Abstract
To provide an electronic circuit, an electro-optical device, and an electronic apparatus, which are capable of producing digital signals having predetermined output values in accordance with digital data. A bit extending circuit 40 is constructed for producing 8-bit digital data in order to change current Im of data line driving signals output from a digital-to-analog converting circuit 30 in a manner of a high order function with respect to 6-bit image data output from a controller. Further, a single line driver 20 is constructed by connecting the bit extending circuit 40 to an input side of the digital-to-analog converting circuit 30.
Claims15
An electronic circuit, comprising:
- a shift circuit that shifts j-bit digital data (j is a natural number) to be converted into k-bit digital data (k is a natural number);
- and
- a correction circuit that is electrically coupled to the shift circuit, the correction circuit continuously changes the k-bit digital data that is obtained by the shift circuit in accordance with the change of the j-bit digital data.
An electro-optical device, comprising:
- a control circuit that outputs j-bit luminance gray scale data (j is a natural number);
- a driving circuit that generates analog driving signals based on the j-bit luminance gray scale data;
- and
- a pixel circuit that drives current driven elements based on the analog driving signals,
- the driving circuit including:
- a shift circuit that shifts the j-bit luminance gray scale data to convert the data into k-bit digital data (k is a natural number);
- a correction circuit that is electrically coupled to the shift circuit, the correction circuit continuously changing the k-bit digital data that is obtained by the shift circuit in accordance with the change of the j-bit luminance gray scale data.
