  • Publication number: 20160148585
    Abstract: A liquid crystal display device supplies an active scan signal to each scan line while skipping a portion of a plurality of the scan lines, per one horizontal scan period, in a direction of the m-th to the first scan lines, by a first scan line drive circuit, and supplies the active scan signal to each scan line while skipping the portion of the plurality of the scan lines, per one horizontal scan period, in a direction of the m+1-th to the 2m-th scan lines, by a second scan line drive circuit. Therefore, the liquid crystal display device synchronizes with a timing of supplying the active signal with the first scan line drive circuit and the second scan line drive circuit, and supplies a data signal whose polarity is inverted to a positive polarity potential and a negative polarity potential per one horizontal scan period, to a data line.

  • Patent number: 9161022
    Abstract: One frame is divided into a first-half field and a second-half field, and each of the fields is further divided into subfields. In addition, a pixel is controlled to be turned on or off for each of the subfields to display a gradation. A right eye image is formed with a positive polarity in a first-half field of an odd block, and a left eye image is formed with a negative polarity in a second-half field. In an even block, a right eye image is formed with a negative polarity in a first-half field, and a left eye image is formed with a positive polarity in a second-half field.

  • Patent number: 8405993
    Abstract: An electro-optical device includes: an element substrate and an opposing substrate disposed so as to oppose each other; liquid crystals encapsulated and sealed between the two substrates; a display region that displays an image by modulating incident light based on image information; a heat dissipation member disposed opposing a second surface of the element substrate, the second surface being on the opposite side as the opposing substrate; and a thermal conductive member disposed between the element substrate and the heat dissipation member. The dimension from the end portion of where the thermal conductive member and the element substrate make contact with each other to the end portion of the display region on the second surface of the element substrate is greater than the thickness of the element substrate.

  • Patent number: 8044982
    Abstract: A driving circuit of an electro-optical device that includes scanning lines divided into two or more groups and two or more common electrodes that correspond to the two or more groups of scanning lines. The driving circuit includes a data line driving circuit and a common signal supply circuit. The driving circuit divides one field of one of the pixels into sub-fields and applies the one of the pixels with on or off voltages during the sub-fields to achieve a desired gray-scale level. During one specific sub-field, the data line driving circuit supplies a data signal of an off voltage regardless of the gray-scale level for the pixel. After the specific sub-field ends, the common signal supply circuit switches a voltage applied to a common electrode of that corresponds to the group of scanning lines that includes the selected scanning line.
