rambinator Posted November 8, 2005 Report Share Posted November 8, 2005 Hi!My 2 2x40 lcds have 4 holes on the pcb for screws. On most of the designs in the gallery which have these displays I don't see any screws next to them. how did you attach the displays then?

pay_c Posted November 8, 2005 Report Share Posted November 8, 2005 There are more than one possibility.Easy: Just attach it directly to the frontplate. If you don´t want to have the screws on the frontplate (which are not soooo bad I think) you can also attach the LCD to a breadboard (is it called like that? German: "Lochrasterplatine") which itself is attached to the frontplate with less screws (also all the buttons and LEDs and stuff are on the breadboard). You could look at some pictures of my MBSEQ (on UCApps.de) to get an idea what I mean. There everything is built on a breadboard which itself is attached to the frontplate.There are also other possibilities you could think of (like glue it to the frontplate) - but all more or less .... :-\Greetz!

Davo Posted November 8, 2005 Report Share Posted November 8, 2005 A breadboard is a white thing with sockets for temporarily mounting parts for testing the viability of a circuit. Perfboard is a sheet of fiberglass or phenolic with holes punched and usually nothing else. Quote Link to comment Share on other sites More sharing options...
rambinator Posted November 8, 2005 Author Report Share Posted November 8, 2005 Well I can't mount the lcds on a vectorboard because I allready soldered sockets at the backside and it would be quite difficult to mount it on the same board as the encoders.i think it would be wise then to use the lcd's holes with screws Quote Link to comment Share on other sites More sharing options...
Fx3_hdrive Posted November 8, 2005 Report Share Posted November 8, 2005 u can tap the holes in your panel if u havent drilled them out yet, that way u can screw the screws for the lcd from inside (with spacers of course) and have the ends of the screws flush with the surface. thats what i'm going to do on mine :)Yarek TEDIT> random bits and stuff Quote Link to comment Share on other sites More sharing options...
pay_c Posted November 9, 2005 Report Share Posted November 9, 2005 Aaaaah! Vectorboard it was! ;D Thnx!Although there´s already a socket there, it´s still no prob: Just drill the holes of the vectorboard, where the socket would hit, to a diameter of about 3 mm. The socket will slide through and can be connected as normal and the LCD will be flat on the vectorboard. Quote Link to comment Share on other sites More sharing options...
rambinator Posted November 9, 2005 Author Report Share Posted November 9, 2005 unfortunately the socket is a "wannenstecker" it looks like this:and it's part of a complicated display-cable which was necessary due to the strange pin-assignmentit would only be possible to saw out a square hole i think Quote Link to comment Share on other sites More sharing options...
pay_c Posted November 10, 2005 Report Share Posted November 10, 2005 Yes, I know these LCDs. Still: If you drill the appropiate holes (or cut out a rectangular) you still can put them on the vectorboard. Just make two things sure: 1st that there are still enough holes for fixing the LCD (four screws, right?) and 2nd that the stability of the vectorboard is not decreased to much (once one of my vectorboards broke of at the edge because I tried to fix the LCD like that - there were only two rows = 5 mm left at the border and that was not enough at all).Or you really attach it to the frontplate. ;DGreetz Quote Link to comment Share on other sites More sharing options...
