This kit consists of a CFAF320240F-035T a 320x240 3.5" Full Color TFTLCD module mounted on a carrier board (CFA-10074). The carrier board supports a current driver for the LED backlight of the display.
We also have this same module and carrier board with a touchscreen.
The LEDs used in the backlight for the CFAF320240F-035 family of TFT LCD modules and any assemblies using the CFAF320240F-035 family of TFT LCD modules produced from 2011-03 to 2011-11 is no longer available. To avoid any interruption in supply for our customers, we have gone back to using the LEDs which were in the backlight assembly prior to that point. The LEDs now used are more toward the blue end of the spectrum, whereas the LEDs used for the March-November 2011 period were toward the red end of the spectrum. There may be a difference in light output, but still in the specified range from our datasheet.
Reason:
Component end of life.
Impact:
Low. The specifications for the LEDs used in the backlight still meet the specifications stated in our datasheets.
Availability:
Current stock.

Part Change Notice #10403: Glass characteristics change requiring single command initialization change for optimal contrast.
Glass characteristics change requiring single command initialization change for optimal contrast.
Description:
PCN for CFAF320240F family of products due to a change in panel vendors.
Reason:
In order to maintain uninterrupted supply of this module, we changed vendors for the LCD panel so that lead times would not be affected.
Impact:
Because of the slightly different characteristics of the panel, a single command in the initialization of the module should be changed so that optimal contrast can be achieved.
No other changes are necessary.
Recommendation:
Change the following registers from:
write_command(0x001E); // Power Control 5
write_data(0x00B7); // Page 53 of SSD2119 datasheet
to
write_command(0x001E); // Power Control 5
write_data(0x00BE); // Page 53 of SSD2119 datasheet
and contrast should be optimal for the display.
Availability:
Immediately for non-touchscreen modules, with a cut-in for the modules with a touchscreen over the next several months.
Price Change:
Pricing is not affected by this change.
