i am new to modding comptuer cases, but i am looking for a LCD 20x4 that is blue negative. (i think i said that right .. black background with blue characters)

i know in the mod that is posted around the internet as well this forum that the guy mounted a external lcd screen on a mic stand he used a polorizor screen... does anyone know where i can get one?

can i use the blue lcd screen and use it in replacment of the 20x2 serial screen that you can get here?



my ulimate goal is to be able to use the software that is availiable for serial LCD's but with a blue negative screen 20x4
please let me know of any ideas you may have.

thanks

Some LCD colours all done by replacing backlight LEDs :) (all done using very bright single leds).

A light blue led (1500mcd)




A new (wooow!) blue/green led (3000mcd)




A white led (1560mcd) - brighter than the original white one



An orange/red led (3000mcd)




An orange led (3000mcd)




A yellow led (11000mcd!!)

bgmicro ones work fine youll just have to wire them up yourself
to get it backlit, you need an inverter and some el sheet
