Source: InternetPublisher:JFET Keywords: LCD drive circuit display driver Updated: 2021/05/23
Shown is a typical LCD driving circuit HD 44780U, where (a) is a 1-line 16-character, 5×8-dot LCD
, and (b) is a 2-line, 8-character, 5×8-dot LCD .
In the figure, COMI-COM8, COM9~COM16 are the driving signals of the horizontal electrodes, and SEG1-SEG40 are the driving
signals of the vertical electrodes. (a) in the figure is a display with two sets of characters arranged horizontally, and (b) in the figure is a display with two sets of characters arranged up and down.
