TFTs / Re: Pin reversal NHD-1.8-128160EF-CTXI#-FT?
« on: February 27, 2017, 10:03:03 AM »
As a professional, I draw the plugs as a separate part using the manufacturers number, then the schematic application specific symbol using their numbering and connect the two. On some occations the manufacturer's numbering is not there, or missing, causing doubt and confusion but at least makes me aware about the doubt, but in this case they seems to be reversed, wich is even more confusing as I got no clear alert. I should note that it is not common for the professional designer to have the part in their hand before designing the pcb. In this case a simple picture put me on a lead, wich is not really giving much confidence. A picture is easy to mirror. But the picture of this module at digikey didn't show a mirrored image and gave some confidence.

Luckily I accidentially found out about this mismatch before it was too late. I just needed a confirmation that the plug datasheet numbering was reversed to the TFT's datasheet pin numbering. I got reasons to doubt the TFT datasheet [because of poor electrical specs], so I thought I better get this confirmed. I know these chinese parts have poor datasheets in general so I should have been alert much earlier.

TFTs / Pin reversal NHD-1.8-128160EF-CTXI#-FT?
« on: February 27, 2017, 05:06:37 AM »
Toward the end of our product verification, I coincidently verified our design towards the image of the NHD-1.8-128160EF-CTXI#-FT
I noticed that the image had the touch pins to the right hand side of the screen (when viewed with connectors pointing down and facing image side), while our design seemed to have them on the left hand side.
The picture of the module tells me that pin1 needs to be on the left hand side, but when I plug that into the suggested molex plug with contacts on top, the molex datasheet suggest pin1 will be on the opposite side.
Attached is a collage of the two datasheets to indicate the problem.

Can you please confirm this is the case, or did I get something mixed up?

New Product Wishlists / High framerate < 3" lvds fed color
« on: April 01, 2016, 03:11:27 PM »
Looking for a small, less than 3" display module that can be driven with few wires at high speed from an FPGA.
18/24bit color, up to and even beyond 200Mhz LVDS serialized RGB, but i2c for command port.
Potential:1k++/year
