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 |
