摘要： The invention simplifies the configuration of a comparators circuit used in an electrooptic device or the like, in which gradation data is stored for each pixel, to realize lower power consumption, higher definition and multiple gradation. Transistors in which gradation data D0 to D2 are respectively supplied to the gate terminals, and transistors in which gradation signals P0 to P2 resulting from counting are respectively supplied to the gate terminals are connected to form a comparator circuit. When the gradation signals P0 to P2 are less than the results of reversal of the gradation data D0 to D2, the comparator circuit is placed into a nonconductive state, while when the gradation signals P0 to P2 are equal to the results of reversal of the gradation data D0 to D2, the comparator circuit is placed into a conductive state. As a result, a pulse signal PW can be produced according to the gradation data D0 to D2 to realize a gradation display in a sub-field driving system. Also, the number of the transistors constituting the comparator circuit can be significantly decreased, as compared with a related art technique.
摘要翻译：本发明简化了在电光装置等中使用的比较器电路的结构，其中为每个像素存储了灰度数据，以实现更低的功率消耗，更高的清晰度和多个灰度级。分别向栅极端子提供灰度数据D 0〜D 2的晶体管，并且将由计数产生的灰度信号P 0〜P 2分别提供给栅极端子的晶体管连接形成比较电路。当灰度信号P 0至P 2小于灰度数据D 0至D 2的反转结果时，比较器电路处于非导通状态，而当灰度信号P 0至P 2等于将灰度数据D 0反转为D 2的结果，将比较器电路置于导通状态。结果，可以根据灰度数据D 0至D 2产生脉冲信号PW，以在子场驱动系统中实现灰度显示。此外，与现有技术相比，构成比较器电路的晶体管的数量可以显着降低。

With the invention, one field is divided into a plurality of sub-fields, such that each pixel is turned on or off in each of the sub-fields so that the proportion of the period during which each pixel is turned on to the period during which the associated pixel is turned off within the one field corresponds to the proportion according to the tone data. Further, when each pixel is turned on, either a first voltage which is higher than a constant reference voltage applied to a counter electrode or a second voltage which is lower than the reference voltage is applied to a pixel electrode of the associated pixel, and when the pixel is turned off, a voltage equal to the reference voltage is applied to the pixel electrode of the pixel.

摘要： The invention reduces power consumption when, for example, a mobile personal computer is in a power-saving mode or when a cellular phone is in a wait mode, in an electro-optical apparatus, such as a liquid crystal display of the subfield drive type used as a display apparatus for various apparatuses. Three different settings “64”, “16” and “2” are enabled as the number of gray scale levels in an electro-optical apparatus, the number of subfields becoming smaller as the number of gray scale levels is reduced. When a large number of gray scale levels is not required (when in the power-saving mode, the wait mode, etc.), a low number of gray scale levels is set, so that the own capacitance of a liquid crystal layer and storage capacitance are charged and discharged less often.
