I have just aquired a Toshiba TLX-1741-C3B for my media centre PC project.

Im just not sure what i need to get started.....this is what i think i need

1) wire up the control port on the thing to the specs of the schemeatic for the T6963C on this site.
2) find me a -8v power source. (maplins or RS)
3) a power source for the backlight i have an invertor from a scanner that should work.

is there something im missing or if someone could point out where i can get the right power sources from that would be grand....

Thanks

The pinout of that display seems to match the TLX-711A here:

EXCEPT that pin 20 is REVERSE input. If you connec this to +5v you get positive image and if you connect it to ground you get negative image.

Also the typical VDD-VEE voltage is 18.5V in the datasheet. This would mean that with +5v VDD you need at least -13.5V VEE negative voltage.

where could i get a power source from and what am i looking for, could i use a transformer from anuthing i find around the house and how to i get a -13.5v from a transformer?

Sorry about 20 questions i didnt do much electronics in school but i did a bit even thought it was 9 years ago

just to bump this thread up to the top, i am thinking of getting this project back on.


I am assuming to get the -13.5v i need i just conect it to the - side of the transformer or am i way out as thats all i can think of.

You can trying using a 5Vdc Pwr supply and then a -15V voltage regulator connect to a Trim, so that your are able to adjust contrust.

like described in the link, just look for a regulator that will meet your needs, you will have build a simple circuit on a PCB to get the voltage though; its the only way!

thanks for your reply.

Figure 3 looks right for me, i have tinkered with protoboard before what size would be enough for this 6x4in?


Thanks again
