Unlike dynamic drives, static drives face the disadvantage of having to increase the driver-chip number in step with the rising segment count. However, because pattern division by grid is not necessary, the static drive offers an advantage by placing few restrictions on the pattern shape or position. This advantage becomes apparent in systems that emphasize design, such as displaying patterns having custom designs. Additionally, static drives operate at low voltages, down to 10 V. Static drives will yield lower power consumption, longer product life, and less noise than dynamic drives, when displaying the same kinds of patterns. Unlike dynamic drives, static drives allow operation without exhibiting flickering by grid scans.
Engineers can easily raise luminance by increasing voltage.
Engineers prefer dynamic drives in systems that display text in 5 x 7 dot matrices. Static drives are difficult to use when these image displays require a large segment total.
