      Hi,

      I have been asked to improve an LCD screen graphic, and send the updated files to China.

      I require images for the LCD screen, and I am unsure of
      a. The filetypes used to create LCD screen layouts
      b. Libraries or images that can be used for the LCD graphics

      I am doing this through a 3rd party, so I am struggling to get information on this quickly.

      Can anybody help?

      Kind regards,
      John Biddleston

      Impossible to say without knowing more about the kind of hardware the LCD is part of, and what software created the original screens. The software is usually supplied (or specified) by the hardware manufacturer, and the filetypes (usually a proprietary format) depend, of course, on the software used.

      The LCD is a Santek PN SS0204B1-TG-6P

      Its just a very very standard LCD reflective display, like those used in calculators.

      Now, I realise that the hardware maker might specify a certain drawing format. That is my question? Which ones are typically used.

      I explained that I am getting this 3rd hand, as I am doing this for a 3rd party, and although the question has been asked, the information is not forthcomming as quickly as I would like. I want to get started.

      I think that there must be some information on typical packages used? I can't imagine that each manufacturer uses a different package. Is it going to be AutoCAD DXF for example, or maybe AI format or Correl?

      Also, I want to find graphic library files that I can use for this. Surely whatever package I use to do the image in, I can import suitable library files and convert. So if someone can recommend a source for suitable library files this would be useful. I just want icons and graphics from a searchable library, and possibly also any tips from anyone who has done this type of thing.

      I don't think that this is an impossible request??!

      I suggest you contact Santek and ask them.

      Like this sort of thing?

      My assumption would be that some kind of specialist software is involved, perhaps software that can convert a graphics file to this format.

      Had a quick rummage around on the web and found this:
      http://www.microchip.com/en_us/technology/graphics/
      There's a free graphics creator you can download. Hope this is of some use or can at least give you some ideas...

      Your approach will partly depend on whether the display has custom segments such as 7 segment alpha-numeric, icons etc. or is a matrix of square pixels. Calculators sometimes use both.

      In my experience the supplier will accept .ai (illustrator) format and sometimes .cdr (Corel Draw). They'll probably also take dxf.

      A library might be handy for a 7-segment although they're also quite quick to draw, especially if you google image '7-segment display' and trace it in Ilustrator or CorelDraw.

      Hope that helps.

      the best way to transfer files to an LCD supplier is a DXF extension (you have to get your part parametric first so you can easly change it), you can generate them from any CAD software. For the LCD content I reccomend to work closely with your supplier and go through all the details in order to make sure you`ll get what you want on it.

      Thanks. I think that you are right.

      DXF should be pretty much universal, and whatever they use, I cant see how they can't import DXF anyway.

      I use Solidworks, so I am also thinking that doing the work in parametric would be easy to modify and draw, and then I can export from 'drawing sheet' as DXF and others anyway.

      Still no reply from supplier, so I am going to go ahead and complete this over the weekend. Thank you for your answers! :D
