20100039441 | ELECTRO-OPTICAL DEVICE, METHOD OF DRIVING THE SAME, AND ELECTRONIC APPARATUS - An electro-optical device includes a pixel that has an electro-optical element with a light transmittance that changes to a predetermined value in response to an applied voltage, which changes in response to the temperature. A light source irradiates light to the pixel. A driving unit includes a predetermined number of sub-fields having the same length in one frame. The driving unit provides either an on-voltage indicating light-on or an off-voltage indicating light-off to the pixel in each of the predetermined number of the sub-fields in response to the grayscale to be displayed. A temperature measuring unit measures the temperature and outputs a temperature signal. A time controlling unit controls the length of one sub-field on the basis of the temperature signal. A light intensity controlling unit controls the intensity of the light incident on the pixel on the basis of the temperature signal. | 02-18-2010 |
20100188444 | ELECTRO-OPTICAL DEVICE, ELECTRONIC APPARATUS, AND METHOD OF DRIVING ELECTRO-OPTICAL DEVICE - An electro-optical device includes pixels that is driven in response to an ON voltage or an OFF voltage supplied to the signal lines at a time when each of scanning lines is selected, a scanning line driving circuit that sequentially selects the scanning lines in each of a plurality of subfields within a field, a signal line driving circuit that outputs the ON voltage to the signal lines in at least one temperature compensation subfield and outputs either the ON voltage or the OFF voltage to each of the signal lines in accordance with a designated gray scale of each of the pixels in each of a plurality of gray scale control subfields, which is different from the temperature compensation subfield, and a control unit that sets a time length of the temperature compensation subfield to be changed in accordance with the temperature detected by a temperature detecting unit. | 07-29-2010 |
20110001735 | ELECTRO-OPTICAL DEVICE, METHOD FOR DRIVING ELECTRO-OPTICAL DEVICE AND ELECTRONIC APPARATUS - An electro-optical device operates in a cycle of unit periods of time. Each of the unit periods of time includes a first time period, a second time period, and a third time period. The electro-optical device includes: scanning lines; data lines; potential lines; a driving section; and pixels, each of pixels including a pixel electrode. In the first time period of a certain unit period of time, the driving section writes a data potential that is in accordance with an image into the pixel electrode. In the second time period, the driving section writes a reset potential that makes a potential of the pixel electrode closer to a potential of the potential line. In the third time period, the driving section sequentially makes a transition of a potential of the potential lines from a first potential to a second potential. | 01-06-2011 |
