Hi all, I didn’t see any guides about this on the site, but thought I would share that there is a bolt-in OLED replacement display for the K1000; no cutting, drilling or other heavy mod work needed. Though you likely will have to solder a new right angle 14 pin connector on the new display, depending on who you get it from. The one I found is the Winstar?WEH001602DWPP5N00000. There are variations on the number for the text colors, but the series is the same. Here’s a photo of the stock Seiko display (on top) and the Winstar (bottom):
Once bolted in and plugged in, here’s how it looks on my K1000:
Some semi-fiddly things to note are that on the 14-pin connector for the display, pin 3 (which was the display contrast adjuster on the LCD) is not used, and neither is the purple wire power tap from the transformer for the backlight. I taped over the transformer end of the connector that joins the display wires to the ones from the transformer, to ensure no risk of shorts before wire-tying it down.
Since I did this, I learned that Winstar has a new model of this same display, WEH001602DWPP5N00100. The specs look to be the same. The above model number is for white type on a black background, but other colors are available too.
Hope this helps, David

David,
The group ran into the Winstar displays a few years ago -- see /g/K1000-K1200/topic/1000px_display_backlight/81012051?p=
-- and the problem then was the same as now: none of the major
distributors in the US even acknowledge the existence of the 2x7
header version.? (Some do stock the 1x16 header version, which is a
bit more challenging to adapt than most folks want to deal with,
although I've installed them on several 1000-series modules that
were brought to my shop for service.)? Pricing from European
distributors in 2021 was around $10 USD, but shipping across the
pond cost 4 times more than the display.
If you know of a US vendor that carries these, let me know, and I'll
be stocking up on them !
Regards,
Brian

This search on Mouser shows some 16x2 displays with the correct outside dimensions, a 2x7 header, and 5V supply.
I don't know if they meet the other requirements.

Which unit are we talking about from Mouser? Patrick

Any 1602 module that uses the Hitachi HD44780
LCD controller will work (some requiring modification), but I was
specifically asking David about finding OLED versions in the US.
These are standard LCD modules.

Thank You. ?I’ve done these on my k1000 and used the ones by CrystalFontz. ?They work very well. ?but I ?wasn’t sure about the pinout. ?Sometimes the + 5 v is switched between post 1 and 3. ?

The Winstar OLED displays from Crystalfontz were the ones I'd been
getting, back in the day.? They were out of stock for quite a while,
so I'd given up on them. Seems that they're back, at least for the
time being, so thanks for the reminder!?

You’re welcome. ?I did get a few 1602 led displays from them about 8 months ago when I changed out my 1000 modules. ?It appears they’re still stocked up and doing well. ?

This OLED is not from a US source but from China:
?
?
If the URL doesn't work you can search Aliexpress.us for 3256807774480278 or WEH001602A.
?
It may as well be a US source as I ordered it on 1/14/25 and it arrived today 1/24/25, 10 days later. The Aliexpress store is "Rock Optoelectronics Technology" and the OLED is listed as:
?
16x2 COB OLED Character Display 3.3-5V SPI Serial Parallel Port Driver WS0010 Scandinavian European Cyrillic Russian Font
?
Item description:
?
WEH001602A Winstar 16x2 COB OLED Character Display 5V power supply Controller WS0010 new and original
?
My cost for the green one with shipping and "tax" was $20.60 and I paid via PayPal. Other colors are available as well.
?
It looks just like the one that David posted and much to my delight I found it to be a 100% drop-in replacement for the original Seiko M1632 LCD. You do have to solder on a double-row 90 degree header just like the one that is on the Seiko. No need to worry about pin 3, it's not connected on the WEH001602A.
?
Here it is on my K1200:
