SPECIFICATIONS FOR LIQUID CRYSTAL DISPLAY MODULE MODEL NO: 12232-10 1.10 LCM Application Notes The Epson SED1520 (or equivalent Avant SBN1661G) is used on many Pacific Display Devices GDM 12232 family modules with 122 segments and 32 commons. Extrapolating the information needed to interface to these ICs on the standard module might be a bit difficult from the Epson documentation. Here is a brief that may speed your progress. Duty Cycle: Set the Duty to 1/32 (D=1).

PRECAUTIONS FOR USING LCD MODULES Installing LCD Modules The hole in the printed circuit board is used to fix LCM as shown in the picture below. Attend to the following items when installing the LCM. 1) Cover the surface with a transparent protective plate to protect the polarizer and LC cell.
SPECIFICATIONS FOR LIQUID CRYSTAL DISPLAY MODULE MODEL NO: 12232-10 3) If soldering flux is used, be sure to remove any remaining flux after finishing to soldering operation. (This does not apply in the case of a non-halogen type of flux.) It is recommended that you protect the LCD surface with a cover during soldering to prevent any damage due to flux spatters. 4) When soldering the electroluminescent panel and PC board, the panel and board should not be detached more than three times.
SPECIFICATIONS FOR LIQUID CRYSTAL DISPLAY MODULE MODEL NO: 12232-10 Storage • • • • When storing the LCD modules, avoid exposure to direct sunlight or to the light of fluorescent lamps Store the module in a dark place where the temperature is 25 oC ±10 oC and the humidity below 65% RH. Do not store the module near organic solvents or corrosive gases. Do not crush, shake, or jolt the module (including accessories).
