摘要： The method includes the steps of: (a) supplying second digital data, in place of first digital data that should originally be supplied, to a current drive circuit to allow the current drive circuit to supply a drive current corresponding to the second digital data during a first time period; and (b) supplying, after step (a), the first digital data to the current drive circuit to allow the current drive circuit to supply a drive current corresponding to the first digital data during a second time period. In step (a), the digital value of the second digital data is determined based on the digital value of the first digital data so that write of a drive current corresponding to the first digital data into an circuit to be driven is completed with the supply of the drive currents during the first and second time periods.

摘要： A current drive circuit supplies a driving current to a pixel portion included in a current-driven display panel. A driving current generator includes an output terminal for supplying the driving current. A protective transistor has a drain connected to the pixel portion, a source connected to the output terminal, and a gate to which a first bias voltage is supplied. The first bias voltage has a voltage level lower than or equal to a voltage level obtained by adding the threshold voltage of the protective transistor to the breakdown voltage of the driving current generator.

摘要： N drivers convert n digital values into n voltages. N amplifiers amplify the n voltages, thereby generate n drive voltages. An amplifier voltage supply supplies an amplifier voltage for driving the n amplifiers. An amplifier voltage controller detects a maximum digital value among a plurality of digital values, and sets the amplifier voltage to a voltage value dependent on the maximum digital value.
