Densitron 4307BG-HNY - Large 4 line by 20 character LCD

 This listing is for all 13 displays as a job lot and, as such is an absolute bargain. 

We used to use these display modules in a custom made data logging machine. When that contract came to an end we had 13 brand new units left over. The photographs include a used unit which shows what the units look like. The ones for sale are brand new, unused and still in their original packaging. The following data is taken from the datasheet and should tell you everything you need to know.

 

Dot matrix display module consisting of a Liquid Crystal Display, CMOS driver and controller LSI, printed circuit board, metal support frame and array type Light Emitting Diode (LED) backlight.
