content: For one of my projects which uses the Hammond RM2015M enclosyre I was looking for the smallest possible alphanumeric LCD. I found two1. Everbouquet MC0802A-SGR-4, 8x2 LCD without backlight, dimensions 25.0mm(W) x 17.5mm(H) x 4.3mm(D), price around 10-12USD2. Oriole 16216-8SL, 16x2 LCD with LED backlight, dimensions 53mm(W) x 20mm(H) x 8mm(D) price 5-6USDWhile I like the Everbouquet display, the lack of mounting holes was a problem, which forced me to try out the Oriole LCD. If anyone knows of other small(physically) alphanumeric displays post a reply here.

content: You want the "smallest possible", but how many characters/lines do you need?If you need them in large quantity ask one of the many custom display manufacturers.

content: A two line display with 8-16 characters/line.I did check with one of the manufacturers (Oriole) whose prices are reasonable. For custom LCDs they have a initial development charge of 1500-2000USD. Even for a modified PCB it is not cheap unless I place an order for 2000 nos.Quote from: amyk on August 15, 2012, 10:29:30 am

content: Quote from: Monkeh on August 15, 2012, 03:46:26 pmActually not. Finding LCD displays with less than 25mm height is not so easy. The 8x2 on ebay is standard 30mm height which is a bit large as opposed to 17.5mm for the MC0802A and 20mm for the 16216-8SL.

But yes, if you need 25mm or less, things are harder to find, they may take as long as two minutes:http://www.powertip.com.tw/products_2.php?product_id=1171043916&area_idbk=1170985616Here's a couple more for you:http://uk.farnell.com/batron/bthq21603v-sre-wc/lcd-module-alphanumeric-16x2/dp/9448675http://uk.farnell.com/midas/mc21605f6we-spr/lcd-2x16-stn-reflective-5mm/dp/2063246

content: The Batron BTHQ21603 and the Powertip 1602 are identical to the 16216-8SL from Oriole both in dimensions and connectivity (they use FFC). The BTHQ21603 costs INR 1,370.09 (almost 25USD) from element14 India.The MC21605 is 30mm height and even if I spend more than 2days it is not likely to shrink in size.

content: You never said FFC wasn't allowed. Picky, aren't we?The Midas was a mispaste, I can't seem to find the other one I was looking at now.E: Midas do a number of small units which do not have screw mounts. They seem to exclusively use I2C (less wires! The horror!).

content: Quote from: Monkeh on August 16, 2012, 11:08:56 amI never said I was against FFC. In fact I am using the Oriole 16216-8S in my project. I am just looking for alternate types. Not the same type from different manufacturers. And of course mounting holes.

content: Quote from: joseph.anand on August 16, 2012, 11:52:52 amI think you'll find there are very few non-standard form factors out there. If you look for ones which are I2C controlled rather than limiting yourself to HD44780 compatible interfaces, you may find some others.
