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： 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 black-level reference-voltage generation circuit is disposed in a vicinity of an input-and-output pad section, and a power-supply line for the black-level reference-voltage generation circuit is connected to a power-supply line for a reference-voltage generation circuit for the other gradation levels at a position in a vicinity of the input-and-output pad section. With this, the resistance of the wiring resistor of the power-supply line of the black-level reference-voltage generation circuit is made as low as it can be ignored. As a result, a voltage drop caused by the wiring resistor of a black-level reference voltage is eliminated.

摘要： A liquid crystal display is provided that allows miniaturization, cost lowering, thickness reduction, and saving of unnecessary spaces of the device, and enhancement of the reliability of the device. If a variable resistor is used to set the DC potential of a VCOM potential, miniaturization of a liquid crystal display is precluded since the size of the variable resistor is large. A DA converter (20) is used instead of a conventional variable resistor as a unit for setting (adjusting) the DC potential of a VCOM potential (counter electrode voltage), and the DA converter (20) is formed on the same glass substrate (11) by using the same process as those of a display area part (12), to thereby achieve miniaturization of the liquid crystal display.

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.
