ABSTRACT:
A data-line drive circuit controls a current value of a control signal in every cycle T1based on upper 8-bit digital data DAB of digital data In, and performs pulse-width control in a cycle T2based on lower 2-bit digital data SUB of the digital data In for the portion which is D/A-converted based on the same digital data of the control signal. It is thus possible to provide an electronic circuit suitable to inhibit a variation in the luminance so as to control the luminance levels of pixels with high precision.
