Electro-optical device, method of driving the same, and electronic apparatus

Abstract

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.

1 . An electro-optical device, comprising:
 a pixel that has an electro-optical element of which brightness is controlled by at least one datum;   a driving unit that supplies a voltage corresponding to the at least one datum to the pixel in each of a plurality of sub-fields;   a temperature measuring unit that measures the temperature and outputs a temperature signal; and   a time controlling unit that controls a length of at least one sub-field of the plurality of sub-fields on the basis of the temperature signal.   
     
     
         2 . The electro-optical device according to  claim 1 , wherein the time controlling unit controls a length of each of the plurality of sub-fields. 
     
     
         3 . The electro-optical device according to  claim 1 ,
 wherein:   the time controlling unit controls a length of one sub-fields of the plurality of sub-fields; and   a ratio of a response time during which a light transmittance of the electro-optical element changes to a predetermined value after the voltage is supplied to the pixel to the length of the one sub-field is constant even if the temperature changes.
