Character LCD Modules
Character LCD Modules are Alpha-Numeric Dot Matrix LCD displays use Super Twisted Nematic (STN) and Film Compensated STN (FSTN) technology. They have all of the driving and control circuitry packaged with the LCD glass, providing an easy to use digital interface to the user. The characters displayed usually have a fixed 5×7 pixel matrix used to display alpha-numeric text. The text characters displayed by these modules are controlled, and refreshed by, the LCD Character Module so the user only needs to send simple ASCII characters to the Modules internal RAM. Pacific Display Devices offers Character LCD Modules from 1 line by 8 characters, to 4 lines by 40 characters.
