Hi All,

I’ve got an Optrex 16433-CEM LCD fo 10$ :slight_smile: and I don’t know how to connect it can you help me?  I have connected pins except these:

Display datasheet

No. Symbol Level Function

1 VSS - Power Supply (0V, GND)

2 VCC - Power Supply for Logic

3 VEE - Power Supply for LCD Drive

4 RS H / L Register Select Signal

5 R/W H / L Read/Write Select Signal H : Read L : Write

6 E H / L Enable Signal (No pull-up Resister)

7 DB0 H / L Data Bus Line / Non-connection at 4-bit operation

8 DB1 H / L Data Bus Line / Non-connection at 4-bit operation

And how should I connect that backlight thingy ??? I don’t even know what backlight type is it. And witch side should be on top?  It looks that silver side should be on top  as its pins then are in right direction to fit there.

Thanks

huummm I can’t wee why you didn’t wire all the connector?

VCC -> Vd and VEE->V0

fir the backlight : Where did you get it pleasE??? I’m very interested in that!!! and is it a led backlight? of ot’s EL backlight you’ll need a converter…

That’s an EL backlight.  The white side is probably the light up side, and you do need a convertor to drive it.  

Have fun!

Thanks. :slight_smile:

Now can you say how to make that EL inverter? :wink:

Hi,

I found something at http://www.geocities.com/talkingelectronics/EL-Inverter-Project-P1.html

but it is for 3v and I can’t find its components here.  Are there more EL Inverter’s circuts ???

6

I am maybe wrong but, it camera’s flash, those you use only once, there’s this kind of circuit

7

No it’s an inverter for lighting EL plates and wires. I found everything except the transformer. Who can help me building an EL inverter  or I’m only with EL here??? And what should display my LCD when it’s connected with core without PIC?

Thanks

what should display my LCD when it’s connected with core without PIC?

nothing!

Who can help me building an EL inverter

I think the easiest way is to buy an EL inverter…

9

But the biggest problem is that I cannot find any here in my country :cry: . So I think I can build it  ;) . But I don’t know how. Can somebody help me?

Thanks

have a look on ebay, sometimes there’s one to buy.

I don’t know if it’s always the same output volatge… 160V?

Yeah Pilo; Im sure I have seen somewhere a circuit from a disposable camera used to do this job I think it was in a magizine; they were talking about going to photo-labs to get the old camera cases, pull the circuit board out make one small mod and you had an inverter ???

Cant remember which publication tho!
