Make connections to your PCB using Pins 19 (A (LED+) and 20 (K (LED+) on the display module's connector.

The CFAG12864B-YYH-N CFAG12864B-YYH-N backlight uses LEDs. The backlight is easy to use properly but it is also easily damaged by abuse. NOTE Do not connect +5v directly to the backlight terminals. This will ruin the backlight. NOTE We recommend that the white LED backlight be dimmed or turned off during periods of inactivity to conserve the LEDs' lifetime. LEDs are "current" devices. The brightness is controlled by the current flowing through it, not the voltage across it. Ideally, a current source would be used to drive the LEDs. In practice, a simple current limiting resistor will work well in most applications and is much less complex than a current source. You need to know what the supply (forward) voltage of the LEDs will be so you can calculate a current limiting resistor (RLIMIT). The forward voltage will vary slightly from display to display.

ESD (ELECTRO-STATIC DISCHARGE) The circuitry is industry standard CMOS logic and susceptible to ESD damage. Please use industry standard antistatic precautions as you would for any other PCB such as expansion cards or motherboards. DESIGN AND MOUNTING The exposed surface of the LCD "glass" is actually a polarizer laminated on top of the glass. To protect the polarizer from damage, the CFAG12864B-YYH-N CFAG12864B-YYH-N ships with a protective film over the polarizer. Please peel off the protective film slowly. Peeling off the protective film abruptly may generate static electricity. The polarizer is made out of a soft plastic and is easily scratched or damaged. To protect the polarizer from damage, place a transparent plate (for example, acrylic, polycarbonate, or glass) in front of the CFAG12864B-YYH-N CFAG12864B-YYH-N leaving a small gap between the plate and the display surface. We recommend GE HP-92 HP-92 Lexan, which is readily available and works well. Do not disassemble or modify the module. Do not modify the mounting tab of the metal bezel or make connections to it. Solder only to the I/O terminals. Use care when removing solder-it is possible to damage the PCB. Do not reverse polarity to the power supply connections. Reversing polarity will immediately ruin the module. AVOID SHOCK, IMPACT, TORQUE, AND TENSION Do not expose the module to strong mechanical shock, impact, torque, and tension. Do not drop, toss, bend, or twist the module. Do not place weight or pressure on the module. IF LCD PANEL BREAKS If the LCD panel breaks, be careful to not get the liquid crystal fluid in your mouth or eyes. If the liquid crystal fluid touches your skin, clothes, or work surface, wash it off immediately using soap and plenty of water. Do not eat the LCD panel. CLEANING The polarizer (laminated to the glass) is made out of a soft plastic and is easily scratched or damaged. Be very careful when you clean the polarizer. Use the removable protective film to remove smudges (for example, fingerprints) and any foreign matter. Do not clean the polarizer with liquids. Do not wipe the polarizer with any type of cloth or swab (for example, Qtips). Damage will be especially obvious on "negative" modules (module that appear dark when "off").

This module is not "user friendly" and connecting them to a PC's parallel port is often difficult, frustrating, and can result in a "dead" display due to mishandling. For more information, see our forum thread at http://www.crystalfontz.com/forum/ showthread.php?s=&threadid=3257. Your circuit should be designed to protect the module from ESD and power supply transients. Observe the operating temperature limitations: a minimum of -20°C to +70°C maximum with minimal fluctuations. Operation outside of these limits may shorten the life and/or harm the display. At lower temperatures of this range, response time is delayed. At higher temperatures of this range, display becomes dark. (You may need to adjust the contrast.) Operate away from dust, moisture, and direct sunlight. STORAGE Store in an ESD-approved container away from dust, moisture, and direct sunlight. Observe the storage temperature limitations: a minimum of -30°C minimum to +80°C maximum with minimal fluctuations. Rapid temperature changes can cause moisture to form, resulting in permanent damage. Do not allow weight to be placed on the modules while they are in storage.
