Hi shaw, Daniel, The more segments that you drive the higher your current consumption will be, so your results of seeing higher current with more segments makes sense. As described in the app note Designing with MSP430 and Segment LCDs www.ti.com/.../slaa654 section 4.10, each segment on the display is like a big capacitor that is constantly being charged and discharged - the more segments you are driving, and the larger the segments, the higher the current consumption. In addition, I see in the photo of your test setup, that it looks like you may have jumper wires connecting the display to the MCU for your test - I think that could add additional capacitance when driving each segment as well. Regards, Katie
