Patent ID: 11094241

Abstract:
A display driver (100) includes terminals (TSEG1 and TSEG2) and a drive circuit (130). The terminal (TSEG1) can be connected to a segment electrode (ESEG1). The terminal (TSEG2) can be connected to a segment electrode (ESEG2) whose area is larger than the area of the segment electrode (ESEG1). The drive circuit (130) outputs a PWM segment drive signal (SSEG1) to the terminal (ESEG1), and outputs a PWM segment drive signal (SSEG2) to the terminal (TSEG2). When the same effective voltage is applied to the segment electrode (ESEG1) and the segment electrode (ESEG2), the duty ratio of the segment drive signal (SSEG1) is smaller than the duty ratio of the segment drive signal (ESEG2).
