I'm guessing the original question was about simple glass and tin oxide passive LCD displays like on calculators and microwave ovens, not active-matrix displays for TVs and notebook PCs. The former don't require high resolution or precision, certainly none higher than for higher-end PC board fab.

Re: [PEDA] Designing Masks for LCD displays
Ive used Protel to design office layouts and bookcases with so I guess you could use it for LCD masks. What format does your mask shop require. Do you have the process design rules and can you translate these to rules that Protel understands? Its basically just a bunch of polygons and vias and layers making up primitives. And its got all sorts of weird spacing requirements between different layers and vias. Id imagine you would have to design using 1:1 zoom level. Ive no idea what process size you would use 1-2 micron? The designs here are done at a standard size, then shrunk to the process size. Then DRC/LVS, simulated using spice modals and expected silicon speeds and temperatures - corners. A schematic may or may not be required and how would you get the nets to the PCB primitives and how would it be DRC'd? __ Clive Broome IDT Sydney Design CentrePh: +61 2 9763 3513 8 Baywater Dr, Homebush Fax:+61 2 9763 3409 Sydney, NSW, 2127 Email:[EMAIL PROTECTED] Australia ___ "Mark Koitmaa" <[EMAIL PROTECTED]> on 02/27/2002 04:19:08 AM Please respond to "Protel EDA Forum" <[EMAIL PROTECTED]> To: "Protel EDA Forum" <[EMAIL PROTECTED]> cc:(bcc: Clive Broome/sdc) Subject: [PEDA] Designing Masks for LCD displays Does anybody have experience or opinions about designing masks for LCD displays using Protel?

I'm sure you could do this with no problem. The Gerber output should be usable by an LCD maker, but I don't know what they traditionally expect, Gerber or Calma format. (Calma is used by the IC mask people.)

Re: [PEDA] Designing Masks for LCD displays
Yes, exactly. I have a general idea of the requirements but don't know the details, such as type and format of CAM data required to manufacture the masks (these will be for 4" wafers). We may have a contract job for someone with this kind of experience. Mark Koitmaa, C.I.D.

Re: [PEDA] Designing Masks for LCD displays
Do you mean for custom LCDs? I know a guy that did it on a Mac using Macpaint (a long time ago). I'm sure you could do it with Protel. :) Tony > -Original Message- > From: Mark Koitmaa [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, February 26, 2002 10:19 AM > To: Protel EDA Forum > Subject: [PEDA] Designing Masks for LCD displays > > > Does anybody have experience or opinions about designing masks for LCD > displays using Protel?
