摘要:
A light emitting element driving differential switch (2) includes first and second transistors (M1, M2). A third transistor (M3) is connected as an auxiliary switch in parallel to the first transistor (M1) whose drain is connected to a light emitting element (1). A third switch driving signal (IN3) is input to the third transistor (M3) to turn ON the third transistor (M3) at a slightly earlier point in time than when complementary switch driving signals (IN1, IN2) are input to the first and second transistors (M1, M2) to drive the first and second transistors (M1, M2). This improves the rising characteristics of the output from the light emitting element having a high power level.

发光元件驱动差动开关(2)包括第一和第二晶体管(M 1,M 2)。 第三晶体管(M 3)作为辅助开关并联连接到漏极连接到发光元件(1)的第一晶体管(M 1)。 第三开关驱动信号(IN 3)被输入到第三晶体管(M 3),以在比互补开关驱动信号(IN 1,IN 2)为更早的时间点稍稍接通第三晶体管(M 3) 输入到第一和第二晶体管(M 1,M 2)以驱动第一和第二晶体管(M 1,M 2)。 这改善了具有高功率电平的发光元件的输出的上升特性。
