USB LCD Displays
This product has reached end of life and has been replaced by CFAG12864U3-TFH
(EOL) 128x64 SPI Graphical LCD
Part Number: CFAX12864U1-TFH
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)
- Built-in Novatek NT7534 controller
- Great for handheld instruments, cell phones, PDAs, etc
- Ultra low power consumption
- Demonstration board available here: DMOX12864U1TFH
- RoHS Compliant

Product Update #10867: Extended Last Time Buys until Oct 31, 2017
Product Update #10863: End of Life Announcement with Last Time Buys
Product Update #10728: CFAX12864U and CFAX12864U1 series backlight improvements.
| Products Affected: | CFAX12864U1-TFH, CFAX12864U-TFH |
| Date Issued: | July 27, 2016 |
| Summary: | CFAX12864U and CFAX12864U1 series backlight improvements. |
| Description: | 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. To determine the date code, please see the attached document How to read CFAX12864U and CFAX12864U1 Date Codes.PDF |
| Reason: | 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. |
| Impact: | Reduced current requirements values will effect current driving circuitry. Increased luminosity values will effect visual appearance. |
| Recommendation: | Test engineering samples when available to evaluate backlight circuitry changes and settings for visual consistency. |
| Availability: | 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. |
| Price Change: | No price change is currently scheduled. |
