Graphic LCDs / FSTN(-) 128x64 pixels 66x33 mm with RED color?
« on: May 23, 2016, 04:41:42 AM »
Is there any display like this:
39 US$

But with RED color instead of white?

Serial interface would be preferable too but is less important.

Is there any way to get to, and replace the LED without removing anything that holds the actual glass substrate?
I suspect the metal frame on the top is the one that holds the display glass in tight contact with the electrical connections.

That works nice if the display has a RGB feature. But suppose I want a display with FSTN(-) 128x64 and the NHD-12864WG-FTTI-VZ#000 is the only one that matches that. But it only features a white LED backligtht, no RGB, and I need the red backlight. Is it possible to open and switch the physical LED used?
That would make many more displays a possible choice.

Because as I understand it. Most of these dot matrix displays uses a light guide which ends at the side where a LED is located. Thus it should be relatively easy to get to.

As far as I understand, dot matrix LCDs use a backlight LED that lights up the active display area through a optical guide. And this is located on the side. Shouldn't it be possible to replace it with another color?

Here's a dot matrix example:
