Technical Field
The invention relates to the technical field of electronics, in particular to a segment code liquid crystal driving method.
Background
A segment code liquid crystal display is frequently used in instruments, particularly, a large number of numbers and independent fixed indicators need to be displayed in some equipment, and a liquid crystal display manufacturer often has difficulty in regularly distributing various indicators due to layout problems when displaying drawings. Therefore, when a programmer is driving, it is often necessary to put together the segment codes distributed at different positions according to the display requirement to obtain a complete display, for example, 7 segment codes are required for displaying a number 8, if the segment codes are distributed in different SEG pins. A separate function is needed to screen the 7 segment codes together. If the display internal amount is not much better. If a large number of numbers are displayed, a large number of functions are required. A large amount of time of developers is wasted, the program is called to waste efficiency, and the maintenance is very troublesome in the future.
