  • Publication number: 20230068861
    Abstract: In an electro-optical device, a first substrate used in an electro-optical panel is provided with a temperature-detecting element, and a wiring substrate connected to the first substrate is provided with third wiring electrically connected to first wiring of the first substrate, and fourth wiring electrically connected to second wiring of the first substrate. The wiring substrate is provided with an electrostatic protection circuit. The electrostatic protection circuit includes a first electrostatic protection circuit provided inside a driving integrated circuit, and a second electrostatic protection circuit including a capacitance element mounted on the wiring substrate. Accordingly, even when static electricity invades the third wiring and the fourth wiring from a connector side, the surge can be released via the electrostatic protection circuit.

  • Patent number: 10878765
    Abstract: A plurality of signal lines are classified into k signal line groups (where k is an integer equal to or greater than 2). When the k signal line groups are supplied with an image signal during a horizontal scanning period, a driving unit supplies some of the k signal line groups with a precharge signal and subsequently an image signal, and does not supply the remainder of the k signal line groups with the precharge signal and supplies the remainder of the k signal line groups with the image signal.

  • Patent number: 10199002
    Abstract: A first supply circuit outputs data signals to odd-numbered distribution circuits, and outputs selection signals to all of distribution circuits. A second supply circuit outputs data signals to even-numbered distribution circuits. The odd-numbered distribution circuits distribute the data signals to signal lines using the selection signals. The even-numbered distribution circuits distribute the data signals to signal lines using the selection signals. The first supply circuit outputs the data signals generated based on digital data signals which are basic signals of the data signals and an adjustment value, to the distribution circuits.

  • Patent number: 10032804
    Abstract: An electro-optic apparatus includes an element substrate, a pixel region including a first and second pixel formed on the element substrate, a first terminal formed on the element substrate, a second terminal formed on the element substrate, located opposite of the pixel region with the first terminal being interposed between the pixel region and the second terminal, a first wiring extending from the first terminal included in a path for transmitting to the first pixel, a first signal having been input to the first terminal and a second wiring extending from the second terminal included in a path for transmitting to the second pixel, a second signal having been input to the second terminal. Further, a difference between a resistance of the path for transmitting the first and second signal is made smaller than a resistance difference due to a difference between a length of the first and second wiring.

  • Patent number: 9607563
    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.
