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