Please post your source. Where did you read it?Could you please explain me what mean negative voltage in lcd terminology? Because I read that tft transistor is switched OFF by negative voltage (-6V). But what is difference between possitive and negative voltage in this case?
Thanks
http://www.personal.kent.edu/~mgu/LCD/tft.htm - here I read about negative voltage which swich OFF tft transistor
-but I couldnt find article, where I found that it is -6V
Well then it would be very helpful if you find the article talking about -6V again and post a link here.Sorry, but in first article I wrote, that I read it, but I see many articles per day and I cannot remeber on it. And this is clear for me, but I dont know what mean negative voltage in tft terminology. I read that in lcd is Vcom like ground and Vcom has about 7,5V. So this -6V is what? Is it minus because Vcom is 7,5V and it is under or because it is on another side of source?
Thanks
