobile terminal incorporating the liquid crystal display device as a screen display. On a glass substrate (11) provided with a display unit (12), peripheral drive circuits such as an interface circuit (13), a timing generator (14), a reference voltage driver (15), a CS driver (18), a VCOM driver (19), and a voltage regulation circuit (20), together with a horizontal driver (16) and a vertical driver (17) are disposed. When a display reset control pulse PCI is supplied from an external source, a predetermined voltage is written into pixels while a CS voltage and a VCOM voltage adjusted to the same level as that of a pixel voltage are applied to a common-electrode-side. This allows the screen to turn white in a normally white type liquid crystal display, and to turn black in a normally black type liquid crystal display. Image distortion at power on/off time can thus be prevented.

    摘要: When a buffer is formed by using transistors having large element characteristic variations, the deviation of the timing between the input clock pulse and the reset pulse is likely to occur. When the deviation of the timing becomes larger, a malfunction is caused to occur, and an operation margin becomes smaller with respect to the variations of the element characteristics. In a timing generation circuit, which is formed on an insulating substrate and which has two TFFs (12, 13), for generating a dot clock DCK and a horizontal clock HCK whose frequencies are different in synchronization with a master clock MCK which is input external to the substrate, separate reset pulses drst and hrst are generated at a pulse generation circuit 15 with respect to the two TFFs (12, 13), and a resetting operation is performed at separate timings. Thus, a large operation margin can be ensured even when each circuit is formed by using TFTs having large element characteristic variations and a rough process rule.

    摘要: In a reference-voltage-selection-type D/A converter, the channel widths of transistors of MOS switches of gradation selecting units are weighted depending on the selected gradation. Specifically, the channel width of the MOS switches Qn11, Qn12 is represented by W0, the channel width of the MOS switches Qn13, Qp11 is represented by W1, the channel width of the MOS switches Qp12, Qn14 is represented by W2, and the channel width of the MOS switches Qp13, Qp14 is represented by W3. The channel width W3 is set to a size corresponding to the maximum capacitance of a column line, and the other channel widths W0, W1, W2 are set to satisfy the relationship: W0
