It seems that every two years the controller driver used on Liquid Crystal Displays is discontinued and replaced by another manufacturer. The challenge to this is that the word ‘equivalent’ is not the same as ‘100% exact, drop-in match’
When the supplier of a Controller Driver discontinues their current product, the monochrome LCD module manufactures are forced to switch to an equivalent. When this happens we highly suggest the customer test a sample of the new controller/driver before ordering production quantities. Our estimate is that a customer can swap between different controller drivers 99% of the time without having to modify or change their firmware. However, there is a 1% failure rate.
Some Controller Driver manufactures include Sunplus, Sitronix, Samsung, and Epson.
At the current time we use the SPLC780D (Sunplus) or the ST7066 (Sitronix) controller driver on all our Alphanumeric (Character) LCD Displays.
Our Standard list of Character displays includes 8 x 1 LCD Display, 8 x 2 LCD Display, 16 x 1 LCD Display, 16 x 2 LCD Display, 16 x 4 LCD Display, 20 x 2 LCD Display, 20 x 4 LCD Display, 24 x 2 LCD Display, 40 x 1 LCD Display, 40 x 2 LCD Display, 40 x 4 LCD Display,
Static displays do not come with the controller driver on board. The customer supplies the driver on their printed circuit board. Our Standard list of segment displays (glass liquid crystal displays) include 7(seven) segment LCD display, 14(fourteen) segment LCD display, and 16 (sixteen) segment LCD displays.
The majority of our LCD modules have the options of TN, STN, and FSTN. Backlight options include EL and LED (transflective and transmissive).
