20100214328IMAGE DISPLAY DEVICE, ELECTRONIC APPARATUS, AND IMAGE DISPLAY METHOD - An image display device includes a motion detector that detects a magnitude of motion between frames from image data containing an image to be displayed, a frame number adjuster that adjusts the number of frames per unit time based on a detection result from the motion detector, a sub-frame number adjuster that adjusts the number of sub-frames included in one frame based on the detection result, and a controller that controls the frame number adjuster and the sub-frame number adjuster such that: when the detected magnitude is large, the number of frames is made larger and the number of sub-frames is made smaller in comparison with the case where the detected magnitude is small; and when the detected magnitude is small, the number of frames is made smaller and the number of sub-frames is made larger in comparison with the case where the detected magnitude is large.08-26-2010
20120062535DRIVING METHOD OF ELECTRO-OPTICAL DEVICE, ELECTRO-OPTICAL DEVICE, AND ELECTRONIC APPARATUS - In an electro-optical device, a liquid crystal element can be driven more appropriately.03-15-2012
20120091479ELECTROOPTIC DEVICE AND ELECTRONIC APPARATUS - Pixel electrodes having reflectivity are arranged at a predetermined pitch in a matrix form on an effective display region on an opposed surface of an element substrate. A first conductive pattern which is formed by the same layer as the pixel electrodes is provided on an ineffective display region which is at an outer side with respect to the effective display region and at an inner side with respect to a sealing region when seen from the above. A second conductive pattern which is formed by the same layer as the pixel electrodes is provided on the sealing region. An area density of the second conductive pattern is smaller than an area density of the first conductive pattern when seen from the above.04-19-2012
20120099067ELECTRO-OPTICAL DEVICE AND ELECTRONIC EQUIPMENT - In a display region, pixel electrodes are arranged with a predetermined pitch in a matrix. Dummy pixel electrodes provided in a dummy display region surrounding the display region are formed from the same layer as the pixel electrodes, and are arranged in an island shape so as to have the same size and pitch as the pixel electrodes. The dummy pixel electrodes are connected to each other via a wire positioned under the pixel electrodes.04-26-2012
20120242914LIQUID CRYSTAL DEVICE AND PROJECTION-TYPE DISPLAY APPARATUS - In an element substrate of a liquid crystal device, in a peripheral region interposed between an image display region and a seal material, a peripheral electrode to which a potential is applied for trapping ionic impurities which is different from a common potential applied to a dummy pixel electrode or the like is formed. In the peripheral electrode, an electrode width of a first portion opposing a sealing material provided at a liquid crystal injection opening of the seal material is set to be greater than electrode widths of the other portions.09-27-2012

20110115768METHOD OF DRIVING ELECTRO-OPTICAL DEVICE, ELECTRO-OPTICAL DEVICE, AND ELECTRONIC APPARATUS - An electro-optical device includes: a data line driver applying the signal potential in such a manner that a writing polarity is reversed more than once in the field time period, and the writing polarity of each of sub field time periods making up a certain field time period is the opposite of the writing polarity of the corresponding one of sub field time periods making up the next field time period; a scanning line driver applying the scanning signal in such a manner that a total length of the sub field time periods in which writing in one polarity is performed in each cycle of two consecutive fields one of which is an odd field and the other of which is an even field is different from a total length of the sub field time periods in which writing in the other polarity is performed in the each cycle of two consecutive fields.05-19-2011

20110158573THRUST ROLLER BEARING AND METHOD FOR MANUFACTURING THRUST RACE THEREOF - A thrust race of a thrust roller bearing has a race portion and a cylindrical portion extending from the race portion in an axial direction. At a plurality of locations along a circumferential direction on the cylindrical portion, cutout portions are formed such that each of the cutout portions is recessed in the axial direction from a distal edge of the cylindrical portion toward the race portion. A protrusion is provided at a portion closer to the race portion from a bottom edge of each of the cutout portions such that the protrusion protrudes in a radial direction from the cylindrical portion toward a side away from the race portion. The protrusion serves as a race-retaining locking portion to prevent a race from moving out from a mating member on which the race is mounted.06-30-2011
