GLCD S1D13700 Is not displaying anything.
Moderators: David Barker, Jerry Messina
This is my datasheet:
http://www.displaytech.com.hk/upload/pr ... es-v21.pdf
I have measured the voltage on Vout PIN and it´s +27,5V without connect.
Vee is 0V.
I think that my display works with positive voltage values...
Can you check my datasheet and confirm it please??
It's very important....
Once again, thank you so much....

I just send them a mail asking for some help...

People with GLCDs like mine (240320H) don't have any problem.
The difference is in DC/DC converter....(They don't have it)
So, they have to insert externally the voltage level (+26 V).
Perhaps, with an external power supply appears something!!
I still thinking that the current that come out of the DC/DC for driving the LCD (contrast) is very low (0,7 mA).
What's the Ilcd current in your display with the best contrast??
