  • Patent number: 7190338
    Abstract: An image display device includes two data signal line drive circuits and two scan signal line drive circuits configured differently from each other. Different data signal line drive circuits and scan signal line drive circuit are compatible with different display formats. A display can be produced in the most suitable display format, and power consumption also can be reduced, by switch operating drive circuits according to the kind of input video and environmental conditions. Further, an image can be written over another image by writing video signals to signal lines with a time lag using a plurality of drive circuits; therefore, a superimposed display can be produced without externally processing the video signals. Thus, both a satisfactory image display and low power consumption can be achieved in an image display device.

  • Patent number: 7173598
    Abstract: A shift register circuit includes a plurality of latch circuits connected in series to sequentially transfer a pulse signal ST from one to another, a clock signal line transmitting a clock signal CLK, and a plurality of switching circuits performing electrical connection and disconnection between the clock signal line and the plurality of latch circuits. Upon turning on the shift register, at least one of the switching circuits electrically disconnects at least one of the latch circuits from the clock signal line. During an initialization period immediately after power has been turned on, the frequency of the clock signal CLK is lower than in a normal operation period and gradually increases toward the frequency used in the normal operation period.

  • Patent number: 7151523
    Abstract: A driving circuit of the present invention includes a signal line switching circuit section that connects each signal line with two adjacent ones of output stages of a shift register circuit, one of the two adjacent ones of output stages following the other, switches over so that the signal lines are, in the switching-over manner and in concert, driven either by the following output stages or by the followed output stages. Thus, it is possible to provide a driving circuit that can be freely placed in any manner, is suitable for many purposes, and is capable of switching shifting directions without needing inversion of a clock signal and without causing shift of pixels, and switching the shifting directions with a simple arrangement even if there are an even number of signal lines for driving effective pixel columns.

  • Publication number: 20060181502
    Abstract: A signal line driving circuit includes a shift register having a plurality of shift circuits, each of which shifts a start pulse successively to the next stage, synchronizing with the timing of a clock signal. In this signal line driving circuit, shift pulses are outputted from an AND gate based on output pulses of two adjacent shift circuits. Meanwhile, a width specifying pulse for specifying a pulse width of the shift pulse is inputted via a transistor whose ON/OFF operation is controlled by the shift pulse. A logical operation circuit operates an AND of the shift pulse and the width specifying pulse and outputs the result of operation to a signal line. When the shift pulse is non-active, the transistor becomes OFF, which causes the signal line transmitting the width specifying pulse to be disconnected from the signal line driving circuit, thereby reducing a capacitive load of wiring.

  • Publication number: 20060161278
    Abstract: An operation section housing and a display section housing are connected by a rotatable hinge having a structure in which the display section housing rotates with the rotatable hinge serving as the central rotational axis. The display section housing has three built-in speakers in predetermined positions of a display. A personal digital assistant detects the angle of the rotatable hinge and identifies the speaker located in the leftmost side and the speaker located in the rightmost side relative to an upright display image displayed on the display. Then, the left audio is output from the left side of the upright display image and the right audio is output from the right side of the upright display image.

  • Patent number: 7079096
    Abstract: Before a potential of counter electrode is changed, a potential holding circuit fixedly holds potentials of data signal lines S during a non-selective period of scanning signal lines G. This prevents the potentials of the data signal lines S from being an undesirably large potential, which is caused by coupling capacitors between the counter electrode and each data signal line S, whereby it is possible to supply to the pixel capacitor an electric charge corresponding to a gradation to be displayed, by using the relatively low potentials of the data signal lines S. This lowers a power supply voltage of a data signal driving circuit SD, thus reducing the electric power consumption. In short, with this arrangement, a liquid crystal display device can perform an opposed AC drive for line-inversion drive, frame-inversion drive and the like, by low power supply voltage of the data signal line driving circuit SD, thereby reducing the electric power consumption.

  • Patent number: 7079106
    Abstract: A source driver of the present invention includes a bypass switch which connects two source lines with each other. A video signal to one of the source lines is simultaneously supplied to the other source line. The source driver is thus capable of indirectly transmitting a video signal of a video line, supplied to one source line, to the other source line. Therefore, according to the source driver, it is possible to transmit video signals on fewer image lines than the number of source lines. As a result, it is possible to significantly lower power consumption.

  • Patent number: 7034795
    Abstract: The scanning signal line driving circuit sequentially carries out active driving with respect to each set of a certain number of scanning signal lines which are adjacent to each other in a vertical direction, and when carrying out an actual writing with respect to a first set of a certain number of pixel lines adjacent to each other in the vertical direction, carries out pre-charging with respect to a second set of the certain number of pixel lines to which the actual writing is carried out next with a potential of a same polarity as that of the first set of the certain number of pixel lines. In this manner, it is possible to provide a matrix image display device with no irregularities in display quality and is capable of matching the apparent vertical resolution of the device to that of the image source, when using an image signal of vertical resolution lower than the maximum physical vertical resolution of the device.

  • Patent number: 6940500
    Abstract: A potential of a data signal line S during a scanning period is charged to a substantially intermediate potential of a data signal at a corresponding frame. Thus, extremely large dispersion does not occur in a potential of each pixel capacitor with respect to a potential of the data signal line S, so that it is possible to restrict dispersion of a leak current flowing via an active element of each pixel. Thus, potential variation of a pixel PIX is reduced, so that it is possible to improve display quality during a non-scanning period. That is, in an active-matrix-type liquid crystal display, when a frame frequency is reduced by setting the non-scanning period to be sufficiently larger than a scanning period while a standby image is being displayed so as to realize low power consumption, the display quality is improved.
