20090135209 | ELECTRO-OPTICAL DEVICE - 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. | 05-28-2009 |
20100225675 | DISPLAY DEVICE, ELECTRONIC APPARATUS AND DRIVING CODE GENERATING CIRCUIT - A display device displays a gray scale by applying a voltage to a display element for each of a plurality of subfields. The display device includes a predetermined code storage unit that stores a predetermined code, in which indication values designating the voltage are arranged, a compression code storage unit that stores a compression code, which includes a first portion designating a number of the indication values and a second portion designating an identifier of the predetermined code, and a developing unit that generates a driving code according to a continuous code, in which indication values designating a first voltage are arranged by the number of the indication values designated by the first portion of the compression code, and a predetermined code corresponding to the identifier designated by the second portion of the compression code. | 09-09-2010 |
20110242763 | ELECTRO-OPTICAL DEVICE AND ELECTRONIC APPARATUS - 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. | 10-06-2011 |
20120236132 | ELECTRO-OPTICAL DEVICE, METHOD OF DRIVING ELECTRO-OPTICAL DEVICE, AND ELECTRONIC APPARATUS - 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. | 09-20-2012 |

20080231587 | DISPLAY DEVICE, METHOD FOR DRIVING DISPLAY DEVICE, AND ELECTRONIC APPARATUS - The invention relates to a display device that performs gradation display by means of a sub-field driving scheme. The display device according to an aspect of the invention has a display area in which a plurality of pixels is arrayed, where the display device controls an ON/OFF state for each of the plurality of pixels for each of a plurality of sub fields that make up one field. One part of the plurality of sub fields constitutes a first time period, whereas the other part of the plurality of sub fields constitutes a second time period. The display device according to an aspect of the invention includes: a first storing section that pre-stores, for each of the sub fields that belong to the first time period, a gradation that is to be displayed and an ON/OFF state of the pixel in association with each other; a first converting section that looks up the first storing section so as to convert an image signal that indicates a gradation that is to be displayed into a first sub-field data that specifies an ON/OFF state of the pixel for each of the sub fields that belong to the first time period; a temperature-data acquiring section that acquires a temperature of the display area; a second storing section that pre-stores, for each of the sub fields that belong to the second time period, a temperature of the display area and an ON/OFF state of the pixel in association with each other; a second converting section that looks up the second storing section so as to convert the temperature acquired by the temperature-data acquiring section into a second sub-field data that specifies an ON/OFF state of the pixel for each of the sub fields that belong to the second time period; a combining section that combines the first sub-field data and the second sub-field data so as to generate a combined sub-field data that specifies an ON/OFF state for each of the plurality of sub fields that make up one field; and a driving section that controls an ON/OFF state for each of the plurality of pixels for each of the plurality of sub fields on the basis of the combined sub-field data. | 09-25-2008 |
20150123959 | LIQUID CRYSTAL DISPLAY DEVICE, METHOD FOR DRIVING LIQUID CRYSTAL DISPLAY DEVICE, AND ELECTRONIC APPARATUS - 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. | 05-07-2015 |
