发明名称 LIGHT-EMITTING ELEMENT DRIVING CIRCUIT
摘要 A light-emitting element driving circuit includes a PWM signal output circuit configured to output a plurality of PWM signals each having one logic level whose duty ratio corresponds to gradation data and each corresponding to each of a plurality of light-emitting elements, on the basis of the gradation data indicating brightness of each of the plurality of light-emitting elements. A driving signal output circuit is configured to change the duty ratio of each of the plurality of inputted PWM signals to output the plurality of changed PWM signals as a plurality of driving signals, on the basis of instruction data for changing the brightness of the plurality of light-emitting elements. A driving circuit is configured to drive the plurality of light-emitting elements on the basis of a duty ratio of each of the plurality of driving signals.
