Hi.
I want to drive NOKIA 5800 LCD with microcontroller but my problem is pinout details of LCD connector.
I mean, I have no documents or datasheet of it to undrestand about timing and protocol of LCD pins.
I also downloaded the relevant files like "Nokia service manual"(LCD pinout attached), but i cant undrestand CDP0 ck- or CDP0 ck+??
Why positive and negative is used??
Thanks a lot.

 

Hello,

It could be that the signals are given in a LVDS manner:

Thanks Bertus.

This means that i can use 2.5v IO voltage level with differential technique(one pin 0v and another pin 2.5v and upside down?)


What do you think about the timing of the signals?

Hello,

Does the manual you got say anything about the levels?
On the wiki page there is only a differential voltage of 350 mV mentioned.

There is no describtion in the manual for this(voltage level) but i red in wikipedia(your shared link).

Hi.

Does anyone know about this?
