This is an extremely low-power 128x64 graphic LCD display module. With its integrated white LED backlight, illuminating the display is no problem in low-light conditions. This display is perfectly suited for hand-held, or any application requiring low power consumption or a very thin display. The top of the display automatically shows a row of icons without your having to render them. This module has an integrated controller and its tail is designed to mate with standard 18-conductor 0.5mm pitch ZIF connectors (typical would be Omron XF2L18351A/ DigiKey P/N OR754CT-ND).
Ultra thin and light TAB construction
Form, and Function compatible with CFAX12864CP1 series of LCD modules
Wide temperature range: -20°C to 70°C (-4°F to 158°F)
CFAX12864U and CFAX12864U1 series backlight improvements.
The white LED backlight of the Crystalfontz CFAX12864U and CFAX12864U1 series of compact graphic display modules is changing as a result of manufacturing improvements of white LEDs and backlight assembly. The changes are as follows:
Forward voltage: Old value 3.5v -> new value 3.5v – NO CHANGE
Supply current (typical): Old value 48mA -> new value 40mA – 17% decrease
Luminosity (typical): Old value 150 cd/M^2 -> new value 570 cd/M^2 – 280% increase
Uniformity (typical): Old value 80% -> New value 90% - 12.5% increase
Note: With 16mA of supply current, luminosity is rated at 250 cd/M^2. This is a 66% decrease in current with a 66% increase in luminosity.
Display modules with a date code of 08/01/16 (August 01, 2016) will have the new backlight. Date code prior to 08/01/16 will have current backlight.

As part of our continuous improvement, design changes have been made to the white LED backlight of the CFAX12864U and CFAX12864U1 for improved luminosity, and reduced current profile.
Reduced current requirements values will effect current driving circuitry.
Increased luminosity values will effect visual appearance.
Test engineering samples when available to evaluate backlight circuitry changes and settings for visual consistency.
CFAX12864U and CFAX12864U1 display modules with new backlight should begin shipping at the end of Q3 2016.
Engineering samples for testing / validation will be available during this same time frame.
