Accessories / NHD-C12864WC-FSW-FBW-3V3-M Mounting
« on: December 04, 2015, 10:32:14 AM »
In looking at the mounting flanges for the unit, the hole diameter is 5.9mm or 0.225 inches. An appropriate screw for that size would be like #10 hardware. That seems awfully large.

What is the "normal" method of mounting these displays? Can you recommend some specific hardware?


New Product Wishlists / Series LED for backlighting

We are planning on using the NHD-C12864WC-FSW-FBW-3V3 for a new design. However, the ability to control the backlight level in firmware is important. Would it be possible to get this in a series configuration? This would increase the LED voltage to some multiple of 3V and then we could use switching technology like the FAN5333 to control the current.

Note that we chose the display based on it's overall size and it fits the selected case perfectly.


Graphic LCDs / Driving the backlight LED for NHD-C12864WC-FSW-FBW-3V3

The LED voltage for the NHD-C12864WC-FSW-FBW-3V3 is specified as 3.0V at a current of 36mA. Does this mean that there is an internal current limiting resistor? None is shown in the drawing.

Although I don't expect to go there, what is the maximum current for the LEDs? (I plan to use a dimming circuit that will allow the user to adjust the backlight.)
